The Vector " Thi PTA Balloon Dilatation Catheter is recommended for Percutaneous Transluminal Angioplasty (PTA) of the femoral, iliac, popliteal, and renal arteries and for the treatment of obstructive lesions of native or synthetic arterio-venous dialysis fistulae.

The Vector Catheter is not indicated for use in the coronary arteries or for placement of or post dilatation of stents

Device Description

The Vector" PTA Catheter is a high pressure, non-compliant balloon catheter with a radiopaque coating on the balloon. The radio-opaque coating on the working length of the balloon minimizes or eliminates the need for using contrast solution to inflate the balloon. The radioopaque coating delineates the working length of the balloon and provides continuous fluoroscopic visibility during balloon placement. Saline may be used to inflate the balloon without affecting visualization. Contrast mixture may be used at the discretion of the physician.

The Vector4™ PTA Balloon Dilatation Catheter is a coaxial dual lumen over-the-wire balloon dilatation catheter. The central lumen accommodates guide wires up to 0.035 inches in diameter while the outer lumen is the inflation lumen for the balloon. The catheter includes an atraumatic tip to ease advancement of the catheter to and through the stenosis. The distal tip is visible under fluoroscopy.

The balloon is a high pressure composite balloon with a radiopaque coating on the working length to help visualize placement within the lesion during both placement and inflation without the use of contrast. The balloon's rated burst pressure is 30 atm.

The catheter is supplied sterile and non-pyrogenic. Different balloon sizes (5 mm to 10 mm) and catheter lengths (50 to 135 cm) are available. The proximal end of the catheter contains a hub with two female luer locks.

The device is compatible with 6-7F introducers. The introducer compatibility for each device size is listed on the device label itself. The materials used in the construction are biocompatible and latex free.

Study Details

Sample size used for the test set and the data provenance:
- The document describes "preclinical testing" of the device. It doesn't specify a numerical sample size for the test set or the provenance of any data (e.g., country of origin). The testing seems to be laboratory-based rather than involving patient data. This is a common approach for 510(k) submissions where a device is demonstrated to be substantially equivalent to an existing predicate device based on its technical characteristics and performance, rather than clinical outcomes. The studies mentioned are focused on the device's physical and mechanical properties.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. The ground truth for this type of device performance testing is based on engineering specifications and validated test methods, not expert consensus on clinical data.
Adjudication method for the test set:
- Not applicable. As the testing is against engineering specifications, there wouldn't be an adjudication method in the context of clinical interpretation.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- Not applicable. This device is a medical catheter, not an AI-powered diagnostic or assistive tool for human readers. Therefore, an MRMC study related to AI assistance is irrelevant.
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is a physical medical device, not an algorithm.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The ground truth used for determining device performance was based on pre-defined physical and performance specifications for PTA catheters, industry standards (e.g., ISO 10993-1 for biocompatibility), and manufacturing requirements. For comparative aspects like radiopacity and particulates, the predicate device served as a benchmark for "similarity."
The sample size for the training set:
- Not applicable. This device is not an AI/ML model that requires a training set.
How the ground truth for the training set was established:
- Not applicable. As above, no training set is relevant for this device.

Summary of Study Approach:

The study described is a series of non-clinical, laboratory-based engineering and performance tests designed to demonstrate that the Vector™ PTA Balloon Dilatation Catheter meets its product specifications and industry standards. The submission relies heavily on direct comparative testing with a legally marketed predicate device (Bard Conquest PTA catheter) to establish substantial equivalence. Key areas of comparison include materials, construction, intended use, and critical performance characteristics like fluoroscopic visualization and mechanical integrity. The focus is on ensuring the new device performs equivalently or acceptably when compared to a device already deemed safe and effective.

Indications for Use/Intended Use

The Vector Catheter is not indicated for use in the coronary arteries or for placement of or post dilatation of stents

Device Description and Technological Characteristics

The Vector" PTA Catheter is a high pressure, non-compliant balloon catheter with a radiopaque coating on the balloon. The radio-opaque coating on the working length of the balloon

{1}------------------------------------------------

minimizes or eliminates the need for using contrast solution to inflate the balloon. The radioopaque coating delineates the working length of the balloon and provides continuous fluoroscopic visibility during balloon placement. Saline may be used to inflate the balloon without affecting visualization. Contrast mixture may be used at the discretion of the physician.

Performance Data

The Vector 4™ PTA Balloon Dilatation Catheter is tested and meets all its physical and performance specifications including:

Balloon rated burst pressure .
Balloon compliance ●
Critical dimension verifications .
Guidewire and introducer compatibility .
Fluoroscopic visualization .
. Inflation/deflation times
. Repeat inflation
Leak
Tensile
. Kink
. Torque
Corrosion ●
. Luer lock compatibility
Coating integrity .
Distribution ●

In addition, the device was tested for biocompatibility ISO 10993-1 for short duration contact with blood (<24 hour).

{2}------------------------------------------------

The device is sterilized by ethylene oxide to an SAL 10° level. These performances are similar to that described by the predicate device as these are standard tests for PTA catheters. In addition, direct comparative testing for radiopacity and particulates was conducted for both devices and results found to be similar.

After accelerated aging on devices, a subset of the original tests that may be affected by aging were repeated.

The preclinical testing showed that the device meets specifications before and after aging indicating that the device is as safe and effective as the predicate device.

Substantial Equivalence

The Vector" is substantially equivalent to the Conquest PTA catheter (K083657). They have similar intended use, and treat the same target population. Both devices are intended to treat peripheral arteries. The Vector4" is indicated for an additional artery - popliteal artery which is also a peripheral artery with similar sizes and access as the other peripheral arteries. The manner in accessing and treating lesions in all these arteries is similar. Therefore, this minor change in indication for use does not change the intended use of the device and does not raise new safety and effectiveness question.

Both devices employ a composite balloon construction to attain the high rated burst pressures. Both devices are over the wire catheters with coaxial lumens. Both devices are compatible with 0.035" wires and have similar construction and principles of operation. Both devices are used by the physician in a similar manner typical of all PTA balloon catheters. Both devices are sterilized with ethylene oxide with a sterility assurance of 10°.

Fluoroscopic visualization for the Conquest balloon is achieved by injecting contrast into the balloon of the Conquest catheter while the radiopaque coating on the Vector balloon allows visualization without contrast. This difference does not raise new safety and effectiveness questions as the visualization under fluoroscopy has been shown to be equivalent for both devices.

Conclusion

The non-clinical testing of the Vector" PTA Balloon Dilatation Catheter met all the product specifications, and all the required standards for sterility and biocompatibility. The Vector" and the predicate Conquest PTA catheters have similar intended use and technological characteristics and are therefore substantially equivalent. These tests showed that the Vector"™ PTA Balloon Dilatation Catheter is as safe and effective as the predicate device.
