摘要： A system and method for endoscopically forming an anastomosis between two naturally adjacent points in the digestive tract. The system and method utilizes elongate magnetic devices that, when connected across a tissue boundary, necrose tissue until an anastomosis forms and the devices are passed naturally. Despite the elongate shape of the devices, the resulting anastomosis is substantially round. As such, round anastomoses can be formed having increased diameters merely by increasing the lengths of the devices, obviating the need for wider endoscopes.

摘要： In some embodiments, a method includes a shaft having a side catheter guide attached thereto via a guide coupler into an inferior vena cava and a superior vena cava such that the guide coupler is disposed in a right atrium, and applying a distal force to a proximal portion of the side catheter guide such that a distal end of the side catheter guide deflects laterally about the guide coupler towards a septum. The method further includes extending a side catheter that is disposed within the side catheter guide distally from the side catheter guide towards and into contact with the septum. The method further includes, with the side catheter in contact with the septum, extending a septum penetrator that is slidably disposed within the side catheter distally from the side catheter such that the septum penetrator pierces the septum.

摘要： A method and apparatus for treating stenoses at bifurcated regions of body lumens is disclosed. A balloon catheter system is disclosed comprising two balloon catheters, or a balloon catheter having a bifurcated distal end, with a linking guide wire lumen at the distal end of one balloon catheter, or one branch of the bifurcated catheter, for linking the two balloons or branches such that the device can be tracked to a treatment site. Once at the treatment site, the balloon catheters or branches of the bifurcated distal end can be unlinked and separately positioned within the branches of the bifurcated body lumen. The apparatus can also serve as a delivery system for multiple prostheses or a bifurcated endoluminal prosthesis.

摘要： The balloon portion of a balloon catheter for implanting a stent structure is at least initially retained laterally to a guide wire by passing the guide wire axially along the balloon inside the stent structure but not through the interior of the balloon or any permanent guide wire lumen at the location of the balloon. The initially deflated balloon may be folded laterally into a plurality of folds, and the guide wire may pass between the folds or outside the folds as desired. Guide wire lumens may be provided distally and/or proximally of the balloon. An elastic sleeve may be provided around the balloon to help keep the balloon folded prior to inflation and to help refold the balloon during and after deflation. If an elastic sleeve is provided, the guide wire may pass along the balloon inside the sleeve.

摘要： An endolumenal medical device assembly is provided for use in a bifurcation region of a body lumen. An expandable prosthesis, preferably an endolumenal support device such as a stent, is included in the assembly and is adjustable from a radially collapsed condition to a radially expanded condition. The expandable prosthesis further includes a prosthesis passageway and a side port through which the prosthesis passageway communicates externally of the prosthesis. A dilator or an access device is engaged within the prosthesis passageway and also through the side port while the expandable prosthesis is in the radially collapsed condition. By coupling a guidewire to an access device engaged within the side port and positioning the guidewire therein, the expandable prosthesis may be positioned in the bifurcation region such that its distal end portion is in a first branch lumen extending from the bifurcation, its proximal end portion is in a common proximal lumen of the bifurcation region, and the side port is aligned with an entrance zone to a second branch lumen extending from the bifurcation. When the expandable prosthesis is positioned at the bifurcation region in this orientation, the access device maintains percutaneous translumenal access to the second branch lumen through the prosthesis passageway and the side port while the expandable prosthesis is adjusted from the radially collapsed condition to the radially expanded condition. In addition, a dilator when engaged within the side port is adapted to expand the bore formed by the side port from an initial inner diameter to a larger expanded inner diameter. A second, lateral expandable prosthesis can also be coupled to the first expandable prosthesis at a location adjacent to the side port such that the dilator or access device extending through the side port is engaged within a lateral prosthesis lumen, extending through the lateral expandable prosthesis.
