    摘要: An improved catheter having a closed distal end and a valve adjacent the distal end which communicates the lumen of the catheter with the exterior of the catheter to permit the infusion or aspiration of fluids between the catheter and the vessel in which the catheter is positioned. The valve is preferably in a plane which is oriented at an angle to the longitudinal axis of the catheter, and is preferably in an area of reduced wall thickness to facilitate opening and closing.

    摘要: A surgical device is described herein that can be used to fire different types and sizes of disposable loading units. In a preferred embodiment, the device applies parallel rows of surgical fasteners to body tissue and concomitantly forms an incision between the rows of staples during an endoscopic or laparoscopic surgical procedure. The device can be utilized with disposable loading units configured to apply linear rows of staples measuring from about 15 mm in length to about 60 mm in length and can be used to fire disposable loading units containing surgical clips and individual staples.
