摘要： Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a delivery system for use in occluding an opening in the tissue of a body includes an actuation assembly operatively coupled to a medical device including an anchor portion and an occluder portion. The actuation assembly is configured to move the anchor portion between a deployed state and retracted state while the occluder portion maintains a deployed state. With this arrangement, the deployed occluder portion can be visualized via imaging at a preferred position prior to deploying the anchor portion of the medical device.

摘要： A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The closure device can include a body portion operatively associated with a first anchor and a second anchor. The body portion can include a plurality of segments defining a multi-cellular structure. The closure device can be configured to apply lateral force to tissue of the internal tissue opening to bring tissue together. The closure device can have a substantially flat aspect, and can include a member adapted to induce tissue growth. The anchors can extend from the body portion and return back to the body portion to define a closed periphery. The anchors can include undulations and can include multiple segments. A method of forming a closure device can include positioning a material on a working surface and cutting a closure device from the material.

摘要： Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.
