Publication number: 20150066134Abstract: A method of percutaneously delivering a multi-layered stent assembly to a desired implantation location of a patient including the steps of radially compressing a multi-layered stent assembly to a compressed size for implantation in a patient, the multi-layered stent assembly including a first stent, a second stent coaxially positioned within at least a portion of a length of the first stent, and a valve, wherein the first stent comprises at least one different material property than the second stent. The method further includes delivering the multi-layered stent assembly to the desired implantation location of the patient using a delivery system and substantially simultaneously expanding the first stent and the second stent of the multi-layered stent assembly at the desired implantation location to a radially expanded size that is larger than the compressed size.Type: ApplicationFiled: November 10, 2014Publication date: March 5, 2015Inventors: Philipp Bonhoeffer, Silvia Schievano, Timothy R.

Patent number: 8961593Abstract: A heart valve that can be expanded following its implantation in a patient, such as to accommodate the growth of a patient and the corresponding growth of the area where the valve is implanted, and to minimize paravalvular leakage. In one aspect, the invention may maximize the orifice size of the surgical valve. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. In one aspect of the invention, the valve may be adapted to accommodate growth of a patient to address limitation on bioprosthetic valve lifespans.Type: GrantFiled: December 5, 2013Date of Patent: February 24, 2015Assignee: Medtronic, Inc.Inventors: Philipp Bonhoeffer, Timothy R.

Patent number: 8858619Abstract: A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.Type: GrantFiled: May 12, 2006Date of Patent: October 14, 2014Assignee: Medtronic, Inc.Inventors: Allen J. Tower, Philipp Bonhoeffer, Michael L. Martin
