Patent number: 8308708Abstract: A catheter-based deployment system for deploying cellular material (22) into the heart muscle (25). The deployment system includes a guiding catheter (19) and a needle assembly (31) capable of sliding within the guiding catheter. The needle assembly (31) terminates in a tip (34) having at least one side with an opening (43) in communication with a lumen (20) disposed within the needle assembly (31). Once the guiding catheter (19) is positioned, the needle assembly (31) is advanced until the tip (34) penetrates the muscle wall (25).

Patent number: 6733519Abstract: 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.Type: GrantFiled: November 28, 2001Date of Patent: May 11, 2004Assignee: Medtronic, AveInventors: Robert D.

Patent number: 6602271Abstract: 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.Type: GrantFiled: December 12, 2000Date of Patent: August 5, 2003Assignee: Medtronic Ave, Inc.Inventors: Bruce Adams, Ahmed Malek, Jerry R.

Publication number: 20030028240Abstract: A stent-graft assembly having a thin-walled membrane and method of preparing the same are disclosed. In a first embodiment, the assembly comprises a stent, a coating and a porous membrane, wherein the membrane is less than 0.040 inch thick or less. Portions of the coating extend into the pores of the thin membrane to sealingly engage the membrane to achieve secure adhesion. In a second embodiment the coating and thin membrane bond to form a homogenous structure. In an alternative embodiment, the assembly comprises an inner and outer thin membrane bound to one another through the interstices of the support member and a coating at the proximal and distal regions. In any of the foregoing embodiments, the proximal and distal regions of the stent-graft assembly may comprise an additional coating, whereby layers of material are sealed, thereby minimizing thrombogenic potential of free ends of the assembly.Type: ApplicationFiled: October 1, 2002Publication date: February 6, 2003Inventors: John E.

Publication number: 20020065548Abstract: A profiled stent for supporting and maintaining the patency of lumens in living tissue. The profiled stent includes a plurality of support members, each of the support members having a first side, a second side positioned opposite the first side, a third side adjoining the first and second sides, a fourth side positioned opposite the third side adjoining the first and second sides. Four corners are defined by the adjoining first, second, third, and fourth sides. At least one of the support members of the stent is profiled such that the four corners of that support member are round, while the first and second sides are substantially flat or, stated differently, exhibit substantially similar radii of curvature.Type: ApplicationFiled: December 20, 2001Publication date: May 30, 2002Inventors: Matthew J.

Patent number: 6309402Abstract: A encapsulated stent device for implantation within the vascular system includes a balloon of a balloon catheter formed around and adhered to a wire-like stent so that the outer surface of the device is more regular for delivery through the vascular system without an exterior sheath. The encapsulation securely anchors the stent to the balloon and maintains a low profile for negotiation of tortuous and narrowed vessels. Encapsulation requires placement of the stent over the balloon, placement of a sheath over the stent on the balloon, heating and preferably pressurization of the balloon to cause it to expand around the stent within the sheath, and cooling while preferably maintaining pressure to cause the balloon to adhere to the stent and to set the shape of the expanded balloon. Retainers may be placed at the distal and/or proximal ends of the stent during the encapsulation process, or the balloon material may expand to form retainers.Type: GrantFiled: November 10, 1998Date of Patent: October 30, 2001Assignee: Medtronic Ave, Inc.Inventors: Bradley A. Jendersee, Robert D. Lashinski, Michael D. Bonneau

Patent number: 6183507Abstract: A stent for helping to hold open a lumen in a tubular body structure has at least one axial portion (preferably an axial end portion) that stents the surrounding portion of the tubular body structure to a lesser degree than another axial portion of the stent. For example, the stent portion that stents to a lesser degree may be circumferentially weaker than the other stent portion, or it may recoil more than the other stent portion after the stent is applied by being circumferentially expanded and then released.Type: GrantFiled: December 24, 1998Date of Patent: February 6, 2001Assignee: Medtronic Ave, Inc.Inventors: Robert D.
