The Abbott TREK OTW Coronary Dilatation Catheter (REF 1012405-12) is an over-the-wire percutaneous transluminal coronary angioplasty (PTCA) balloon catheter featuring a 2.5 mm diameter x 12 mm length semi-compliant balloon. The OTW configuration supports full-length guidewire control, selective wire exchange, and distal pressure or contrast injection through the guidewire lumen, making it a versatile workhorse option for routine and complex coronary interventions.

Key Features
- Semi-compliant balloon material engineered for predictable, controlled inflation across the working pressure range.
- Balloon dimensions: 2.5 mm nominal diameter x 12 mm working length.
- Over-the-wire (OTW) design compatible with 0.014" coronary guidewires along the full catheter length.
- Low-profile balloon folding intended to support crossing of tight or calcified lesions.
- Dual radiopaque markers for fluoroscopic balloon placement.
- Hydrophilic distal shaft coating to help reduce friction during navigation.
- Tapered atraumatic balloon tip to facilitate lesion entry.
- Nominal and rated burst pressures: Not specified in the located sources — refer to the current Abbott TREK OTW compliance chart and IFU.

Clinical Applications
- Balloon dilatation of stenotic coronary artery lesions in native vessels and saphenous vein bypass grafts.
- Pre-dilatation prior to coronary stent deployment.
- Post-dilatation to optimize stent apposition when clinically indicated.
- Procedures in which an over-the-wire platform is preferred, including wire exchanges, distal contrast injection, and navigation through tortuous or distal anatomy.
- Suitability for any specific patient, lesion type, or procedure must be determined by the treating physician in accordance with the current Instructions for Use.
