A urinary drainage system can include an air pressure apparatus with a connector having an elongate connector body. The connector includes a lumen having a larger proximal lumen diameter and a smaller distal lumen diameter. The system includes an air intake adapter having an elongate adapter body, including a proximal end having a proximal opening configured to be coupled to the distal end of the connector. The adapter can include an air intake port in fluid communication with the adapter lumen, the adapter lumen having a larger proximal lumen diameter and a smaller distal lumen diameter.

Implants comprising electrically-responsive hydrogel are described. Systems to provide electricity to induce response in hydrogel-containing implants are described. Methods for utilizing said system and methods for utilizing said hydrogel-containing implants are described.

A temporary low profile intraluminal catheter for infusing agents into, or extracting fluids from, a bodily lumen featuring securement structure, wherein the securement structure allows the catheter to be placed with minimal intrusion into the bodily lumen is disclosed. With such design affording a more efficient, verifiable placement of the catheter with less complication due to infection and biofilm related issues, among other types of complications.

A female urinary catheter system may be provided that utilizes a drainage aperture element having an outer drain edge surrounding an inner drain aperture. The inner drain aperture is coupled to a drainage conduit. The outer drain edge comprises a width dimension larger than that of the drainage conduit. One or more of the outer drain edge, the inner drain aperture, and the drainage conduit may be fabricated from a thermo-responsive polymer. The catheter system may further utilize a catheter conduit coupled to the drainage conduit. The catheter conduit utilizes one or more conduit segments each comprising a first terminal end and a second terminal end. The first terminal end of each conduit segment overlaps the second terminal end of each adjacent conduit segment at respective coupling joints. The catheter system may further utilize an anchor element coupled to the drainage conduit and the catheter conduit.

A urine collection catheter is provided. The catheter includes: a conduit having an open distal end; a drainage tube positioned at least partially within the conduit; and a bladder superior wall support. The drainage tube includes one or more fluid ports or perforations for permitting fluid flow into a drainage lumen defined by the drainage tube. The bladder superior wall support includes a support cap and a plurality of support members extending from a proximal surface of the support cap through the open distal end of the conduit. The support cap is capable of being moved between a retracted position and a deployed position. In the deployed position, the distal end of the drainage tube is spaced apart from the support cap, such that the support cap supports portions of the superior wall of the bladder from occluding the one or more fluid ports or perforations of the drainage tube.

A temporary low profile intraluminal catheter for infusing agents into, or extracting fluids from, a bodily lumen comprising securement means, wherein said securement means allows said catheter to be placed with minimal intrusion into said bodily lumen is disclosed. With such design affording a more efficient, verifiable placement of said catheter with less complication due to infection and biofilm related issues, among other types of complications.

The present invention provides oxygenized nanobubbles and their uses in imaging and cancer treatment when combined with therapeutic drugs and precise ultrasound beam steering.

A method delivers an implantable device through the urethra and into the bladder. A deployment instrument is inserted into the urethra, the implantable device is inserted into the deployment instrument, and a stream of fluid is injected into the deployment instrument. The stream of fluid drives the implantable device from the deployment instrument into the bladder. The deployment instrument is removed from the urethra, leaving the implantable device wholly implanted in the bladder.

Implantable drug delivery devices are provided to have a deployment shape for implantation in the body and a retention shape for retention in the body. The device may have one or more elongated drug reservoirs containing a drug, and the drug reservoir may be formed from a deformable material. In one case, a first filament is attached to the first end of the drug reservoir and second filament is attached to the second end of the drug reservoir, wherein a fastener is positioned about the first and second filaments to permit shortening and prevent lengthening of the filaments with reference to the ends of the drug reservoir, as a means for transforming the device from the implantation shape to the retention shape.

A device for insertion of material into a urethra comprising: a nozzle with a rounded nozzle tip, sized for at least partial insertion into the urethra; and a source of compressed material coupled to the nozzle where a pressure of the compressed material is less than 200 cm H.sub.2O; a control, for control of flow of material from the source through the nozzle; wherein a maximum extent of the device is less than 30 cm.
