Systems and methods for positioning and compacting a bodily implant

摘要

Bodily implants that can be compacted in a distal-to-proximal direction, and which facilitate repositioning of the implant after compaction. The implants include at least one pull string for expanding the implant in a radial direction while compacting the implant in the longitudinal direction. Where multiple pull strings are provided, they can be secured to the implant at spaced locations along the implant length, and pulled successively to compact the implant in a distal-to-proximal direction. A guide member may also be provided to receive the pull strings and facilitate longitudinal compaction.

1. A medical treatment system, comprising:
an elongate, flexible, tubular pushrod, the pushrod having a distal end; a guide member coupled adjacent the distal end of the pushrod; an implant coupled adjacent the distal end of the pushrod and proximal of the guide member and extending proximally along the pushrod, the implant having a proximal portion adjacent a proximal end and a distal portion adjacent a distal end, the implant comprising a plurality of bioabsorbable fibers; a distal pull string extending through the guide member and secured to the implant at a first attachment point within the distal portion of the implant; and a proximal pull string extending through the guide member and secured to the implant at a second attachment point within the proximal portion of the implant, wherein pulling the distal string in a proximal direction compacts at least a portion of the distal portion of the implant in a distal direction and pulling the proximal pull string in a proximal direction compacts at least a portion of the proximal portion of the implant in a distal direction.
