#### Device Description

The Pre-Formed Guidewire Extra Support guidewire is designed to facilitate device placement during TAVR procedures and has a unique pre-shaped spiral distal tip to ensure placement within the heart. The guidewire is intended for single use.

The guidewire has a 0.035" diameter and is 275cm in length. The guidewire composed of two primary components: a core, and a coil. Both components are made of stainless steel. The core

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

wire component is a piece of stainless-steel wire which is ground on the distal end to fit into the coil and provide flexibility. The proximal end of the core wire is coated with grev polytetrafluoroethylene (PTFE) coating. The coil component is fitted over the distal end of the core and is a stainless-steel coiled with green PTFE coating. The coil and core components are secured together using a weld on the distal and a glue joint at the proximal end of the coil, forming the guidewire. The pre-shaped distal end of the guidewire is available in three sizes (extra-small, small and large).

The Pre-Formed Extra Support guidewire is sterilized using ethylene oxide. There are no accessories packaged with the Pre-Formed Extra Support guidewire.

# Indications for Use

Pre-Formed Extra Support guidewire is intended to facilitate the introduction and placement of interventional devices within the chambers of the heart, including those used during transcatheter aortic valve procedures.

### Comparison of Technological Characteristics with the Predicate Devices

The Pre-Formed Extra Support has the same indication for use/intended use and principles of operation as the legally marketed Pre-Formed guidewire (K151244). In addition, the functional characteristics of the Pre-Formed Extra Support are substantially equivalent to the Pre-Formed guidewire, with similar materials, dimensions, and method of construction. The design modifications to the new device include differences in material used on the coating for the core, the proximal joint and the partial coil design on the distal end. Performance and safety testing have shown that these modifications have not raised any new questions of safety or efficacy and the device continues to meet its intended use.

# Performance Data (Animal)

The Pre-Formed Extra Support guidewire was evaluated in a porcine model in accordance with 21 CFR Part 58 for Good Laboratory Practice (GLP) for Non- Clinical Laboratory studies. The subject device Pre-Formed Extra Support guidewire shares the same intended use and fundamental scientific technology as the predicate and demonstrated all safety and performance objectives as the device performed equivalent to the predicate, Pre-Formed guidewire, and

{6}------------------------------------------------

demonstrated all Customer Requirement Specifications as measured by post procedure feedback forms.

Conclusion: The Pre-Formed Extra Support guidewire met all design input requirements based on the intended use and supports the conclusion that the Pre-Formed Extra Support does not raise new questions of safety and effectiveness. The results of these tests support a determination of substantial equivalence to the predicate device, the Pre-Formed Guidewire (K151244).
