Abstract
An apparatus for creating an anatomic space comprising a cannula having a distal end and a proximal end, the proximal end having at least one port, the cannula having a lumen therethrough. A skin seal balloon is located on an exterior surface of a distal end of the cannula. The skin seal balloon is in fluid communication with one of the at least one port. A
tunneling shaft has a distal end and a proximal end, the tunneling shaft having an enlarged blunt tip on the distal end, the enlarged blunt tip adapted to fit within the lumen of the cannula. A handle is located on the proximal end of the tunneling shaft, the handle is configured to releasably connect to the proximal end of the cannula. A balloon is associated with a portion of the length of the tunneling shaft and a balloon cover generally surrounding the balloon and the tunneling shaft.
tunneling shaft has a distal end and a proximal end, the tunneling shaft having an enlarged blunt tip on the distal end, the enlarged blunt tip adapted to fit within the lumen of the cannula. A handle is located on the proximal end of the tunneling shaft, the handle is configured to releasably connect to the proximal end of the cannula. A balloon is associated with a portion of the length of the tunneling shaft and a balloon cover generally surrounding the balloon and the tunneling shaft.
Claims (17)
1. An apparatus for creating an anatomic space comprising:
a cannula having a distal end and a proximal end, said proximal end having at least one port, said cannula having a lumen therethrough;
a skin seal balloon located on an exterior surface of a distal end of said cannula, said skin seal balloon being in fluid communication with one of said at least one port;
a tunneling shaft having a distal end and a proximal end, said tunneling shaft having an enlarged blunt tip on said distal end, said enlarged blunt tip adapted to fit within said lumen of said cannula;
a handle on said proximal end of said tunneling shaft, said handle configured to releasably connect to said proximal end of said cannula;
a balloon associated with a portion of the length of said tunneling shaft; and a balloon cover generally surrounding said balloon and said tunneling shaft.
a cannula having a distal end and a proximal end, said proximal end having at least one port, said cannula having a lumen therethrough;
a skin seal balloon located on an exterior surface of a distal end of said cannula, said skin seal balloon being in fluid communication with one of said at least one port;
a tunneling shaft having a distal end and a proximal end, said tunneling shaft having an enlarged blunt tip on said distal end, said enlarged blunt tip adapted to fit within said lumen of said cannula;
a handle on said proximal end of said tunneling shaft, said handle configured to releasably connect to said proximal end of said cannula;

2. The apparatus of claim 1, wherein a portion of said tunneling shaft is within said cannula and a portion of said distal end of said tunneling shaft protrudes from said cannula.
3. The apparatus of claim 1, wherein said balloon is generally contained around said tunneling shaft that protrudes from said cannula.
4. The apparatus of claim 1, further including a port cover releasably connected to said cannula, said port configured to deny access to said at least one air port when connected to said cannula.
5. The apparatus of claim 1, further including a tunneling shaft guide configured to guide said tunneling shaft with said lumen of said cannula.
6. The apparatus of claim 5, wherein said tunneling shaft guide comprises a collar slidably connected to said tunneling shaft.
7. The apparatus of claim 5, wherein said tunneling shaft guide comprises:
a sleeve having an end collar and a stepped collar;
a guide intermediate said stepped collar and said end collar, said guide having at least two fingers that cantilever outward to conform to an outer diameter of the stepped collar.

a guide intermediate said stepped collar and said end collar, said guide having at least two fingers that cantilever outward to conform to an outer diameter of the stepped collar.
8. The apparatus of claim 7, whereby in a first position said guide and said stepped collar interact to cause said outer diameter of said guide to exceed said inner diameter of said lumen and in a second position said guide and said stepped collar interact to reduce said outer diameter of said guide to fit within said lumen.
9. An apparatus for creating an anatomic space comprising:
a tubular member having a lumen extending therethrough, said tubular member having a distal end and a proximal end and an inner surface and an outer surface;
a skin seal balloon on said outer surface of said distal end;
a substantially rigid tunneling shaft slidably mounted in said lumen of said tubular member, said tunneling shaft having a blunt distal end for tunneling bluntly through tissue;
a deflated balloon disposed alongside said tunneling shaft;
means for securing said balloon to said tunneling shaft;
a sheath enclosing said balloon, said sheath having a weakened region extending longitudinally thereof permitting said sheath to be removed from said balloon.
a tubular member having a lumen extending therethrough, said tubular member having a distal end and a proximal end and an inner surface and an outer surface;
a skin seal balloon on said outer surface of said distal end;
a substantially rigid tunneling shaft slidably mounted in said lumen of said tubular member, said tunneling shaft having a blunt distal end for tunneling bluntly through tissue;
a deflated balloon disposed alongside said tunneling shaft;
means for securing said balloon to said tunneling shaft;
a sheath enclosing said balloon, said sheath having a weakened region extending longitudinally thereof permitting said sheath to be removed from said balloon.
10. The apparatus of claim 9, further including a clamp on said tubular member intermediate said skin seal balloon and said proximal end, said clamp configured to temporarily secure said tubular member to a patient.
11. The apparatus of claim 10, wherein said clamp further includes a resilient skin contact portion to engage skin on said patient thereby compressing said skin intermediate said resilient skin contact portion and said skin seal balloon.
12. The apparatus of claim 9, further including means for inflating said balloon after said sheath has been removed to create the anatomic space.
13. The apparatus of claim 9, wherein said deflated balloon further includes a stop-cock valve configured to control fluid flow into said deflated balloon.
14. The apparatus of claim 9, further including a skin seal balloon port in fluid communication with said skin seal balloon.
15. The apparatus of claim 9, further including a handle connected to said sheath, said handle configured to cover said skin seal balloon port until said sheath is removed from said balloon.
16. The apparatus of claim 14, further including a stop-cock valve connected to said skin seal balloon port.
17. The apparatus of claim 9, further including a tunneling shaft guide configured to generally center said tunneling shaft within said lumen.
