Steerable Catheters
First Claim
1. A steerable catheter comprising:
- a flexible elongate shaft having a proximal end portion, a distal end portion and a cable lumen extending from the proximal end portion to the distal end portion, the cable lumen having an opening at the distal end portion;
a control cable having a first portion and a second portion, the first portion of the control cable fixed in position relative to the shaft and the second portion movable relative to the shaft, at least a portion of the second portion extendable through at least a portion of the cable lumen and extendable through the opening, the control cable having a first position wherein the at least portion of the second portion is axially extendable away from a wall of the shaft and a second position for delivery of the catheter; and
a handle operably connected to the control cable for moving the control cable from the second position to the first position.

Abstract
A steerable catheter and a method of steering a catheter are provided. The steerable catheter includes a flexible elongate shaft having a proximal end portion, a distal end portion and a cable lumen extending from the proximal end portion to the distal end portion. The steerable catheter includes a control cable having a first portion and a second portion, the first portion of the control cable fixed in position relative to the shaft and the second portion movable relative to the shaft and at least a portion of the second portion is extendable through at least a portion of the cable lumen and extendable through the opening. The control cable has a first position where the at least the portion of the second portion is axially extendable away from a wall of the shaft and a second position for delivery of the catheter.

12. A steerable catheter comprising:
-
a flexible elongate shaft having a proximal end portion, a distal end portion and a plurality of cable lumens extending from the proximal end portion to the distal end portion, each of the plurality of cable lumens having an opening at the distal end portion; a plurality of control cables, each of the plurality of control cables having a first portion and a second portion, the first portion fixed in position relative to the shaft and the second portion movable relative to the shaft, each of the second portions having at least a portion thereof extendable through one the plurality of cable lumens and out through the opening and axially away from a wall of the shaft in a first position; and a handle operably connected to the plurality of control cables to move one or more of the control cables from a second position to the first position. - View Dependent Claims (13, 14, 15, 16)

17. A method of steering a catheter, the method comprising:
-
moving a second portion of a first control cable from a second cable position to a first cable position and a first portion of the first control cable remains fixed in position in relation to a shaft of the catheter; extending at least a portion of the second portion through an opening in the shaft and axially away from a wall of the shaft; and contacting a surface with the portion of the second portion so that a distal portion of the shaft is moved from a first shaft position to a second shaft position. - View Dependent Claims (18, 19, 20)
