Claim:
A tool for cutting a tubular sheath of a guide-catheter along a generatrix of said sheath in the presence of a lead placed in an internal lumen of this sheath, said tool comprising a blade holder body having a roughly flattened shape able to be held between the fingers of a user and a median plane, said blade holder comprising: a cutting area, and a blade presenting a cutting edge roughly lying in the median plane of the blade holder body, wherein said cutting edge is directed toward the outside of the blade holder body following a cutting direction (X) corresponding to said generatrix of the sheath to be cut, and a straight tubular guide, roughly parallel to the cutting direction, said tubular guide being able to receive the lead at an open side, opposite to the blade, and being able to receive the guide-catheter at the blade side, a prehension area adjacent the cutting area and level with the rear of said cutting area, the prehension area having a first side and a second side opposite the first side, the first side further comprising a first concave footprint formed for receiving the thumb of the user, and the second side further comprising an area for receiving the forefinger of the user, and a holding pathway for the lead disposed in the prehension area, said holding pathway comprising at least a curved area crossing through and through the first footprint and in the continuation of the tubular guide and following an overall orientation presenting an angle with said tubular guide, wherein said tool is further characterized by: the minimal distance between the blade and the contour of said first footprint being less than or equal to 20 mm, and the lead holding pathway in the prehension area further comprises an “S” shaped pathway comprising at least a first curved area and a second counter-curved area.
