Patent number: 11103371Abstract: An implantable prosthesis designed to transition from a contracted state to an expanded state, including a continuous tubular helical winding and a plurality of bridges. The helical winding includes a plurality of circumferential sections spaced apart along a helical axis, each of the plurality of circumferential sections forming a non-orthogonal helical angle relative to the helical axis. The plurality of bridges connect adjacent circumferential sections, each having a length extending from a first end to a second end on a plane orthogonal to the helical axis, the length being equal to a circumferential offset between the adjacent circumferential sections in both the contracted state and the expanded state. The implantable prosthesis also includes a first annular ring orthogonal to the helical axis, and a first marker having a first end connected to the first annular ring, and a second end coupled to the first end of the helical winding.Type: GrantFiled: August 22, 2019Date of Patent: August 31, 2021Assignee: Angiomed GmbH & Co.

Publication number: 20150297872Abstract: A medical apparatus includes a catheter having an inflatable balloon at its distal end. The balloon defines at least two spaced larger diameter areas defining a valley therebetween and is adapted to be inserted in a non-inflated condition into a cavity of the human body such as the rectum, and when inflated, is adapted to cradle an organ such as the prostate located in a different body cavity. The balloon is symmetric about an axis defined by the catheter so that positioning issues are limited to axial positioning rather than rotational positioning. Because of the valley in the balloon, when the balloon is inflated, only a limited portion of the rectum is necessarily pushed into contact with the prostate, and thus, the radiation toxicity to the rectum is limited. Methods utilizing the medical apparatus are disclosed.Type: ApplicationFiled: October 25, 2013Publication date: October 22, 2015Applicant: EDGE MEDICAL, LLCInventors: Colin M. Carpenter, Gary A.

Patent number: 8821392Abstract: A surgical retention port particularly useful as an arthroscopic port for shoulder surgery is provided. The surgical retention port has a long pointed instrument such as a trocar or obturator, an inner cannula extending around the pointed instrument, a plurality of rotatable fingers coupled to the inner cannula, and an outer cannula extending around the inner cannula. In one embodiment of the invention, the inner cannula and long pointed instrument are keyed such that rotation of the long pointed instrument can effect rotational movement of the inner cannula. Rotation of the inner cannula in turn causes the rotation of the fingers from a first position where the fingers assume a collapsed configuration to a second position where the fingers assume an extended or open configuration.Type: GrantFiled: January 19, 2010Date of Patent: September 2, 2014Assignee: Joint Product Solutions, LLCInventors: Philip R. Lozman, Scott L. Jahrmarkt, Jerry S. Sher, Jeremy Louis Hemingway, David Charles Perdue, Paul J. Grata

Publication number: 20140214003Abstract: A system for treating a blood clot includes a microcatheter extending through an optional aspiration catheter, and a guidewire subassembly extending through and beyond the microcatheter, the guidewire assembly having a guidewire, an element coupled to and extending around a portion of the guidewire, and a balloon coupled to and extending around the element. The balloon includes or is coupled to a proximal seal in contact with the inner surface of the microcatheter and has at least one radially arranged pore. Infusate flows through the microcatheter into the element and between the element and the guidewire, and out and into the balloon to pressurize the balloon. The infusate escapes the balloon through the pores.Type: ApplicationFiled: July 14, 2011Publication date: July 31, 2014Inventors: Yi Yang, Scott L. Jahrmarkt, Michele Migliuolo, Juan Carlos Diaz
