Abstract: Systems and methods for delivering multiple embolization coils to a location within the body of a patient are disclosed. In one embodiment, a coil delivery system has coil deployment members coupled to embolization coils and is arranged for independent movement of the embolization coils. In some exemplary embodiments, the disclosure provides coil delivery systems in which the embolization coils are positioned within different lumens and/or on different straightening members. Methods and other embodiments are disclosed.

Abstract: A multilumen catheter with an inflow or an outflow lumen having at least two tube extensions extending from the distal end of the catheter that open into the inflow or outflow lumen. The catheter is useful in the extracorporeal treatment of blood, such as hemodialysis, hemofiltration or apheresis. A device to selectively test each of the two tube extensions for occlusion.

Abstract: Devices, systems and methods are disclosed for providing a direct visual indication of the relative inflationary condition of the balloon on a balloon catheter after insertion into the patient. In certain exemplary embodiments, a gastrostomy tube catheter is disclosed having a fluid feeding lumen and a balloon inflation lumen, a balloon communicating with the balloon inflation lumen, and an indicator strip having one end fixedly attached to the balloon and a free end movable along the length of the tube in accordance with the relative inflation and deflation of the balloon. The presence of the free end of the strip along an exposed portion of the gastrostomy tube serves as a direct visual indicator of a deflated condition of the balloon.

Abstract: Among other things, a catheter assembly including a main catheter portion and a deformable tip portion is disclosed. Embodiments of the catheter have a lumen extending between distal and proximal ends. The deformable portion is configured to transform from a compact shape to an expanded shape when it is inserted into a patient. The cross-sectional sizes and shapes of the deformable portion and catheter are similar or about the same; therefore, the compact shape mimics a traditional distal tip of a catheter during insertion into a patient. The physician can use a standard catheter insertion technique. As the deformable portion warms to the patient's body temperature, the deformable portion bulges to the expanded shape. The expanded shape helps attain laminar flow and increases the flow rate through the catheter. To activate the deformable portion to return to the compact shape, cold liquid is passed through the deformable portion.
