Patent ID: 8500811

Claim:
A surgical delivery tool, comprising: an outer tubular shaft having a proximal end, a distal end and a lumen therebetween; an inner tubular shaft having a proximal end, a distal end, wherein the inner tubular shaft is located at least partially in the lumen of the outer tubular shaft; a handle located at the proximal end of the inner tubular shaft; a device coupler wherein the device coupler comprises a coupling base with a through lumen and an elongate coupling member comprising a proximal end and a distal end, wherein the distal end is configured with at least one radial projecting structure configured to abut the coupling base and the proximal end is configured to releasably engage the distal end of the inner tubular shaft, wherein at least a portion of the elongate coupling member is configured so as to move in the through lumen of the coupling base such that the elongate coupling member has a proximal position and a distal position, wherein, in the proximal position, the radial projecting structure on the distal end of the elongate coupling member abuts a distal surface of the coupling base and in the distal position the radial projecting structure lies distal to and separated from the distal surface of the coupling base; and a releasable lock assembly located about the distal end of the inner tubular shaft and configured to releasably engage the proximal end of the elongate coupling member of the device coupler.
