Publication number: 20070198006Abstract: A microwave antenna having a curved configuration is described herein. The antenna portion is formed into various shapes whereby the antenna substantially encloses, by a partial or complete loop or enclosure, at least a majority of the tissue to be irradiated. When microwave energy is delivered through the antenna, the curved configuration forms an ablation field or region defined by the curved antenna and any tissue enclosed within the ablation region becomes irradiated by the microwave energy. The microwave antenna is deployed through one of several methods, and multiple curved antennas can be used in conjunction with one another. Moreover, RF energy can also be used at the distal tip of the antenna to provide a cutting tip for the antenna during deployment in tissue.Type: ApplicationFiled: March 5, 2007Publication date: August 23, 2007Inventors: Mani Prakash, Francesca Rossetto, Steven Kim, Brian Shiu, Thomas Fogarty, Sascha Zarins

Publication number: 20070061005Abstract: The present invention relates to devices and methods for the treatment of diseases in the vasculature, and more specifically, devices and methods for treatment of aneurysms found in blood vessels. In a first embodiment of the present invention, a two part prostheses, where one part is an expandable sponge structure and the other part is an expandable tubular mesh structure, is provided. In the first embodiment, the expandable sponge structure is intended to fill the aneurysm cavity to prevent further dilatation of the vessel wall by creating a buffer or barrier between the pressurized pulsating blood flow and the thinning vessel wall. In the first embodiment, the expandable tubular mesh structure is placed across the aneurysm, contacting the inner wall of healthy vessel proximal and distal to the aneurysm.Type: ApplicationFiled: November 2, 2006Publication date: March 15, 2007Inventors: Steven Kim, Brian Shiu, Nell Holmgren

Publication number: 20060265045Abstract: A method of deploying a prosthesis includes engaging a hub assembly of a handle to a threaded outer surface of a slide shaft of the handle; rotating the hub assembly to cause axial translation of the hub assembly and a sheath coupled to the hub assembly to initiate deployment of the prosthesis; disengaging the hub assembly from the threaded outer surface by pivoting a thread tooth of the hub assembly out of threaded engagement with the threaded outer surface; and sliding the hub assembly on the slide shaft to further retract the sheath and complete deployment of the prosthesis.Type: ApplicationFiled: July 27, 2006Publication date: November 23, 2006Applicant: Medtronic Vascular, Inc.Inventors: Brian Shiu, Ari Gershman, Burt Goodson, Paul Weber, Richard Repp, David Jensen

Patent number: 7105016Abstract: A delivery system includes a sheath and a handle. The handle includes: a slide shaft having a threaded outer surface; and a hub assembly coupled to the sheath. The hub assembly includes: an inner slider having a thread tooth pivot support; a thread tooth pivotably mounted to the thread tooth pivot support; and a sleeve having a thread tooth press member pressing on the thread tooth, where motion of the sleeve relative to the inner slider pivots the thread tooth on the thread tooth pivot support to engage and disengage the hub assembly with the threaded outer surface.Type: GrantFiled: January 5, 2004Date of Patent: September 12, 2006Assignee: Medtronic Vascular, Inc.Inventors: Brian Shiu, Ari Gershman, Burt Goodson, Paul L. Weber, Richard E. Repp, David F. Jensen

Patent number: 6911039Abstract: A method of deploying a prosthesis includes restraining the prosthesis within a distal end of a sheath. A slide ring of a handle is rotated to initiate retraction of the sheath. In this manner, the prosthesis is initially very gradually released. The slide ring is then slid to complete retraction of the sheath and to deploy the prosthesis. In this manner, the sheath is easily and quickly retracted thus rapidly completing deployment of the prosthesis. Rapid deployment of the prosthesis facilitates faster procedure times, thus minimizing the period of time during which blood flow is occluded.Type: GrantFiled: April 23, 2002Date of Patent: June 28, 2005Assignee: Medtronic Vascular, Inc.Inventors: Brian Shiu, Ari Gershman, Burt Goodson

Publication number: 20040148011Abstract: A flexible connecting bar mounted on an endoluminal stent graft eliminates art problems associated with preferential bending. The flexible connecting bar has a length, and includes a plurality of articulation points along the length. The plurality of articulation points permits the flexible connecting bar to bend at least into and out of a plane.Type: ApplicationFiled: January 24, 2003Publication date: July 29, 2004Inventors: Brian Shiu, Nickola Lewis, Ari Gershman, Feliks Basin

Patent number: 6676699Abstract: A bifurcated endoluminal prosthesis is provided that includes a valve or gate in one of the bifurcated branches. The valve or gate prevents flow of blood through the branch when it is closed and permits the flow of blood when it is open. In one variation, the valve comprises a spring member attached to a graft material substantially impermeable to the flow of blood. The spring member holds the graft material over the opening that forms a lumen in the bifurcated portion. The spring member may be flipped from a closed position in which it is initially deployed, to an open position whereby the graft material forms an opening continuous with lumen in the bifurcated portion permitting the flow of blood therethrough. The invention may be used in bifurcated or branched tubular grafts for endoluminal placement within a body lumen, including blood vessels, and for the treatment of abdominal and other aneurysms.Type: GrantFiled: April 26, 2002Date of Patent: January 13, 2004Assignee: Medtronic Ave, IncInventor: Brian Shiu
