Abstract
A pull wire assembly for integrating into and anchoring an end of a steerable catheter or introducer sheath used in medical procedures; it has a pull ring made at least in part from a radiopaque material that, when integrated into the end of the steerable catheter or the introducer sheath, allows for visualizing the end of the steerable catheter or the introducer sheath during a medical procedure; and one or more pull wires with a different material composition from that of the pull ring, wherein the one or more pull wires are each fused to the pull ring, wherein the fusion results in an amalgam of the radiopaque material and the pull wire material composition.
Claims19
A pull wire assembly for integrating into and anchoring an end of a steerable catheter or introducer sheath used in medical procedures, comprising:
- a pull ring made at least in part from a radiopaque material that, when integrated into the end of the steerable catheter or the introducer sheath, allows for visualizing the end of the steerable catheter or the introducer sheath during a medical procedure;
- and
- one or more pull wires with a different material composition from that of said pull ring, wherein said one or more pull wires are each fused to said pull ring, wherein said fusion results in an amalgam of said radiopaque material and said pull wire material composition.
A pull ring adapted for connecting to one or more pull wires, wherein the pull ring and the one or more pull wires provide a pull wire assembly for use in a catheter or sheath, the pull ring comprising:
- a proximal end and a distal end defining a width of said pull ring;
- an outer surface and an inner surface defining a thickness of said pull ring;
- and
- apertures distributed about said outer surface, wherein a depth of each of said apertures is at most said thickness of said pull ring,
- wherein each of said apertures is located closer to said proximal end than said distal end, and
- whereby the one or more pull wires are each joinable to said pull ring at a location closer to said proximal end than said distal end of said pull ring.
