A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.

Modular aortic arch prosthetic assembly and method of use thereof

Methods for ameliorating stent graft migration and endoleak using treatment site-specific cell growth promoting compositions in combination with stent grafts are disclosed. Also disclosed are application of cell growth promoting compositions such as, but not limited to, autologous platelet gel compositions directly to treatment sites during or after stent graft implantation.

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.

Endolumenal prothesis and method of use in bifurcation regions of body lumens

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.

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.

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.
