Abstract: An implantable medical device includes first and second material capture elements which are disposed in opposing orientations and have their narrow ends facing one another. The first and second material capture elements are connected by a flexible connector, which enables the implantable medical device to curve within a curved vessel of a patient. The flexible connector is either closed or has a lumen passing therethrough and includes a closure element for closing the lumen after deployment of the device within a patient. The structure enables the device to be positioned reliably within a curved vessel and benefits from the advantage of a double-ended device.

Abstract: An apparatus for operating on tissue includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body and includes an acoustic waveguide. The waveguide is configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm, and a clamp pad. The blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade and includes a coupling feature. The clamp pad is selectively attachable to the blade to acoustically isolate the clamp arm from the ultrasonic blade. The coupling feature of the clamp arm is configured to provide a snap fit between the clamp pad and the clamp arm and thereby permit manipulation of the clamp pad for removal of the clamp pad from the clamp arm.

Abstract: Methods for restoring blood flow in occluded blood vessels using an apparatus having a self-expandable distal segment that is pre-formed to assume a superimposed structure in an unconstrained condition but can be made to take on a volume-reduced form making it possible to introduce it with a microcatheter and a push wire arranged at the proximal end, with the distal segment in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments or struts. In a preferred embodiment, the distal segment has a tapering structure at its proximal end where the strings or filaments or struts converge at a connection point.

The method includes moving the anchor deployment component in a distal direction through the delivery guide, pushing the anchor out of the delivery guide, and delivering the anchor into tissue.

Abstract: In a surgical method for improving cardiac function, an implantable scaffold or valve support device is inserted inside a patient's heart and attached to the heart in a region adjacent to a natural mitral or other heart valve. The scaffold or valve support device defines an orifice and, after the attaching of the scaffold or valve support device to the heart, or temporary support while native valve leaflets and/or subvalvular structures are captured, a prosthetic or bio-prosthetic valve seated in the orifice, and the native valve may be retracted into the scaffold/replacement assembly to create a gasket for sealing the complex.

Abstract: Devices, systems and methods are disclosed for repairing soft tissue. The surgical system allows for the creation of tissue repair by grasping, aligning and sewing or fixing tissue. For example, this system may be used for clipping together excessive capsular tissue and reducing the overall capsular volume. The deployment device includes a central grasping mechanism and an outer clip delivery system. The clip embodiments may be single or multi-component (penetration and locking base components) that penetrate tissue layers and deploy or lock to clip the tissue together. An example of the system is used to reduce the joint capsule tissue laxity and reduces the potential for subluxation or dislocation of the joint by either restricting inferior laxity (anterior or posterior) and resolving or eliminating pathologic anterior or posterior translation.

Abstract: This is a laparoscopic instrument for facilitating intra-corporeal tying of knots. The shafts of two small diameter laparoscopic graspers are combined within a common external sheath. One grasper has a regular scissors handle, is stationary, and acts as a recipient grasper, while the other has no handle, but is rotatable and slidable, and acts as a donor grasper. It enables the head end of a suture to be actively passed from the jaws of the donor grasper to the jaws of the adjacent recipient grasper, after passing behind and around the tail strand, thus forming a knot. The current version of this instrument introduces two additional features, one being the passive production of the rotation by the straight sliding mechanism, the other being the use of free-wheeling levers allowing rotation of the shaft of the donor grasper, without rotating the attached levers in the slots.

Abstract: A method for accessing a mitral valve that includes forming an incision and inserting a first catheter comprising a lumen. The first catheter is adapted to be directed towards a left atrium and the first catheter has a working length of approximately 15 cm to approximately 52 cm. The method further includes utilizing a trocar in the first catheter to penetrate a pericardium and utilizing the trocar to penetrate the left atrium. The method further includes accessing the mitral valve from an antegrade direction.

Abstract: A platform of devices for removing obstructions and other objects within a blood vessel or other interior lumen of an animal is provided.

Abstract: A device for percutaneously delivering a stented prosthetic heart valve. The device includes an inner shaft assembly, a delivery sheath assembly, an outer stability tube, and a handle. The sheath assembly is slidably disposed over the inner shaft, and includes a capsule and a shaft. The capsule compressively contains the prosthesis over the inner shaft. The stability tube is slidably disposed over the delivery sheath, and includes a distal region configured to be radially expandable from a first shape having a first diameter to a second shape having a larger, second diameter. In a first delivery state, the distal region assumes the first shape, providing a low profile appropriate for traversing a patient's vasculature. In a second delivery state, the distal region has the expanded diameter second shape, sized to receive the capsule, such as when retracting the capsule to implant the prosthesis.

Abstract: This is a laparoscopic instrument intended to facilitate intra-corporeal tying of knots in a free strand of suture. The shafts of two small diameter laparoscopic graspers are combined within a common external sheath, and both are joined to a common handle to be used by one hand. One grasper has a regular scissors type of handle, is stationary, and acts as a recipient grasper, while the other grasper has no handle, but is able to rotate and to slide, and acts as a donor grasper. The instrument enables the head end of a suture to be actively passed from the donor grasper to the adjacent recipient grasper, passing behind and around the tail strand, forming a knot, in the same manner as in the tying of shoes-laces. The current instrument introduces a new mechanism, whereby the required rotational movements are automatically produced by the sliding motion.
