Patent number: 9511451Abstract: A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.Type: GrantFiled: July 2, 2014Date of Patent: December 6, 2016Assignee: Abbott Cardiovascular System Inc.Inventors: Jeffrey W. Baxter, David Mackiewicz

Publication number: 20120010463Abstract: A retractor and a surgical tool are posittioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a dissection cradle that is resiliently supported along an axis skewed relative to the axis of the cannula. The dissection cradle, in operation, is extended to cradle the target vessel, and the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate a side branch for exposure to a surgical tool. The retractor includes a hollow support and a spray nozzle disposed in the distal end of the retractor to form an irrigation system and lens washer that can be selectively positioned to direct the spray of irrigation fluid at a remote surgical site or at an endoscopic lens.Type: ApplicationFiled: January 3, 2011Publication date: January 12, 2012Applicant: MAQUET CARDIOVASCULAR LLCInventors: Albert K.

Patent number: 7972265Abstract: A retractor and a surgical tool are positioned at the distal end of the cannula. A dissection cradle is located at the distal end of a distal portion of the retractor that is resiliently skewed relative to the cannula axis, and includes two substantially parallel, spaced legs with the retractor shaped in a loop therebetween. The procedure includes locating a vessel and side branch of interest and extending the retractor to retain the vessel in the dissection cradle to urge the vessel away from the axis of the cannula in order to isolate a side branch for exposure to the surgical tool.Type: GrantFiled: July 21, 2004Date of Patent: July 5, 2011Assignee: Maquet Cardiovascular, LLCInventors: Albert K.

Patent number: 7033357Abstract: An apparatus and method for minimally invasive surgery using a cutting tool with rotational cutting edges. The surgical instrument includes a tube having a distal end and a cutting edge at the distal end. A handle is attached to the proximal end of the tube. Within the tube is a shaft having a longitudinally extending blade at its distal end that is adjacent to the distal end of the tube. The blade is revolvable about the longitudinal axis of the instrument to provide rotational cutting action. One or both of the blade and the cutting edge on the tube can be electrically energized to provide for electrocauterization of the body tissue being cut.Type: GrantFiled: November 18, 2003Date of Patent: April 25, 2006Assignee: Origin Medsystems, Inc.Inventors: Jeffrey W.

Patent number: 6406425Abstract: A retractor and a surgical tool are positioned within a cannula, and a dissection cradle of the retractor is positioned at the distal end of the cannula. The retractor includes a first portion with an axis approximately parallel to the axis of the cannula and a second portion with an axis skewed relative to the axis of the cannula. The dissection cradle may include two substantially parallel, spaced legs with the retractor shaped in a loop between and in a plane skewed relative to the axes of the legs, and with the loop directed away from the surgical tool. Thus, in operation, when a surgeon locates a vessel and side branch of interest, the surgeon extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be fully extended to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to a surgical tool.Type: GrantFiled: August 8, 2000Date of Patent: June 18, 2002Assignee: Origin MedasystemsInventors: Albert K.
