Patent number: 8968394Abstract: An improved holder and storage system for a tissue-type prosthetic mitral heart valve that constricts the commissure posts of the valve and prevents suture looping. A rod axially movable relative to the holder tensions lengths of attachment sutures that extend between the commissure post tips to create a tent and flex the tips inward, thus helping to prevent looping of any of an array of pre-implanted sutures around the leading tips during delivery of the valve. The holder has a safety mechanism that prevents valve delivery before the rod is deployed. One embodiment automatically deploys the rod upon opening a storage jar. One embodiment permits a delivery handle to directly deploy the rod, while another uses a separate worm screw and coupling. A holder clip that attaches to a packaging sleeve may be formed of flexible members meshed together from which the heart valve and holder are easily pulled free to eliminate a step of decoupling the clip from the sleeve.Type: GrantFiled: May 11, 2012Date of Patent: March 3, 2015Assignee: Edwards Lifesciences CorporationInventors: Michael C. Murad, Emil Karapetian, W. Vaso Adzich

Publication number: 20150007630Abstract: An exemplary system for crimping a prosthetic valve comprises a radially expandable and compressible prosthetic valve, a crimping device positioned around the valve and configured to reduce the diameter of the valve to a delivery configuration, and a sterile package enclosing the valve and the crimping device. The valve can be pre-assembled in a partially crimped configuration within the crimping device. After removing the sterile packaging, the crimping device can be used to crimp the valve from the partially crimped configuration to the delivery configuration, such as by twisting a knob on the crimping device. The system can further comprise at least a portion of a delivery catheter within the sterile package, wherein the valve is pre-mounted on or adjacent to an inflatable balloon of the delivery catheter, such that the valve can be crimped onto the delivery catheter using the crimping device.Type: ApplicationFiled: February 14, 2014Publication date: January 8, 2015Applicant: Edwards Lifesciences CorporationInventors: David Maimon, Ron Sharoni, Tamir S.

Publication number: 20140364876Abstract: In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.Type: ApplicationFiled: July 31, 2014Publication date: December 11, 2014Inventors: George W. White, David Gregoire, David Aldridge, Edward E. Dolendo, Emil Karapetian, Norman S. Gordon, Tri Nguyen

Patent number: 8840664Abstract: Apparatus and methods for securing heart valve repair or replacement prostheses in or near the heart. The apparatus and methods are particularly well suited for traditional surgery or minimally invasive surgery. The invention secures a heart valve repair or replacement prosthesis in place while lowering surgical exposure. The invention improves the ease of implantation because it reduces the number of surgical knots a clinician would normally tie in the limited space in and around the heart.Type: GrantFiled: June 14, 2012Date of Patent: September 23, 2014Assignee: Edwards Lifesciences CorporationInventors: Emil Karapetian, Chris J. Okos, Matthew T. Winston

Publication number: 20140100601Abstract: A surgical instrument can comprise an elongate tube including a camming rod and an actuation mechanism operably connected to the camming rod; a first jaw spine having a first cam slot; and a second jaw spine having a second cam slot, the second jaw spine pivotally connected to the first jaw spine at a common pivot pin connected to the elongate tube. A camming pin rides along first and second interior camming surfaces and closes the jaw spines when the camming rod moves proximally. When the camming rod moves distally, a camming projection rides on first and second exterior camming surfaces on proximal sides of the first and second jaw spines and opens the jaw spines. One camming surface on each jaw spine facilitates closing the jaw spines while the other camming surface on each jaw spine facilitates opening the jaw spines. These two camming surfaces can be widely separated.Type: ApplicationFiled: September 30, 2013Publication date: April 10, 2014Applicant: Applied Medical Resources CorporationInventors: Russell E. Ahlberg, Scott V. Taylor, David T. Okihisa, Gregory I. Bak-Boychuk, Emil Karapetian, John Stout

Publication number: 20130197575Abstract: A suture anchor apparatus and method for anchoring a length of suture with respect to a target tissue has an anchor body with an anchoring structure for fixing the anchor body within the target tissue and a suture locking member. The moveable suture locking member is disposed at least partially within an anchor body lumen while a portion of the length of suture is looped around the suture locking member such that a first and second limb of suture exits the lumen. A suture locking member includes at least two elongate arms, and each arm has an extension dimension respectively, such that the first arm extension dimension is substantially greater than the second arm extension dimension.Type: ApplicationFiled: January 27, 2012Publication date: August 1, 2013Inventors: Emil Karapetian, Steven Wolf

Publication number: 20130197577Abstract: A suture anchor device and method for attaching soft tissue to bone includes an anchor body and a suture locking wedge movably disposed within the anchor body. Tension applied to one side of a suture causes the suture locking wedge to move in a translational and angular dimension to a position which compresses the suture, thereby locking the suture in the anchor. The anchor body includes tracks or slots which guide the suture locking wedge from the unlocked open configuration to the locked configuration.Type: ApplicationFiled: January 27, 2012Publication date: August 1, 2013Inventors: Steven Wolf, Emil Karapetian, George W. White, David Gregoire

The suture locking wedge includes lateral portions which engage slots or windows in the anchor body. Tension applied to one limb of a suture causes the suture locking wedge to translate and rotate to a position which compresses the suture, thereby locking the suture in the anchor.Type: ApplicationFiled: January 27, 2012Publication date: August 1, 2013Inventors: Pablo Catania, Steven Wolf, Emil Karapetian, George W.
