ABSTRACT:
The invention provides an universally applicable transfer device for material such animal sperm or embryos to be implanted, having a catheter covered by a sleeve which is generally discarded after use and which is detachably held in place by a clamp, more especially an eccentric gripping device at the proximal end of the catheter. The design of the sleeve end is unimportant. At the distal end the sleeve tapers conically and externally it has a shaped member securing the conical form and a rounded form. The shaped member is mounted on the wall material of the sleeve. The external shaped member may be supplemented by an internal shaped member so that the distal sleeve end is gripped between the two. A cutting means integrated in the device ensures that the cartridges are cut accurately in the desired plane.
