Assignee:

Medtronic Ave, Inc. - Santa Rosa CA

International Classification:

A61M 2900

US Classification:

606200, 606159

Abstract:

The present invention is a distal protection device for use with a delivery member. A filter assembly is located on the distal end of the delivery member. The filter is deployed distally of the 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.

International Classification:

US Classification:

623 135, 623 111, 623 127

Abstract:

An endolumenal medical device assembly is provided for use in a bifurcation region of a body lumen. An expandable prosthesis, 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 includes a prosthesis passageway and a side port. 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. 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 so positioned 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. A dilator may also to expand the bore formed by the side port from an initial inner diameter to a larger expanded inner diameter.

International Classification:

A61M 2900

US Classification:

606200, 606191

Abstract:

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.

US Classification:

606200

Abstract:

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.

International Classification:

A61F 206

US Classification:

623 111

Abstract:

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.

US Classification:

623 111, 623 135

Abstract:

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.

International Classification:

US Classification:

604 95

Abstract:

A low profile balloon-on-a-wire catheter having a flexible elongate tubular member with proximal and distal extremities and with a lumen extending from the proximal extremity to the distal extremity. An inflatable balloon is mounted on the distal extremity of the flexible elongate tubular member. Communication is established between the lumen and the interior of the inflatable balloon. An inflation fitting is removably secured to the proximal extremity of the flexible elongate tubular member for supplying an inflation fluid to the lumen for inflating and deflating the balloon. The inflation fitting when removed provides a proximal extremity on the catheter which is free of obstructions so that another balloon catheter can be advanced over the proximal extremity of the flexible elongate tubular member.
