A surgical instrument with articulated jaw structure includes a frame and two jaws. The jaws have proximal portions that are mounted to each other for movement in a substantially parallel relation between a fully open position wherein the jaws are separated for receiving tissue therebetween and an approximated position wherein the jaws are closer together. Preferably, the jaws are in the fully open position when the distal portion of at least of the jaws is located in an extended position and are in the approximated position when the distal portion of the extended jaw or jaws is located in a retracted position. The surgical instrument may further include a detachable knife assembly and knife actuating mechanism.

The present invention is directed to an improved anesthesia manifold and an improved induction valve mechanism. A plurality of induction valve elements may be joined or 'ganged' together in order to define a manifold. In the preferred embodiment of the induction manifold, at least two individual valve elements are combined to form the manifold. Each of the plurality of valve elements includes the following components: (1) a valve body; (2) a first inlet port carried by the valve body and defining at least in part a central fluid communication flow path for supplying intravenous fluid to patient; and (3) a second inlet port carried said valve body and at least in part defining an anesthesia drug inlet. Each of the plurality of valve components: (1) an induction valve mechanism which maintains said second inlet port in a closed condition until a predetermined amount of pressure is applied thereto; (2) a back flow valve mechanism which maintains said induction valve components in open condition to permit at least one of the following operations: (a) aspiration; (b) back flow; (c) purging; and (d) sampling. Additionally, a control mechanism is provided for each of the plurality of individual valve components to actuate said induction valve mechanism and said backflow valve mechanism.

A laparoscopic stapler with a blocking body is disclosed. The blocking body allows the stapler to be inserted into the abdominal cavity through a cannula and removed therefrom until the staples are fired. When the staples are fired, the blocking body allows the stapler to be removed from the abdominal cavity of the patient through the cannula. After the staples have been fired and the stapler is removed from the abdominal cavity, the blocking body is in a blocking position where it then prevents the stapler from being reinserted through the cannula.

A trocar for placement in the lumen of a cannula to facilitate inserting the cannula through a wall defining a body cavity is disclosed. The trocar has a replaceable tip portion which affords continuous sharp cutting surfaces even in a completely reusable trocar.

An external ventricular drainage assembly includes a ventricular drainage catheter which can be placed in the ventricles of a patient's brain and which is connected to a suture tab for securing the catheter to the patient and for preventing relative movement between the catheter and patient. A valve is connected to the catheter for selectively opening and closing the external ventricular drainage assembly to fluid flow. An adapter is connected to the valve for providing access to the fluid flow path within the assembly. A one-way valve is connected to the adapter. A first length of flexible tubing is connected to the one-way valve and is joined through a connector to a second length of flexible tubing. A collection reservoir is connected to the second length of flexible tubing and includes an entry and outlet port. A drip chamber is positioned between the second length of flexible tubing and the collection reservoir.

A shunt system for implantation in the body which can be used for transferring cerebrospinal fluid is disclosed. The shunt system comprises a body having an upper and lower surface and a distal and proximal end. The body includes a central cavity through the upper surface at a first and second port. A proximal fluid flow channel extends through the proximal end of the body and opens at a third port on the upper surface. A distal fluid flow channel extends through the distal end of the body and opens at a fourth port on the upper surface. A resilient dome comprised of a self-sealing material is attached to and extends over the upper surface of the body. A first portion of the resilient dome extends over the first and third ports on the upper surface defining a first chamber. The first portion of the resilient dome cooperates upon flexing with the third port to occlude the third port. A second portion of the resilient dome extends over the second and fourth ports on the upper surface defining a second chamber. The second portion of the resilient dome cooperates upon flexing with the fourth port to occlude the fourth port.

Low profile shunt system

A catheter guide is provided which has a base having a first channel extending thereacross for receiving a catheter. An arcuately extending member extends outwardly from the base. A second channel extends along the arcuately extending member for also receiving a catheter. The first and second channels extending respectively across the base and along the arcuately extending member can be enclosed or partially enclosed for retaining a catheter within the channels and within the catheter guide.
