Abstract

Claims (29)

1. A medical device, comprising:

a shaft extending between a proximal end and a distal end, the shaft including a lumen therein;

a handle coupled to the proximal end of the shaft and including a mode selector, wherein the mode selector is adapted to transition between a first mode and a second mode of the medical device; and

a compressed fluid source fluidly coupled with the shaft;

wherein, in the first mode, the compressed fluid source is fluidly coupled with the shaft so as to impart a negative pressure in at least a portion of the lumen, and wherein in the second mode, the compressed fluid source is fluidly coupled with the shaft so as to impart a positive pressure in the at least a portion of the lumen.

2. The medical device of claim 1 , wherein the handle is detachably coupled with the shaft.

3. The medical device of claim 1 , wherein in the first mode the compressed fluid source is configured to draw an implant into the shaft.

4. The medical device of claim 1 , wherein the compressed fluid source includes a cartridge configured to contain a compressed fluid;

wherein the cartridge is coupled with the handle.

5. The medical device of claim 4 , wherein the cartridge is detachably coupled with the handle.

6. The medical device of claim 1 , wherein the handle defines a cavity;

wherein the compressed fluid source includes a cartridge positioned within the cavity and the cartridge is configured to contain a compressed fluid.

7. The medical device of claim 1 , wherein the mode selector includes a toggling switch.

8. The medical device of claim 1 , wherein the mode selector includes a trigger, the trigger configured to cause compressed gas to be applied to the shaft.

9. The medical device of claim 1 , including a valve mechanism fluidly interconnecting the compressed fluid source and the shaft.

10. The medical device of claim 1 , wherein the compressed fluid source includes a remote gas source positioned away from the handle; the medical device including:

a tubing assembly fluidly coupling the remote gas source with the handle, the tubing assembly having a suction line and a pressure line.

11. The medical device of claim 10 , wherein the handle includes a first half and a second half, the first half configured to receive the suction line and the second half configured to receive the pressure line.

12. The medical device of claim 1 , including a core seal at least partially received within the lumen of the shaft.

13. The medical device of claim 1 , including a core seal, a first O-ring and a second O-ring positioned between the shaft and the handle.

14. The medical device of claim 1 , including a nozzle removably coupled with the distal end of the shaft.

15. The medical device of claim 1 , including a nozzle coupled with the distal end of the shaft.

16. The medical device of claim 1 , including a flexible nozzle coupled with the distal end of the shaft.

17. The medical device of claim 1 , including a nozzle removably coupled with a distal portion of the shaft;

wherein the compressed fluid source is coupled with the distal portion of the shaft.

18. The medical device of claim 1 , wherein the mode selector is configured to toggle a valve mechanism to control a compressed fluid flow to the shaft to impart the positive pressure in the at least a portion of the lumen.

19. The medical device of claim 1 , wherein the mode selector is configured to toggle a valve mechanism to control a compressed fluid flow to the shaft to impart the negative pressure in the at least a portion of the lumen, the negative pressure configured to draw an implant into the lumen.

20. The medical device of claim 1 , including a negative pressure source in communication with the shaft and configured to draw a pre-filled breast implant into the shaft; and

a positive pressure source in communication with the shaft and configured to expel the pre-filled breast implant from the shaft, through a nozzle, and into a breast pocket of a subject.
