Device Story

Heraeus TMW Guidewire is a steerable, disposable, bi-metal core guidewire used to facilitate catheter placement during PTA/PTCA. Device features Triton Nitinol distal core, stainless steel proximal core, hydrophilic coating, and 3 cm radiopaque distal tip. Operated manually by clinicians in clinical settings. Provides mechanical support and guidance for interventional devices; aids in navigating vasculature. Benefits include precise catheter delivery and procedural support. No software or automated processing involved.

Clinical Evidence

Bench testing only. No clinical data. Testing included biocompatibility (ISO 10993-1), particulate testing, corrosion resistance, dimensional inspection, sterilization validation, package integrity, tensile strength, tip stiffness, torque response, and radiopacity. All tests met predetermined acceptance criteria.

Technological Characteristics

- Performance Testing: In vitro bench tests were utilized to demonstrate equivalence with reference to the FDAs guidance document "Coronary and Cerebrovascular Guidewire Guidance, Jan 1995".
The performance testing assessment supports that the biocompatibility, shelf life, and functional specifications of the proposed Guidewire device were met.

The Heraeus TMW Guidewire device test data supports the claims of substantial equivalence to the predicate devices. Biological Safety of the predicate device has been established through biocompatibility testing carried out in compliance with ISO10993-1:2009 and G95-1, FDA General Program Memorandum: Use of International Standard ISO-10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing.

The following bench tests were conducted or evaluated to support the proposed device:

- . biocompatibility testing (including: Cytotoxicity, Sensitization, Intracutaneous Reactivity, Acute Systemic Toxicity, Pyrogen Testing, Hemolysis, Complement Activation, In-Vivo Thrombogenicity)
- particulate testing ●
- corrosion resistance
- dimensional inspection ●
- sterilization ●
- sterile package integrity testing
- tensile strength ●
- tip stiffness ●
- torque response ●
- corrosion resistance ●
- . radiopacity
- . tip stiffness

The Heraeus TMW Guidewire System met all predetermined acceptance criteria and compared favorably with the predicate device.

#### Conclusion: Heraeus considers the Heraeus TMW Guidewire to be equivalent to the predicate device. This conclusion is based upon the fact that device has an equivalent intended use, and there are no differences that raise new types of questions of safety and effectiveness.
