Apparatus and methods for performing percutaneous transgastric or bi-transgastric minimally invasive surgical procedures targeting various organs and tissues of the gastrointestinal (GI) tract are provided. In one aspect of the invention, a percutaneous transgastric surgical port having at least one retraction tab disposed at a proximal end thereof is provided, wherein the at least one retraction tab is adapted for manipulating the percutaneous transgastric surgical port. In another aspect of the invention, a method of disposing one or more transgastric surgical ports in the gastric wall of a patient is provided, the one or more ports being utilized to perform a transgastric or bi-transgastric procedure in which the stomach itself may serve as a surgical port.

A medical device and procedure is provided for rapidly forming an anastomosis between two viscera, while minimizing the potential of breaching the mural boundary. The medical device generally includes a first magnet assembly and a second magnet assembly. Each of the magnet assemblies includes a magnetic core defining an axial opening and at leas one includes a transverse passageway. The axial openings are sized to correspond with the size of the desired anastomosis. The transverse passageway is size to permit passage of a wire guide therethrough for placement of the first and second magnet assemblies. The medical device approximates the tissues of the two viscera, such that endoscopic excision and affixation of the tissues may be performed to create the anastomosis.

A medical device and a method of using such medical device for removing targeted tissue from a body lumen in a patient is presented. The method generally comprises placing the distal end of the device through a natural orifice in the patient to a location that is proximate to the targeted tissue; deploying a T-anchor fastened to a suture strand through the targeted tissue; deploying a loop anchor into the tissue of the body lumen spaced away from the targeted tissue, whereas the suture strand is slidably received by the loop anchor; applying tension to the suture strand; cutting the tissue at a predetermined depth around the periphery of the targeted tissue; and removing the targeted tissue along with the T-anchor from the body lumen. The tension applied to the targeted tissue maintains the targeted tissue in a raised position and/or allows the physician to manipulate the targeted tissue relative to the tissue that is proximate to it.

An extremity supporting exercise system is described. The system includes two knee sliders and two hand sliders. Each knee slider includes a knee pad and a knee base. The knee pad includes a recessed portion that is adapted to receive a user's knee. A patella support is disposed within the knee portion to support the user's patella when using the knee slider. Alternatively, each hand slider includes a hand pad and a hand base. The hand pad includes a series of finger indentations that are flanked by thumb receptacles. Importantly, the knee base and hand base are formed of a rigid and slippery material to allow the sliders to easily slide across a ground surface. Thus, through use of the exercise system, a user can support their hands and knees while sliding the hands and knees across a ground surface to perform a variety of exercises.
