The invention provides a catheter for use in combination with an elongate support member. The catheter comprises an elongate body having a proximal portion, a proximal end, a distal portion, a distal end, and a main shaft; an element disposed on the distal portion of the elongate body, the element being an interventional element or a delivery element for delivery of an interventional element; at least one lumen dimensioned to receive the elongate support member; and a tube wall disposed about the lumen. The tube wall has at least one removable segment disposed on the proximal portion of the elongate body and at least one non-removable segment disposed on the distal portion of the elongate body, the removable segment is tubular or generally tubular having a partial circular circumferential cross section, and the transverse cross-sectional area of the removable segment does not comprise the entire transverse cross-sectional area of the catheter. |
