Catheter with integral steerable guidewire having linear to rotary movement
First Claim
Patent Images
1. A catheter and guidewire for use therewith comprising:
- the catheter having an elongate flexible shaft with proximal and distal ends and at least one lumen extending through the shaft;
a guidewire having proximal and distal ends and being received in the lumen of the catheter shaft, the guidewire being rotatable and movable lengthwise of the catheter shaft, the distal end of the guidewire protruding distally of the distal end of the catheter shaft;
each of the guidewire and catheter having cooperative elements engageable with each other to cause the guidewire to rotate with respect to the catheter when the guidewire is moved lengthwise of the catheter, said cooperative elements being disposed closer to the distal end of the catheter than to the proximal end of the catheter.

Abstract
A catheter with an integral steerable guidewire converts linear movement of the guidewire to rotational movement at the distal end of the guidewire. The catheter has a guidewire lumen to receive the guidewire. The catheter and guidewire are constructed so that the guidewire can be reciprocated and rotated with respect to the catheter. The guidewire and catheter cooperate in a manner so that when the guidewire is reciprocated axially with respect to the catheter, that axial movement of the guidewire is converted into rotational movement.

5. A catheter and guidewire for use therewith comprising:
-
the catheter having an elongate flexible shaft with proximal and distal ends and at least one lumen extending through the shaft; a guidewire having proximal and distal ends and being received in the lumen of the catheter shaft, the guidewire being rotatable and movable lengthwise of the catheter shaft, the distal end of the guidewire protruding distally of the distal end of the catheter shaft; each of the guidewire and catheter having cooperative means for converting linear movement of the guidewire to rotational movement when the guidewire is moved lengthwise of the catheter, said cooperative means being disposed closer to the distal end of the catheter than to the proximal end of the catheter.

15. A catheter and integral, non-removable guidewire for use therewith comprising:
-
the catheter having an elongate flexible shaft with proximal and distal ends and at least one lumen extending through the shaft; an integral guidewire inseparably carried by the catheter, the guidewire having proximal and distal ends and being received in the lumen of the catheter shaft, the guidewire being capable of limited lengthwise movement in the shaft and rotation movement in the shaft, the distal end of the guidewire protruding distally of the distal end of the catheter shaft; and means engageable between the catheter and the guidewire for converting linear movement of the guidewire to rotary motion. - View Dependent Claims (16)
