Abstract
Prosthesis deployment devices are disclosed herein. In some embodiments, the prosthesis deployment device comprises an elongate delivery catheter assembly configured for electrosurgery and also configured to retain and deploy a prosthesis. Kits comprising the prosthesis deployment devices with a prosthesis loaded into a prosthesis pod of the device are disclosed herein as well as methods of using the prosthesis deployment devices.
Claims14
A prosthesis deployment device comprising:
- an elongate delivery catheter assembly configured for electrosurgery and also configured to retain and deploy a prosthesis;
- a housing assembly operably coupled to the delivery catheter assembly and configured to connect to an electrosurgical power generator, wherein the housing assembly comprises:
- an actuator configured to proximally displace a portion of the delivery catheter assembly to deploy the prosthesis, upon actuation, and wherein the actuator is configured for one-handed operation,
- a track configured to be moved proximally by the actuator when the actuator is depressed and pivots on portions of the housing assembly,
- a sheath adapter configured to be moved proximally by the track, wherein the sheath adapter is configured to displace the portion of the delivery catheter,
- a slide assembly comprising a handle and piston, the slide assembly configured to adjust a position of the delivery catheter assembly relative to an echoendoscope,
- wherein the delivery catheter assembly is configured for insertion in a working channel of the echoendoscope and wherein the slide assembly comprises a rotatable male luer lock adapter configured to mate with a first female luer lock adapter attached to a working channel of the echoendoscope, a proximal end of the female luer lock adapter being threadingly coupled to the slide assembly, and
- a first safety button and a second safety button, wherein the first safety button comprises a first protrusion configured to engage the sheath adapter to prevent deployment of a distal portion of the prosthesis, and wherein the second safety button comprises a second protrusion configured to engage the sheath adapter to prevent deployment of a proximal portion of the prosthesis.

A method of deploying a prosthesis in a patient, the method comprising:
- inserting a delivery catheter assembly into a working channel of an echoendoscope, wherein the delivery catheter assembly comprises a prosthesis loaded into a prosthesis pod region;
- coupling the delivery catheter assembly with a working channel of the echoendoscope via a rotatable luer lock adapter, wherein a proximal end of the rotatable luer lock adapter is threadingly coupled to a slide assembly of the delivery catheter assembly;
- adjusting a position of the delivery catheter assembly relative to the echoendoscope with the slide assembly;
- engaging with one-hand a first safety button on a housing assembly to disengage a protrusion of the first safety button from a sheath adapter, prior to actuating with the same one-hand an actuator to deploy a distal end of the prosthesis;
- actuating with the same one-hand the actuator of the housing assembly operably connected to the delivery catheter assembly and thereby deploying the distal end of the prosthesis in the patient, wherein the actuator is depressed and pivots on portions of the housing assembly to move a track proximally and the track moves a sheath adapter proximally;
- engaging with the same one-hand a second safety button on the housing assembly to disengage a protrusion of the second safety button from the sheath adapter, prior to actuating with the same one-hand the actuator to deploy a proximal end of the prosthesis;
- and
- actuating with the same one-hand the actuator of the housing assembly and thereby deploying the proximal end of the prosthesis in the patient.
