Claim 9:
10. A method of delivering implants at multiple different treatment sites within a subject, the method comprising:
advancing a delivery catheter to a first treatment site within the subject, wherein the delivery catheter comprises an inner shaft and an outer sheath concentrically surrounding the inner shaft, wherein the inner shaft and the outer sheath are configured to move relative to each other, a deployment actuator configured to cause the movement of the outer sheath relative to the inner shaft, and wherein the inner shaft is loaded with a plurality of implants at spaced-apart locations along the length of the inner shaft;
wherein the deployment actuator comprises a thumbwheel extending out of an upper surface of a main housing of a rotary deployment handle, the thumbwheel comprising a plurality of teeth configured to engage with links of a belt that is operatively coupled to the outer sheath so as to effect movement of the outer sheath relative to the inner shaft when the thumbwheel is rotated;
deploying a first implant of the plurality of implants at the first treatment site within the subject by un-sheathing the first implant of the plurality of implants by moving the outer sheath proximally while the inner shaft remains stationary, re-sheathing a portion of the inner shaft corresponding to the locations of the deployed first implant of the plurality of implants by moving the inner shaft proximally while the outer sheath remains stationary, thereby facilitating improved safety to the subject while the delivery catheter is moved to a second treatment site within the subject, wherein said re-sheathing is effected by an operator pulling a re-sheath assembly of the rotary deployment handle in a proximal direction;
wherein the re-sheath assembly comprises a re-sheath housing removably coupled to the proximal end of the main housing of the rotary deployment handle, a re-sheath button located adjacent the proximal end of the main housing distal to the re-sheath housing, and a re-sheath rack located within the main housing of the rotary deployment handle, wherein a proximal end of the re-sheath rack is fixedly coupled to the re-sheath housing; wherein movement of the re-sheath rack in the proximal direction during re-sheathing causes the thumbwheel to transition in a locked configuration such that rotation of the thumbwheel is prevented during re-sheathing;
advancing the delivery catheter to the second treatment site within the subject;
un-sheathing the portion of the inner shaft corresponding to the locations of the deployed first implant of the plurality of implants by moving the inner shaft distally while the outer sheath remains stationary such that a distal end of the outer sheath is at the same distance away from a distal end of the inner shaft as it was after deployment of the first implant of the plurality of implants, wherein said un-sheathing, of the portion of the inner shaft after delivery catheter is advanced to the second treatment site, is effected by the operator pushing the re-sheath housing of the rotary deployment handle in a distal direction; and
deploying a second implant of the plurality of implants at the second treatment site within the subject by un-sheathing the second implant of the plurality of implants by moving the outer sheath proximally while the inner shaft remains stationary.
