|20140081134||MULTI-LUMEN CATHETER - A catheter comprising a first lumen for receiving a guidewire and having an exit opening at a distal tip of the catheter. A second lumen, adjacent the first lumen and separated from the first lumen by a common wall, the second lumen configured for receiving contrast fluid, wherein perforations are formed in the common wall; a guidewire in the first lumen the guidewire being configured to be capable of advancement distally to extend out of the exit opening, the guidewire having two conditions: a first condition in which the guidewire is advanced distally to block the perforations whereby fluid may not flow from the second lumen to the first lumen; a second condition in which the guidewire is withdrawn proximally to unblock the perforations whereby fluid may flow from the second lumen into the first lumen and thence out of the exit opening.||03-20-2014|
|20130165903||METHOD AND APPARATUS FOR CONTROLLED OCCLUSION - A controlled volume inflation-deflation device to inflate a balloon to occlude a blood vessel by dialing a knob that locks at rotational positions to locate a plunger at equally spaced locations within a syringe of the inflation-deflation device. The inflation-deflation device includes a releasable latch to lock the proximal and distal housings together to hold the plunger forward for occlusion, and to separate and hold the proximal and distal housings to retract the plunger for perfusion. When the inflation-deflation device is returned to the latched position, the balloon is re-inflated to its previous occlusive diameter. Also, an extension tube made of a lower modulus outer material co-extruded over and miscible with a higher modulus inner material may be used to produce a suitably low compliance extension tube for the inflation-deflation device. The balloon may have tapered ends and a cylindrical center portion so that it increases by more equal increments in outer diameter in response to incremental equal increases in inflation volume.||06-27-2013|
|20120203174||METHOD AND APPARATUS FOR DELIVERING AN AGENT TO A KIDNEY - A method is described including introducing a delivery device to a point within a renal artery or a renal segmental artery and delivering a treatment agent from the delivery device according to conditions that create a turbulent blood flow and wherein the treatment agent is capable of inhibiting a biological process contributing to nephropathy. In other embodiments, an apparatus and kit are described including a delivery device for insertion to a point within a renal artery or renal segmental artery and delivery of a treatment agent capable of inhibiting a biological process contributing to nephropathy.||08-09-2012|
