Abstract
An occlusive implant can be delivered into a body vessel using a delivery assembly that can engage with at least a portion of the implant. The assembly can utilize an engagement member and an engagement socket or a catheter or sheath to removably couple the engagement member with the implant. When the implant is advanced to a target location in the body vessel, the implant can be released to restrict flow of a fluid through the vessel and/or promote occlusion of the vessel.
Claims20
An assembly for delivering an implant into a body vessel, the implant having a proximal coupling member, the assembly comprising:
- a sheath comprising a lumen, an inner surface, and a distal end;
- and
- an engagement member extending within the sheath lumen, the engagement member comprising a distal end portion having a socket extending from an outer surface of the distal end portion into the engagement member, the socket having an inner profile greater than an outer profile of the implant proximal coupling member to permit the implant proximal coupling member to be removably positionable within the socket,
- wherein in an engaged position, the socket is positioned proximal to the sheath distal end to permit the sheath inner surface and the socket to collectively restrict longitudinal movement of the implant proximal coupling member out of the socket, and wherein in a released position, the socket is positioned distal to the sheath distal end to permit the implant proximal coupling member to exit the socket.
An assembly for delivering an implant into a body vessel, the implant having a proximal coupling member, the assembly comprising:
- a sheath comprising a lumen, an inner surface, a distal end, and a longitudinal axis;
- and
- a core member extending longitudinally within the sheath lumen, the core member comprising a pusher member and at least one engagement arm extending distally of the pusher member, the engagement arm comprising a protrusion extending radially inwardly toward the longitudinal axis when the core member is positioned within the sheath lumen, the engagement arm having an engaged position in which the protrusion is spaced at a first distance from the longitudinal axis and a disengaged position in which the protrusion is spaced at a second distance from the longitudinal axis, the second distance being greater than the first distance.
An assembly for delivering an implant into a body vessel, the assembly comprising:
- a first slidable member comprising proximal and distal ends, the first slidable member being operably coupled to a pusher component, the first slidable member comprising an outer surface and a groove along the outer surface;
- a second slidable member comprising proximal and distal ends and a tubular component having a lumen through which the pusher component is disposed, the second slidable member being operably coupled to a sheath;
- and
- a release pin comprising a tab and an engagement portion, the engagement portion being removably couplable to the groove of the first slidable member to maintain a spacing between distal ends of the first slidable member and the second slidable member, the release pin being movable to permit the distal end of the first slidable member to be advanced distally toward the distal end of the second slidable member to facilitate release of the implant from the assembly.
