Catheter apparatus for performing diagnostic and therapeutic modalities in the biliary tree includes a catheter with multiple lumens. A first lumen is adapted to receive a guidewire and can serve as a transport lumen for contrast agent. A second lumen carries a cutting wire for performing a sphincterotomy. A third lumen can be used as an inflation lumen for a distally located balloon. Expansion of the balloon occludes a portion of the biliary tree and allows the catheter to sweep any gallstones through the sphincter of Oddi into the duodenum.

An improved urethral cap for alleviating urinary incontinence when positioned on the body of the user is provided. The improved urethral cap includes a body portion defining an interior chamber, the chamber providing a vacuum therein to hold the urethral cap in contact with the body of the user. The cap further includes at least one flange supported by the body portion, the flange having a thickness of less than 0.75 millimeters, and preferably less than 0.5 millimeters. The improved urethral cap has increased flexibility and therefore provides increased comfort to a user when in place over the urethra.

An integrated catheter assembly for enabling diverse in situ therapies includes a catheter with an irrigation fluid lumen, a distal tip portion that acts as a hemostat and a needle for injection therapy that extends through the catheter lumen and a lumen in the distal tip portion. A needle hub structure carries the catheter and provides a sealing entrance for a needle that can be displaced between extended and retracted positions. The needle and electrodes are electrically isolated. The apparatus provides a physician the options of irrigating tissue, cauterizing tissue or injecting tissue without the need for removing the apparatus from the working channel of an endoscope.

Integrated catheter for diverse in situ tissue therapy

A catheter includes a flexible elongated catheter body that defines a needle-receiving, or probe-receiving, lumen, a retractable tissue-penetrable needle, or probe, and an electrode mounted on the distal portion of the catheter body. The needle provides a fluid passage for introducing fluid into tissue to permit the introduction of sclerotic agents for enhancing electrocoagulation of the tissue, heat-responsive drugs for improving the bonding to tissue surfaces, or vaso-constrictor drugs. The probe can also have a passage for fluid. The electrode can provide bipolar electro-coagulation of tissue in combination with an additional electrode mounted on the catheter body, or alternatively, the electrode can be employed in combination with either the needle or probe to establish a bipolar electro-coagulation path through tissue. The needle, or probe, in combination with an external electrode can be used to provide unipolar electro-coagulation, or ablation. In certain instances, the electrode can be used to provide a mapping function inside cardiac chambers.
