Abstract

A surgical portal apparatus includes a sleeve having a proximal end and a distal end that extends along a longitudinal axis, and a surgical tape. The sleeve includes an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and an outer wall configured for positioning against tissue. The inner and outer walls define at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall. The surgical tape includes a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve. The surgical tape has a first surface and a second surface, each of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups.

First claim

What is claimed is:

1. A surgical portal apparatus, which comprises:
a sleeve including a proximal end and a distal end extending along a longitudinal axis, the sleeve including an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and out the distal end of the sleeve, and an outer wall configured for positioning against tissue, the inner and outer walls defining at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall; and
a surgical tape including a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve, the surgical tape having a first surface and a second surface, at least one of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups.

2. The surgical portal apparatus of claim 1 , further comprising a seal housing joined to the proximal end of the sleeve.

3. The surgical portal apparatus of claim 1 , wherein the opening in the outer wall of the sleeve is a longitudinal slot.

4. The surgical portal apparatus of claim 3 , wherein the longitudinal slot extends along substantially the entire length of the sleeve.

5. The surgical portal apparatus of claim 1 , wherein the body portion of the surgical tape extends at least partially around the inner wall of the sleeve.

6. The surgical portal apparatus of claim 5 , wherein the surgical tape is wrapped around the inner wall of the sleeve.

7. The surgical portal apparatus of claim 1 , wherein the leading tab includes a tissue reactive component adapted to attach the leading tab to tissue within about 30 seconds to about 20 minutes of tissue exposure.

8. The surgical portal apparatus of claim 1 , wherein the leading tab includes mechanical hooks, each hook including an arm having a pointed distal end extending in a direction transverse to the longitudinal axis of the sleeve.

9. The surgical portal apparatus of claim 1 , wherein the leading tab includes a release liner fabricated from a quick dissolving or rapidly bioerodible polymeric material positioned over at least one of the first and second surfaces of the surgical tape.

10. The surgical portal apparatus of claim 1 , wherein the surgical tape is selected from the group consisting of films, foams, meshes, fibrous sheets, patches, and composite thereof.

11. The surgical portal apparatus of claim 1 , wherein the surgical tape is porous, non-porous, or combinations thereof.

12. The surgical portal apparatus of claim 1 , wherein the opening in the outer wall of the sleeve is an annular slot formed in the distal end of the sleeve.

13. The surgical portal apparatus of claim 12 , wherein the leading tab is an annular flange, the annular flange dimensioned and adapted to extend from the annular slot.

14. The surgical portal apparatus of claim 1 , wherein the surgical tape includes perforations.

15. The surgical portal apparatus of claim 1 , further comprising a rotatable knob attached to the inner wall.

16. The surgical portal apparatus of claim 1 , wherein each of the first and second surfaces of the surgical tape has at least one of tissue reactive functional groups and self-reactive functional groups.

17. A method for accessing a surgical site comprising:
introducing a surgical portal apparatus into a body cavity through a wound in tissue, the surgical portal apparatus including:
a sleeve including a proximal end and a distal end extending along a longitudinal axis, the sleeve including an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and an outer wall configured for positioning against tissue, the inner and outer walls defining at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall; and
a surgical tape including a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve, the surgical tape having a first surface and a second surface, at least one of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups;

positioning the leading tab of the surgical tape against the tissue, whereby the at least one of the tissue reactive functional groups and the self-reactive functional groups facilitate bonding of the surgical tape with the tissue of the wound;
performing surgical tasks within the body cavity with a surgical object introduced through the internal longitudinal passageway of the sleeve;
manipulating the sleeve to release the body portion of the surgical tape from the sleeve;
removing the surgical portal apparatus from the wound; and
closing the wound.

18. The method of claim 17 , wherein the opening of the outer wall is a longitudinal slot, wherein manipulating the sleeve to release the body portion of the surgical tape includes rotating the surgical portal apparatus about the longitudinal axis of the sleeve.

19. The method of claim 17 , wherein the opening of the outer wall is an annular slot in the distal end of the sleeve, wherein manipulating the sleeve to release the body portion of the surgical tape includes longitudinally moving the sleeve in a proximal direction.

20. The method of claim 17 , wherein positioning the leading tab of the surgical tape includes maintaining the surgical portal apparatus within the wound for a predetermined period of time until the tissue reactive functional groups bond with the tissue.

21. The method of claim 17 , including disposing at least one of tissue reactive functional groups and self-reactive functional groups on each of the first and second surfaces of the surgical tape.
