Abstract:
A reinforcing element (908) used to structurally reinforce a portion of an endocardial surface of a heart (900). The reinforcing element (908) may include a preshaped patch and/or a plurality of preshaped flexible conduits (910). The reinforcing element (908) once inside the left ventricle may be expanded state to structurally reinforce a portion of a heart (900).
Abstract:
The present invention provides devices, systems, methods and kits for endoscopically accessing a body cavity and providing a directed pathway toward a target tissue within the cavity. The directed pathway is provided by an access sheath which is positioned in a desired configuration, generally directed toward the target tissue. Depending on the location of the target tissue and the desired angle of approach, the access sheath may be required to maintain one or more curves in one or more planes to properly direct the interventional devices. In addition, the access sheath has a locking feature to hold the sheath in place and maintain the desired configuration. Interventional devices may then be passed through the sheath to the target tissue.
Abstract:
The invention relates to devices, systems, and methods for percutaneously suturing biological material, such as a patient's tissues. In one embodiment, a suturing device includes first (140) and second (142) tissue engaging members connected to one another by a first interconnecting member (144). In another embodiment, systems and methods are provided for forming holes through two overlapping layers (60, 62) of tissue. Subsequent to forming holes through the two layers of tissue, the suturing device is positioned through the holes to join or bring into contact the two layers of overlapping tissue.
Abstract:
An element is expanded in the left ventricle to isolate part of the left ventricle. The element has a generally convex outer surface and an apex which together define a desired geometry of the left ventricle. The isolated part of the wall of the left ventricle may be left so that the wall naturally forms around the element or the isolated portion of the ventricle may be evacuated and/or filled. The element may also be used to isolate part of the left ventricle containing a ventricular septal defect or other perforation or opening in the ventricular wall.
Abstract:
The present invention provides methods and devices for closing two overlapping layers of tissue in a mammalian heart, for example a patent foramen ovale PFO. The closure devices may take a number of different forms and may be retrievable. In some embodiments, the closure devices may be delivered with a catheter capable of puncturing mammalian tissue.
Abstract:
The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.
Abstract:
Various aspects of the present disclosure are directed toward apparatuses, methods, and systems as relating to occlusion. In certain instances, the apparatuses, methods, and systems may include a device for placement in vessels, appendages, and openings in a body. The device may include a unitary frame having a face portion that includes a center frame portion a plurality of elongate members.
Abstract:
The invention is directed to a port closure device including a mesh implant, supports for the mesh implant, and a suture to close the incision point above the mesh implant.
Abstract:
Disclosed herein are implantable fistula treatment devices and methods. In some embodiments, a distal anchor for an implantable fistula treatment device may comprise a suture and multiple foldable members including at least a distal-most foldable member and a proximal-most foldable member. The distal-most foldable member may comprise a suture attachment structure. The proximal-most foldable member may be configured to couple to a surface of a body lumen at a distal opening of a fistula.
