Abstract

A catheter device is provided including a catheter element and a flexible plate element wherein the catheter element has a body inserting section extending from one side of the flexible plate element and a tube connecting section extending from the other side of the flexible plate element, the tube connecting section being attached to the flexible plate element with the through bore thereof being generally parallel to or at an acute angle to a plane passing through the flexible plate element.

Claims

1. A trocar catheter for use in penetrating body cavities including:

a one-piece catheter device including a flexible plate element, a catheter tube extending from one side of the flexible plate element and a curved flexible elbow section extending from the other side of the flexible plate element and having a through bore which communicates with the through bore of said catheter tube, means to permit the through bores of said catheter tube and flexible curved elbow section to be held and aligned including having a curved elbow section flexibly mounted on a portion of said plate element of said catheter device, and a rigid trocar slidably and removably received within the curved elbow section and catheter tube to align the communicating through bores thereof.

2. The trocar catheter as defined in claim 1 wherein said flexible plate element defines a means for providing a straight bore and for gripping said plate element and said hub to facilitate the introduction of said trocar in one position and to mount said catheter on the body in a second position including grooves formed said plate on opposite sides of the curved elBow section to provide a pair of flexible selectively positionable wing elements.

3. The trocar catheter as defined in claim 2 wherein said curved elbow section is attached to one of said flexible wing elements.

4. The trocar catheter as defined in claim 1 and further including an inside catheter device having a catheter tube section adapted to be inserted within the curved elbow section and catheter tube of said one-piece catheter device and a valve attachment including a male fitting complementarily shaped relative to the through bore of said elbow section for releasably locking engagement therewith, said valve attachment being provided with a valve element for opening and closing the communicating through bores of said catheter tube and curved elbow section when said valve attachment is releasably locked within said curved elbow section.

5. The trocar catheter as defined in claim 4 and further including an integral strap and plug element attached to said flexible plate for plugging off the communicating through bores of said catheter tube and curved elbow section.
