Publication number: 20220071656Abstract: An atherectomy catheter for use in a vessel includes an elongate catheter body and an annular cutter. The elongate catheter body includes a fixed jog section with a pre-set curvature and a flexible section that has a greater flexibility than a remainder of the elongate catheter body. The fixed jog section and flexible section are formed of a frame including a plurality of circumferential slits therein. Also described herein is an atherectomy catheter for use in a vessel includes an elongate catheter body, an annular cutter, and an s-shaped curved portion in the elongate catheter body. The curved portion includes a frame having a longitudinal proximal spine and a longitudinal distal spine. The longitudinal proximal spine is positioned approximately 180 degrees away from the longitudinal distal spine.Type: ApplicationFiled: November 18, 2021Publication date: March 10, 2022Inventors: Himanshu N.

Patent number: 8579968Abstract: Annuloplasty rings reduce or eliminate tricuspid regurgitation and/or tricuspid annulus dilation. An adjustable annuloplasty device includes a ring body having a first free end and a second free end. The ring body includes a shape memory material to provide a shape change to the adjustable annuloplasty device upon activation. The ring body includes a first segment including the first free end and following a curved path corresponding to an anterior leaflet region of a tricuspid annulus, a second segment following a curved path corresponding to a posterior leaflet region of the tricuspid annulus, and a third segment including the second free end and at least partially following a linear path corresponding to a portion of a septal leaflet region of the tricuspid annulus. Activation of the shape memory material changes a dimension of the adjustable annuloplasty device.Type: GrantFiled: May 19, 2011Date of Patent: November 12, 2013Assignee: MiCardia CorporationInventors: Frank Shannon, Samuel M. Shaolian, Brian C. Gray, Vincent Yeh

Publication number: 20070208111Abstract: The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.Type: ApplicationFiled: March 3, 2006Publication date: September 6, 2007Inventors: Haixin Yang, Pedro Jimenez, Cherng Wang, Christopher Roach, John Pepin, Michael Barker, Vincent Yeh
