Abstract: A tissue removal tool for use with an endoscope. The tool includes a loop formed by a piece of wire. The loop is movable between an open position and a closed position. The shape of the loop is defined in the open position by a proximal portion and a distal portion. The piece of wire may have a cross-sectional height in the proximal portion unequal to a cross-sectional height in the distal portion.

Abstract: A disposable air and water (AW) valve assembly and suction valve assembly for an EUS instrument. The AW assembly includes an AW valve and an endcap for receiving the AW valve therebetween. The AW valve includes an AW stem connected to a valve stem. The suction valve assembly includes a suction valve disposed in a suction endcap. The suction valve also includes a valve stem. The valve stem is disposed between a suction valve opening such that portions of the valve stem extend beyond opposed ends of the suction endcap. The suction valve is formed from a suction stem and a piston connected to the suction stem.

Abstract: A medical device for performing an endoscopic procedure through an endoscope is provided. The device includes an elongated catheter having a first lumen and a second lumen; a needle system for injecting a target tissue within a body; and a base disposed at a proximal end of the catheter. The actuator tube is inserted through the base and the first lumen. A needle housing member is positioned between the needle and the first lumen when the needle is in a stored position. The needle housing member has a predetermined length so that the needle is disposed within the needle housing member when the needle is at the stored position. The needle housing member has a continuous inner surface and prevents the needle from penetrating the first lumen. The needle includes a tip, deflected towards a center axis of the needle. The first and second lumens have different deflected forces.

Abstract: A suction valve stem, a suction valve, an endoscopic valve kit, and a method for molding a stem are provided. The suction valve stem includes: a button head, and a stem body connecting to the button head. The stem body includes: an air passage through the center bore, a recessed slot, disposed on the stem body below the button head and above the side opening, a sealing area, disposed on the stem body below the side opening, and a flat, disposed on the stem body. The air passage includes a side opening disposed on side surface of the stem body and a bottom opening disposed at a bottom end of the stem body. The recessed slot is disposed 90 degrees from the side opening. The flat is disposed 90 degrees from the side opening and has a fluid communication to the bottom end of the stem body.

Abstract: A carpet cleaning apparatus comprises a housing and wheels rotatably connected to the housing for moving the housing over a carpet. A brushroll, supported by the housing, is rotatable about a first axis. A pulley, supported by the housing, is rotatable about a second axis parallel to the first axis. A drive wheel, supported by the housing, is rotatable about a third axis parallel to the first axis. A belt has inner and outer surfaces. The inner surface extends about and engages the brushroll and the pulley. The outer surface engages the drive wheel. The belt is pulled by the pulley downward against the drive wheel for the drive wheel to drive the brushroll through the belt.
