A gold marker recovery device for radiotherapy positioning and its using method comprises a positioning gold marker and a recovery clamp, the positioning gold marker comprises a gold marker body and an elastic fixed structure, the elastic fixed structure comprises a fixed segment, an extending segment and a spiral segment connected in sequence; the fixed segment is embedded in the gold marker body so that the fixed segment is closely connected with the gold marker body, A magnetic ball is arranged at one end of the gold marker body away from the extending segment; the recovery clamp comprises an operating handle, the rear end of the operating handle is connected with an outer sheath tube in a hollow structure, and the outer sheath tube is connected with a zipper for driving the clamp to open and close.

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.

Provided are medical devices, systems and methods for retrieval and/or extraction of a corpus located in a tubular organ. Systems of this disclosure are configured for carrying out various procedures for removal of occlusive corpus from tubular organs, for example thrombectomy.

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.

A device for providing access to a nodule, lesion, or pathological area in a lung or other body organ or lumen. The device includes a sheath portion having a proximal end and a distal end and a plurality of stabilization wires. The sheath portion includes a primary lumen that extends from the proximal end to the distal end and a plurality of secondary lumens that extend from the proximal end to the distal end. The stabilization wires are configured to be slidably received within the secondary lumens. The length of the stabilization wires is greater than the length of the secondary lumens.

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.

Funnel-trap type devices made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices are described. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.

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.

An endoscopic device for retrieving an object from within a human body is disclosed. The device includes a support assembly, a transmitting assembly, a wire, and a net element. The support assembly has a base and a tubular member. The transmitting assembly includes a handle and a motion transmitting link fixed to the handle and extending through at least a portion of the tubular member. The wire defines a loop portion and two leg portions. A proximal end of each leg portion is secured to the link by a first connection and the two leg portions are secured to each other by at least a second connection distal from the first connection. The net element has a distally protruding portion secured to the loop portion and a proximally protruding portion secured relative to the leg portions.
