Abstract
Sphincterotomes and methods for making and using sphincterotomes are disclosed. An example sphincterotome may include an elongate shaft having an outer surface and a distal end region. The sphincterotome may also include a sphincterotome wire assembly having a distal end coupled to the distal end region of the elongate shaft and a body portion extending along the outer surface of the elongate shaft. The sphincterotome wire assembly may be designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration. The body portion of the sphincterotome wire assembly may include a cutting region and a non-conductive region.
Claims20
A sphincterotome, comprising:
- an elongate shaft having an outer surface and a distal end region;
- a sphincterotome wire assembly coupled to the elongate shaft, the sphincterotome wire assembly including a first member and a second member;
- wherein the first member includes a cutting region disposed along the outer surface of the elongate shaft and a first proximally-extending region;
- wherein the second member includes a non-conductive region disposed along the outer surface of the elongate shaft and a second proximally-extending region;
- a joint member disposed between and coupling the cutting region of the first member with the non-conductive region of the second member;
- and
- wherein the sphincterotome wire assembly is designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration.
A sphincterotome, comprising:
- an elongate shaft having an outer surface and a distal end region;
- a sphincterotome wire assembly coupled to the elongate shaft, the sphincterotome wire assembly including a first member and a second member;
- wherein the first member includes a cutting region disposed along the outer surface of the elongate shaft and a first proximally-extending region;
- wherein a transition between the cutting region and the first proximally-extending region is defined adjacent to a distal port formed in the elongate shaft;
- wherein the second member includes a non-conductive region disposed along the outer surface of the elongate shaft and a second proximally-extending region;
- a housing member disposed between and coupling the cutting region of the first member with the non-conductive region of the second member;
- and
- wherein the sphincterotome wire assembly is designed to shift the distal end region of the elongate shaft between a first configuration and a curved configuration.
A sphincterotome, comprising:
- an elongate catheter shaft having an outer surface and a distal end region;
- a sphincterotome wire assembly coupled to the elongate catheter shaft, the sphincterotome wire assembly including a first wire and a second wire;
- wherein the first wire is a conductive wire having a cutting region disposed along the outer surface of the elongate catheter shaft and a first proximally-extending region;
- wherein the second wire is a non-conductive wire having a non-conductive region disposed along the outer surface of the elongate catheter shaft and a second proximally-extending region;
- a housing member disposed between and coupling the cutting region of the first wire with the non-conductive region of the second wire;
- and
- wherein the sphincterotome wire assembly is designed to shift the distal end region of the elongate catheter shaft between a first configuration and a curved configuration.
