The Boston Scientific PT2 MS Coronary Guidewire (REF H74938931042) is a percutaneous transluminal coronary angioplasty (PTCA) guidewire designed to facilitate the placement and exchange of interventional devices within the coronary vasculature. Engineered as part of the PT2 family, the MS (Moderate Support) configuration is intended to balance trackability, torque response, and shapeability for day-to-day interventional workflows.

Key Features
- Moderate support (MS) core designed to balance pushability with vessel conformability.
- Hydrophilic polymer coating on the distal segment to support smooth advancement through tortuous anatomy.
- PTFE coating on the proximal shaft to reduce friction during device exchanges.
- Shapeable distal tip to accommodate operator preference and lesion morphology.
- 1:1 torque response intended to aid precise steering and vessel selection.
- Radiopaque distal segment for fluoroscopic visualization during navigation.

Clinical Applications
- Guidance and placement of interventional devices during percutaneous coronary intervention (PCI).
- Navigation of native coronary arteries and bypass grafts during diagnostic and therapeutic procedures.
- Facilitation of balloon catheter, stent, and microcatheter delivery and exchange.
- Routine workhorse wire selection for standard coronary lesion crossing.
