Abstract
This present disclosure relates to steerable catheters comprising first and second steering sections that are respectively configured to steer in opposite directions within the same plane. The present disclosure also relates to a system comprising a steerable catheter according to the present disclosure and a patch deployment device that is deployable via the catheter.
Claims30
A steerable catheter comprising a longitudinal tube having a proximal end, a distal end comprising a distal opening and an internal lumen extending to the distal opening;
- wherein a steering zone is provided adjacent to the distal end, wherein the steering zone comprises:
- a first steering section;
- and
- a second steering section, disposed proximally of the first steering section along a longitudinal axis of the steerable catheter;
- wherein the first steering section is independently actuatable to steer in a first direction in a first plane, wherein the first plane is parallel to and intersects the longitudinal axis of the steerable catheter;
- wherein the second steering section is independently actuatable to steer in a second direction, wherein the second direction is opposite to the first direction;
- and
- wherein the steering zone is configured such that when the second steering section is actuated to its maximum steering angle, the distal end cannot intersect a second plane, wherein the second plane is parallel to and intersects the longitudinal axis of the steerable catheter and is perpendicular to the first plane.
A steerable catheter comprising a longitudinal tube having a proximal end, a distal end comprising a distal opening, and an internal lumen extending to the distal opening;
- wherein a steering zone is provided adjacent to the distal end, wherein the steering zone comprises:
- a first steering section, wherein the first steering section is independently actuatable to steer in a first direction in a first plane, wherein the first plane is parallel to and intersects a longitudinal axis of the steerable catheter;
- and
- a shape-set curve steering section, disposed proximally of the first steering section along the longitudinal axis of the steerable catheter, wherein the shape-set curve steering section is curved in a second direction and is independently actuatable to steer in the first direction, wherein the second direction is opposite to the first direction;
- and
- wherein the steering zone is configured such that when the shape-set curve steering section is not actuated, the distal end of the steerable catheter cannot intersect a second plane, wherein the second plane is parallel to and intersects the longitudinal axis of the steerable catheter and is perpendicular to the first plane.
