A catheterization package including a catheterization tray and contents for a catheterization procedure. The catheterization tray can include a structural configuration for maintaining a sterile field about a patient throughout the catheterization procedure, the sterile field including at least a portion of the tray. The structural configuration of the tray can provide a sterile side of the tray designated for a first person performing sterile steps of the catheterization procedure in the sterile field. The structural configuration of the tray can also provide a non-sterile side of the tray designated for either the first person or a second person performing non-sterile steps of the catheterization procedure outside the sterile field. The contents for the catheterization procedure can include a perineal care kit, two or more pairs of gloves, and a drainage system including a catheter.

Ureteral and bladder catheters and methods of inducing negative pressure to increase renal perfusion

A ureteral catheter includes a drainage lumen including a proximal portion configured to be positioned in at least a portion of a patient's urethra and/or bladder and a distal portion configured to be positioned in a patient's kidney, renal pelvis, and/or in the ureter adjacent to the renal pelvis, the distal portion including a retention portion for maintaining positioning of the distal portion of the drainage lumen, the retention portion including two or more openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen, wherein a number of the openings nearer to a distal end of the retention portion is greater than a number of the opening(s) nearer to a proximal end of the retention portion.

INTERMITTENT CATHETER
20240042168 · 2024-02-08 ·

Described is a catheter arrangement in which a sealed container of wetting agent is provided in a housing cap. The sealed container is pierced with a piercing member such that the wetting agent is directed towards the catheter. The wetting agent may bypass a handling surface of the catheter whilst being directed to the catheter tube.

METHOD AND APPARATUS FOR TREATING GENITOURINARY PROBLEMS

Apparatus and methods for treatment of bleeding and/or microbial infection of the genitourinary tract including a catheter and an insertable and removable medicament-delivery sheath for introducing a hemostatic and/or anti-microbial substance or the like. Some embodiments further include a light-delivery sheath and/or light-delivery-and-imaging sheath having a light-propagation channel, and a source of anti-microbial and/or imaging light in one or more wavelength bands, for example UVC light and/or light in the visible violet, blue or green wavelength ranges. Some embodiments include a display for captured images, and/or a motorized sheath-movement device configured to move one or more light-output ports. Some embodiments further include a light-propagation channel built into the catheter itself (such as one or more optical fibers) for the administration of anti-microbial ultraviolet light (and/or other wavelengths of light) light along the catheter and/or at the distal end of the catheter to treat and/or prevent microbial (bacterial and/or fungal) infections.

CATHETER PLACEMENT DEVICE FOR URETHRAL APPLICATIONS
20240042178 · 2024-02-08 ·

A portable hand-held medical device includes a body having a gun-type formation that includes a barrel. A guide wire device is housed in the body and is configured to advance and retract through the barrel. The guide wire device carries a bundled arrangement including a video system, an illumination system to support the video system, a fluid irrigation line, and a guide wire mechanism. The bundled arrangement is packaged as a unit in an insertion tube. The tip section of the insertion tube incorporates a camera, a light source, and a fluid irrigation port. A catheter is disposed at the end of the barrel, so that during operation the guide wire device passes through the catheter lumen. The combination guide wire device and catheter enter the urinary tract and perform a bladder evacuation process.

Multi-port syringe system and method for use with a urinary catheter
11890405 · 2024-02-06 ·

A multi-port medical syringe comprises a port body, a syringe barrel, and a plunger. The port body comprises a cylindrical cavity with at least three ports. The three port are configured to connect the cylindrical cavity of the port body with three medical devices: a first port configured for attachment to a medical device such as an input fluid source; a second port configured for fluid transmission through a urinary catheter to a bladder of a human or animal; and a third port configured for attachment to a medical device such as a drainage fluid storage vessel. The syringe barrel comprises a cylindrical tube, at least a portion of which fits snugly inside the cylindrical cavity of the port body. The syringe barrel further comprises a syringe barrel port located proximate to, or in, an otherwise closed end of the syringe barrel. Selection of the first, second or third port comprises a rotation of the syringe barrel relative to the port body, about the barrel cylindrical tube central axis, to align the syringe barrel port with the selected port body port. The plunger fits inside the cylindrical tube of the syringe barrel. The plunger can be manually grasped and moved longitudinally along the barrel cylindrical tube central axis to transmit fluid through the port of the port body that was selected by rotating the syringe barrel inside the port body.

Ductus sede-entry and prosthetic disorder response systems
20190374213 · 2019-12-12 ·

Described are means for the direct and continuous connection of a catheter to the lumen of any tubular anatomical structure, or ductus, without medically significant leakage. A port implanted at the body surface with piping to a periductal collar allows drug or radionuclide delivery that bypasses the upstream lumen. The port allows injection, infusion, aspiration, or attachment of an automatic ambulatory pump. A superparamagnetic nanoparticle carrier-bound drug, for example, can be introduced into the lumen to pass downstream until the particles, with or without the drug still bound, are drawn into the lumen wall by a magnetized jacket surrounding the ductus. Such constitutes a method of drug targeting whereby a segment of a vessel or the territory supplied by a branch of that segment can be circumscribed for exposure to the drug. A jacket with side-entry connector positioned in surrounding relation to a lesion requiring treatment can itself be magnetized.

Systems and Methods for Inducing Negative Pressure in a Portion of a Urinary Tract of a Patient

Ureteral or bladder catheters are provided, including (a) a proximal portion; and (b) a distal portion, the distal portion including a retention portion that includes one or more protected drainage holes, ports or perforations and is configured to establish an outer periphery or protective surface area that inhibits mucosal tissue from occluding the one or more protected drainage holes, ports or perforations upon application of negative pressure through the catheter. Systems, kits and methods for inducing negative pressure to increase renal function also are provided.
