A catheter devices/systems and methods therefrom are described herein for treating acute kidney injury, especially the contrast-induced acute kidney injury wherein the devices prevent the contrast dyes from entering into kidney and/or facilitate blood flow of kidney by said catheter system.

A catheter has a lumen body having a distal end and a proximal end. A hub is connected to the proximal end. The hub includes a luer connection and a vacuum port assembly.

Disclosed are compositions, dispensers, and methods thereof for establishing a urine passageway through a ureter. For example, a composition can include, in some embodiments, a primary solid phase and a secondary solid phase. The primary solid phase can include a monomer, a pre-polymer, or a mixture thereof configured to commence polymerization into a polymeric form in the ureter when contacted with a fluid such as urine or saline. The secondary solid phase is dispersed in the primary solid phase. The secondary solid phase can include a leachable component. The leachable component is configured to leach from the polymeric form when contacted with a sufficient amount of a same or different fluid. The leachable component is also configured to form pores of an open-pore network throughout the polymeric form when leached from the polymeric form, thereby establishing the urine passageway through the ureter.

A catheter including a tubular catheter body defining a distal portion, a distal end and a lumen that extends to the distal end, a radiopaque marker carried within the lumen, and a non-metal tip that is bonded to distal end of the catheter body.

A kit including a sheath having a tubular body with proximal and distal ends, an axis extending between the ends and a wall defining a bore extending along the axis to the distal end of the body. A delivery tube having proximal and distal ends and a lumen is adapted for disposition within the bore of the sheath in sealing engagement with the sheath, the delivery tube being slideable distally relative to the sheath. An elongated cannula having proximal and distal ends and a lumen is adapted for disposition inside the lumen of the delivery tube and an elongated dilator is adapted to fit within the lumen of the cannula with a proximal portion of the dilator extending proximally beyond the proximal ends of the cannula and delivery tube and in sealing engagement with the delivery tube proximal to the cannula.

The current document is directed to length-adjustable catheters and methods that employ length-adjustable catheters to treat malformations, constrictions, obstructions, lesions, and blockages within patients' blood vessels. The length of the shaft of a length-adjustable catheter, to which the current application is directed, can be adjusted over a range of lengths prior to and during medical procedures. In many implementations, length adjustment is accompanied by indications, to the medical provider, of the extent of a length adjustment. The indications may include one or more of visual markings, haptic feedback, radio-opaque markings, and/or other types of indications. In many implementations, the variable-length mechanism of the length-adjustable catheter is mechanically lockable following length adjustment.

The invention provides an introducer assembly for delivering a blood pump into vasculature of a subject, as well as a method for utilizing the assembly.

An operable implant adapted to be implanted in the body of a patient. The operable implant comprising an operation device and a body engaging portion, the operation device comprises an electrical motor comprising a static part comprising a plurality of coils and a movable part comprising a plurality of magnets, such that sequential energizing of said coils magnetically propels the magnets and thus propels the movable part. The operation device further comprises an enclosure adapted to hermetically enclose the coils of the static part, such that a seal is created between the static part and the propelled moving part with the included magnets, such that the coils of the static part are sealed from the bodily fluids, when implanted.

To provide a stent capable of preventing reclosing granulation. Provided is a stent including a cylindrical body part 3 and a tip portion 5 positioned at the tip of the body part 3, wherein the closer to the tip the tip portion 5 gets, the larger the width of the tip portion 5 becomes.

Endovascular drug delivery systems and methods are disclosed herein for delivering a therapeutic agent to the intracranial subarachnoid space of a patient, and/or deploying an endovascular drug delivery device distal portion in the intracranial subarachnoid space and a portion of the drug delivery device body in a dural venous sinus such that a therapeutic agent is delivered from the deployed drug delivery device into the intracranial subarachnoid space.
