Delivery system for vascular implant
First Claim
1. A method of delivering a medical implant, comprising:
- providing an implant delivery system comprising a self expanding implant configured to longitudinally foreshorten upon radially expanding from a compacted radial state, a delivery device comprising proximal and distal mounts that selectively connect to the implant through flexible proximal and distal intermediate components by a proximal and a distal interface, respectively, the delivery device configured so that the proximal and distal mounts can be selectively moved relative to one another so as to selectively apply a longitudinal tension on the implant through the proximal and distal intermediate components to urge the implant into the compacted radial state;
advancing the implant in a compacted radial state within a patient to a desired deployment location;
positioning the implant adjacent the desired deployment location;
actuating the delivery device so as to move the proximal and distal mounts toward one another so as to reduce the longitudinal tension on the implant and allow the implant to radially expand toward a fully expanded state;
verifying the implant is properly positioned at the desired deployment location within the patient.

Abstract
A medical treatment system and method of treatment is described having an implant that can be positioned and deployed, then undeployed to allow repositioning of the implant. The system includes a self-expanding medical implant that longitudinally foreshortens upon radially expanding from a radially compacted state, a distal interface configured to attach the implant to a distal mount of a delivery device, and a proximal interface configured to attach the implant to a proximal mount of the delivery device. Moving the distal mount longitudinally away from the proximal mount applies a longitudinal tension to the implant causing the implant to expand longitudinally and contract radially, and moving the distal mount toward the proximal mount reduces a longitudinal tension in the implant allowing the implant to expand radially toward a fully expanded state.
