Abstract
Occlusive implants are provided with various embodiments of active and/or passive release structures. Systems for delivering the occlusive implants as well as methods for making and delivering the implants are also provided.
Claims27
A medical system, comprising:
- an occlusive implant having a distal end and a proximal end, the occlusive implant comprising a flexible body with a covering that comprises a plurality of fibers in the form of a braid, wherein at least one fiber of the plurality of fibers extends from the covering in the form of a loop at the proximal end of the occlusive implant;
- an elongate tubular member having an inner lumen;
- and
- an elongate pusher member slidable within the inner lumen and having a distal end region with a recess adapted to releasably hold the at least one fiber in the form of the loop.

A method of delivering an occlusive implant, comprising:
- positioning an open distal end of an elongate tubular member in proximity to a target delivery site, wherein a pusher member is releasably secured to an occlusive implant within an inner lumen of the elongate tubular member;
- advancing the pusher member distally to push the occlusive implant from within the inner lumen, the occlusive implant having a distal end and a proximal end, the occlusive implant comprising a flexible body with a covering that comprises a plurality of fibers in the form of a braid, wherein at least one fiber of the plurality of fibers extends from the covering in the form of a loop at the proximal end of the occlusive implant;
- and
- withdrawing an elongate control wire proximally such that the occlusive implant is released from the pusher member after a distal terminus of the elongate control wire is withdrawn through the loop.
20-23. (canceled)
A medical system, comprising:
- an occlusive implant having a distal end and a proximal end, the occlusive implant comprising a flexible body with a covering that comprises a plurality of fibers in the form of a braid, wherein at least one fiber of the plurality of fibers extends proximally from the covering, the at least one fiber comprising a ball;
- an elongate tubular member having an inner lumen;
- and
- an elongate pusher member slidable within the inner lumen and having a distal end region with a recess adapted to releasably hold the ball when the ball and the recess are constrained within the inner lumen.

29-50. (canceled)
A method of delivering an occlusive implant comprising a distal end, a proximal end, and a flexible body with a covering that comprises a plurality of fibers in the form of a braid, wherein at least one fiber of the plurality of fibers extends proximally from the covering and comprises a ball, the method comprising:
- positioning an open distal end of an elongate tubular member in proximity to a target delivery site, wherein a distal end region of a pusher member is releasably secured to an occlusive implant within an inner lumen of the elongate tubular member;
- and
- causing relative movement between the pusher member and the elongate tubular member such that the proximal end of the occlusive implant and the distal end region of the pusher member are exposed from within the inner lumen, and the ball releases from within a recess in the distal end region of the pusher member thereby releasing the occlusive implant from the pusher member.
