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. |

1. A surgical implant for affixing a prosthetic tension member within a patient, comprising:
an anchor block having a first surface, the anchor block configured to be secured within the patient; at least one knob including a channel and a rim, the knob rigidly extending from the first surface of the anchor block to the rim and through the channel, a first plane, and a second plane, the first plane being offset from the first surface between the first surface and the rim, and the second plane being transverse to the first plane; and the channel circumscribing at least a portion of the knob in the first plane between the first surface and the rim, the channel having a curved surface in the first plane and an arcuate profile in the second plane for receiving a looped tension member therein, wherein the anchor block and the knob are each formed from a biocompatible material and further wherein the anchor block defines an actuator arm, the actuator arm being coupled to an energy converter configured to convert linear mechanical energy to at least one of an electric energy, a rotational mechanical energy, a pneumatic energy, and a hydraulic energy. |
