Intended Use

Boston Scientific Fighter™, Marvel™, and Samurai™ RC Guidewires are intended to facilitate the placement of balloon dilatation catheters or other interventional therapeutic devices during percutaneous transluminal coronary angioplasty (PTCA) or other intravascular interventional procedures. These guidewires are not intended for use in the cerebral vasculature. Attachment of the Stretch Extension Wire to a Boston Scientific extendable guidewire creates an extended guide wire that can be used to exchange out a percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal angioplasty (PTA) catheter without removing the original guide wire from the artery. When the exchange is complete, the Stretch Extension Wire can be detached and the original guide wire can be used in a conventional manner.

Device Story

Guidewires facilitate placement of interventional coronary devices (balloon catheters, stent delivery systems) during PTCA or intravascular procedures; Stretch Extension Wire allows for catheter exchange without removing the primary guidewire. Devices consist of stainless steel core wire with tapered distal end, proximal stainless steel coil, and distal platinum/nickel radiopaque coil for fluoroscopic visualization. Proximal end features PTFE coating; distal portion features hydrophilic coating. Used in clinical settings by physicians; output is physical guidance of interventional tools through vasculature. Benefits include streamlined catheter exchange and precise device delivery.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing including dimensional evaluation, tip flexibility, tensile strength, torque response, coating lubricity/durability, radiodetectability, and extensive biocompatibility testing (cytotoxicity, sensitization, hemocompatibility, thrombogenicity).

Technological Characteristics

Stainless steel core wire; platinum/nickel radiopaque distal coil; PTFE proximal coating; hydrophilic distal coating. 0.014-inch diameter; 190 cm and 300 cm lengths. Straight or J-tip configurations. Sterilized. No software or electronic components.

Indications for Use

Indicated for patients undergoing percutaneous transluminal coronary angioplasty (PTCA) or other intravascular interventional procedures requiring the placement of balloon dilatation catheters or interventional therapeutic devices. Contraindicated for use in the cerebral vasculature.

Regulatory Classification

Identification

A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.

Special Controls

Dear Nikki Wahlberg:

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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

## Device Description

The Fighter™, Marvel™, Samurai™, and Samurai™ RC Guidewires are designed to facilitate the placement of interventional coronary devices such as dilating balloon catheters, stent delivery systems and other coronary artery diagnostic or therapeutic devices. The guide wires are available in a nominal diameter of 0.014 inches and nominal lengths of 190 cm and 300 cm. The 190 cm quide wires are compatible exclusively with the Stretch Extension Wire which can extend the quide wire length allowing for exchange of Over-The-Wire systems. The guide wires are composed of a stainless steel core wire which tapers at the distal end. The tapered distal end of the quide wire is covered with a proximal stainless steel coil and a distal platinum/nickel radiopaque coil that allows for visualization while using fluoroscopy. The proximal end of the guide wire contains a polytetrafluoroethylene (PTFE) coating and the distal portion of the wire is coated with a hydrophilic coating. All wires are available in a straight tip configuration. The Marvel and Samurai wires are available in an additional J-tip configuration.

The Stretch Extension Wire is composed of a stainless steel core wire coated with PTFE and contains a hypotube that is compatible with the 190 cm Fighter, Marvel, Samurai, and Samurai RC Guidewires.
