摘要： A catheter includes an elongate body having first and second chambers extending within the elongate body from a proximal end to an intermediate section, the first chamber having a first opening and the second chamber having a second opening at the intermediate section. The catheter also includes a valve structure that may have first and second barrier elements to open or close the first and second openings, respectively. The first and the second barrier elements may be coupled by a connecting structure moving within an opening in a guide structure. Alternatively, the first and the second barrier elements may be coupled in a U-shaped structure that moves over the guide structure. To permit flushing of the chambers when the first and second openings are closed, the first and second chambers may also be connected by a connecting channel defined by an opening in a wall of the elongate body.

摘要： A catheter with a distal end comprising a substantially planar surface and two openings separated by a septum on the substantially planar surface, each corresponding to separate lumens. First and second longitudinal slots are formed in the distal end, opening on the substantially planar surface and communicate with the interiors of corresponding, separate lumens, respectively. Wherein each slot has a length and a width, relative to the dimensions of respective lumens and the rate of blood flow to be passed through the catheter, such that (i) when a given lumen is to be used for a return function, the primary blood flow will exit the opening of that lumen, and (ii) when a given lumen is to be used for a suction function, the primary blood flow will enter the proximal end of the longitudinal slot associated with that lumen, minimizing undesirable recirculation of dialyzed blood.

摘要： A catheter device has an elongate body and a chamber positioned within the elongate body. The chamber has a chamber opening, and a barrier, such as a gate, moves over the chamber opening. The barrier moves between an uncovered position uncovering the chamber opening and a covered position covering the chamber opening. The catheter has at least one cutting edge by the chamber opening. In particular, the at least one cutting edge may be on the barrier, where the at least one cutting edge is guided over the chamber opening with movement of the barrier between the uncovered position and the covered position. The cutting edge cuts away a fibrin sheath blocking the chamber opening. The catheter may have multiple chambers connected by channels that allow the chambers to be flushed to prevent microbial colonization.

摘要： An improved implant device is deployed a vessel, or passageway, in a body with an attachment mechanism that permits stable and secure positioning of an implant device while also permitting easy removal without damaging the vessel. In particular, clip-like structures are used to engage the wall of the passageway. A tether that works in cooperation with the attachment mechanism may be used to facilitate removal of the implant device after an indicated period. The tether is removable from the implant device to convert the implant device into another configuration, which can remain permanently or be removed at a later time. Moreover, a centering mechanism may be employed to ensure that the implant device is properly oriented within the passageway when deployed.

摘要： A method and apparatus for anchoring a medical implant device after the devi ce has been brought to rest at a desired position within a blood vessel or othe r body passageway. An anchor delivery system (22) is provided which houses one or more uniquely configured expandable anchors (28) which are connected to t he medical implant device (10). The anchors (28) remain housed in a non expande d configuration until after the medical implant device (10) has come to rest i n a desired position within the body, and then the anchors (28) are positively propelled through a body wall (12) from a first side to a second side where each anchor (28) expands outwardly on opposite sides of an anchor shaft (18) . To positively propel the anchors (28), a drive shaft (50) extends back to a triggering unit (68) which, when activated, causes the drive shaft (50) to drive the anchor shafts (18) in a direction which results in propulsion of t he anchors (28) through the body wall (12).
