A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.

A thrombolytic filtration and drug delivery catheter is disclosed comprising a shaft which longitudinal ribs. The ribs are compressed while being advanced to the site of interest and are released at the site, flaring to a diameter greater than the diameter of the shaft. The ribs can be compressed by a sleeve or thread, for example. Drugs or other agents can be delivered through lumens in the shaft and ribs, out through ports in the ribs. Preferably, the ports are positioned to deliver the drugs or other agents between the ribs and within the region defined by the ribs.

A catheter for delivering drugs or other agents is disclosed particularly suited for delivering drugs proximate the walls of a vessel or lumen, such as an artery or vein. The catheter comprises a shaft with a distal portion comprising at least one and preferably a plurality of delivery members. When deployed, the delivery members flare from the catheter shaft at an acute or obtuse angle. At least a portion of the delivery members are within a restraining member such as a sleeve or thread, for example, to maintain the delivery member within the diameter of the shaft prior to deployment. Delivery lumens provide drugs to ports in the delivery members for delivery out of the catheter. The delivery members preferably bear against the wall of the vessel when deployed, to deliver the drug or other agent proximate the walls of the blood vessel, where blood flow is slow. In another embodiment the delivery members comprise a first tapered portion, a second longitudinal portion and a plurality of drug delivery ports.
