Abstract: An indwelling valve actuated urinary catheter has an inner catheter having an inlet port configured on a distal end and for locating within the bladder and a sheath that extends over the inner catheter to produce a valve. The sheath extends over the inlet port when the valve is in a closed position and manipulation of a valve actuator on the proximal end, located within the penis, opens the valve. A bladder plug configured on the distal end of the inner catheter may form a seal between the catheter sheath and the inner catheter. The valve actuator may comprise a proximal nodule and a distal nodule that are configured within the urethra along the penis. Manual manipulation of the valve actuator through the penis, such as by pinching the penis, moves the proximal and distal nodules with respect to each other to open or close the valve.

Abstract: An interventional delivery system with a first catheter having at its distal end a side branch vessel segment; a second catheter attached around the first catheter and having at its distal end a main vessel segment; a side branch vessel device attached to side branch vessel segment of the first catheter; and main vessel device attached to the main vessel segment of the second catheter. The main vessel device and the side branch vessel device are able to be simultaneously delivered to a treatment site.

Abstract: A conduit, such as an introducer sheath, catheter, or guide catheter, incorporating two or more separate lumens to prevent the entanglement of guidewires located at least partially within the conduit. The lumens are separated by at least one disruptable barrier that allows multiple lumens to be converted into fewer lumens prior to or as a device is advanced through the introducer sheath.
