A medical device and tension member for use in a subject enables fixation of tension members and transmission of force from tissues to energy converters or to natural or prosthetic bones or other prostheses. The medical device includes an anchor block having a knob extending from its surface, such knob configured to engage a looped tension member. The tension member includes a looped portion configured to engage the knob, an intermediate portion, and a tissue engaging portion configured to engage tissue in a subject. The looped portion is connected to the tissue engaging portion via the intermediate portion. A system is provided for use in a subject and includes at least one looped tension member, an operational device, and at least one medical device configured to couple the looped tension member and the operational device.

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.

Elements for versatility of a prosthetic anchor

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.

A system for studying a beating explanted heart comprises a fluid inflow circuit configured for coupling to an explanted heart to direct fluid for flowing into a ventricle of the heart, and a fluid outflow circuit configured for coupling to an explanted heart to direct fluid flowing out of the ventricle of the beating heart. A flow meter coupled with the inflow circuit measures the inflow rate of fluid into the heart ventricle and a flow meter coupled with the outflow circuit measures the outflow rate of fluid out of the heart ventricle. A processing system converts the inflow and outflow rates into incremental volume changes in the volume of the heart ventricle and adds and subtracts the incremental volume changes from a relative volume of the heart ventricle to study volume changes in the explanted heart while it is beating.
