20080208191 | Unitary blood vessel dissector and harvester device - A unitary dissector/harvester device for dissecting and harvesting a vessel has an elongated dissector tool for insertion into a body having the vessel to be harvested and a harvester tool axially positioned within the dissector tool. | 08-28-2008 |
20080208192 | Ring vessel dissector/harvester device - A ring dissector/harvester device for dissecting and harvesting a vessel has a capture tool that is co-axially positioned around the vessel to at least temporarily hold the vessel. A sealing tool is coaxially positioned within the capture tool and is axially movable with respect to the capture tool. The sealing tool and the capture tool are engaged to cauterize a branch from the vessel and to seal the cauterized branch and vessel. | 08-28-2008 |
20080208227 | Self-contained dissector/harvester device - A self-contained device for dissecting and/or harvesting a vessel includes a self-contained light source and a self-contained imaging system positioned within the sheath. | 08-28-2008 |
20080228207 | Semi-automatic power assist for endoscopic vein dissector - An endoscopic vein dissector for removing a vein from a living body comprises a dissector tip adapted to penetrate between the vein and surrounding tissue. A handle is provided for manipulation by a device operator to guide the tip through an incision in the living body to the vicinity of the vein. A longitudinal rod is mounted between the dissector tip and handle such that the tip is movable with respect to the handle between a retracted position and an extended position. A driver applies motive power to move the dissector tip from the retracted position to the extended position. A control element is adapted to be activated by the device operator to assist in the desired penetration between the vein and the surrounding tissue. | 09-18-2008 |
20080255407 | Bi-directional system for dissecting and harvesting vessels - A method and apparatus for bi-directionally dissecting and harvesting a vessel includes a dissector device that is at least temporarily secured to a harvester device. | 10-16-2008 |
20080255589 | Multi-function clipping and harvesting device - A multi-function minimally invasive vessel clipping and harvesting device includes at least two clipping devices positioned to advance surgical clips onto a tissue, and a severing device positioned to sever the tissue between the clips. | 10-16-2008 |
20090112053 | Blood Vessel Preparation and Preservation Kit - A vessel preparation and preservation kit supports a blood vessel during processing for use in bypass graft surgery. The device comprises a clamshell base having first and second trays latchable in a closed condition and pivotable to an open condition. The first tray has a series of open slots on an interior surface, wherein each slot extends substantially transverse to the longitudinal axis of the clamshell base. A first fixture has a first plate positionable in any selected one of the slots, a first fitting for holding a first end of the blood vessel, and a fluid supply needle for inserting into the first end of the blood vessel. A second fixture has a second plate positionable in any selected one of the slots a predetermined distance from the first fixture and having a second fitting for holding a second end of the blood vessel. A liquid-retaining foam is mounted in the second tray to immerse the prepared blood vessel in liquid to preserve it by putting the trays in the closed condition. | 04-30-2009 |
20110230711 | Endoscopic Surgical Instrument - An endoscopic surgical instrument includes a wiping section that is provided at a tip part of a insertion section and is pivoted to wipe off extraneous matter adhering to an observation surface provided at a tip part of an endoscope inserted through a grip section and the insertion section, an axial member that is inserted through the insertion section and is connected to the wiping section and an operation section that is provided over a whole circumference of a top end of the grip section in a circumferential direction in a longitudinal direction of the grip section, is connected to the axial member, and operates the wiping section through the axial member. A center axis of operation section is coaxial to an axis of endoscope when the endoscope inserted through the grip section and the insertion section. | 09-22-2011 |
20110230881 | Endoscopic Surgical Instrument - An endoscopic surgical instrument includes an insertion section which is inserted into a body cavity, and a surgical section which is disposed on a tip of the insertion section and treats an object. The surgical section includes a body section, and a first electrode, a second electrode, and a third electrode which are disposed on the body section. The surgical section coagulates and cuts the object by using a combination of not less than two of the first electrode, the second electrode, and the third electrode. | 09-22-2011 |
20130211197 | Endoscopic Surgical Instrument - An endoscopic surgical instrument includes a wiping section that is provided at a tip part of an insertion section and is pivoted to wipe off extraneous matter adhering to an observation surface provided at a tip part of a lens the endoscope through a grip section and the insertion section. An axial member is inserted through the insertion section and is connected to the wiping section. An operation section is provided over a whole circumference of a tip end of the grip section in a longitudinal direction of the grip section, is connected to the axial member, and operates the wiping section through the axial member. A center axis of the operation section is coaxial to a center axis of an endoscope when the endoscope is inserted through the grip section and the insertion section. | 08-15-2013 |
