Abstract

This invention relates generally to an implantable subcutaneous access device for performing an endoscopic operative procedure, and the method of using the subcutaneous access device. The subcutaneous access device is comprised of a portal sleeve, the portal sleeve preferably being angulated to provide an angulated port of entry for a surgical device through cutaneous layers of the body. A subcutaneous flange is connected to the portal sleeve in order to secure the subcutaneous access device under the cutaneous layer. An access flange which may function as a surgical mat is also connected to the portal sleeve. The method of using the subcutaneous access device consists of forming a transdermal incision, inserting the subcutaneous access device into and through the incision, and inserting and manipulating a surgical device through the port of entry to thereby perform a surgical procedure.

Claims

1. An implantable subcutaneous access device for device for performing an endoscopic operative procedure comprising:

a portal sleeve, said portal sleeve providing a port of entry through a cutaneous layer of a body;

a subcutaneous flange connected to said portal sleeve, said subcutaneous flange being adapted to be secured under said cutaneous layer; and

an access flange connected to said portal sleeve so as to be at a preformed oblique angle to the portal sleeve, said access flange being in a spaced apart relationship with said subcutaneous flange and being adapted to be located external to said body.

2. The implantable subcutaneous access device as recited in claim 1, wherein said subcutaneous flange provides a surface area to prevent unintended removal of the implantable subcutaneous access device and said access flange provides a surface area to prevent foreign particles from entering into said port of entry during the endoscopic operative procedure.

3. The implantable subcutaneous access device as recited in claim 2, wherein said portal sleeve is in the shape of a cylindrical stem.

4. The implantable subcutaneous access device as recited in claim 3, wherein the access flange and the subcutaneous flange have substantially annular shapes.

5. The implantable subcutaneous access device as recited in claim 4, wherein the surface area of the access flange is greater than the surface area of the subcutaneous flange.

6. The implantable subcutaneous access device as recited in claim 5, wherein said access flange is in a parallel spaced apart relationship with respect to said subcutaneous flange.

7. The implantable subcutaneous access device as recited in claim 6, wherein said portal sleeve further includes a proximal end and a distal end, said subcutaneous flange being connected at the distal end, and said access flange being connected at the proximal end.

8. An implantable subcutaneous access device for performing an endoscopic operative procedure comprising:

a portal sleeve providing a port of entry through a cutaneous layer of a body;

a subcutaneous flange connected to said portal sleeve so as to be at a preformed oblique angle to the portal sleeve, said subcutaneous flange providing a surface area to prevent unintended removal of the subcutaneous access device; and

an access flange connected to said portal sleeve, said access flange providing a surface area to prevent foreign particles from entering into said port of entry during the endoscopic operative procedure,

said access flange being in a spaced apart relationship with said subcutaneous flange.

9. The implantable subcutaneous access device as recited in claim 8, wherein said portal sleeve is in the shape of a cylindrical stem.

10. The implantable subcutaneous access device as recited in claim 9, wherein the access flange and the subcutaneous flange have substantially annular shapes.

12. A method of performing an endoscopic operative procedure on a body comprising the steps of:

forming an incision extending from an external surface of the body to a subcutaneous portion of the body;

placing a subcutaneous access device into said incision, said subcutaneous access device providing a port of entry to the subcutaneous portion of the body, said subcutaneous access device comprising a portal sleeve, a subcutaneous flange connected at one end of said portal sleeve, and an access flange connected to said portal sleeve in a spaced apart relationship relative to said subcutaneous flange, wherein said access flanged has a substantially annular shape;

inserting an endoscopic surgical device into and through the port of entry to perform the endoscopic operative procedure; and

manipulating said surgical instrument subcutaneously to thereby perform the endoscopic surgical procedure.

11. The implantable subcutaneous access device as recited in claim 12, wherein said access flange is in a parallel relationship with said subcutaneous flange and at an oblique angle relative to said portal sleeve.

13. The method as recited in claim 12, wherein said subcutaneous flange provides a surface area to prevent unintended removal of the subcutaneous access device, and said access flange provides a surface area to prevents foreign particles from entering into said port of entry during the endoscopic operative procedure.

14. The method as recited in claim 13, wherein said port of entry is angulated.

15. The method as recited in claim 14, wherein said portal sleeve is in the shape of a cylindrical stem.

16. The method as recited in claim 15, wherein the subcutaneous flange has a substantially annular shape.

17. The method as recited in claim 16, wherein the surface area of the access flange is greater than the surface area of the subcutaneous flange.

18. The method as recited in claim 17, wherein said access flange is in a parallel spaced apart relationship with respect to said subcutaneous flange and at an oblique angle relative to said portal sleeve.

19. The method of as recited in claim 12, comprising the further step of:

severing tissue with said surgical instrument.

20. The method of as recited in claim 19, comprising the further step of:

remotely viewing the surgical procedure being performed via the port of entry.
