1. A delivery system for a self-expanding medical device, comprising:
- an inner catheter with a retention surface adapted to longitudinally restrain a self-expanding medical device;
an outer sheath adapted to extend over said self-expanding medical device to radially restrain said self-expanding medical device in a compressed state;
a housing connected to said inner catheter, said housing comprising a top side and a bottom side, said top side having a longitudinal slot extending therethrough, and said bottom side comprising a generally flat surface, wherein a ratio between a width of said flat surface of said bottom side and a height between said bottom side and said top side is about 2.5;
1 to about 3.5;
1;
a slide disposed within said housing and being connected to said outer sheath;
a knob connected to said slide and extending out of said housing through said slot in said housing;
wherein said self-expanding medical device is released at a treatment site by longitudinally restraining said housing with respect to said treatment site and moving said knob longitudinally away from said treatment site within said slot of said housing, said outer sheath thereby being withdrawn from said self-expanding medical device while said inner catheter maintains said self-expanding medical device at said treatment site.

Abstract
A delivery system is provided for a self-expanding medical device. The delivery system has a handle assembly with a housing. The housing has a slot with a deployment knob extending therethrough. The self-expanding medical device is deployed by restraining the housing of the handle assembly and pulling on the deployment knob. This causes an outer sheath to withdraw proximally from an inner catheter to release the self-expanding medical device from a space between the outer sheath and inner catheter.
