Extended-use valved urinary catheter
The disclosure relates generally to an extended use systems and devices for management of bladder function for people with urinary dysfunction. The system includes a catheter and a valve that can control fluid flow. The catheter can be placed inside the bladder using devices that facilitate insertion and extraction. The placement of the catheter can be done by a trained individual such as a patient, as well as a clinician, a nurse, or a caretaker. Once placed inside the bladder, the catheter can be fully-internal, meaning no portion of the catheter is visible from outside of the patient's body.
1. A bladder management system comprising:
a fully-internal catheter configured to be placed inside of and retained in a bladder of a patient's body and invisible to human eyes from outside of the body once inside the bladder, the fully-internal catheter comprising (a) a lumen extending through the catheter, wherein the lumen is configured to transport fluid, a proximal end and a distal end, wherein the distal end comprises an opening that is in communication with the lumen, (b) a retaining portion having a first configuration in which it can pass through the urethra, and a second, expanded configuration in which it is configured to be retained in the bladder and cannot pass through the urethra, the retaining portion juxtaposed the proximal end, and (c) an electromagnetic valve that has a first, open position and a second, closed position, and (d) a mating ledge juxtaposed the distal end and being between the electromagnetic valve and the distal end; and
an insertion device comprising a mating guide configured to mate with the mating ledge, wherein the mating guide has a first configuration in which it does not mate with the mating ledge, and a second, expanded configuration in which it does mate with the mating ledge.
2. The system of claim 1 , wherein the mating guide further comprises a tapered insert.
3. The system of claim 1 , wherein the mating guide comprises a balloon.
4. The system of claim 1 , wherein the mating guide comprises a balloon catheter and a Y-Connector configured for inflation of the balloon catheter to the second, expanded configuration and deflation of the balloon catheter to the first configuration.
5. The system of claim 1 that further comprises an extraction device having a mating guide with a first configuration in which it does not mate with the mating ledge, and a second, expanded configuration in which it does mate with the mating ledge.
6. The system of claim 1 , wherein the insertion device mating guide can be selectively locked in the second, expanded configuration to facilitate insertion of the catheter.
7. The system of claim 1 , wherein the mating guide comprises a Y-Connector attached to a balloon catheter.
8. The system of claim 7 that further includes a magnet configured to open and close the electromagnetic valve.
