Abstract: Systems and methods for treating a stricture, for example along the biliary and/or pancreatic tract, are disclosed. An example system may include a handle (14) having a base, a first carriage (26) translatable relative to the base, and a second carriage (24) translatable relative to the base. A sheath (16) may be coupled to the first carriage. The system may also include a catheter shaft (12) having a proximal end region and a steerable distal end region. The proximal end region may be coupled to the second carriage. A needle may be releasably coupled to the handle. The needle may be configured to pass through tissue into a position along the biliary and/or pancreatic tract. The system may also include a steering member (44) having a first end coupled to the steerable distal end region of the catheter shaft and a second end disposed adjacent to the handle.

Abstract: An electrophysiology catheter (100) comprising a tubular shaft (102), the shaft having a proximal portion, a distal portion having a distal end and a deflection region (108), the shaft defining a longitudinal axis and including an outer tubular jacket (402), and articulation member (404) disposed within the jacket in the deflection region, the articulation member comprising a plurality of longitudinally-arranged tubular segments (502), a plurality of first connecting segments (504), and a plurality of second connecting segments (506), wherein adjacent tubular segments are joined by respective ones of the first and second connecting segments, and wherein all of the first and second connecting segments are disposed in a first plane extending through the longitudinal axis. A first reinforcing member (508) and a second reinforcing member (510) extend through the plurality of first and second connecting segments, respectively.

Abstract: A guidewire (10) for use along the biliary and/or pancreatic tract. The guidewire includes an elongate core member (12) having a proximal end region and a distal end region. A coil member (14) is disposed along the distal end region. An actuation member (20) is coupled to the coil member. The actuation member is configured to shift the coil member between a first configuration and a compressed configuration. The coil member is configured to be advanced across a biliary and/or pancreatic stricture when in the compressed configuration. A sleeve (18) is disposed over the coil member.
