Abstract: A coupler device for interfacing between a biopsy driver and an intraosseous device includes a drive body having a distal drive receptacle. The drive body is rotatable around a longitudinal axis. The distal drive receptacle is configured to drivably couple to a drive portion of the intraosseous device. A distal coupler portion is coupled to the drive body and is configured to operate a distal latch member. The distal latch member latches the drive body to the intraosseous device when the distal coupler portion is in a distal coupler latch position. The distal coupler portion has a distal housing portion that is movable in either of a distal direction or a proximal direction. The distal coupler portion has a distal release position and a proximal release position. The distal housing portion is configured to move the distal coupler portion to a release position to operate the distal latch member.

Abstract: A bipolar electrosurgical pleura sealing device includes an electrosurgical probe assembly having a coaxial arrangement that includes an inner stylet, a first intermediate cannula, a second intermediate cannula, and an outer cannula, having appropriate insulation. A first mesh electrode connects to and extends between a distal end portion of the inner stylet and a distal end of the first intermediate cannula, and is movable between a first extended position and a first retracted position by an axial movement of the inner stylet and/or the first intermediate cannula. A second mesh electrode connects to and extends between a distal end of the second intermediate cannula and a distal end of the outer cannula, and is movable between a second extended position and a second retracted position by an axial movement of the second intermediate cannula and/or the outer cannula.
