A conveying device for body fluid includes a catheter tube having a distal end to be inserted into the body and a proximal end. In order to provide a conveying device which can no longer become clogged with coagulating substances, a hollow body which is arranged in a longitudinally moveable and/or rotatable manner in the catheter tube, extends from the distal end at least up to the proximal end, and forms a transport channel over its length extending in the extension direction of the catheter tube.

A self-cleaning suction device has a user's suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user's suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user's suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user's suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

A catheter or shaft, such as a distal access support or aspiration catheter, is provided that is configured to be advanced at least partially within a patient. The catheter or shaft may include a flexible and hollow shaft including a proximal end and a distal end. The flexible and hollow shaft may include a slotted portion with a plurality of slotted openings, the slotted portion including a first segment with a first pattern of slotted openings and a second segment extending proximally relative the first segment with a second pattern of slotted openings different from the first pattern.

Methods, systems, and compositions for maintaining functioning drainage blebs to reduce intraocular pressure (IOP) of an eye being treated for glaucoma. The methods, systems, and compositions feature the combination of a minimally invasive micro sclerostomy (MIMS) procedure and the application of beta radiation to a target area. The beta radiation can function to inhibit or reduce the inflammation and/or fibrogenesis that typically occurs after a MIMS procedure and leads to hole and/or bleb failure. By reducing inflammation and/or fibrogenesis, the MIMS holes and/or blebs can remain functioning appropriately.

A body cavity drainage device includes a drainage tube with a distal end configured for insertion into the body cavity of a patient, a fluid outlet at a proximal end of the drainage tube; and an activation apparatus coupled to the drainage tube between the proximal end of the drainage tube and the distal end of the drainage tube. The activation apparatus may be configured to alter a position of the distal end of the drainage tube in response to an input at a control device of the activation apparatus, and a first portion of the drainage tube extending from the activation apparatus toward the distal end may be at least substantially coaxial with a second portion of the drainage tube extending from the activation apparatus toward the proximal end. Methods relate to forming a body cavity drainage devices.

Some embodiments are directed to a system 10 for the application of topical negative pressure therapy to a site 18 on the body of a mammal. Some embodiments of the system 10 comprise a piston 22 and cylinder 24 device 12 having a self-contained power source for the generation of a reduced pressure and for aspirating the site 18. Some embodiments of the system 10 comprise a dressing 14 sealably surrounding the site 18 that can be operably connected to the device 12 by a conduit means 16 to apply the reduced pressure to the site 18.

Devices, systems, and methods for use with suction within a mammalian body. In an exemplary embodiment of a device of the present disclosure, the device comprises one or more of the following: an inner tube, an outer tube, and a foldable portion, whereby movement of the two tubes relative to one another causes the foldable portion to form a suction cup, and conversely causes a suction cup to form a foldable portion, depending on the direction of relative movement.

A body cavity irrigation and drainage system including a catheter apparatus that has a proximal end, a distal end, a longitudinal axis, a first flow channel extending from the proximal end to the distal end, and a second flow channel extending from the proximal end to the distal end and being fluidly isolated from the first flow channel. The catheter apparatus may alterable between: (1) a first state in which the first and second flow channels are linear and parallel to the longitudinal axis along an entire length of the first and second flow channels; and (2) a second state in which a distal portion of the first flow channel curls away from the longitudinal axis in a first direction and a distal portion of the second flow channel curls away from the longitudinal axis in a second direction that is different from the first direction.

An aspiration system for aspirating blood clots from a human body has a power source, an aspiration pump, and an electrical motor coupled to the power source and the aspiration pump, wherein the aspiration pump is pulsed at a frequency below 10 Hz.

The present invention pertains to use of sodium diacetate (NaHAc.sub.2) as an antimicrobial agent against bacteria growing in biofilms. The aspects of the invention include a wound care product comprising sodium diacetate, a kit comprising a wound care product, and a method of treating an infected wound.
