A tissue clipping device for clipping tissue and methods of using the same. The device includes a tissue clipping assembly for clipping tissue and a drive assembly operable to control the operation of the tissue clipping assembly. The tissue clipping assembly includes a distal arm that is linearly extendable and retractable to clip tissue. The tissue clipping assembly may be decoupled from the drive assembly after tissue is clipped. Additional clipping assemblies may be deployed with the drive assembly to close larger defects.

Linear tissue clipping device

An endoscopic resection assembly includes an adaptor configured to adapt to an endoscopic device. A pusher is disposed on the adaptor by inserting the adaptor into the central opening defined by the pusher. A cutting device includes a snare loop and a snare drive cable, and is removably coupled to the pusher. The cutting device is configured to resect a tissue when the snare loop is contracted by activation of the snare driver. A clip for engaging onto the tissue can be loaded onto the adaptor at a position distal to the pusher.

Endoscopic resection assembly

An endoscopic device, includes a clip assembly and a driving assembly. The clip assembly includes a first jaw, a second jaw, a pivot, a housing having an internal channel, and a release portion connecting to the first and second jaws. At least a portion of the first and second jaws is disposed within the internal channel, the first and second jaws selectively move along with the internal channel. The driving assembly includes an outer sheath, an inner tube, movably disposed within the outer sheath, and a driver, movably disposed within the inner tube, and removably received within the release portion. The driver is unbrokenly released from the release portion by a predetermined pull force. The housing and the outer sheath form a releasable handshake engagement. The inner tube extending into the housing prevents the handshake engagement from disengaging.

Clip and clip assembly

A device and assembly for ligating a target tissue to restrict blood flow to the tissue, where the device is a ligating device that is irreversibly tightened by a cinch component. The device further has a hook to hold the ligating element on a delivery tool. The ligating element can be a continuous loop or can be a clip and can be repositionable until the cinch is used to tighten it. The cinch holds the ligating device on the loop while being positioned, and then secures the ligating device once it is positioned around target tissue to which a user desires to restrict blood flow. A method of using the assembly includes an actuator assembly, drive wire, and pusher element to manipulate the ligating device and cinch component.

Cinch ligating assembly

The present subject matter discloses a tissue removal tool for use with an endoscope. The tool comprises a loop formed by a piece of wire and movable between an open position and a closed position, and a transmitting assembly comprising: a handle; and a link having a first end attached to the handle and a second end attached to the loop, the loop portion being movable between the open and closed position by action of the handle. The loop is defined in the open position by a proximal portion and a distal portion. The widest portion of the loop is more proximal to a proximal end of the loop than the mid-point of the length of the loop is.
