An elongate element, in particular a catheter, has a curved shape imparted to its end by a device comprising razor blades which are mounted on a pivotal linkage mechanism. Upon pressing actuator members against the restoring force of spring elements, the razor blades are constrained by the pivotal linkage mechanism to follow a desired curved path.

The present disclosure provides apparatus and methods for removing thrombus outside of a hemodialysis. The hemodialysis catheter comprises an elongate shaft comprising a plurality of lumens. A first lumen has a first distal port. The first lumen is configured for the flow of a fluid in a first direction. A second lumen has a second distal port proximal to the first distal port. The second lumen is configured for the flow of the fluid in a second direction opposite to the first direction. A third lumen has a third distal port proximal to the second distal port. An elongate device is disposed through the third lumen. The elongate device has an operable member on a distal end or a device to connect to an operable member disposed on the elongate shaft. The operable member is configured to engage and remove thrombus from an exterior surface on the elongate shaft.

A vascular occlusion device for occluding a body cavity. The device includes an elongate member having an inflation lumen, an occlusion lumen, and a first portion extending distally from a proximal end and a second portion extending distally from the first portion to the distal end. An inflatable proximal balloon is disposed about the first portion and an inflatable distal balloon is disposed about the second portion. The inflation lumen is configured to inflate at least one of the balloons. The occlusion lumen is configured to introduce an occlusive material into the body cavity by way of an occlusion port located between the two balloons to occlude the body cavity. In some examples, the body cavity includes a patent foramen ovale.

In at least one embodiment of the present invention, a catheter for insertion into a patient's body is provided. The catheter comprises an elongated member having a proximal portion extending to a distal portion. A lumen is formed through the proximal and distal portions. The elongated member is formed of a polymeric material including shape memory polymers having a first phase transition temperature and a second phase transition temperature that is less than the first phase transition temperature but is greater than about room temperature. The elongated member has a first configuration at about room temperature for insertion into the patient's body and self-configures to a second configuration at a first temperature of at least the second phase transition temperature for fluid communication with the patient's body. At least a portion of the lumen has a larger flow area in the second configuration than in the first configuration.

In at least one embodiment, a catheter for insertion into a patient for providing treatment is provided. The catheter comprises an elongated shaft having a proximal portion extending to a distal portion. The proximal portion has a plurality of first lumens formed therethrough and at least one septum separating the first lumens in non-coaxial relationship with each other. The first lumens each have an associated flow area for providing the treatment through the proximal portion. The distal portion has a second lumen in fluid communication with the first lumens. The septum terminates distally in the proximal portion to merge the first lumens with the second lumen. The second lumen has a second flow area that is greater than any one of the associated flow areas of the first lumens for providing the treatment to the patient.

An endobronchial blocker catheter for use in blocking a selected mainstem bronchus under guidance of a bronchoscope. The endobronchial blocker catheter comprises a tubular assembly and an elongated body that receives the tubular assembly. The tubular assembly comprises a tubular member and a loop disposed at a distal end of the tubular member. The loop is sized such that the bronchoscope is passable through the loop. The elongated body has a plurality of lumens therein, and an inflatable blocker balloon disposed about a distal portion of the elongated body. One of the lumens extends to an interior of the balloon to accomplish inflation of the balloon for retaining the blocker catheter in the mainstem bronchus, and another lumen is sized for receiving the tubular assembly in a manner such that the loop extends from a distal end of the elongated body. The blocker catheter is guided by the bronchoscope to the desired inflation site via the loop.

A vascular occlusion device for occluding a body cavity. The device includes a tubular scaffold extending from a proximal end to a distal end. The scaffold is formed from a plurality of interconnected and articulated members configured to self-expand into an open configuration. A plurality of barbs extend from the articulated members, each barb including an anchoring end. The anchoring end is disposed radially outward from the scaffold in the open configuration and adapted to embed into the cavity walls. A radially expandable substance is disposed within a device lumen. The substance is configured to promote body tissue growth within the body cavity to occlude the body cavity. In one example, the body cavity includes a patent foramen ovale.

A catheter assembly includes a multi-lumen catheter and fluid supply apparatus for supplying fluid to said multi-lumen catheter. The fluid supply apparatus includes an inlet element for coupling to a supply of catheter fluid, a plurality of fluid outlet elements arranged to be each coupled to a respective lumen of the catheter and a flow splitter arranged between the inlet element and the outlet elements. The flow splitter is able to split or divert flow of fluid from the inlet to at least one of the plurality of outlets. For this purpose, the preferred embodiment includes a gate for directing fluid flow to one or more of the outlet elements. There may also be provided a diffuser and a nozzle.
