    摘要： A joint distraction device that is wearable by a patient and user-friendly and associated methods of joint distraction. Such devices can include first and second anchors that secure portions of the patient's body proximal and distal of the joint, the anchors each being attached to a beam and a distance between first and second anchors being adjustable so as to hold the joint being investigated in distraction. For distraction of a wrist joint, the first anchor can be a finger clamp and the second anchor can be an arm sleeve. The finger clamp can include multiple finger traps. The distance between anchors can be adjusted by an adjuster, by extending the beam or by moving an anchor incrementally along the beam. Advantageously, the device is fully wearable by the patient without being attached to external components, thereby improving patient comfort, portability and ease of use.

    摘要： An intervention guidance device (10) includes a main body portion (100) and a guidance portion (200). The guidance portion (200) has a contracted configuration and an expanded configuration. In the expanded configuration, the guidance portion (200) has a central area (201) and a closed outer edge (202). In the contracted configuration, the outer edge (202) is farther away from the main body portion (100) than the central area (201), and the guidance portion (200) is restorable from the contracted configuration to the expanded configuration. In the intervention guidance device (10), the radial dimension of the guidance portion (200) is larger than the distance between the chordae tendineae, so that an effective access path that does not cross the chordae tendineae can be established, the subsequent implantation of a heart valve prosthesis does not pass through the chordae tendineae, and the success rate of a heart valve prosthesis implantation surgery can be improved.

    摘要： A device for attaching, relocating or reinforcing tissue includes a first tissue anchoring portion having a support plate and a plurality of barbs extending from the support plate for engaging tissue at a first location, a second tissue anchoring portion having a support plate and a plurality of barbs extending from the support plate for engaging tissue at a second location which is different from the first location, and a connection element, such as a suture or a mesh structure, interposed between and interconnecting the first tissue anchoring portion and the second tissue anchoring portion. The support plate of at least one of the first tissue anchoring portion and the second tissue anchoring portion may have longitudinally axially formed therethrough a bore for receiving the connecting element so that the surgeon may pull on the end of the connecting element to adjust the distance between the first tissue anchoring portion and the second tissue anchoring portion.
