Abstract
An elongate steerable implement is disclosed, which may be either a steerable guidewire or catheter for coronary angioplasty applications. A floppy steerable tip on a steering region at the distal end of the implement and a control device at the proximal end are connected by means of a plurality of axially movable deflection wires extending throughout the implement. Manipulation of the control permits deflection of the steering region throughout a full 360.degree. range of motion about the axis of the implement, without axial rotation or 'torquing' thereof.
