A handle assembly includes a drive wire coupled to an expandable end effector, the wire having a diameter of no more than 3 French and a handle cannula receiving the wire therethrough, rotation of the handle cannula transferring torque to rotate the wire. The assembly also includes a shaft receiving the handle cannula, rotation of the shaft transferring torque to rotate the handle cannula. The assembly further includes an actuation assembly receiving the shaft, the actuation assembly coupled to a sheath sized to receive the wire and end effector therethrough, the actuation assembly moveable between a proximal configuration in which the sheath is moved proximally to expand the end effector and a distal configuration in which the sheath is moved distally to retract the end effector, the actuation assembly including a rotation mechanism transferring torque to the shaft to rotate the shaft.

Single filter and multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a blood filtering system captures and removes particulates dislodged or generated during a surgical procedure and circulating in a patient's vasculature. In some embodiments a filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

A hand-held gripping device that allows a surgeon to reach interior portions of a person's anatomy, includes a gripping portion having a pair of jaws and/or nets movable relative to each other between fully clamped and fully opened positions thereof, a handle portion spaced apart from the jaw portion by a bendable central portion that is hollow and corrugated, with a cord extending therethrough.

Inverting tube thrombectomy apparatus for removing clot that are configured to prevent compression of the apparatus that may separate the distal end of the apparatus from the clot and may make it difficult to advance the apparatus to engage with the clot, particularly in a tortious vessel. The apparatuses and methods of using them described herein may be adapted to prevent tension in the flexible tube that is rolling and inverting over the distal end of the inversion support catheter when capturing a clot. Also described herein are inverting tube thrombectomy apparatus that are configured to reload either automatically or manually within the vessel to capture additional clot material.

In accordance with an aspect of the present disclosure, a tissue extraction device may include a bag having an interior and a plurality of cutting elements extending through the interior of the bag.

An self-actuating grasping device and corresponding method of using the grasping device for retrieving a foreign object from a location in a patient's body. The grasping device has a handle with a self-actuating mechanism, an actuator on the handle coupled to an actuator wire, an elongated shaft member extending distally from the handle with the actuation wire coaxially disposed therein and opposing jaws at a distal end of the elongated shaft member that are coupled to the actuation wire and pivot between open and closed configurations. The self-actuating mechanism has a bias that imparts a closing force to the opposing jaws through the actuation wire. Actuation of the actuator is configured to impart an opening force to the opposing jaws through the actuation wire.

In embodiments of an obstruction removal device, system, and/or method, a removal tool and an expandable member are configured to be disposed at a distal end of a delivery tool. The removal tool may include peeler wires and hook wires that are configured to at least partially separate an obstruction from an inner surface of a vasculature. The expandable member is configured to at least partially surround the removal tool and is further configured to grasp at least one portion of the removal tool and the obstruction as the expandable member transitions from an expanded state to a contracted state when the delivery tool is removed from the vasculature to remove the removal tool and the obstruction from the vasculature.

Disclosed herein is a fecalith treatment system for the removal of an impacted fecalith from a formed diverticula. The fecalith treatment system having an endoscopic device having a steerable line configured to be introduced into a patient via the endoscopic device; and an articulable fecalith treatment device coupled to a distal end of a treatment conduit that is configured to be received therein the steerable line to be delivered to an operative position within the patient. Subsequently, the fecalith treatment device is configured to allow for the removal of the impacted fecalith without damaging the underlying diverticula tissue.

A catheter system for explanting an intracardiac medical device, comprising: a catheter having a distal catheter tip configured to surround the intracardiac medical device and an encapsulation tissue that has grown around the intracardiac medical device, and a deployable cutting element at the distal catheter tip.

The disclosure includes a balloon guiding sheath that includes an elongated sheath having a proximal end, a distal end opposite the proximal end, an inner tube extending between the proximal end and the distal end, an outer tube surrounding the inner tube and extending between the proximal end and the distal end, an access port located adjacent in the proximal end, a distal port located adjacent the distal end, and a working lumen extending through the elongated sheath between the access port and the distal port. The balloon guiding sheath also includes an inflatable balloon located on an outer surface of the elongated sheath adjacent the distal end, the inflatable balloon being fluidly coupled to an inflation lumen extending between the inflatable balloon and an inflation port located adjacent the proximal end.
