A kyphoplasty balloon catheter shortlist is useful only when its model differences can be translated into clear evaluation and purchasing criteria. For hospital and distributor buyers assessing CHANGMEI Kyphoplasty, the four models covered here—KB0115, KB0120, KB0120S1, and KB0210S1—differ in stated length, inflation volume, gauge, marker spacing, or balloon construction. The available specifications support a product-level comparison; they do not, by themselves, establish clinical superiority or determine suitability for an individual patient.

Jiangsu Changmei Medtech Co., Ltd. manufactures the kyphoplasty balloon catheter products discussed in this reference. The comparison is intended to help procurement teams, distributors, and clinical stakeholders organize questions before product qualification, stock planning, or order confirmation. It is not a substitute for the product label, instructions for use (IFU), local regulatory requirements, or a clinician’s assessment.

The procurement question: which specification matters for this requirement?

For evaluation-stage buyers, the practical starting point is not to treat the model codes as interchangeable. First identify the required gauge and the model-specific dimensions or features that must match the intended product configuration. Then verify those details against the current technical file and purchase documentation. This approach keeps the comparison grounded in observable specifications instead of assumptions based on a model name or a broad category description.

The supplied model information identifies two 6 cc options, KB0115 and KB0120, and two 11G, 3 cc options, KB0120S1 and KB0210S1. It also gives distinct length or marker information for selected models. The information supplied does not establish that every specification applies to every model, so buyers should not transfer a feature from one model to another without documentation.

At-a-glance model comparison

This table reproduces the model details supplied for this article. Where a detail is not listed for a model, it should be treated as unconfirmed here, not inferred from another model.

How the four models differ

KB0115: a 6 cc model with specified marker spacing

KB0115 is described as a 280 mm kyphoplasty balloon catheter with a maximum inflation volume of 6 cc and constrained burst pressure of at least 400 PSI. Its two radiopaque markers are spaced 15 mm apart. The model information also specifies EO sterilization and single-use status. For a buyer, this combination makes length, volume, marker spacing, and sterile single-use status the most directly checkable points in a model-level review.

The product information identifies KB0115 with orthopedic surgery and pain management or interventional pain clinic scenarios. The broader product description also places it in the Balloon Kyphoplasty (PKP) Products category. These descriptions indicate intended-use settings in the supplied materials; they do not replace the model’s labeling or local clinical protocols.

KB0120: a longer stated length with four-wing TPU pleating

KB0120 is listed at 315 mm, with a 6 cc maximum inflation volume and constrained burst pressure of at least 400 PSI. Its specified construction feature is four-wing TPU pleating. The supplied scenario information names orthopedic surgery, spine surgery, pain management, and interventional pain clinics.

Compared with KB0115, the stated distinction is not the inflation volume or the minimum constrained burst pressure; both are listed as 6 cc and at least 400 PSI. The listed differences are length and the KB0120 four-wing TPU pleating detail. Buyers who need to distinguish these models should make those differences explicit in their technical review and purchase-order description. The information provided does not give KB0120 marker spacing, so it should not be assumed to match KB0115’s 15 mm spacing.

KB0120S1: the 11G, 3 cc specification

KB0120S1 is identified as an 11G model with a 3 cc maximum inflation volume and constrained burst pressure of at least 400 PSI. The supplied information does not provide a length or marker-spacing value for this model. Those omissions matter during execution: a buyer requiring one of these details should confirm it from the current product specification before approval rather than borrowing the value from KB0210S1 or another catheter.

KB0210S1: an 11G model with stated length and marker spacing

KB0210S1 is also identified as an 11G, 3 cc model. Its supplied model details add a length of 280 mm and radiopaque marker spacing of 10 mm. The scenario information identifies spine surgery, pain management, and interventional pain clinics. For procurement comparison with KB0120S1, the confirmed common details are gauge, volume, and minimum constrained burst pressure; the stated additional KB0210S1 details are length and marker spacing. No claim about an unlisted KB0120S1 dimension or marker interval should be inferred from this comparison.

Matching the shortlist to buyer and care-setting requirements

Model specifications help organize a shortlist, but they do not establish a one-to-one match between a catheter and a clinical department. The supplied intended-use descriptions associate KB0115 with orthopedic surgery and pain management or interventional pain clinics; KB0120 with orthopedic surgery, spine surgery, pain management, and interventional pain clinics; and KB0210S1 with spine surgery, pain management, and interventional pain clinics. The available scenario statement for KB0120S1 specifies its 11G, 3 cc, and pressure details but does not provide a separate department list.

