A surgical device for injecting a chemical agent within a subject for use in endoscopic injection therapies is disclosed. The device includes a support body, a motion transmitting unit, an agent delivery system and a guide housing. The motion transmitting unit is movable relative to the support body. The agent delivery system includes a needle for extending into a subject and structure defining a conduit between the support body and the needle. The guide housing has a flexible elongated body, an internal elongated passage and friction reducing material lining the passage. At least a portion of the motion transmitting unit adjacent the needle is slideably housed within the guide housing. The device offers a surgeon improved ease of needle extension and retraction when the distal end of the endoscope is bent at acute angles.

An endoscopic surgical device for retrieving severed tissue or foreign bodies from within a subject is disclosed. The device comprises a support unit and a tissue retrieving net system. The net system is carried by the support unit and may be inserted into the subject through an orifice or small incision and operated to retrieve tissue that has been severed by a conventional method. The net system comprises a net, a net actuator, a net deployment and retrieval assembly for transmitting motion between the net and its actuator. The net system further comprises at least one net connector disposed such that only one connector is within an articulation zone, defined by locations of severe bending of the device during operation.

A method and apparatus for obtaining esophageal cells for diagnostic purposes. A distal end of a support body is inserted in a patient's stomach via the esophagus and mouth. A balloon at the distal support body end is inflated. The support body is withdrawn until the balloon engages the sphincter. A support body location is marked that is a predetermined distance from the patient's dental arch. The balloon is deflated and the support body is withdrawn so that the marked location is adjacent the patient's dental arch. The support body is withdrawn a second predetermined distance and a second support body location is marked. A cell collecting element is deployed from within the distal end of the support body. The support body is reciprocated with the cell collecting element deployed so that cells from the esophagus are deposited on the cell collecting element.

A snare injection device for performing endoscopic transection procedures is disclosed. The device includes a snare system and a needle system, each containing actuator components separately routed in one of two channels of an elongated dual lumen. Deployment of the snare and needle are independently operated by two separate handle controls. The device includes needle travel stop and anti-puncture features for safety and ease of use.

A valve for use in irrigating, accessing and sealing the instrument channel of an endoscope is disclosed. The valve is adapted for installation onto an endoscope instrument inlet port. The valve includes a body, a flip cap, and a seal curtain. The body has an open end adapted for connection to the inlet port, interior walls defining an cavity, and an outer surface defining a valve entry port. The entry port is connected to a channel open to the cavity. The flip cap is removably connectable to the valve entry port and has a slit therethrough. The seal curtain contains a flexible cylindrical portion, and a lid at one end, and is removably insertable into the cavity. A longitudinal axis of the seal curtain in an installed position within the cavity is at an angle with respect to a longitudinal axis of the body.

An endoscopic surgical device for retrieving objects, such as for example, severed human tissue, foreign objects or impacted food bolus, from within a subject is disclosed. The device includes a body and handle movable relative to the body, a tubular member fixed to the body, a link having a first end fixed to the handle and a second end remote from the body, and a net including a loop and a net element. The loop is expandable and collapsible by action of the handle relative to the body. The loop retains an expanded configuration when deployed to allow for the capture certain objects that were otherwise difficult to capture because of positioning, location, or object characteristics. The loop may be constructed of flat wire and form a polygon shape when deployed. Structure at the distal end of the loop may propel and retain the loop into an open position when in use in narrow organs such as the esophagus.

A polyp removal tool and method of use is disclosed. The tool includes a main body, an elongated hollow conduit fixed to the body, a handle, a cable assembly, a suction assembly and an irrigation system. The handle is used to actuate a snare at the end of a cable for transecting of polypoid tissue. The suction assembly is used in pre-conditioning the tissue for cutting and in polyp retention after cutting. The irrigation system is included for tissue recovery after transection. The tool may include a screen for capture of tissue within the device.
