A medical device is disclosed that can include a first atrial anchor, a first delivery shaft linked to the first atrial anchor, wherein the first delivery shaft is adapted to move the first atrial anchor, a second atrial anchor, a second delivery shaft linked to the second atrial anchor, wherein the second delivery shaft is adapted to move the second atrial anchor, and a biasing member linking either (i) the first atrial anchor to the first delivery shaft or (ii) the second atrial anchor to the second delivery shaft. The medical device can include an insulation material coupled to one or more of the first or second atrial anchors, or the first or second delivery shaft. A method for treating an internal tissue opening is also disclosed wherein a first and second electrode can be operated between unipolar and bipolar modes to initiate tissue damage, thereby inducing tissue regrowth.

The present invention includes systems, methods, and apparatus configured to close an internal tissue opening, such as an internal tissue opening cased by an atrial septal defect including a patent foramen ovale defect, ventricular septal defect, patent ductus arterosus defect, or the like. For example, a closure device includes a right anchor cooperatively coupled with a left anchor, where the right anchor and left anchor are configured to be positioned about the internal tissue opening. The left and/or right anchor are configured to close the internal tissue opening in one instance, and to provide tissue stimulating or growth-encouraging substances at the tissue opening. Additional aspects of the invention relate to shape, formation, positioning, and detachment of the closure device about the internal tissue opening.

A medical system for use in reducing the size of an internal tissue opening is disclosed. The medical system can include a patent foramen ovale or PFO closure device and a delivery device therefore. The PFO closure device can include left and right anchors connected by a stem. The delivery device is configured to selectively deploy at least one of the right or left anchors of PFO closure device so as to enable a practitioner to adjust PFO closure device during the positioning procedure. In one embodiment, the delivery device includes a filament operating shaft linked to the right anchor by one or more filaments. A practitioner can move the filament operating shaft to selectively deploy and retract the right anchor during positioning of the PFO closure device. Furthermore, the delivery device comprises a tether shaft for coupling delivery device to PFO closure device. In one embodiment, the tether shaft comprises a first portion and a flexible second portion, wherein the flexible second portion is at a distal end of the tether shaft.

Several embodiments are set forth of devices, systems and methods for modifying an atrial appendage such as a left atrial appendage (LAA). In one embodiment, a device includes a body that is collapsible and self-expanding. The body includes a textured surface with protruding portions and recessed portions. The body may be formed of a reticulated foam material and may exhibit a substantially spherical geometry or a truncated spherical geometry. The body may be substantially hollow. In one embodiment, portions of the textured surface may be metalized or have a coating placed thereon to enhance frictional engagement of the body with the atrial appendage wall. In another embodiment, a mesh bag is disposed within an LAA and one or more self-expanding bodies are disposed within the mesh bag. The mesh bag is then secured to retain the self-expanding bodies within the bag and the LAA.

A method and system are provided for percutaneously gaining access to oxygenated blood with one or more anastomosis devices and pumping such oxygenated blood directly to the aorta adjacent to the right atrium or left atrium via a VAD system. In one embodiment, a VAD system can be implanted with open surgery.

A method and system are provided for percutaneously gaining access to oxygenated bood with an anastomosis device and pumping such oxygenated blood to other arterial regions of the vascular system. In one embodiment, a system may include an anastomosis device extending through an opening of the atrial septum. A filament may be coupled to the anastomosis device. A snare may access the right atrium through the superior vena cava, grasp the filament, and withdraw the filament through the superior vena cava. The filament may then be used as a guide to direct a catheter, a conduit or some other structure into the right atrium of the heart via the superior vena cava. A flow path may be defined between the anastomosis device and an arterial location, such as in the aorta, such that at least some oxygenated blood may by-pass the left ventricle and be discharged into the aorta.

A medical device for use in delivering RF energy to a tissue opening is disclosed. In one embodiment, the medical device comprises a compliant electrode. The compliant electrode can include a shape memory material, such as NITINOL, to facilitate the electrode having at least one relaxed orientation. The electrode can be deployed from a delivery shaft inside the left atrium, for example, of a heart through the delivery shaft. The electrode can be configured to substantially conform to the tissue proximate the tissue opening. After energy is applied to the tissue between the left and right electrodes, the left electrode can be removed from the left atrium by being received back into the delivery shaft and the delivery shaft thereafter removed from the opening.
