OFFSET COUPLING REGION
First Claim
1. A medical device deployment system comprising:
- an elongated guide member having a proximal end, a distal end, and a lumen at least partially therethrough;
a support segment attached near the distal end of the elongated guide member;
a medical device disposed adjacent to the support segment;
a containment element disposed about at least a portion of the medical device;
an actuation element having a proximal end and a distal end and a first position and a second position, wherein the distal end of the actuation element engages at least a portion of the containment element in the first position and is at least partially disengaged from the containment element in the second position; and
an offset coupling region between the guide member and the support segment, wherein the actuation element extends beyond the distal end of the guide member and generally coaxial with it to engage the containment element at one or more points in the first position.

Abstract
The invention provides a medical device delivery system comprising an offset coupling region interposed between an elongated hypotube guide member or catheter and a support segment. The medical device to be delivered is disposed about the support segment and contained and/or constrained within a containment element. The medical device may be released from the containment element by moving an actuation element from a first position to a second position. The offset coupling region allows the actuation element to exit a lumen within the guide member and to engage the containment element in the first position while traveling along a line generally coaxial with the lumen of the guide member.

25. A medical device deployment system comprising:
-
an elongated guide member having a proximal end, a distal end, and a lumen associated therewith; an offset coupling region attached to the distal end of the guide member; an actuation element having a proximal end, a distal end, a first position, and a second position; a support segment having a distal end and having a proximal end attached to the offset coupling region, wherein the guide member, the support segment and the actuation element are generally coplanar; a medical device disposed adjacent to the support segment; a containment element disposed about at least a portion of the medical device, wherein the distal end of the actuation element engages at least a portion of the containment element in the first position and is at least partially disengaged from the containment element in the second position; and wherein the actuation element extends beyond the distal end of the guide member and extends generally coaxial with respect to the guide member to engage the containment element at one or more points in the first position. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)

40. A method of deploying a medical device comprising:
-
providing an elongated guide member having a proximal end and a distal end; providing a support segment attached near the distal end of the elongated guide member; providing a medical device disposed adjacent to the support segment; providing a containment element disposed about at least a portion of the medical device; providing an actuation element having a proximal end and a distal end and a first position and a second position, wherein the distal end of the actuation element engages at least a portion of the containment element in the first position and is at least partially disengaged from the containment element in the second position; providing an offset coupling region between the guide member and the support segment, wherein the actuation element extends beyond the distal end of the guide member and generally coaxial with it to engage the containment element at one or more points in the first position; advancing the medical device to a desired deployment site; and moving the actuation element from a first position to a second position thereby releasing the medical device from the containment element.
