A removable intravascular filter having a filtering configuration for capturing thrombi in a blood vessel and a retrieval configuration for removal from the blood vessel. The filter may be implanted in a patient's vena cava and may be removed from the vena cava through the patient's jugular or femoral vein. A method of removing an intravascular filter from a patient's vena cava through the patient's femoral vein is also provided.

A multistage balloon catheter that uses a single lumen to inflate a balloon in stages is disclosed. A fluid port provides fluid communication from an inflation lumen in the balloon catheter to the inner volume of a distal balloon. The distal balloon expands as fluid in delivered to the inner volume of the distal balloon. Once inflated, the pressure continues to rise until a threshold pressure is exceeded. A pressure sensitive inflation valve provides fluid communication into an inner volume of a second balloon disposed at least partially proximal to the distal balloon. The pressure sensitive valve allows fluid communication into the second balloon once the threshold pressure is reached in the first balloon thereby inflating the second balloon.

A method of treating an intravascular site in a patient includes spraying jets of treatment fluid out of spray orifices formed in an elongate catheter body, and changing an impingement pattern of the treatment fluid on material within the intravascular site in response to a torque induced by a back pressure of the jets. A thrombolysis catheter includes an elongate catheter body having a plurality of spray orifices formed in a body wall, and communicating with a fluid lumen longitudinally extending in the elongate catheter body. The plurality of spray orifices define a torque inducing spray jet pattern, whereby a back pressure of spray jets exiting the spray orifices induces a torque on the elongate catheter body.

An intravascular filter configured for upstream or downstream retrieval and a method for retrieving an intravascular filter from a patient's vena cava through the patient's femoral vein. The filter includes a downstream hub, an upstream hub, a plurality of primary struts extending from the downstream hub to the upstream hub, a plurality of secondary struts extending upstream from fixed ends housed in the downstream hub to free ends, secondary strut eyelets disposed at the free ends of the secondary struts, a loop member disposed through the secondary strut eyelets, an upstream coupling element disposed with the upstream hub, and a tether extending from the loop member to the upstream coupling element.

An infusion mechanism for treating an intraluminal site in a patient includes an infusion catheter having an elongate body with a proximal body end defining at least one fluid supply orifice, and a distal body end. The elongate body defines a high head loss lumen in fluid communication with a first set of side ports defining a proximal infusion zone. The elongate body further defines a low head loss lumen in fluid communication with a second set of side ports defining a distal infusion zone.
