摘要： The present invention is a distal protection device for use during a vascular treatment, such as angioplasty or atherectomy. A filter assembly located on the distal end of a delivery member is deployed distally of the vascular region to be treated to capture emboli released during and immediately after the procedure. The filter is then retracted to retain any captured emboli and then removed from the patient.

摘要： The present invention is a collapsible blood filter for use during a vascular procedure, such as angioplasty or stent deployment. A filter made of braided filaments is located on the distal end of a delivery member, and the filter is deployed downstream of the vascular treatment site to capture emboli released during and immediately after the procedure. Optimal braid geometry of the filter ensures that captured emboli will be retained during collapse and removal of the filter following the procedure.

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.

摘要： An endolumenal prosthesis delivery assembly includes an endolumenal prosthesis which is delivered to a desired location within a body lumen by used of first and second delivery members. The first delivery member has a prosthesis coupler that is adapted to removeably engage the prosthesis during delivery to the desired location and to release the prosthesis and implant it at the desired location. The second delivery member has an anchor on its distal end portion which is adapted to secure the second delivery member within the body lumen distally of the desired location for stenting. Once the second delivery member is anchored, the first delivery member is slideably advanced over the second delivery member until the prosthesis is positioned at the desired location. The anchor along the second delivery member according to this assembly is either an expandable member, such as a balloon, or is otherwise adapted to engage the body lumen wall, such as by use of suction or other mechanical means. An expansion member on the first delivery member, such as provided at the prosthesis coupler, expands the prosthesis to engage the body lumen wall.

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： A seal for a medical device such as a catheter is formed between two parts of the device which are capable of movement relative to each other, either axially, rotationally or both. The seal is formed by opposing sealing surfaces on each of the two parts, the surfaces being sufficiently smooth and of sufficiently close proximity that liquids having viscosities on the order of those normally used in catheters will not pass between the surfaces due to such effects as surface tension and friction. In certain embodiments, the surfaces are arranged to permit liquid to pass at a controlled rate for purposes of perfusion when desired, or the surfaces can be moved relative to one another to achieve this capability.
