Abstract
An anchor device configured to connect a plurality of tissues to each other, includes a shaft having a longitudinal axis; and a first anchor part and a second anchor part which are separated from each other and which are each formed in the shaft. The first anchor part includes a plurality of elongated anchor arms that are allowed to be expanded in a direction of separating from the longitudinal axis of the shaft toward the second anchor part with a first position of the shaft being a base point. The second anchor part includes a plurality of elongated anchor arms that are allowed to be expanded in a direction of separating from the longitudinal axis of the shaft toward the first anchor part with a second position of the shaft being a base point.
Claims10
An anchor device configured to connect a plurality of tissues to each other, comprising:
- an inner shaft having a longitudinal axis;
- a first outer member and a second outer member which are separated from each other and which are each mounted on an outer peripheral surface of the inner shaft;
- and
- a first anchor part and a second anchor part which are formed in the first outer member and the second outer member, respectively,
- wherein the first anchor part includes a plurality of elongated anchor arms that are allowed to be expanded, from a contracted state, so as to separate in a direction away from the longitudinal axis of the first outer member and pivot in a direction away from the second anchor part so as to be in an expanded state, and wherein in the expanded state, distal ends of the plurality of the elongated anchor arms of the first anchor part are spaced apart from one another in a circumferential direction of the inner shaft,
- wherein the second anchor part includes a plurality of elongated anchor arms that are allowed to be expanded, from a contracted state, so as to separate in a direction away from the longitudinal axis of the second outer member and pivot in a direction away from the first anchor part so as to be in an expanded state, and wherein in the expanded state, distal ends of the plurality of the elongated anchor arms of the second anchor part are spaced apart from one another in the circumferential direction of the inner shaft,
- wherein the first outer member and the second outer member are longitudinally fixed at opposite ends of the inner shaft, respectively, in the contracted state and the expanded state of the plurality of elongated anchor arms of each of the first anchor part and the second anchor part, and
- wherein the plurality of the elongated anchor arms of the first anchor part move to a position at which an angle that each of the plurality of elongated anchor arms of the first anchor part forms with respect to the longitudinal axis of the inner shaft is more than 90° when external pressure is applied to the elongated anchor arms of the first anchor part in a direction extending along the longitudinal axis of the inner shaft from the second anchor part to the first anchor part, or wherein the plurality of the elongated anchor arms of the second anchor part move to a position at which an angle that each of the plurality of elongated anchor arms of the second anchor part forms with respect to the longitudinal axis of the inner shaft is more than 90° when external pressure is applied to the elongated anchor arms of the second anchor part in a direction extending along the longitudinal axis of the inner shaft from the first anchor part to the second anchor part.
