Publication number: 20240081886Abstract: A vapor delivery needle and method is provided that is adapted for treating prostate cancer. The energy delivery probe can apply condensable vapor energy to tissue, such as a peripheral zone tissue in a human prostate. In one method, a needle is introduced into peripheral zone tissue of a human prostate, and vapor media is delivered through the needle to ablate peripheral zone tissue without ablating non-peripheral zone tissue. Systems for treating prostate cancer with vapor therapy are also provided.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Michael HOEY, Grant MAUCH, Mark SCHROM

Patent number: 8597238Abstract: An enhanced cross stream mechanical thrombectomy catheter having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. A multidirectional fluid jet emanator positioned within the distal catheter lumen comprises high velocity fluid jets which produce jet flow that is directed toward distal and proximal ends of the catheter. Jet flow directed toward the proximal end provides a region of low pressure near an inflow orifice which acts to pull thrombotic particulate from the vasculature. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from one side of the catheter distal end urges the opposing non-orificed side of the catheter distal end toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall.Type: GrantFiled: April 23, 2012Date of Patent: December 3, 2013Assignee: MEDRAD, Inc.Inventors: Michael J.

Publication number: 20120239065Abstract: An enhanced cross stream mechanical thrombectomy catheter with backloading manifold having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from the one side of the distal end of the catheter resultantly urges the distal end of the catheter and thus the opposing non-orif iced side of the distal end of the catheter toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall. Features of the invention include a geometrically configured insert to facilitate the backloading or exchange of guidewires.Type: ApplicationFiled: April 23, 2012Publication date: September 20, 2012Inventors: Michael J.

Publication number: 20070197956Abstract: A dual lumen aspiration catheter system with an aspiration catheter, a hub and a flexible strain relief, and a suction assembly. The aspiration catheter includes multiple successively connected flexible tubular components each increasing in relative flexibility in the distal direction, the most proximal tubular component connectingly extending from the hub and through the flexible strain relief. The tubular components of the aspiration catheter include, in order proximally to distally, a composite tube, an intermediate tube, a dual lumen tube, and a flexible tip tube. The dual lumen tube includes eccentrically co-located large and small tubular portions forming eccentrically co-located large and small lumens to provide a minimum cross section. The distal end of the dual lumen tube includes a convex beveled edge. The convex beveled edge and the flexible tip tube singly or jointly inflict minimal traumatic contact with a vessel wall when urged along a tortuous vascular path.Type: ApplicationFiled: February 23, 2006Publication date: August 23, 2007Inventors: Hieu Le, Michael Schrom, Diana Wong, Kyle Matson, Dean Swanson, Kathleen Grant, James Klee

Publication number: 20060064123Abstract: A rapid exchange fluid jet thrombectomy device having a streamlined manifold and a catheter having multiple tubular segments where each tubular segment increases in flexibility in a distal direction. Torque response and pushability is enhanced by the arrangement of a proximally located tubular segment composed of a polymer-jacketed spiral metal tube in combination with an intermediate tubular section and a distal tubular section each having different degrees of flexibility. A guidewire tube exit region is provided where the intermediate tubular section joins the distal tubular section for over-the-wire guidewire usage. The polymer-jacketed spiral metal tube can extend along a partial or full length of the catheter and can include a basic continuous spiral cut which has regions of constant pitch or which has progressively increasing pitch, or in the alternative, can include an interlocking spiral cut having constant pitch regions or progressively decreasing pitch.Type: ApplicationFiled: April 1, 2005Publication date: March 23, 2006Inventors: Michael Bonnette, Michael Schrom, Hieu Le

Publication number: 20050027341Abstract: An implantable medical lead and lead body, method of manufacturing the same, and a system and method for stimulating a portion of a body are disclosed. A lead body assembly is formed by preparing a first layer unitary body comprising a first plurality of conductors wound in a first direction. An inner layer of extrusion material is placed on the first layer unitary body. A second plurality of conductors coated with extrusion material is placed on the inner layer. The second plurality of conductors is wound in a second opposite direction. An outer layer of extrusion material is placed over the second plurality of conductors. Heat shrink tubing is placed over the assembly. The extrusion material is heated and melted and compressed around the conductors. When the heat shrink tubing is removed, the solidified extrusion material forms a protective wall that encapsulates the conductors in the lead body.Type: ApplicationFiled: July 29, 2003Publication date: February 3, 2005Applicant: MICRONET MEDICAL, INC.Inventors: Michael Schrom, Charles Lehman, Mark Schrom
