## Indications for Use

The Twin-Pass Torque catheter is intended to access discrete regions of the coronary and/or peripheral vasculature. It may be used to facilitate placement and exchange of guidewires and to subselectively infuse/deliver diagnostic and therapeutic agents.

## Device Story

Twin-Pass Torque is a dual-lumen percutaneous catheter; features over-the-wire (OTW) lumen and rapid exchange (RX) delivery lumen. Used by physicians in coronary/peripheral vascular procedures to access specific regions, facilitate guidewire exchange, and deliver diagnostic/therapeutic agents. Device includes radiopaque platinum-iridium marker bands for visualization and positioning marks on shaft. Operates via manual manipulation by clinician under fluoroscopic guidance. Benefits include improved access and guidewire management in complex vascular anatomy.

## Clinical Evidence

Bench testing only. Verification testing included kink resistance, guidewire insertion, tip/shaft flexibility, torque control/strength/transmission, tensile strength, hub luer tests, and coating lubricity/particulate. Biocompatibility testing per ISO 10993-1 included cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, and hemocompatibility. All tests met acceptance criteria.

## Technological Characteristics

Dual-lumen percutaneous catheter; OTW and RX lumens. Materials include platinum-iridium marker bands. Features hydrophilic coating. Manual operation; no energy source. Sterilization method not specified. Design includes radiopaque markers and positioning marks.

## Regulatory Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

Dear Ms. Gallatin:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices. good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

### Device Description

The Twin-Pass Torque is a dual lumen catheter consisting of an over-the-wire (OTW) lumen that runs the full length of the catheter, exiting just proximal to the distal tip, and a rapid exchange (RX) delivery lumen on the distal segment. The two exit ports are each marked by a radiopaque platinum-iridium marker band and the device shaft has two positioning marks located at 95cm (single mark) and 105cm (double marks) from the distal tip, which are not visible under fluoroscopy.

# Intended Use

The Twin-Pass Torque catheter is intended to access discrete regions of the coronary and/or peripheral vasculature. It may be used to facilitate placement and exchange of guidewires and to subselectively infuse/deliver diagnostic and therapeutic agents.

# Technological Characteristics Comparison

Twin-Pass Torque is similar in design to the predicate device and both are dual lumen, percutaneous catheters intended to access discrete regions of the coronary and peripheral vasculature, facilitate placement and exchange of guidewires and subselectively infuse agents. With the exception of dimensional, material and package configuration differences, the Twin-Pass Torque is similar in design and technological characteristics to the predicate device. The dimensional, material and package configuration differences were successfully evaluated in performance tests.

{4}------------------------------------------------

# Substantial Equivalence and Summary of Studies

The technological differences between the subject and predicate devices have been evaluated through performance and biocompatibility tests and results did not raise new questions of safety or effectiveness. The Twin-Pass dual access catheter is substantially equivalent to the specified predicate device based on comparisons of the device functionality, technological characteristics, and indications for use. The device design has been verified through the following tests:

- . Kink resistance
- . Guidewire insertion
- . Tip flexibility
- . Distal shaft flexibility
- Proximal shaft support ●
- Coating lubricity/Durability ●
- Radiopacity
- Guidewire deflection ●
- Distal tip length ●
- . Torque control
- Torque transmission ●
- Tensile strength .
- . Torque strength
- Torque robustness
- Hub luer tests (air leak, burst, compatibility)
- Hydrophilic coating particulate
- . Package integrity

Device samples passed the following biocompatibility tests performed in accordance with ISO 10993-1:

- . Cytotoxicity
- Sensitization
- . Irritation
- Systemic toxicity ●
- . Pyrogenicity
- . Hemocompatibility

The results of the verification tests met the specified acceptance criteria and did not raise new safety or performance issues. Therefore, the Twin-Pass Torque dual access catheter is substantially equivalent to the predicate device.
