The first fixation mechanism is configured to anchor the device to a first cardiac tissue. The device includes a second fixation mechanism disposed on a proximal end of the shaft. The second fixation mechanism is configured to anchor the device to a second cardiac tissue. The device includes an approximation mechanism connecting the first fixation mechanism and the second fixation mechanism, wherein the approximation mechanism causes the second fixation mechanism to move along the shaft toward the first fixation mechanism to approximate the first cardiac tissue and the second cardiac tissue.

Abstract: A device having an implantable body associated with at least two filaments or sutures and configured for use in soft tissue reconstructions is provided. One exemplary embodiment includes an implantable body, an adjustable filament loop for holding ligament grafts that is coupled to the body, and a shuttle suture removably coupled to the implantable body and configured for shuttling the body through at least a portion of a bone tunnel. The loop can be defined by a self-locking knot, and one or more loop-adjusting limbs can extend from the knot, with a portion of the limb(s) also extending into a hollow portion of the shuttle suture. In some embodiments having two adjustable limbs, an intermediate portion of each limb can be the portions disposed in respective hollow portions of the shuttle suture. Other configurations of devices and systems, as well as methods for performing ACL repairs, are also provided.

Abstract: Embodiments of the present disclosure are directed to stents, valved-stents, and associated methods and systems for their delivery via minimally-invasive surgery.

Abstract: A surgical cutting instrument for transapical aortic valve resection includes a cutting unit arranged on the distal end of a tool shaft and at least one mechanical cutting element for making a circular incision. The at least one cutting element can be adapted, in particular continuously adapted to different aortic diameters by means of a radially movable actuating mechanism.

Abstract: A burr hole cover is configured to be recessed in a burr hole formed in a patient and includes a base and a cap provided with complementary features to allow a portion of a medical device, such as a brain lead, to be situated in the burr hole cover and then secured by rotation of the cap relative to the base. The features include channels on the base and matching cut-outs on the cap, and slots and locking pockets on the base that are configured to be aligned with locking tabs and locking protrusions on the cap. Because the burr hole cover is recessed in the burr hole, the medical device can extend proximally of the burr hole at the level of the cranium. A bottom surface of the cap may be provided with guides for the lead extending distally in towards the brain.

Abstract: A catheter inner assembly includes a receptacle with an interior contour configured to mate with a head and neck contour of a holding member of an implantable medical device; and a laterally facing opening of the receptacle has a profile matching a longitudinal profile of the head and neck. Thus, the opening allows only a properly oriented passage of the holding member therethrough, the passage being without deformation of holding member or opening. The inner assembly further includes a lock and release member useful for securing the device to the catheter, when the holding member has been passed through the receptacle's opening to mate with the receptacle's interior contour. The lock and release member may include an arcuate sidewall moveable between a first location, at which the sidewall overlays the laterally facing opening, and a second location, at which the sidewall is located proximal to the opening.

Abstract: The present invention relates to an occluder, comprising a meshed occlusion body provided with a cavity, and a proximal hub, as well as a locking member and a stopping member both of which are located in the cavity. The distal end of the locking member is connected to the distal end of the occlusion body. The stopping member is disposed at the proximal end of the locking member. The proximal occluder head is provided with a locking hole in communication with the cavity. An occlusion device comprises the occluder, a hollow delivery' mechanism and a traction member. The distal end of the traction member is detachably connected to the proximal end of the locking member of the occluder after extending through the distal end of the delivery' mechanism. The occlusion device has a simple locking structure, and simplifies the manufacturing process and the locking operation.

Abstract: Disclosed herein are devices for improving coaption of the mitral valve leaflets to reduce or eliminate mitral valve regurgitation. The devices may be used to perform mitral valve annuloplasty, or to serve as a docking station for a transcatheter prosthetic heart valve. The various embodiments of devices are configured for percutaneous and, in some cases, transvascular delivery. Delivery systems useful for routing the devices to the mitral valve are also disclosed, including catheters, balloons and/or mechanical expansion systems. The devices themselves include at least one tissue penetrating member. Methods of delivery include partially embedding the devices in the mitral valve annulus via at least one tissue penetrating member. Tissue penetrating members may be embedded into the tissue in a simultaneous or a nearly simultaneous fashion. Upon embedding, the devices employ various expansion and/or contraction features to adjust the mitral valve diameter.

Abstract: A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may treat conditions like a stroke by removing a clot from a blood vessel and/or reopen the vessel. The device may have a plurality of engaging elements, wires that can link at least two engaging elements, a central wire, and proximal control element. The positions of the engaging elements and the distance there between can be adjusted to ensure the engagement of the clot or occlusion.

Abstract: A helical stent is provided that is wound in a zig-zag pattern along a pitch angle with respect to a plane transverse to the axis of the stent. A bisecting line extending through a bend and between two adjacent angular struts is also angled with respect to the longitudinal axis of the stent.

Abstract: A polymeric, surgical clip is provided for clamping a blood vessel between two legs. A hook section of the clip comprises, in some embodiments, a sharpened forward edge and/or a sharpened rearward edge for penetrating connective tissue adjacent a vessel before closing the surgical about a blood vessel. The upper leg of the surgical clip may comprise an oblique flank for disposing over the one or more edge of the hook section, preventing damage to soft connective tissue surrounding the surgical clip postoperatively.

Abstract: According to aspects of the present disclosure, a retrieval catheter assembly for retrieving an intragastric balloon may include a tubular member configured to pass through a wall of the intragastric balloon. The retrieval catheter assembly may also include a retrieval member coupled to the tubular member and movable between an undeployed configuration and a deployed configuration. In the undeployed configuration the retrieval member may be substantially aligned with the tubular member. In the deployed configuration at least a portion of the retrieval member may diverge from the tubular member and may be configured to engage the wall of the intragastric balloon.
