Implant delivery system

Abstract

A delivery system used for vascular implant delivery is described. In some embodiments, the delivery system includes a user-gripped handle used to aid in retracting and advancing an implant. In some embodiments, the delivery system includes a telescoping pusher system to aid in retracting and advancing an implant.

What is claimed is: 
     
         1 . An implant delivery device, comprising:
 a housing including an aperture;   a delivery device extending through the housing;   a pusher extending through the delivery device; and   a sliding element movably connected to the housing, wherein the sliding element is connected to the delivery device through the aperture; and,   wherein moving the sliding element in a proximal direction retracts the delivery device and exposes the pusher.   
     
     
         2 . The implant delivery device of  claim 1 , wherein the aperture is comprised of a slot. 
     
     
         3 . The implant delivery device of  claim 2 , wherein the slot extends along at least half of a length of the housing. 
     
     
         4 . The implant delivery device of  claim 1 , wherein the delivery device is comprised of a catheter. 
     
     
         5 . The implant delivery device of  claim 1 , further comprising an engagement member through which the delivery device passes. 
     
     
         6 . The implant delivery device of  claim 5 , wherein the sliding element is attached to the engagement member. 
     
     
         7 . The implant delivery device of  claim 5 , wherein the engagement member is comprised of a distal element and a proximal element. 
     
     
         8 . The implant delivery device of  claim 7 , wherein the proximal element is screwed on to the distal element. 
     
     
         9 . The implant delivery device of  claim 5 , wherein the engagement member is comprised of a clamping device. 
     
     
         10 . The implant delivery device of  claim 1 , wherein the housing is comprised of an upper housing member and a lower housing member that engage each other to form a longitudinal cavity. 
     
     
         11 . The implant delivery device of  claim 1 , wherein the pusher comprises a proximal hub, the proximal hub being adjustable between a first locked configuration and a second unlocked configuration. 
     
     
         12 . An implant delivery device, comprising:
 a housing including an aperture;   a pusher extending through housing; and   a sliding element movably connected to the housing, wherein the sliding element is connected to the pusher through the aperture; and,   wherein moving the sliding element in a distal direction propels the pusher forward out of the housing.   
     
     
         13 . The implant delivery device of  claim 12 , further comprising an engagement member through which the pusher passes. 
     
     
         14 . The implant delivery device of  claim 13 , wherein the engagement member is comprised of a clamping device. 
     
     
         15 . The implant delivery device of  claim 12 , wherein the aperture is positioned on an upper end of the housing. 
     
     
         16 . The implant delivery device of  claim 12 , wherein the aperture is comprised of an elongated slot. 
     
     
         17 . The implant delivery device of  claim 16 , wherein the elongated slot extends along at least half of a length of the housing. 
     
     
         18 . The implant delivery device of  claim 12 , wherein the pusher comprises a proximal hub, the proximal hub being adjustable between a first locked configuration and a second unlocked configuration. 
     
     
         19 . The implant delivery device of  claim 12 , wherein the housing is comprised of an upper housing member and a lower housing member that engage each other to form a longitudinal cavity. 
     
     
         20 . An implant delivery device, comprising:
 a housing including an aperture;   a delivery means for delivering an implant extending through the housing;   a pusher means for pushing the implant extending through the delivery means; and   a sliding means for exposing the pusher means movably connected to the housing, wherein the sliding means is connected to the delivery means through the aperture; and,   wherein moving the sliding means in a proximal direction retracts the delivery means and exposes the pusher means.
