Patent number: 8808299Abstract: Described herein are meniscus suture passers for repair of the meniscus of the knee. These devices are typically suture passers that may include an elongate body having a pair of arms. One or more of the arms may be angled or bent at the distal end region relative to the long axis of the device, forming a distal-facing opening that is configured to fit meniscus tissue. One or both arms may be movable in the axial direction (e.g., the direction of the long axis of the device). The devices typically include a tissue penetrating element housed within one of the arms but configured to extend across the distal opening between the arms. Thus, a suture may be passed from a first side of the tissue to a second side.Type: GrantFiled: April 30, 2013Date of Patent: August 19, 2014Assignee: Ceterix Orthopaedics, Inc.Inventors: Justin D.

Patent number: 8808325Abstract: A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.Type: GrantFiled: November 19, 2012Date of Patent: August 19, 2014Assignee: Ethicon Endo-Surgery, Inc.Inventors: Christopher J.

Patent number: 8795355Abstract: Apparatus for delivering a prosthetic heart valve into a patient by means that are less invasive than conventional open-chest, open-heart surgery. The prosthetic valve may be collapsed while in a delivery device. When the valve reaches the desired implant site in the patient, the valve can be released from the delivery device, which allows the valve to re-expand to the configuration in which it can function as a heart valve. For example, the delivery device may be constructed to facilitate delivery of the prosthetic valve into the patient via the apex of the patient's heart.Type: GrantFiled: July 30, 2013Date of Patent: August 5, 2014Assignee: St. Jude Medical, Inc.Inventor: Yousef F.

Patent number: 8795293Abstract: A device for pushing an anchor through a bore in a bone is provided with an elongated shaft, an anchor carrying assembly disposed at a distal end of the shaft for carrying an anchor, and a plunger disposed in the elongated shaft. The plunger is movable relative to the elongated shaft. First, threads are attached to the anchor. Then, the anchor is positioned in the anchor fastener, and the elongated shaft is placed next to the bore in the bone. Next, the plunger is inserted into the elongated shaft, and a force is exerted to on the plunger to move it in direction of the distal end of the elongated shaft such that a distal end of the plunger comes into contact with the anchor and pushes the anchor through the bore in the bone.Type: GrantFiled: September 29, 2008Date of Patent: August 5, 2014Assignee: Karl Storz GmbH & Co. KGInventors: Wolf Petersen, Thore Zantop

Patent number: 8795354Abstract: Disclosed replacement heart valves can be designed to be delivered to a native valve site while crimped on a delivery catheter. The crimped profile of the replacement valve can be minimized by, for example, separating a frame or stent structure from a leaflet structure, along the axial direction. Disclosed replacement valves can be transitioned from a delivery configuration, in which the crimped profile can be minimized, to an operating configuration. The replacement valve can be fully assembled in both the delivery and operating configurations. In some embodiments, the leaflets can be positioned outside of the stent in the delivery configuration, and positioned inside of the stent lumen in the operating configuration. Disclosed replacement valves can include a flexible sleeve coupling the leaflets to the stent and facilitating the transition to the operating configuration. Methods of implanting said replacement valves are also disclosed.Type: GrantFiled: March 4, 2011Date of Patent: August 5, 2014Assignee: Edwards Lifesciences CorporationInventors: Netanel Benichou, Stanton J.

Patent number: 8790358Abstract: Methods and apparatus for making an anastomotic connection between an opening at an end of a graft conduit and an aperture in a side wall of a body tissue conduit using a hollow connector assembly are provided, wherein the cross-sectional area of the anastomotic connection is larger than that of the graft conduit. The tissue about the opening is introduced about and retained by first members of a distal portion of the connector assembly held by a loading tool. A delivery tool then collapses a proximal portion defined by second members of the connector assembly and delivers the second members into the lumen of the body tissue conduit via the aperture. Upon inserting the second members into the body tissue conduit, the delivery tool is disemployed and the second members expand such that they press against the interior wall of the body tissue conduit and such that the first members are held within the aperture against a medial wall of the body tissue conduit.Type: GrantFiled: March 29, 2004Date of Patent: July 29, 2014Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Matthew Baker, Michael P.
