First Claim
Patent Images
1. A catheter head for introducing a fluid into an organic tissue, said catheter head comprising:
- a) a cannula casing comprising a cannula protruding on one side of said cannula casing and a passage channel running through the cannula casing and connected to said cannula;
b) a connecting element which includes a fluid supply and can be connected to the cannula casing in such a way that said fluid supply is connected to said passage channel;
c) a guiding means formed jointly by the cannula casing and said connecting element, for positioning and guiding the connecting element relative to the cannula casing; and
d) a fixing means for detachably fixing the connecting element to the cannula casing;
wherein e) said guiding means for positioning the connecting element relative to the cannula casing exhibits a number of selectable, discrete rotational positions about the longitudinal axis of the cannula; and
f) said fixing means detachably fixes the connecting element, positioned in a rotational position, to the cannula casing in said selected rotational position.

Abstract
A catheter head, for introduction of a fluid into an organic tissue, including a cannula housing with a cannula, a connector element with a fluid inlet, a guide and a fixing device. The guide device has several selectable discrete rotational positions for positioning the connector element relative to the cannula housing about a longitudinal axis of the cannula. The connector element, positioned in a rotational position, is detachably connected to the cannula housing in the selected position by means of the fixing device.

19. A catheter head comprising:
-
a casing comprising a cannula extending from said casing and a passage channel extending generally through the casing and coupled to said cannula;
a connecting element comprising a fluid pathway, said connecting element connectable to the casing whereby said fluid pathway is connectable to said passage channel;
means formed jointly by the casing and said connecting element for guiding the connecting element relative to the casing; and
means for detachably fixing the connecting element to the casing;
whereinsaid means for guiding exhibits selectable, discrete rotational positions generally around the cannula, and said means for fixing is used to selectively fix the connecting element to the cannula casing in a selected one of said rotational positions. - View Dependent Claims (20, 21, 22, 23)
