Abstract

This invention is directed to a medical device having a longitudinal axis, and including a handle and a catheter. The handle can include a body having a proximal end and a distal end, an actuator moveably coupled to the body, and a handle control member coupled to the actuator, wherein the actuator can be configured to move relative to the body to move the handle control member. The catheter can include a shaft having a proximal end and a distal end, wherein the proximal end of the shaft and the distal end of the body can be configured for releasable coupling. The catheter can also include a steering section located along the shaft and a catheter control member coupled to the steering section, wherein the catheter control member can be configured to move relative to the shaft to move the steering section relative to the longitudinal axis. The medical device can also include a securing member configured to move relative to at least one of the handle and the catheter to releasably couple the handle control member to the catheter control member.

First claim

What is claimed is:

1. A device comprising:
a handle body having a proximal end and a distal end, the handle body configured to releasably couple to a catheter;
a lumen at the distal end configured to receive at least a portion of the catheter; and
a securing member positioned at the distal end of the handle and movable relative to the handle body between at least a first position and a second position,
wherein the securing member includes a lock movable in a direction perpendicular to a longitudinal axis of the handle, and wherein the catheter includes a threaded ring at a proximal end of the catheter and configured to couple with threading on the securing member.

2. The device of claim 1 , wherein the securing member further includes a protrusion that partially extends into the lumen, and wherein the catheter further includes a slot configured to receive the protrusion.

3. The device of claim 1 , wherein the threaded ring is rotatably coupled to the proximal end of the catheter.

4. The device of claim 3 , wherein the catheter includes a catheter lumen and a protrusion extending partially into the catheter lumen, and
wherein the securing member includes a slot configured to receive the protrusion.

5. The device of claim 1 , wherein the securing member includes an indentation, and wherein a width of the indentation is configured to correspond to a dimension of an end of the lock.

6. The device of claim 1 , wherein the securing member includes an indentation in a proximal portion of the securing member, and wherein the handle further comprises a locking collar configured for lateral movement relative to the securing member to limit a longitudinal movement or a rotational movement of the securing member.

7. The device of claim 1 , wherein the handle further includes a handle control member movable relative to the handle body, and wherein a proximal end of the handle control member is coupled to the handle and a distal end of the handle control member includes an attachment member.

8. The device of claim 1 , further including an actuator movably coupled to the handle body.

9. A device comprising:
a handle including a lock, the lock configured to move in a direction perpendicular to a longitudinal axis of a medical device; and
a securing member including an indentation, wherein a width of the indentation of the securing member corresponds with a dimension of an end of the lock to limit longitudinal movement of the securing member,
wherein the securing device comprises a lumen extending therethrough having a stop between a proximal portion of the lumen and a distal portion of the lumen, wherein the stop has a diameter less than a diameter of the proximal portion of the lumen, wherein the securing member includes a key configured to be received in a groove in the medical device, and wherein the securing member includes a thread configured to be coupled to a threaded ring on the medical device.

10. The device of claim 9 , wherein the securing member includes a groove configured to receive a key on the medical device.

11. The device of claim 9 , further including a handle control member with an attachment member, and wherein the stop has a diameter less than a diameter of a retaining member extending over at least a portion of the handle control member.

12. A device comprising:
a handle having a proximal end and a distal end,
a handle attachment coupled to the distal end of the handle;
a catheter including a proximal end and a distal end, wherein the catheter includes a catheter attachment at the proximal end;
a securing member configured to move relative to at least one of the handle and the catheter to permit releasable coupling of the handle attachment to the catheter attachment;
at least one handle control movable relative to the handle, wherein a proximal end of the handle control is movably coupled to the handle, and wherein a distal end of the handle control includes the handle attachment; and
a retaining member extending over at least a portion of the handle control, wherein the securing member includes a lumen with a stop between a proximal portion of the lumen and a distal portion of the lumen, and wherein the stop has a diameter less than a diameter of the retaining member.

13. The device of claim 12 , wherein the handle includes a lock configured to move in a direction perpendicular to a longitudinal axis of the device, and
wherein the securing member includes at least one indentation configured to engage with the lock to limit longitudinal movement of the securing member.
