Abstract: A protective mask includes a transparent impermeable membrane; a frame that substantially surrounds and is coupled to a perimeter of the impermeable membrane and is configured to be positioned about a face of a user; a seal operatively coupled to the frame that seals against a face of the user and extends around a perimeter of the frame, wherein the frame and the seal are substantially impermeable to the passage of air therethrough; an air passageway formed in the frame; and a filter element disposed to filter air passing through the air passageway. The air passageway and the filter element are disposed on a bottom portion of the frame.

Abstract: The present disclosure relates to a protective mask to deactivate damaging agents. In some examples, the mask includes a filter element that traps particles of the damaging agent. A sanitizing emitter permeates the filter element with a sanitizing agent to deactivate the damaging agent. In some examples, the sanitizing agent is ultraviolet light configured to deactivate a virus such as SARS-CoV-2.

Abstract: A device for dividing a fibrous structure comprising an expandable member positioned near the distal end of a catheter and in fluid communication with the lumen of the catheter so that the expandable member can be biased between an inflated state and a deflated state to tension the fibrous structure, and electrosurgical elements situated on or proximate to an outer surface of the expandable member and configured to deliver electrical and thermal energy to the tensioned fibrous structure in a manner that results in division of the tensioned fibrous structure. A method for dividing a fibrous structure comprising positioning proximate the fibrous structure an expandable member having electrosurgical elements, expanding the expandable member outwards to tension the fibrous structure across the electrosurgical elements, and activating the electrosurgical elements to deliver energy to the tensioned fibrous structure to divide the tensioned fibrous structure.

Abstract: An endoscopic surgical instrument is provided. The instrument includes a housing, a handle, an elongated shaft extending distally from the housing and defining a longitudinal axis, an end effector assembly, a drive assembly, a clevis, a first link, and a second link. The end effector assembly is disposed adjacent a distal end of the elongated shaft and includes a first jaw member and a second jaw member. The first link is pivotably connected to the clevis about a first pivot axis, and is pivotably connected to the first jaw member about a first jaw member pivot. The second link is pivotably connected to the clevis about a second pivot axis, and is pivotably connected to the second jaw member about a second jaw member pivot. The first pivot axis and the second pivot axis are offset from the longitudinal axis.

Abstract: A tissue ablation device is provided for use in soft tissue and/or in bone. It is configured to include an inner probe with a first electrode and a second electrode and an outer needle through which the inner probe extends. After the inner probe is directed therewithin to a target, the outer needle can be withdrawn to expose space between the first and second electrodes to form an RF or other energy field for tissue ablation therebetween upon actuation of an energy source. Such embodiments may include methods for tissue ablation and placement of stabilizing materials.
