Abstract: The present invention relates generally a manufacturing process which results in a completely hydrogel polymer device that maintains lumen patency which allows for numerous applications. Catheters and stents are particular examples, and their composition, mechanical characteristics, and the significantly unique ability to conduct and allow fluids to pass from one end to the other without physiological rejection, inflammation, or manifestation of complications due to implant or otherwise undesirable outcomes when used for ambulatory and or therapeutic interventions is the purpose of the invention.

Abstract: A multi-lumen catheter for independent delivery and withdrawal of fluids having an improved leading end to minimize stasis and an improved coupling for connection to externally located infusion and withdrawal tubes. The improved leading end has an ellipsoidally shaped tip with a smooth, uninterrupted surface and, in close proximity to the tip, a port or ports evenly spaced along the length of each lumen in staggered relation between each lumen. The improved coupling is a generally L-shaped, implantable transition device bonded to a percutaneous access device. The overall conformation of the multi-lumen catheter may be either a "U-shape" or an upright "Z-shape." Externally located infusion and withdrawal tubes are in fluid connection with an epidermal end of the transition device and a multi-lumen tube fits snugly over nipples at a subcutaneous end of the transition device.

Abstract: A catheter based delivery system may be used for both therapeutic and diagnostic applications. The catheter based delivery system includes a catheter having a distal end. The distal end of the catheter includes several electrodes that can emit a radio frequency waveform, and may receive a signal representative of an impedance of material in the exposed to the radio frequency waveform. The radio frequency waveform may also be applied to ablate specifically targeted material exposed to the radio frequency waveform. The several electrodes may be configured as an antenna.
