Patent number: 8206372Abstract: A tubular transition member having an annular wall with at least one cut extending through the annular wall is disclosed for controlling a transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member may extend across the junction formed between the stiffer proximal section and the more flexible distal section. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.Type: GrantFiled: June 3, 2010Date of Patent: June 26, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Christopher R.

Patent number: 6475209Abstract: A spiral cut transition member is disclosed for controlling the transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member has a spiral cut provided therein to vary the flexibility of the transition member over its length. The pitch of the spiral cut can be varied to facilitate a gradual transition in flexibility along the catheter. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.Type: GrantFiled: March 24, 2000Date of Patent: November 5, 2002Assignee: SciMed Life Systems, Inc.Inventors: Christopher R.
