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 urinary catheter for bladder control management, the urinary catheter comprising:
a body having a proximal portion, a distal portion, and an elongated midsection between the proximal portion and the distal portion, wherein the elongated midsection comprises a lumen extending from the proximal portion to the distal portion, and wherein the lumen is configured to allow fluid to flow therethrough, wherein the lumen is in fluid communication with an opening in the distal portion body;
a valve disposed in the distal portion and in fluid communication with the lumen and in fluid communication with the opening, wherein the valve is configured to allow fluid to flow from the elongated midsection to the opening, wherein the valve comprises a distal insert comprising one or more inlets, a spring coupled to the distal insert, a ball, and a proximal insert comprising a ring shape with an inner radius smaller than a radius of the ball, wherein the ball is disposed between the spring and the proximal insert;
an anchor disposed in the proximal portion, the anchor being configured to transition between an expanded configuration to retain the urinary catheter within a bladder of a patient and a collapsed configuration to allow the urinary catheter to be received within and passed through a bladder neck and urethra; and
a wireless actuation mechanism configured to activate the valve and control fluid flow through the valve and increase or decrease the flow of fluid based upon user input,
wherein the urinary catheter is configured to be implanted with the bladder of the patient.
2 . The urinary catheter of claim 1 , wherein the distal portion comprises an attachment mechanism configured to engage a corresponding attachment mechanism on an insertion device for positioning the urinary catheter.
3 . The urinary catheter of claim 2 , wherein the urinary catheter is configured such that wherein upon engagement between the corresponding attachment mechanisms, fluid can flow from the lumen into the insertion device.
4 . The urinary catheter of claim 3 , wherein the urinary catheter is configured such that wherein upon disengagement of the corresponding attachment mechanisms from one another, fluid cannot flow into the insertion device.
5 . The urinary catheter of claim 1 , wherein the anchor comprises a first portion comprising a wall surrounding the lumen and a second portion comprising a first wall portion and a second wall portion, wherein the first portion is distal to the second portion, wherein the first wall portion and the second wall portion are attached to the first portion and to a tip, wherein the first wall portion and the second wall portion extend outwardly in the expanded configuration greater than a diameter of the wall in the first portion.
6 . The urinary catheter of claim 5 , wherein the anchor is configured to change from the expanded configuration to the collapsed configuration when a first force is applied on the tip, when a direction of the first force is applied in a direction corresponding to distal to proximal.
7 . The urinary catheter of claim 1 , wherein the urinary catheter is configured to allow a pushwire to be inserted from the opening to the tip.
8 . The urinary catheter of claim 1 that is configured with variable tubing diameters to prevent migration of the device.
9 . The urinary catheter of claim 1 , wherein the insertion device comprises a pushwire with a longitudinal length greater than the combined longitudinal lengths of the urinary catheter and the insertion device, and wherein the urinary catheter is configured to allow the pushwire to travel from the opening to a tip on the proximal end of the urinary catheter to exert a force on the tip such that the anchor changes from the expanded configuration to the collapsed configuration.
10 . The urinary catheter of claim 1 , wherein the valve comprises a cylindrical magnetic ball valve.
11 . The urinary catheter of claim 1 , wherein the spring is configured to constantly exert tension during opening and closing of the cylindrical magnetic ball valve.
12 . The urinary catheter of claim 1 , wherein the valve is configured to be in an open position when a magnetic force is exerted on the valve, and wherein the valve is configured to be in a closed position when no magnetic force is exerted on the valve.
13 . The urinary catheter of claim 1 , further comprising a mating ledge disposed near the opening, wherein the mating ledge comprises a smaller inner diameter than the opening.
14 . The urinary catheter of claim 1 , further comprising a mating ledge disposed near the opening, wherein the mating ledge comprises a conductive material.
15 . The urinary catheter of claim 1 , further comprising an insertion device configured to insert the body into the patient, wherein the insertion device comprises an attachment mechanism configured to mate with a corresponding attachment mechanism that is inside of the lumen of the body at the distal portion.
16 . The urinary catheter of claim 15 , wherein the corresponding attachment mechanism comprises a semi-rigid lip.
17 . The urinary catheter of claim 15 , wherein the attachment mechanism comprises a first configuration and a second configuration and expands from the first configuration to the second configuration to mate with the corresponding attachment mechanism.
18 . The urinary catheter of claim 15 , wherein the corresponding attachment mechanism comprises a ledge.
19 . The urinary catheter of claim 15 , further comprising a mating ledge disposed near the opening, wherein the mating ledge comprises a conductive material, and wherein the mating ledge is configured to complete a circuit when the attachment mechanism is mated to the mating ledge.
20 . The urinary catheter of claim 10 , wherein the magnetic ball valve is configured such that when a magnetic force is exerted on the magnetic ball valve, the valve is in an open position and allows fluid to pass through the valve, and
wherein the magnetic ball valve is configured such that when a magnetic force is not exerted on the magnetic ball valve, the valve is in a closed position and does not allow fluid to pass through the valve.