For a hospital, a practical review can begin by checking whether the model’s documented intended use and configuration align with the department’s requirements and local procedures. For a distributor, the same information can help separate product variants in a catalog, quotation, or stock plan. Neither use supports claims that one model is clinically better, appropriate for a particular patient, or interchangeable with another model.

• If the requirement specifies 6 cc: compare KB0115 and KB0120 using their listed lengths and model-specific features.
• If the requirement specifies 11G and 3 cc: compare KB0120S1 and KB0210S1, then verify whether the stated 280 mm length and 10 mm marker spacing of KB0210S1 are required.
• If marker spacing is a purchasing criterion: the supplied values are 15 mm for KB0115 and 10 mm for KB0210S1. No value is provided here for KB0120 or KB0120S1.
• If length is a purchasing criterion: the supplied values are 280 mm for KB0115, 315 mm for KB0120, and 280 mm for KB0210S1. KB0120S1 length is not stated in the information used for this article.

System components and documentation boundaries

A kyphoplasty system may be evaluated as a set of components rather than as a catheter alone. In the supplied product information, the KT-00-05 Kyphoplasty Tool Kit is listed with CE 0123 protection level. This statement should be read as the supplied designation for that kit, not as a claim that every listed catheter or every system component shares the same certification scope. Buyers should check the product-specific documentation and the applicable market requirements for the exact items being purchased.

The balloon inflator is a system component to consider in the equipment and procurement review. The information available for this article does not establish a specific compatibility pairing between the inflator and each of the four catheter models above, nor does it support additional claims about inflator performance. Confirm component compatibility and configuration in the manufacturer’s current documentation before placing an order.

More generally, the product materials identify the kyphoplasty balloon catheter as a device used in percutaneous balloon kyphoplasty (PKP) procedures. The KB0115 product information describes medical-grade thermoplastic polyurethane, a PU shaft, radiopaque markers, and a stainless-steel stylet. These details are specific to the cited KB0115 description and should not be generalized to every model without model-specific confirmation.

A practical evaluation-to-execution checklist

Before converting a shortlist into an order, buyers can use a simple verification sequence. It is designed to reduce ambiguity in model identification; it is not a clinical decision protocol.

1. Record the exact model code. Keep KB0115, KB0120, KB0120S1, and KB0210S1 distinct in the request, quotation, and order documents.
2. Specify only confirmed attributes. Record gauge, length, inflation volume, burst pressure, marker spacing, pleating, and sterilization status only where the information is available for that model.
3. Resolve missing fields before approval. If a required detail is not stated in the information at hand—such as KB0120S1 length—request and review the current model-specific documentation.
4. Confirm intended use and local requirements. Review the current labeling and IFU alongside the institution’s requirements and the rules applicable in the destination market.
5. Check the full system configuration. Confirm the required tool kit and balloon inflator configuration from product documentation. Do not assume compatibility based only on a shared product category.
6. Align purchasing records with the approved configuration. Make sure model codes and accepted specifications appear consistently in the quotation, purchase order, and receiving checks.

What this shortlist can—and cannot—tell buyers

The shortlist can narrow a product review by showing which supplied model details are different and which questions remain open. It cannot determine patient selection, establish clinical outcomes, replace an IFU, or prove that a component is compatible with another component. A model’s stated pressure, inflation volume, gauge, length, or marker spacing is a specification—not, by itself, evidence of a clinical result.

There is also a trade-off between standardizing on one model and maintaining options. A single-SKU approach can simplify catalog and inventory administration, but it may not satisfy requirements that specify different gauges, lengths, or marker spacing. A multi-model shortlist offers more specification choices, while requiring clearer item identification, documentation control, and stock planning. The appropriate purchasing approach depends on the buyer’s verified requirements; the supplied data do not establish a universally preferred model.

Procurement takeaway

For buyers evaluating CHANGMEI Kyphoplasty, the clearest dividing line in this shortlist is between the 6 cc KB0115 and KB0120 models and the 11G, 3 cc KB0120S1 and KB0210S1 models. The supplied details further distinguish KB0115 by its 280 mm length, 15 mm marker spacing, and EO-sterilized single-use status; KB0120 by its 315 mm length and four-wing TPU pleating; and KB0210S1 by its 280 mm length and 10 mm marker spacing. KB0120S1 is specified here as 11G, 3 cc, and ≥400 PSI, with length and marker spacing left for model-specific confirmation.

For execution, buyers should convert the preferred specification into an exact model code, verify all required details against current product documentation, and confirm the tool kit and balloon inflator configuration separately. The KT-00-05 tool kit is identified in the supplied information with CE 0123 protection level; that designation should not be expanded beyond its documented scope.
