Coronary Guidewires

Guidewires are as critical as any tool in the interventional cardiology toolbox-without the right guidewire to access and deliver devices to a lesion, successful treatment through PCI is impossible. The right guidewire can lead to improved outcomes, reduced procedure times, and increased procedural throughput.

SENTAITM Guidewire Family

Boston Scientific collaborated closely with Japan-based Future Medical Design (FMD) Co. Ltd. in the development of its line of SENTAI coronary guidewires.  FMD is a leading design and manufacturing firm for interventional guidewire technology, and the exclusive global supplier of the SENTAI family of wires, which includes two frontline workhorse wires, seven specialty crossing wires, and an extension wire.

To safely navigate even the most challenging anatomy and access hard-to-reach lesions.

To enable you to cross, and ultimately treat, even the most challenging and resistant lesions.

To enable treatment of multi-vessel cases with one wire, saving the time and expense of using additional wires.

Rail Support
For successful device delivery without the need for buddy wires or wire exchanges.

Inner Coil Technology

The advanced design of the stainless steel core and Inner Coil Technology provides a unique combination of exceptional torqueability, rail support, and shape retention.

  • Stainless steel inner coil affixed directly to the distal end of the guidewire core
  • Improved durability and ease of shaping
  • Exceptional torqueability without whipping

Micro EMTTM Technology

MICRO EMT exactly matches the taper of the core and coil, allowing for a lower profile and a more flexible core, leaving almost no room for the core to move within the coil, resulting in 1:1 torque.

  • Entry: The smallest tip on the market (0.008”) and the long taper (6 cm) facilitate easy lesion entry in even the most complex lesions.
  • Maneuverability: A flexible distal shaft enables excellent intraluminal navigation in complex lesions, with minimal perforation risk.
  • Torque: With exactly matched tapers, the core and coil move as one, eliminating whip and empowering precise steerability.
