Abstract: Retrieval assemblies configured to capture an obstruction located in a bodily duct of a patient and associated methods are provided. According to one implementation a retrieval assembly is provided that includes a proximal collar, a distal collar and a plurality of elongate clot capturing elements that each has proximal and distal ends that are respectively coupled to the proximal and distal collars. The retrieval device is mounted on an elongate wire with at least one of the proximal collar and distal collar being slideable along a portion of the length of the elongate wire to enable the retrieval device to transition from an unexpanded state to an expanded state. At least a portion of one or both of proximal and distal end sections of the elongate clot capturing elements being arranged curved about a longitudinal axis of the retrieval device when the retrieval device is in the unexpanded state.

Abstract: Suture retention devices are disclosed that are configured to grip one or more end portions of a suture at multiple locations. According to one aspect, at least first and second gripping locations are provided between a depressible first actuator and a wall of housing in which the first actuator resides. In addition, at least third and fourth gripping locations are provided between the depressible first actuator and a depressible second actuator located inside a cavity of the first actuator. According to another aspect, at least first and second gripping locations are provided as a result of an actuator rotating between first and second angular positions inside a housing of the suture retention device. According to another aspect, suture retention devices that include indica of the size of a puncture wound site are provided.

Abstract: Retrieval assemblies configured to capture an obstruction located in a bodily duct of a patient and associated methods of manufacture are provided. According to one implementation a retrieval assembly is provided that includes a distal collar fixed stationary on an elongate wire, a proximal collar slideable along a portion of the length of the elongate wire, and a plurality of shape memory elongate capturing elements that each has a proximal end coupled to the proximal collar and a distal end coupled to the distal collar. The retrieval device is configured to automatically transition from a radially constrained state to an expanded rest state with the proximal collar located nearer the distal collar when in the expanded rest state. As the retrieval device transitions from the radially constrained state to the expanded rest state, proximal portions of the capturing elements invert around the proximal collar.
