A modular prosthetic device is provided for replacement of the knee. The device is assembled from a plurality of components, each of which can be inserted through a small incision. After inserting the components through the incision, the device can be assembled within the knee cavity. The modularity of the device enables a surgeon to replace only those regions of the knee that are diseased or damaged, thereby avoiding a complete knee replacement. If, at a later time, additional regions of the knee become diseased or damaged, those additional regions of the knee can be replaced by additional device components and those additional components can be connected to the previously implanted components. By replacing only those regions of the knee that are diseased or damaged and by implanting each of the components through the small incision, the surgery is minimally invasive and, therefore, requires reduced time for healing and rehabilitation.

A method for treating obstructive sleep disorders includes accessing the interior of the tongue through a sublingual incision; advancing an instrument through the incision into the interior of the tongue; and instantaneously removing an amount of tissue from the interior of the base of the tongue with the instrument. The present invention includes forming a cavity or plurality of channels in the tongue. The cavity may be collapsed using a suture, fastener or bioadhesive. An emplaced suture may be provided to hold the cavity in a collapsed position thereby reducing the degree of obstruction. Additionally, thermal energy may be applied to the tissue surface immediately surrounding the channels to cause thermal damage to the tissue surface, thereby creating hemostasis and stiffening the surrounding tissue structure.

A device is provided to assist in closing an incision through body tissue that comprises a tubular body sized for introduction through the incision and carrying a plurality of stabilizer elements at the distal end thereof. The stabilizer elements are configured to be deployed within the body cavity to engage the lowermost tissue layer. In one method, the device is pulled with the stabilizer elements deployed to retract the body tissue away from adjacent body structure. In another method, a plurality of needle tips carrying sutures are guided through the body tissue to a retention device at the ends of the stabilizer elements. With the needle tips captured in the retention devices, the device is withdrawn from the incision so that the sutures form ligatures that can be tied off to close the incision.

Methods, systems, devices and assemblies are provided for treating a patient by: making an incision or puncture though the patient's skin over the abdominal cavity; establishing an initial tract through an opening formed by the incision or puncture; advancing an instrument through the tract; contacting a distal end portion of the instrument against an inner surface of the abdominal cavity; driving at least one stitching needle through the inner surface of the abdominal cavity; continuing the driving until the at least one stitching needle exits the inner surface of the abdominal cavity; anchoring a suture carried by each of the at least one stitching needle to a suture anchor at an exit location, respectively; and applying tension to each of the sutures.

A method for treating obesity by reducing the volume and/or alter the functioning of the gastric cavity to limit food consumption and induce early satiety. The method includes accessing the cavity endoscopically to visualize the interior of the cavity. The peritoneal cavity is accessed through a small incision in the abdominal wall. Using endoscopic visualization, suture anchoring devices are introduced into the peritoneal cavity through the incision and deployed from the exterior surface through the gastric cavity wall. Suture from pairs of the anchoring devices is drawn through the gastric cavity wall and tightened outside of the cavity to form a serosa to serosa plication. Any number of plications may be formed in the cavity wall and the contacting tissue within a plication may be treated to promote healing and a more durable bond.

An endovascular surgical method comprises the steps of (1) incising a patient to gain access to the interior of a selected blood vessel, (2) inserting a cannula through an aperture formed in a sealing member comprising an elastomeric membrane having an aperture for receiving the cannula, an elongated wall portion surrounding the aperture, an outer flange region, an expandable bellowed intermediate portion between the flange region and the elongated wall portion, and a layer of adhesive on the bottom surface of the flange region, (3) orienting the membrane so that the bottom surface of the flange region contacts the patient's skin when the cannula is inserted through the incision, the aperture and cannula being relatively sized to form a tight fit and seal around the cannula, and (4) perform surgery from within the selected blood vessel by inserting and withdrawing surgical instruments through the cannula to so that the intermediate membrane portion resiliently supports the cannula for movement against its elongated wall portion without transmitting stress to the flange portion that would cause the flange portion to pull away from the patient's skin.
