    摘要： Methods and devices for forming an anastomosis utilize a graft vessel secured to a vessel coupling that is fixed to a target vessel without using suture. The vessel coupling may be collapsed for introduction into the target vessel and then expanded to engage the vessel wall. The vessel coupling may be a stent attached to a graft vessel to form a stent-graft assembly. The anastomosis may be carried out to place the graft and target vessels in fluid communication while preserving native proximal flow through the target vessel, which may be a coronary artery. As a result, blood flowing through the coronary artery from the aorta is not blocked by the vessel coupling and thus is free to move past the site of the anastomosis.

    摘要： Methods, systems, devices and kits for performing lung volume reduction in patients suffering from chronic obstructive pulmonary disease or other conditions using and comprising minimally invasive instruments introduced through the mouth (endotracheally) to isolate a target lung tissue segment from other regions of the lung and reduce lung volume. Isolation is achieved by deploying an obstructive device in a lung passageway leading to the target lung tissue segment. Once the obstructive device is anchored in place, the segment can be aspirated through the device. This may be achieved by a number of methods, including coupling an aspiration catheter to an inlet port on the obstruction device and aspirating through the port. Or, providing the port with a valve which allows outflow of gas from the isolated lung tissue segment during expiration of the respiratory cycle but prevents inflow of air during inspiration. In addition, a number of other methods may be used. The obstructive device may remain as an implant, to maintain isolation and optionally allow subsequent aspiration, or the device maybe removed at any time.

    摘要： A biologically implantable artificial sphincter system and methods of using the same is disclosed. The artificial sphincter system disclosed herein comprises a sphincter band and a piezoelectric element, both of which are adapted and configured for coordinated operation to open and/or close a body cavity. The artificial sphincter systems are useful in the treatment of urinary incontinence, fecal incontinence, and reflux disorders. The implanted artificial sphincter can also provide a signal to the recipient to urinate or defecate.
