Abstract

A reinforced access assembly is provided. The access assembly includes a compressible body having proximal and distal ends and a substantially hourglass-shaped central portion extending therebetween. The compressible body defining at least a first lumen configured to receive an instrument in a sealing manner. The access assembly further includes a reinforcing mechanism extending between the proximal and distal ends of the compressible body. The reinforcing mechanism includes a plurality of rib members configured to permit compression of the compressible body during insertion into an incision and return the compressible body to an uncompressed condition following insertion.

Claims

1. An access assembly comprising:

a compressible body having proximal and distal ends and an hourglass-shaped central portion extending therebetween, the compressible body defining at least a first lumen configured to receive an instrument in a sealing manner when the instrument is received through the at least first lumen, the compressible body defining at least one channel between the proximal and distal ends, the at least one channel enclosed within a wall of the central portion, wherein the at least one channel defines an opening in at least one of the proximal and distal ends; and

a reinforcing mechanism selectively insertable into the at least one channel and extending between the proximal and distal ends of the compressible body, the reinforcing mechanism including a plurality of rib members configured to permit compression of the compressible body during insertion into an incision and return the compressible body to an uncompressed condition following insertion, wherein the reinforcing mechanism is maintained entirely within the compressible body when the reinforcing mechanism is received within the at least one channel.

2. The access assembly of claim 1, further including an upper rim at the proximal end of the body.

3. The access assembly of claim 2, further including a lower rim at the distal end of the body.

4. The access assembly of claim 2, wherein each of the plurality of rib members includes a flange received within the upper rim.

5. The access assembly of claim 3, wherein each of the plurality of rib members includes a flange received within the lower rim.

6. The access assembly of claim 3, wherein each of the plurality of rib members includes a first flange located in the proximal end of the body and a second flange located in the distal end of the body.

7. The access assembly of claim 4, wherein each of the flanges includes a lip for more securely receiving the rib members within the compressible body.

8. The access assembly of claim 5, wherein each of the flanges includes a lip for more securely receiving the rib members within the compressible body.

9. The access assembly of claim 6, wherein each of the flanges includes a lip for more securely receiving the rib members within the compressible body.

10. The access assembly of claim 1, wherein the compressible body includes three lumen.

11. The access assembly claim 1, wherein the compressible body is composed of at least one of silicone, thermoplastic elastomers (TPE), rubber, foam, or gel.

12. The access assembly of claim 1, wherein the reinforcing mechanism further includes one or more holes configured to accept one or more hoops.

13. An access assembly comprising:

a compressible body having proximal and distal ends and an hourglass-shaped central portion extending therebetween, the compressible body defining at least a first lumen configured to receive an instrument in a sealing manner, wherein the compressible body forms a seal about the instrument when the instrument is received through the at least first lumen, the compressible body defining a plurality of channels between the proximal and distal ends, the channels enclosed within a wall of the central portion; and

a reinforcing mechanism extending between the proximal and distal ends of the compressible body and maintained entirely within the compressible body, the reinforcing mechanism including a plurality of rib members configured to permit compression of the compressible body during insertion into an incision and return the compressible body to an uncompressed condition following insertion, wherein each of the plurality of rib members includes at least one flange received within a proximal rim of the proximal end of the compressible body, and each of the rib members disposed in one of the channels.

14. An access assembly comprising:

a compressible body having proximal and distal ends and an hourglass-shaped central portion extending therebetween, the compressible body defining at least a first lumen configured to receive an instrument in a sealing manner, the compressible body defining a plurality of channels between the proximal and distal ends, each channel enclosed within a wall of the central portion; and

a reinforcing mechanism extending between the proximal and distal ends of the compressible body and maintained entirely within the compressible body, the reinforcing mechanism including a plurality of rib members configured to permit compression of the compressible body to a compressed condition during insertion of the compressible body into an incision and expands the compressible body to an uncompressed condition following insertion of the compressible body within the incision, each rib member disposed in one of the channels, wherein the reinforcing mechanism further includes at least one wire hoop connecting each of the plurality of rib members.

15. The access assembly of claim 14, wherein a first wire hoop extends between each of the plurality of rib members.

16. The access assembly of claim 14, wherein the first wire hoop connects a proximal end of each of the plurality of rib members and a second wire hoop connects a distal end of each of the plurality of rib members.

17. An access assembly comprising:

a compressible body having a proximal end and a distal end and an hourglass-shaped central portion extending therebetween, the compressible body defining a plurality of lumens each configured to receive an instrument in a sealing manner, the compressible body defining a plurality of channels between the proximal end and the distal end, the plurality of channels being enclosed within a wall of the central portion, wherein the plurality of channels each defines an opening in one of the proximal end and the distal end; and

a reinforcing mechanism including a plurality of rib members removable from within the plurality of channels and extending between the proximal end and the distal end of the compressible body, the reinforcing member configured to permit compression of the compressible body during insertion into an incision and return the compressible body to an uncompressed condition following insertion, wherein the reinforcing mechanism is maintained entirely within the compressible body when the reinforcing mechanism is received within the plurality of channels.

18. The access assembly of claim 17, further including an upper rim at the proximal end of the body and a lower rim at the distal end of the body.

19. The access assembly of claim 18, wherein each of the plurality of rib members includes a flange received within one of the upper rim and the lower rim.
