Abstract: A closure device (320) is provided for suturing a puncture. The closure device (320) includes a suture (322, 822), an elongate support (328), a suture-positioning support (330), and an elongate dilator (344). The suture-positioning support (330) is coupled to a distal end portion (332) of the elongate support (328), laterally extendable with respect to the distal end portion (332) of the elongate support (328), and configured to removably receive the suture (322, 822). The dilator (344) is configured to be inserted through the puncture, and has a proximal end (348) that is coupled to the distal end portion (332) of the elongate support (328). The closure device (320) is configured to allow movement of the distal end portion (332) of the elongate support (328) with respect to the proximal end (348) of the dilator (344) with at least two degrees of freedom. Other embodiments are also described.

Abstract: A weight-distributing exoskeleton capable of supporting and/or control the distribution of at least part of the weight of a protective garment and/or face shield proximate the knee of the user. The exoskeleton may include a plurality of leg structures, each leg structure including a knee joint or knee hinge configured to bear the load of the protective garment, and a foot member including a magnetic quick release mechanism configured to control quickly engage with and release from the leg structures. The weight of the protective garment and/or face shield is transferred to the floor such that the user bears little to no burden of carrying it.
