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.

Anesthesia manifold and induction valve

A multi-lumen percutaneous introducer for introducing a catheter and fluids into a body lumen includes an introducer sheath having a first lumen for receiving a catheter and a second lumen within the sheath having a proximal opening for receiving fluids and a distal opening for delivering fluids into the body lumen. A port in alignment with the first lumen receives the catheter when the catheter is inserted through the first lumen into the body lumen.

Multi-lumen percutaneous introducer

The catheter insertion valve of the present invention comprises a central tubular body and a non-removable tubular cap that can be screwed onto the body wherein a bore extending through the body and the cap defines a pathway for a catheter. Such catheters are inserted into arteries, organs or body cavities for the purpose of introducing medications of instruments for treatment, diagnosis or the performing of in vivo procedures. A seal located within the central body of the valve is used to form a fluid-tight seal about the catheter, guidewire or other instrument extending therethrough. Alternatively, the seal can completely close off the pathway when it is not being used for catheter insertion thereby preventing air entrainment. The central body is provided with one or more seal position indicators to indicate to the operator that a seal has been formed about a catheter or guidewire of standard dimension. The seal is manually adjusted by rotating the non-removable cap. The cap is formed on a mold, removed prior to cooling and then reformed by annealing the cap prior to mounting onto the central body of the valve.
