Abstract
This invention relates to medical guidewire having multiple electrically conductive pathways extending from substantially their distal ends to substantially their proximal ends.
Claims13
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.

A guidewire for intravascular measurement of at least four variables consisting essentially of:
- an elongate guidewire core wire, the core wire having a distal segment and a proximal segment, a diameter and defining a core wire surface and core wire bulk;
- the core wire surface defining at least one helical groove extending along the length of the core wire between its distal segment and its proximal segment, the helical groove extending to the core wire bulk;
- a sensor region on the distal segment of the core wire, the sensor region having at least four sensor elements;
- at least four connectors located on the proximal segment of the core wire;
- at least four cables coupling the connectors to the sensor elements, the cables being located within the helical groove and not projecting outside the diameter of the core wire.
