Abstract: A kit for the withdrawal of a blood vessel filter of the umbrella type formed from a bush (31) serving as a sleeve for retaining a number of flexible strands (32) that spread apart naturally and end in hooks (33) directed outwards so that they lock onto the wall of a vessel, comprising a first so-called “external” catheter (1) a stem that can be inserted in the external catheter and has, at one of its ends, a number of flexible legs (18) that open out from the stem, spreading apart naturally and ending in hooks (20) directed inwards for grasping bush (31) of the filter as they close up again and preferably in addition a second catheter (11), of diameter such that it can be introduced into the external catheter (1).

The system includes a relatively large pillow-like device of a size and configuration to be disposed beneath the person when lying down and having an opening therethrough in the area of the person's coccyx with a slot extending therefrom to provide for air circulation. Knee rests extend out from each side of the large pillow-like device to accommodate the person when on their side. A thigh rest is of a size to cooperate with and from an extension of the relatively large pillow-like device to accommodate the person's thighs. Scapula-elbow-arm rests are also provided for that area of the person's anatomy and each includes first and second pillow-like portions connected along a relatively thin line forming an air channel. Flaps are provided for each scapula-elbow-arm rest to connect one pillow portion to another. Elbow and heel protectors are also included in the system.
