  • Publication number: 20210100610
    Abstract: A conductive coating may be adhered to a structure comprising a hydrophobic and/or adhesion-resistant surface. The conductive coating may have a polymer backbone with conductive particles suspended in the backbone. In some embodiments, the conductive coating may be applied directly to the surface. In other embodiments, the conductive coating may be indirectly applied by first applying a primer adhesive to the outer surface, and then applying the conductive coating over the primer adhesive. An example structure may be a catheter of an endoscopic medical device, such as a bipolar sphincterotome, where the conductive coating functions as a return electrode.

  • Publication number: 20200101271
    Abstract: An expandable dilation member may include a proximally-tapered portion to dilate a stricture. The dilation member may be distally advanced in an unexpanded state over a wire guide through the stricture. The dilation member may then be configured in an expanded state, where the dilation member has a longitudinal profile that includes the proximally-tapered portion. A handle assembly proximally pulls the dilation member in the expanded state. In response, the proximally-tapered portion engages with and biases the stricture. When biasing the stricture, the proximally-tapered portion exerts a plurality of different types of forces, including a shearing force, a radial force, and in some procedures, a torsional force. In some embodiments, the proximally-tapered portion has a continuous taper from a smallest diameter to a largest diameter. In other embodiments, the proximally-tapered portion has at least one constant-diameter portion longitudinally disposed in between the smallest diameter and the largest diameter.
