Short handle for a long stent

摘要

A stent delivery system for delivering a self-expanding stent includes a keel. The keel is used to pass a pushrod and a guidewire into a sheath through the tubular sidewall of the sheath, i.e., not through the lumen opening at the proximal end of the sheath. Accordingly, the entire length of travel of the proximal end of the sheath during deployment of the stent is not required to be inside of the handle, allowing the handle to be short. Since the handle is short, the handle is easy to manipulate.

主权项

1. A stent delivery system comprising:
a handle comprising a housing and a keel directly coupled to said housing; a pushrod having a proximal end connected to said keel of said handle such that said keel and said pushrod do not move relative to said housing; a stent located over a distal end of said pushrod; and a sheath constraining said stent at a distal end of said sheath, said keel extending from said housing and into said sheath through a sidewall of said sheath; and a sheath knob attached to a proximal end of said sheath; wherein said sheath knob is threadedly mounted to said housing.
