Intended Use

The BridgePoint Medical Stingray™ Guidewires are intended to facilitate placement of balloon dilatation catheters or other intravascular devices during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The Stingray™ Guidewires are not to be used in the cerebral blood vessels. When used as part of the BridgePoint Medical System (consisting of the CrossBoss™ Catheter, Stingray™ Catheter, and Stingray™ Guidewire), the Stingray™ Guidewire is indicated for use to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions [CTOs]) prior to PTCA or stent intervention.

Device Story

Single-use, disposable percutaneous guidewire; stainless steel core shaft with distal taper for flexibility; platinum/tungsten distal coil for fluoroscopic visibility; hydrophilic coating. Used in clinical settings (e.g., cath lab) by physicians to facilitate placement of balloon dilatation catheters or other intravascular devices during PTCA/PTA. When used with the BridgePoint Medical System (CrossBoss/Stingray catheters), it assists in navigating beyond stenotic coronary lesions or chronic total occlusions. Provides mechanical support and guidance for interventional tools; enables precise placement via radiopaque tip visualization under fluoroscopy. Benefits include improved procedural success in complex coronary interventions.

Clinical Evidence

Bench testing only. No clinical data or in vivo testing performed. Bench tests included tensile, dimensional, insertion/withdrawal, flexibility, fatigue, coating, torque, surface defects, tip memory, and corrosion. Biocompatibility testing included cytotoxicity, sensitization, irritation, systemic toxicity, pyrogenicity, hemocompatibility, complement activation, and thrombogenicity. All results met established performance criteria.

Technological Characteristics

Single-use guidewire; 302 stainless steel core; proximal PTFE coating with cobalt titanate green colorant; distal platinum/tungsten coil (0.0020" diameter); hydrophilic coating; angled distal tip geometry. Radiopaque for fluoroscopic visualization. Mechanical device; no energy source or software.

Indications for Use

Indicated for patients undergoing PTCA or PTA procedures requiring intravascular device placement. Used to facilitate intraluminal placement of guidewires beyond stenotic coronary lesions, including chronic total occlusions (CTOs). Contraindicated for use in cerebral blood vessels.

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

*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

#### Device Description:

The modified Stingray™ Guidewires are conventionally constructed, single use. disposable guidewires that consist of a full-length stainless steel shaft with proximal PTFE coating where the distal portion of the stainless steel core is taper ground to provide distal flexibility. The distal portion also includes a coaxially positioned coil constructed of platinum/tungsten material for visibility under fluoroscopy. The coil is fixed to the stainless steel core wire via silver alloy solder and is hydrophilic coated. The distal tip of the guidewire is supplied with an angled geometry which transitions to a conventional rounded tip. A short extension with an approximate diameter of 0.0035" (which is a monolithic extension of the core wire) extends approximately 0.007" distal of the rounded tip.

#### Intended Use:

The BridgePoint Medical Stingray™ Guidewires are intended to facilitate placement of balloon dilatation catheters or other intravascular devices during percutaneous transluminal coronary angiography (PTCA) and percutaneous transluminal angiography (PTA). The Stingray™ Guidewires are not to be used in cerebral blood vessels.

When used as part of the BridgePoint Medical System (consisting of the CrossBoss™ Catheter, Stingray™ Catheter, and Stingray™ Guidewire), the Stingray™ Guidewire is indicated for use to facilitate the intraluminal placement of conventional guidewires beyond stenotic coronary lesions (including chronic total occlusions [CTOs]) prior to PTCA or stent intervention.

#### Comparison to Predicate Device(s):

The modified Stingray™ Guidewires are substantially equivalent to the previously cleared Stingray™ Guidewires. K081187 and K083727. in that they are all designed to facilitate placement of balloon dilatation catheters or other intravascular devices during PTCA and PTA procedures.

The Stingray™ Guidewires and previously cleared Stingray™ Guidewires are manufactured using the same processes and components and have similar physical attributes (flexibility, radiopacity, lubricity, tensile, torque, etc.). The distal tips of each device are radiopaque and can be seen with fluoroscopy for precise placement. All devices are highly lubricious for smooth delivery of multiple devices.

The modifications made to the originally cleared Stingray™ Guidewires include changes in the core wire material, colorant compound used in the proximal PTFE coating, and platinum tungsten coil diameter of the hydrophilic guidewires only (models M-3004 and M-3012). The core wire material is being modified from 304 stainless steel to 302 stainless steel. The PTFE colorant is being modified from chromium oxide green (CAS i 308-38-9) to cobalt titanate green (CAS 68186-85-6). Both of the new materials (core wire and proximal coating colorant) are currently used on other legally marketed devices within the same classification regulation for the same intended use. The distal platinum tungsten coil diameter is being modified from 0.0025" to 0.0020".

#### Performance Data:

The modified Stingray™ Guidewires have been evaluated using the following in vitro bench testing to confirm the performance characteristics as compared to the predicate device:

- Tensile .
- Dimensional .
- Guidewire Insert & Withdrawal
- Flexibility .
- Fatigue .
- Coating
- Torque
- Surface Defects
- Tip Memory, and
- Corrosion

In vivo testing was not deemed necessary based on the significance of the proposed modifications to the baseline device. The modified proximal coating formulation, core wire material, and distal coil dimensions result in a device that meets the original design requirements of the currently marketed Stingray™ Guidewires as demonstrated in the bench tests above. Animal studies were successfully completed with the currently marketed Stingray™ Guidewires.

Biocompatibility tests were completed to ensure all materials utilized to construct the modified Stingray™ Guidewires were biocompatibility tests included:

- Cytotoxicity .
- . Kligman Sensitization
- Irritation .
- Acute Systemic Cytotoxicity .
- Pryogen .
- Hemocompatibility
- In Vitro Hemocompatibility t
- . Complement Activation Assay (Direct)
- In Vivo Thrombogenicity, and .
- Unactivated Partial Thromboplastin Time.

All results demonstrated the materials, manufacturing processes, and design of the modified Stingray™ Guidewires met the established performance criteria and will perform as intended.

#### Summary:

Based upon the intended use and descriptive information provided in this pre-market notification, the modifications to the BridgePoint Stingray™ Guidewires have been shown to be substantially equivalent to the currently marketed predicate device.
