Publication number: 20160100855Abstract: Over-the-wire self-sizing, self-centering valvulotomes sufficiently designed to cut valves through a wide range of vein diameters and adjust to the internal diameter of a vein as the valvulotome is being drawn through the vessel, and methods of use thereof during certain medical procedures that involve splitting valves, are disclosed herein. In an embodiment, an over-the-wire valvulotome includes a catheter having a proximal end, a distal end, and a longitudinal axis therebetween, wherein a first portion of a plurality of cutting tools engage the catheter at the distal end, and wherein an actuation mechanism engages the catheter at the proximal end; a retainer for temporarily shielding a second portion of the plurality of cutting tools, wherein the second portion includes cutting blades; and a sheath slidably moveable over the plurality of cutting blades, wherein the catheter and the retainer have internal diameters configured for passing over a guidewire.Type: ApplicationFiled: December 18, 2015Publication date: April 14, 2016Inventors: George W. LeMaitre, Ryan H. Connelly, Jahi C. Gist, Matthew G. Maher

Patent number: 7198397Abstract: The present invention is directed to methods of mounting a light source, such as, for example a high-efficiency, high-power solid state light source (e.g., a LED) within a handle of an endoscope. One of the methods of the present invention includes removing a portion of a package surrounding the light source to expose a light source chip, positioning the exposed light source adjacent to a chassis within the handle and in contact with an end of a light guide bundle, translating the light source with the exposed light source chip about the end of the light guide while measuring light output from an illumination (i.e., distal) end of the light guide bundle with a photodetector, and securing the exposed light source to the chassis at a position in which maximum light output is measured.Type: GrantFiled: September 16, 2005Date of Patent: April 3, 2007Assignee: Optim, Inc.Inventors: Hudson D. Bennett, Robert J. Krupa, William F. LaFlash, Matthew G. Maher, Thomas V. Root
