摘要： A device and system for providing a centered lumen within a catheter body. A coiled guide lumen (CGL) is composed of a length of wire forming a plurality of coils about the longitudinal axis of the CGL, the CGL including one or more first sections having a first diameter and one or more sections having a second diameter, the second diameter being greater than the first diameter, and a secondary guide lumen extending through the first sections. The CGL may include at least one pull wire extending through the secondary guide lumen and attached at the distal portion of the catheter body. A band may be coupled to an interior of the catheter body distal portion, each of the pull wires being coupled to the annular band. Alternatively, the system may further include a shim coupled to the band, each of the pulls wire being coupled to the shim.

摘要： A catheter has a metal deflection beam with rectangular cross-section and one or two fiber puller members for predictable on-plane bi-directional deflection. Each fiber puller member is anchored at its distal end to a respective surface of the beam by a metal ferrule that is crimped onto the distal end. The ferrule is shaped to provide a flat outer underside that can lie flat against a beam surface and a thin planar distal section that is welded to the beam. With a distal end of the beam sandwiched between the thin planar distal section of two ferrules, the ferrules and the beam can be welded together by a single laser pulse.

摘要： A delivery system and method for delivering a prosthetic heart valve to the aortic valve. The system includes a delivery catheter having a steering mechanism thereon for delivering a balloon-expandable prosthetic heart valve to the aortic valve through an introducer passing into the left ventricle through its apex. The introducer may have a more floppy distal section than a proximal section to reduce trauma to the heart wall while preserving good operating field stability. The delivery catheter includes a deflecting segment just proximal to a distal balloon to facilitate positioning of the prosthetic heart valve in the proper orientation. A trigger in a catheter handle may be coupled to a deflection wire that actuates the deflecting segment, while a slider in the handle controls retraction of a valve pusher. The prosthetic heart valve may be installed over the existing calcified leaflets, and a pre-dilation valvuloplasty procedure may also be utilized.

摘要： The catheter has a catheter body and a deflectable section with a flat deflection beam having a different deflection initiation location on each side of the beam to provide nonsymmetrical bi-directional deflection via a single continuous puller wire with two longer parallel segments connected by a U-bend segment anchored at a distal end of the beam. A spacer is provided on each side of the beam to guide and bind the respective puller wire segments and maintain a predetermined separation distance between the puller wire and the beam, including a neutral bending axis of the beam, for reducing the beam's bending moment. One or more heat shrinking tubes may surround the spacer and the beam to tightly constrain the puller wire to the beam.

摘要： A deflectable catheter including an outer member having a proximal portion and a distal portion, an elongated column member extending distally from the outer member and an inner member positioned coaxial with the outer member and attached to the column member. The inner member extends distally of the outer member and has a distal tip portion. A reinforcement member is positioned over the column member to restrict axial movement of the column member such that when one of the inner member or outer member is moved with respect to the other, axial compression of the column member is restricted by the reinforcement member causing the distal tip portion of the inner member to deflect laterally.
