  • Patent number: 10405858
    Abstract: Surgical instruments and their methods of use are described. In one embodiment, a surgical instrument includes a power transmission including a trigger and a fastener driver operatively coupled to the trigger. Actuation of the trigger from a first configuration to a second configuration moves the fastener driver between at least a first position and a second position. Additionally, an actuation lockout system operatively associated with the power transmission is moveable between a locked configuration and an unlocked configuration. The actuation lockout system prevents movement of the fastener driver from the first position to the second position when the actuation lockout system is in the locked configuration. Actuation of the trigger from the first configuration towards the second configuration moves the actuation lockout system from the locked configuration to the unlocked configuration.

  • Patent number: 10368972
    Abstract: A blood clot filter includes a number of locator members and anchor members, each of the members tipped with a retainer encompassed within bio-resorbable cover material. Upon delivery into a blood vessel, the locator and anchor members position the filter near the vessel centerline. After a period of time, the bio-resorbable cover material resorbs, allowing the retainer on the members to penetrate and attach to the vessel wall. A method of implanting the filter includes delivering the filter into a blood vessel and allowing the bio-resorbable cover material to resorb so retainers on the members can engage the vessel walls.
