Apparatuses for the implantation of medical devices and methods of use thereof
A medical device may include a shaft extending between a proximal end and a distal end. The shaft may include a lumen therein. The medical device may include a handle coupled to the proximal end of the shaft and may include a mode selector. The mode selector may be adapted to transition between a first mode and a second mode of the medical device. The medical device may further include a compressed fluid source. In the first mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a negative pressure in at least a portion of the lumen. In the second mode, the compressed fluid source may be fluidly coupled with the shaft so as to impart a positive pressure in the at least a portion of the lumen.
1. A method of operating a medical device including a shaft and a handle, the method comprising:
applying a vacuum pressure to a lumen of the shaft to draw an implant into the lumen; and
applying an expulsion pressure to the lumen via an actuator to expel the implant from a distal end of the shaft through a tapered nozzle, wherein the implant is a breast implant or a gluteal implant, and drawing the implant into the lumen compresses the implant.
2. The method of claim 1 , wherein the shaft compresses the implant to a profile diameter in the range of about 1.0 cm to about 3.0 cm.
3. The method of claim 1 , further comprising coupling the shaft to a package containing the implant before applying the vacuum pressure.
4. The method of claim 3 , wherein the package is a sterile package that contains a saline solution or a lubricant.
5. The method of claim 1 , wherein the medical device is coupled to a source of compressed fluid.
6. The method of claim 5 , wherein the source of compressed fluid is a centralized gas supply, and the medical device further comprises a tubing assembly attached to the centralized gas supply during expulsion of the implant.
7. The method of claim 1 , wherein the shaft has an inner diameter ranging from about 1-3 inches.
8. The method of claim 1 , wherein the nozzle is detachable from the shaft, and the method further comprises attaching the nozzle to the distal end of the shaft after applying the vacuum pressure.
9. The method of claim 1 , wherein the implant is expelled through the nozzle into an incision of a human subject, the incision having a size of about 1.0 cm to about 3.0 cm.
10. The method of claim 3 , wherein the implant s a breast implant comprising a silicone filling gel.
11. A method of operating a medical device including a shaft and a handle detachably coupled to the shaft, the method comprising:
applying a vacuum pressure to a lumen of the shaft to draw an implant into the lumen;
attaching the shaft to the handle via complementary mating elements, wherein a distal end of the shaft includes a tapered nozzle; and
applying an expulsion pressure to the lumen via an actuator coupled to the handle to expel the implant from the shaft through the nozzle and into an incision of a human subject.
12. The method of claim 11 , wherein the incision has a size of about 1.0 cm to about 3.0 cm.
13. The method of claim 11 , wherein the implant is a breast implant or a gluteal implant.
14. The method of claim 11 , wherein the medical device further comprises a tubing assembly with a pressure line extending through a body of the handle, the pressure line being in communication with a source of compressed fluid during expulsion of the implant.
15. The method of claim 11 , wherein the implant is drawn into the lumen from a package containing saline solution or a lubricant.
16. The method of claim 11 , wherein the device includes a pressure relief valve to relieve excess pressure within the shaft.
17. A method of operating a medical device, the method comprising:
drawing an implant into a shaft of the medical device by applying a negative pressure, the implant being compressed in the shaft, wherein the implant is drawn through a distal end of the shaft by applying the negative pressure to a proximal end of the shaft; and
expelling the implant from the shaft and through a tapered nozzle of the medical device by applying a positive pressure.
18. The method of claim 17 , wherein:
the tapered nozzle is uncoupled from the shaft during the drawing step; and
the tapered nozzle is coupled to the shaft during the expelling step.
19. The method of claim 17 , further comprising inserting the tapered nozzle through an incision of a human subject before the expelling step, the incision having a size of about 1.0 cm to about 3.0 cm, whereby the expelling step comprises expelling the implant through the incision and into the human subject.
20. The method of claim 17 , wherein the negative pressure is applied by a venturi vacuum.
21. The method of claim 17 , wherein the negative pressure is applied by a compressed gas cartridge.
22. The method of claim 17 , further comprising actuating a toggle switch to alternate between the negative pressure and the positive pressure.
23. The method of claim 17 , wherein the positive and negative pressures are 25 psi.
24. The method of claim 17 , wherein the positive and negative pressures are 30 psi.
