  • Patent number: 10881402
    Abstract: Various embodiments of a frame for attaching an adjunct to an end effector of a surgical device are provided. In one embodiment, the end effector can include upper and lower jaws, and the frame can include features for releasably engaging one or the jaws. The frame can also include retaining features for coupling an adjunct to a tissue-facing surface of the frame, thereby releasably coupling the adjunct material to the jaw of the end effector. In some implementations, the frame can include a plurality of retaining features that are configured to engage the adjunct material to create a tension in the adjunct material, which can further assist with securing the frame to the jaw. In other embodiments, a removable applicator member is provided for retaining at least one adjunct material and for aligning and coupling the adjunct material to a frame.

  • Patent number: 10881497
    Abstract: A vascular flow diverter includes a tubular mesh framework which includes a mesh cover and an opening. The tubular mesh framework is collapsible and configured to expand from a collapsed shape to a tubular shape when the vascular flow diverter is deployed. The mesh cover conforms to the shape of the tubular mesh, is surrounded by the tubular mesh framework, and is less porous than the tubular mesh framework. The opening is located within the mesh cover. A delivery wire passes through the opening in order to guide the flow diverter into place over an aneurysm.

  • Patent number: 10835341
    Abstract: A handle assembly for use with a surgical instrument includes a housing defining a contact wall, a movable handle, a plunger, a linkage, and a feedback mechanism. The plunger is disposed at least partially within the housing and defines a longitudinal axis. The linkage interconnects the movable handle with the plunger such that actuation of the movable handle results in longitudinal translation of the plunger relative to the housing. The feedback mechanism is configured to provide audible feedback to a user, and includes an indicator snap wire and a track defined by a wall of the housing. The snap wire is configured to move along the track in response to longitudinal translation of the plunger. The snap wire is configured to engage the contact wall of the housing to create a sound that is audible to a user when the movable handle has been actuated a predetermined amount.

  • Patent number: 10828037
    Abstract: Detachment of an implant from a delivery assembly can be electrolytic and provide an electrical current pathway through a fluid within a portion of a delivery system containing the delivery assembly. After the implant is located at a target location within a patient, a voltage potential is applied between (i) a delivery electrode electrically connected to an electrolytic detachment zone and (ii) an infusion electrode disposed outside of the patient and electrically connected to the electrolytic detachment zone via a fluid from a fluid source disposed outside of the patient. While applying the voltage potential, the fluid can be flushed from the fluid source past the detachment zone.
