An improved endoscopic tissue apposition device (50) having multiple suction ports (86) permits multiple folds of tissue to be captured in the suction ports (86) with a single positioning of the device (50) and attached together by a tissue securement mechanism such as a suture (14), staple or other form of tissue bonding. The improvement reduces the number of intubations required during an endoscopic procedure to suture tissue or join areas of tissue together. The suction ports (86) may be arranged in a variety of configurations on the apposition device (50) to best suit the desired resulting tissue orientation. The tissue apposition device (50) may also incorporate tissue abrasion means (852) to activate the healing process on surfaces of tissue areas that are to be joined by operation of the device to promote a more secure attachment by permanent tissue bonding.

An electrode catheter is introduced into a hollow anatomical structure, such as a vein, and is positioned at a treatment site within the structure. Tumescent fluid is injected into the tissue surrounding the treatment site to produce tumescence of the surrounding tissue which then compresses the vein. The solution may include an anesthetic, and may further include a vasoconstrictive drug that shrinks blood vessels. The tumescent swelling in the surrounding tissue causes the hollow anatomical structure to become compressed, thereby exsanguinating the treatment site. Energy is applied by an electrode catheter in apposition with the vein wall to create a heating effect. The heating effect causes the hollow anatomical structure to become molded and durably assume the compressed dimensions caused by the tumescent technique. The electrode catheter can be moved within the structure so as to apply energy to a large section of the hollow anatomic structure. In a further aspect, the location of the electrodes is determined by impedance monitoring. Also, temperature sensors at the treatment site are averaged to determine the site temperature.
