LOW PROFILE, MULTI-CONDUCTOR GUIDEWIRE

摘要

This invention relates to medical guidewire having multiple electrically conductive pathways extending from substantially their distal ends to substantially their proximal ends.

主权项

1. A guidewire for intravascular measurement of at least four variables comprising:
an elongate guidewire body having a distal segment and a proximal segment and having a diameter and defining a guidewire body surface and guidewire body bulk; the guidewire body surface defining at least one helical groove extending along the length of the guidewire body between its distal segment and its proximal segment, the helical groove extending into the guidewire body bulk; a sensor region on the distal segment of the guidewire body, the sensor region having at least four sensor elements; at least four connectors on the proximal segment of the guidewire body; at least four cables coupling the connectors to the sensor elements, the cables being located within the helical groove(s) defined by the guidewire body and not projecting outside the diameter of the guidewire body.
