Apparatus and method for accessing the wall of a body lumen while simultaneously providing zone isolation and fluid bypass capability, the apparatus comprising:

Method and apparatus for accessing the wall of a vascular structure or other body lumen while simultaneously providing zone isolation and fluid bypass capability

Apparatus and method for repairing an abnormality in the wall of a body lumen, the method comprising isolating the abnormality in the wall of the body lumen from flow in the body lumen; positioning flowable forming material adjacent to the abnormality in the wall of the body lumen; and transforming the flowable forming material into a substantially stationary state so as to repair the abnormality in the wall of the body lumen, and the apparatus comprising a supply of flowable forming material; zone isolation apparatus for isolating the abnormality in the wall of the body lumen from flow in the body lumen; and positioning apparatus for positioning the flowable forming material adjacent to the abnormality in the wall of the body lumen so as to repair the abnormality in the wall of the body lumen.

Method and apparatus for repairing vascular abnormalities and/or other body lumen abnormalities using an endoluminal approach and a flowable forming material

An expandable spherical structure for deployment in a blood vessel or other body lumen, comprising: an open frame configured to assume a collapsed configuration and an expanded configuration; and a closed face carried by the open frame; wherein the open frame is configured so as to permit substantially normal flow therethrough when the open frame is in its expanded configuration, and further wherein the closed face is configured so as to obstruct flow therethrough.

Method and apparatus for sealing an opening in the side wall of a body lumen, and/or for reinforcing a weakness in the side wall of a body lumen, while maintaining substantially normal flow through the body lumen

In one form of the invention, there is provided a method for treating rectal prolapse, the method comprising: inserting an expandable element into a prolapsed rectum via the anus; expanding the expandable element so that the expandable element securely engages the rectum; advancing the expanded element distally so as to return the prolapsed rectum to its normal, non-prolapsed state; and securing the rectum to supporting tissue whereby to retain the rectum in its normal, non-prolapsed state. In another form of the invention, there is provided an endoscope assembly for treating rectal prolapse, the endoscope assembly comprising: an endoscope; a balloon catheter; and a tacker; wherein the endoscope, balloon catheter and tacker are mounted together for insertion as a unit.
