Abstract

An apparatus and method for performing a surgical procedure on first and second adjacent circular portions of mucosa of tubular tissue wherein a first supporting member supports the first circular portion of mucosa, a second supporting member supports the second adjacent circular portion of mucosa and with a body tubular tissue holder positioned on the first or second supporting members. The body tubular tissue holder has a plurality of holding members oriented to hold the first or second adjacent circular portions of mucosa to secure the first and second adjacent portions of mucosa to provide for attachment of the first circular portion of mucosa to the adjacent second circular portion of mucosa.

7. The apparatus of claim 1 wherein the body tubular tissue holder is formed as part of the second supporting member.

8. The apparatus of claim 1 wherein the body tubular tissue holder is formed separately from the first or second supporting member and includes a washer that supports the holding members.

9. The apparatus of claim 8 additionally including a retaining member connected to the body tubular tissue holder to retain the body tubular tissue holder in position relative to the first or second supporting member.

10. The apparatus of claim 1 wherein the first and second supporting members form a circular stapler to provide the attachment of the first and second adjacent portions of mucosa.

11. The apparatus of claim 10 additionally including a central shaft interconnecting the first and second supporting members and wherein the body tubular tissue holder is positioned around the central shaft.

12. In an apparatus for performing a medical procedure on first and second adjacent circular portions of mucosa of tubular tissue which comprises,

a first supporting member adapted to support the first circular portion of mucosa,

a second supporting member adapted to support the second adjacent circular portion of mucosa, means coupled to the first and second supporting members for providing for attachment of the first circular portion of mucosa to the adjacent second circular portion of mucosa, and

a body tubular tissue holder positioned on the first or second supporting members and having a plurality of holding members and oriented to hold the first or second adjacent circular portions of mucosa to secure the first and second adjacent portions of mucosa for attachment to each other.

13. The apparatus of claim 12 wherein the first and second adjacent circular portions of tubular tissue include mucosa and submucosa and wherein the first and second supporting members and the holding members provide for attachment of the adjacent circular portions of mucosa and submucosa to each other.

14. The apparatus of claim 12 wherein the body tubular tissue holder is positioned on the first supporting member.

15. The apparatus of claim 12 wherein the body tubular tissue holder is positioned on the second supporting member.

16. The apparatus of claim 12 wherein the holding members are formed by spikes.

17. The apparatus of claim 12 wherein the body tubular tissue holder is formed as part of the first supporting member.

18. The apparatus of claim 12 wherein the body tubular tissue holder is formed as part of the second supporting member.

19. The apparatus of claim 12 wherein the body tubular tissue holder is formed separately from the first or second supporting member and includes a washer that supports the holding members.

20. The apparatus of claim 19 additionally including a retaining member connected to the body tubular tissue holder to retain the body tubular tissue holder in position relative to the first or second supporting member.

21. The apparatus of claim 12 wherein the first and second supporting members form a circular stapler to provide the attachment of the first and second adjacent portions of mucosa.

22. The apparatus of claim 21 additionally including a central shaft interconnecting the first and second supporting members and wherein the body tubular tissue holder is positioned around the central shaft.

23. A method for performing a medical procedure on first and second adjacent circular portions of mucosa of tubular tissue wherein a first supporting member is adapted to support the first circular portion of mucosa and a second supporting member is adapted to support the second adjacent circular portion of mucosa and to provide for attachment of the first circular portion of mucosa to the adjacent second circular portion of mucosa which comprises the following steps,

providing a body tubular tissue holder having a plurality of holding members, positioning the body tubular tissue holder on the first or second supporting member, and

providing the plurality of holding members to be oriented to hold the first or second adjacent circular portions of mucosa to secure the first and second adjacent portions of mucosa for attachment to each other,

24. The method of claim 23 wherein the first and second adjacent circular portions of tubular tissue include mucosa and submucosa and wherein the first and second supporting members and the holding members provide for attachment of the adjacent circular portions of mucosa and submucosa to each other.

25. The method of claim 23 wherein the body tubular tissue holder is positioned on the first supporting member.

26. The method of claim 23 wherein the body tubular tissue holder is positioned on the second supporting member.

27. The method of claim 23 wherein the holding members are formed by spikes.

28. The method of claim 23 wherein the body tubular tissue holder is formed as part of the first supporting member.

29. The method of claim 23 wherein the body tubular tissue holder is formed as part of the second supporting member.

30. The method of claim 23 wherein the body tubular tissue holder is formed separately from the first or second supporting member and includes a washer that supports the holding members.

31. The method of claim 30 additionally including a retaining member connected to the body tubular tissue holder to retain the body tubular tissue holder in position relative to the first or second supporting member.

32. The method of claim 23 wherein the first and second supporting members form a circular stapler to provide the attachment of the first and second adjacent portions of mucosa.
