METHOD AND APPARATUS FOR REMOVABLE CATHETER VISUAL LIGHT THERAPEUTIC SYSTEM

A medical device assembly is provided for removable insertion into a catheter with a lumen. The medical device assembly comprises an electromagnetic radiation (EMR) source for providing non-ultraviolet, therapeutic EMR having an intensity sufficient to inactivate one or more infectious agents and/or to stimulate healthy cell growth causing a healing effect, and a removable EMR conduction system at least partially insertable into and removable from the lumen of the catheter. The EMR conduction system has at least one optical element providing axial propagation of the therapeutic EMR through an insertable elongate body. The elongate body may have an exterior surface between a coupling end and a distal end tip that has at least one modified portion permitting the radial emission of therapeutic EMR from the elongate body proximate the modified portion. Such modified portion may be gradient along the exterior surface.

URINARY CATHETER IRRIGATION DEVICE AND METHOD OF IRRIGATING A URINARY CATHETER
20170224977 · 2017-08-10 ·

Disclosed are a device and a method for irrigating a urinary catheter connected to a drainage bag. The device is configured to be selectively operated in any one of a drainage state, an irrigation state, and a disposal state without requiring its disconnection from the drainage bag. The device includes a port for receipt of a syringe holding an irrigation fluid. When in the drainage state the device enables fluid from the patient to passively drain into the bag. When in the irrigation state the device isolates the catheter from the bag and enables the irrigation liquid to be introduced from the syringe into the catheter and the patient's bladder to produce a contaminated fluid and also enables the contaminated fluid to be withdrawn back into the syringe. In the disposal state the device isolates the catheter from the drainage bag and enables the contaminated fluid to be introduced into the discharge bag.

Peripheral intravenous catheters having flow diverting features

PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.

Closed suction system

A cleaning catheter insertable into a tracheal ventilation tube and an input module are provided for use with a suction source, the input module coupled to the cleaning catheter and including (i) an inflation module, including an inflation chamber separate from the suction source; (ii) a flow regulator, configured to assume first and second fluid-control states; and (iii) a mechanical user control element, which is configured (a) to mechanically and non-electrically set the fluid-control states, (b) to assume first and second configurations, and (c) to mechanically and non-electrically increase pressure in an interior of an inflation chamber during a transition of the mechanical user control element from the first configuration to the second configuration. The flow regulator, when in the first fluid-control state connects the suction source and an interior of an inflatable element of the cleaning catheter in fluid communication to deflate the inflatable element.

Methods and apparatus to inactivate infectious agents on a catheter residing in a body cavity

Methods and apparatus for the inactivation of infectious agents in, on or around a catheter residing in a patient's body cavity. The method comprises transmitting non-ultraviolet sterilizing electromagnetic radiation (EMR) substantially axially along an optical element in the catheter body. Through delivery of the sterilizing EMR to particular areas of highest infection, the present disclosure is able to inactivate the major sources of infection in catheters.

Catheter sheath devices and methods of operating catheter sheath device

A catheter sheath device may include an elongate member and a moveable member. The elongate member may include a first lumen, and the moveable member may include a second lumen. The moveable member may be physically coupled to a portion of the elongate member to permit relative movement therebetween. A first relative movement between the moveable member and a portion of the elongate member may cause the second lumen to be positioned at a first location that permits delivery of at least a portion of a catheter into the second lumen but not into the first lumen from the second lumen. A second relative movement between the moveable member and the portion of the elongate member may cause the second lumen to be positioned at a second location that permits delivery of the at least the portion of the catheter through both the second lumen and the first lumen.

UV light disinfection and cleaning of narrow tube lumens
11246953 · 2022-02-15 · ·

Systems and methods for cleaning and disinfecting contaminated tube lumens are described herein. One system includes an ultraviolet light source and a sterile fluid reservoir fluidly coupled to a liquid light guide. The system is configured to allow simultaneous access and propagation of ultraviolet light and fluid in a tube having a lumen to be cleaned and disinfected. The light guide can be moved inside the tube and simultaneously emit ultraviolet light through its walls and at its distal end into the interior of the contaminated tube. A flush of sterile fluid from an open end of the liquid light guide removes debris and micro-organism detached from the inner surface during light exposure. The sterile fluid can be a high refractive index ionic solution promoting light propagation.

REUSABLE URINARY CATHETER KITS

Kits are provided for storing, transporting, and sterilizing reusable urinary catheters. A reusable urinary catheter stored within a housing of the kit may be sterilized between uses using a sterilization fluid or sterilizing light. If the reusable urinary catheter is sterilized using a sterilization fluid, the housing may include a manually actuated or electromechanical pump to circulate the sterilization fluid through the housing. The reusable urinary catheter may include a funnel secured to a catheter shaft, with a plurality of lateral openings defined in the funnel, which provide fluid communication between an interior of the funnel and an external surface of the catheter shaft. By allowing fluid communication between the interior of the funnel and the external surface of the catheter shaft, the lateral openings allow for fluid sterilization of both internal and external surfaces of the catheter shaft.
