Patent number: 11141055Abstract: Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end.Type: GrantFiled: August 25, 2017Date of Patent: October 12, 2021Assignee: Maquet Cardiovascular LLCInventors: Liming Lau, Peter L. Callas, Michael C. Stewart, Geoffrey H. Willis, Ryan C. Abbott, Charles J. Adam, Kimberly D. Barkman, Kenny L. Dang, Joseph N. Lamberti, Arthur M. Lin, Ravinder D. Pamnani

Publication number: 20200237516Abstract: The devices and methods described herein may be used to restore left ventricular function to address mitral valve regurgitation. One variation of an implant comprises a plurality of tethered anchors and a plurality of force-distribution members slidably disposed on the tether between the anchors. One or more of the force-distribution members can comprise a bioabsorbable material. Methods comprise deploying the implant to cardiac tissue, cinching the implant to its hard stop (e.g., where further cinching does not cause further tissue tightening), providing a pre-selected amount of slack to the implant after it has been cinched to its hard stop configuration, and securing a lock member on the tether. Also disclosed herein are lock member deployment catheters that provide a pre-selected amount of tether slack as it secures a lock member on the tether.Type: ApplicationFiled: April 17, 2020Publication date: July 30, 2020Inventors: Russel SAMPSON, Jennifer HENDERSON, Jeff CLOSS, Joshua SAMPSON, Charles J.

Publication number: 20200099218Abstract: In some embodiments, a controller of an intelligent switch in a three-phase power distribution network is configured to serve as a sectionalizer. The controller preferably includes voltage restraint logic and count restraint logic to prevent opening of the switch in response to a detected fault unless the voltage and current drop below minimum threshold values. The controller preferably additionally includes inrush restraint logic that prevents detection of a fault in response to an inrush current spike that may occur, for example, on startup of an AC motor or when energizing a transformer. The controller preferably further includes close-on-fault detection logic that bypasses counting of fault/line clear events by the controller if the switch is closed on a fault.Type: ApplicationFiled: September 18, 2019Publication date: March 26, 2020Inventor: Charles J.

Patent number: 9636106Abstract: Devices and methods for locking and/or cutting tethers during a tissue modification procedure are described. In some variations, a tether may be used to tighten tissue by bringing two pieces or sections of the tissue together. The tether, which may be under tension, may be locked to maintain the tension, and excess tether may be severed, using one or more of the devices and/or methods. The devices and/or methods may be used, for example, in minimally invasive procedures.Type: GrantFiled: September 20, 2013Date of Patent: May 2, 2017Assignee: Ancora Heart, Inc.Inventors: Stephen C.

Patent number: 8906048Abstract: A vessel harvesting system that is suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The system includes a vessel harvesting tool with an elongated cannula and a plurality of surgical instruments therein for separating the target vessels from the surrounding tissue and side branches. The harvesting tool includes a modular handle unit with a base attached to the elongated cannula and a sled that can adapt the base to various types of vessel severing/securing tools, such as tissue welders, bipolar scissors, and bipolar bisectors. The handle unit may be relatively rigid and integrated with the various tool movement controls to facilitate one-handed operation by a user. A severing/securing tool rotation mechanism may be incorporated within the handle and operated by a thumbwheel or other such mechanism. The vessel harvesting system may also provide distal CO2 insufflation for enhanced maintenance of the operating cavity.Type: GrantFiled: February 14, 2011Date of Patent: December 9, 2014Assignee: MAQUET Cardiovascular LLCInventors: Arthur M. Lin, Joseph N. Lamberti, Kenny Dang, Michael C. Stewart, Charles J. Adam, Justin N. Williams

Patent number: 8833393Abstract: A hydraulic connector (14) attaches a valve chamber (16) to a flow pipe (P) using a hydraulic clamp (20) to grab the pipe (P) or a flange (F). The valve chamber (16) contains a primary hydraulic ram (26) to telescopically extend a primary seal (28) on the ram (26) to close or open the outlet ports (22) by moving the primary seal (28) to permit flow through valve up flow tubes (34) to a riser (R). Outlet ports (22) in the cap valve (12), or an intermittent pipe (18), permit unrestricted flow while the connector (14) is being installed.Type: GrantFiled: September 2, 2011Date of Patent: September 16, 2014Inventor: Charles J.

Publication number: 20130072758Abstract: 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 that can be skewed relative to the axis of the cannula. The dissection cradle is located at the distal end of the second portion of the retractor, and 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, a surgeon locates a vessel and side branch of interest and extends the retractor to cradle the vessel in the dissection cradle. Once cradled, the retractor may be deflected to urge the vessel away from the axis of the cannula to isolate the side branch for exposure to the surgical tool.Type: ApplicationFiled: March 9, 2012Publication date: March 21, 2013Applicant: MAQUET CARDIOVASCULAR LLCInventors: John P.
