Abstract: A medical device including an elongate member having a proximal end, a distal end, and at least one lumen extending therebetween. The medical device may also include at least one proximal control member extending within the elongate member from the proximal end to the distal end of the elongate member, a coupling mechanism disposed adjacent a distal portion of the elongate member, and an end-effector removably coupled to the distal end of the elongate member, wherein the end-effector includes at least one distal control member extending proximally therefrom, and wherein the coupling mechanism is configured to removably couple the at least one distal control member to the at least one proximal control member.

Abstract: Systems and methods for providing a precision-notch shape in a flexible medical catheter are disclosed. The system comprises a clamp punch die assembly, a clamping device, and a knife-edge punch die. A catheter blank can be inserted in a clamp die about a die pin. The clamping device forces together upper and lower portions of the clamp die, which causes the clamp die to restrain the catheter blank against the die pin. Once the catheter blank is restrained, a punch die with one or more finely-honed blades passes through a notched region in the clamp die and a notched area in the die pin without contacting either to provide the precision-notched portion in the catheter blank. The restraint provided by the clamp die minimizes rotation of the catheter blank, which prevents tearing and excess flashing.
