Guidewire support system and guidewire
First Claim
1. A guidewire support system comprising a support catheter for insertion into a vascular system of a human or an animal, the support catheter bounding a lumen for receiving at least a portion of a guidewire, and comprising a guidewire engagement structure for allowing the support catheter to engage the guidewire inside the lumen, the engagement structure in engaged condition causing the guidewire and the support catheter to be held mutually positioned at least in longitudinal direction thereof, wherein the guidewire engagement structure includes:
- a support catheter wall portion sufficiently elastically deformable for transferring an externally applied clamping force at least partially to fix the guidewire in the lumen and to release the guidewire in response to releasing of the clamping force; and
a torque steering device arranged to be clamped to an outside surface portion of the support catheter and for exerting a clamping force to the support catheter causing said wall portions of the support catheter to be clamped against the guidewire in the lumen, wherein the support catheter extends through the torque steering device, the torque steering device is displaceable in the longitudinal direction along a section of the support catheter, between different positions at different distances in the longitudinal direction from the proximal end of the support catheter where a wall portion of the support catheter is clampable against the guidewire by the torque steering device for effecting the fixation of the guidewire in the lumen.

Abstract
A guidewire system for insertion into a vascular system of a human or an animal so as to form a guide for guiding a catheter to a predetermined position. The system comprises a support catheter bounding a lumen for receiving at least a portion of the guidewire. The support catheter comprises a guidewire engagement structure for engaging the guidewire inside the lumen. The engagement structure in engaged condition causes the guidewire and the support catheter to be held mutually positioned at least in longitudinal direction thereof.
