Abstract: A prosthetic anchor to be attached to a natural or prosthetic structure of a human or animal. The anchor includes a central layer with first and second surface. A plurality of fiber bundles, each with a medial portion, are concentrically embedded within the central layer to substantially define a horseshoe-shaped pattern. A substrate element is configured to be secured to the natural or prosthetic structure and to receive the second surface of the central layer. A securing element operably coupled to the second surface of the central layer is configured to secure the central layer to the substrate element in at least two positions.

Abstract: The invention is generally concerned with supporting the ventricular septum (9) of the heart during mechanical compression of at least one ventricle. The ventricular septum (9) is supported by a septal splint (1) coupled by at least one bolster (48) to a free-wall actuating mechanism (6). The septal splint (1) has a central patch (2) with radial strands (3) extending to the junction of the free wall (7) and septum (9). The radial strands (3) traverse the ventricular free wall (7) at the junction. Affixation of each strand (3) to the heart wall is controlled by an internal element (18, 21) and external element (19, 38) of the bolster (48) and a placement tool (46) to avoid risks of injuring major coronary blood vessels. The placement tool (46) is configured to hold, deliver, stabilize for passage, and release the internal and external elements (18, 21, 19, 38) of the bolster (48), along with accompanying radial strands (3) from the septal splint (1).

Abstract: An actuation system for assisting the operation of the natural heart includes an actuator element adapted to be positioned proximate a portion of a heart wall. The actuator element is operable for acting on the heart wall portion to effect a change in the shape of the heart. A shape-limiting element is configured for being positioned proximate a heart wall. The shape-limiting element is operable for flexing to assume a curvature no greater than a predetermined curvature when the heart wall is acted upon and maintaining that predetermined curvature to control the shape of the actuated heart.

Abstract: An insertion kit for positioning a plurality of filaments into muscle includes at least one holder that is configured for being attached to an end portion of the muscle. The holder is coupled with a guide, such as on a frame. The guide conforms the muscle to a desired shape. An inserter, used in conjunction with a plurality of needles, inserts a plurality of filaments into the muscle.

Abstract: Devices and methods for treating a diseased heart including devices and methods for remodeling or reconfiguring a shape of a diseased heart, assisting in function of a diseased heart, and stabilizing such devices on a diseased heart. In some embodiments, the devices and methods include one or more segments for changing a shape of the heart or a portion thereof, and methods for using such devices and methods.

Abstract: A geometric reconfiguration assembly for the natural heart having a collar configured for surrounding the natural heart. The collar can include a plurality of supports configured for positioning on the epicardial surface of the heart. Supports can be joined with connectors that can permit or provide slight deformation of the assembly. An external shell or skin portion can be provided around the supports an/or connectors.

Abstract: A cyclical clasp for use with the natural heart. The cyclical clasp has a plurality of members configured to be positioned adjacent the epicardial surface of the heart. The members are joined by at least one connector wherein the members are fixed in a spatial or spaced relationship relative to each other such that a portion of the heart wall is displaced inwardly during at least a portion of a cardiac cycle to reconfigure a chamber of the heart as contiguous portions of truncated ellipsoids. A cyclical force is applied to the wall of the heart chamber to reduce adverse effects of reconfiguration during diastolic filling.

Abstract: A static device for use with the heart that has a plurality of members configured to be positioned adjacent the epicardial surface of the heart. The members are joined by at least one connector wherein the members are fixed in a spatial or spaced relationship relative to each other such that a portion of the heart wall is displaced inwardly. The member(s) can be configured in a rectangular shape, and preferably includes an inner surface having a curved configuration. In one embodiment, the device can have first and second member that are positioned in a spaced relationship relative to each other about 180 degrees apart. The first member is configured to be positioned adjacent the anterolateral surface of the chamber, and the second member configured to be positioned adjacent the posteromedial surface of the chamber.

Abstract: A geometric reconfiguration assembly for the natural heart having a collar configured for surrounding the natural heart. The collar can include a plurality of bands, such as thin bands of about 0.2 mm in thickness, in a spaced relationship to each other, and a connector bar intersecting the plurality of bands and configured for maintaining the spaced relationship of the bands to each other. The collar may include a plurality of bands, such as from about 2 to about 10 bands, that are positioned parallel to each other. The bands can each be made of a biomedical material, such as polyacetal or a metal, such as titanium or steel.

Abstract: A method of providing extracorporeal to intracorporeal power transfer in a patient employs a cylindrical primary coil inserted into a segment of small intestine which has been separated and closed at one end. The open end is attached to the abdominal wall providing an opening to the exterior of the body. A secondary coil is formed by wrapping a wire around the serosa of the segmented small intestine. This is in effect a transformer which will transfer energy from the primary coil to the secondary coil. The vascularization of the segment provides for rapid and efficient heat dissipation. This device can be used to power heart assist devices and artificial hearts. Since it is located in an internal pouch, proper location of the primary coil is ensured.
