  • Patent number: 8343105
    Abstract: The present invention relates to a multi-size catheter for use in biliary endoscopic procedures. The multi-size catheter comprises an outer diameter defined by a plurality of superimposed peelable layers. The peelable layers allow the multi-size catheter to function as a single operator exchange catheter without the need, and additional expense, of an endoscope sheath. Before positioning the multi-size catheter within the working channel of an endoscope, the peelable layers may be selectively removed in order to obtain an outer diameter for the catheter that is less than, but approximate to, the inner diameter of the working channel of the endoscope. The resulting fit eliminates the potential for a guidewire to slip out of the guidewire channel and become pinched between the catheter and the endoscope working channel. With an incorrect fit, a pinched guidewire would restrict the desired movements of both the guidewire and the catheter.

  • Patent number: 8298178
    Abstract: A rapid exchange catheter extends from a proximal portion which remains outside of a patient's body during use to a distal portion which, during use, is located within a body lumen adjacent to a target area to be treated, wherein the proximal and distal portions are coupled by a medial portion. The catheter comprises a guide wire lumen extending longitudinally through the distal portion and a guide wire receiving channel formed by an outer surface of the medial portion, wherein the guide wire lumen is open to a distal end of the channel.

  • Patent number: 8043208
    Abstract: An insertion tool for use in inserting a guide wire into a guide wire lumen of a catheter for use in a lumen of an endoscope. The insertion tool includes a main body having a main lumen and a funnel-shaped extension connected to and disposed atop the main body. The funnel-shaped extension having a funnel lumen. The funnel lumen has a top opening and a bottom opening. The funnel lumen tapering from the top opening to the bottom opening. The bottom opening positioned and sized to communicate with the guide wire lumen of the catheter such that, when the catheter is disposed in the main lumen, the guide wire may be easily inserted into the top opening of the funnel lumen and into the guide wire lumen of the catheter.
