Abstract: Medical devices, systems and methods for occluding a left atrial appendage of a heart with an implant are provided. In one embodiment, a medical device system includes a sheath for delivering the implant. The sheath includes, at a distal portion of the sheath, first and second deflectable portions that are each independently deflectable relative to first and second pivot locations, respectively. With this arrangement, at least one of the first and second pivot locations are adjustable along a longitudinal length of the distal portion of the sheath.

Abstract: A capture catheter is provided having a proximal end and a distal end. A tubular member extends between the distal end and the proximal end of the capture catheter. A capture sleeve is disposed at the distal end. An actuation assembly is disposed at the proximal end of the capture catheter. The actuation assembly includes a barrel having a plunger disposed therethrough, the plunger able to slide in the proximal and distal direction. The plunger is connected to a deploying member is disposed through a lumen extending through the tubular member. The deploying member is connected to the capture sleeve to translate movement in the distal and proximal directions. A flush port is provided aspirate the lumen having the deploying member. Stop mechanism are provided for preventing excessive movement in the distal and proximal directions.
