Extended-use catheters
Described is a catheter for being retained inside the body for extended periods, and a catheter mating device that can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter mating device has a stem with an apparatus at its distal end. The apparatus is moveable between a first position and a second position. When in its first position, the distal end is configured to fit in the proximal end of the catheter. When in its second position, the distal end engages the proximal end of the catheter and connects the catheter mating device to the catheter.
1. A urinary catheter comprising:
(a) a tube, the tube having (i) a wall with an outer surface, the outer surface having a first cross-sectional area, (ii) a lumen, (iii) a distal end with one or more openings in communication with the lumen, and (iv) a proximal end with an opening in communication with the lumen,
(b) a valve that is operated to be in (i) a closed configuration, wherein fluid from a patient's bladder into which the distal end is inserted does not flow out of the proximal end, or (ii) an open configuration, wherein fluid from the patient's bladder into which the distal end is inserted does flow out of the proximal end; and
(c) a compressible solid retainer portion between the distal end and the proximal end, the solid retainer portion (i) having a maximum cross-sectional area at least twice as great as the first cross-sectional area, (ii) being configured to be compressed to have a maximum diameter of 0.3 mm to 8.0 mm when moved through a penile urethra of a patient and to have a maximum diameter of 4.0 mm to 15 mm when positioned in a bulbar urethra of the patient, and (iii) being configured to anchor the distal end in the bladder when the compressible solid retainer portion is positioned inside of the bulbar urethra.
2. The catheter of claim 1 that has a length of 173 mm to 223 mm.
3. The catheter of claim 1 , wherein the solid retainer portion has a first end and a second end, and a first tapered portion at the first end and a second tapered portion at the second end.
4. The catheter of claim 3 , wherein the first tapered portion extends from the outer diameter on the tube to the maximum diameter of the solid retainer portion, and the second tapered portion extends from the outer diameter on the tube to the maximum diameter of the solid retainer portion.
5. The catheter of claim 1 , wherein one or more sensors are positioned at one or more of: the distal end of the catheter, completely inside the lumen of the catheter, partially inside a second lumen of the catheter, and on the solid retainer portion.
6. The catheter of claim 1 , wherein the solid retainer portion has a hardness of an amount from: 1 to 40 Shore A.
7. The catheter of claim 1 , wherein the solid retainer portion is comprised of silicone.
8. The catheter of claim 1 , wherein the solid retainer portion has a maximum cross-sectional area that is 2-3 times greater than the first cross-sectional area.
9. The catheter of claim 1 , wherein the solid retainer portion has a maximum cross-sectional area that is 2-4 times larger than the first cross-sectional area.
10. The catheter of claim 1 that further includes one or more sensors.
11. The catheter of claim 10 , wherein the one or more sensors are configured to collect data of a patient, the data comprising one or more of: fluid pressure inside of a bladder, fluid volume inside of the bladder, temperature inside of the bladder, acidity of urine, bacteria level and type in urine, chemical composition of urine, motion of the patient, location of the patient, and fluid flow when emptying the bladder.
12. The catheter of claim 10 , wherein the one or more sensors are positioned in a bladder when the catheter is positioned in a lower urinary tract of a human male.
13. The catheter of claim 10 that further includes one or more antennas, wherein each of the one or more antennas is configured to receive a communication from the one or more sensors and transmit the communication.
14. The catheter of claim 13 that further includes a second lumen that includes one or more of: the one or more sensors, and the one or more antennas.
15. The catheter of claim 14 , wherein the second lumen has a length and includes one antenna that is at least half the length of the lumen.
16. The catheter of claim 14 , wherein the second lumen has a length and includes one antenna that extends at least 90% of the length.
17. The catheter of claim 13 , wherein the one or more antennas are in electrical contact with the one or more sensors.
18. The catheter of claim 17 , wherein the one or more antennas are physically connected to the one or more sensors.
19. The catheter of claim 18 that has a plurality of sensors.
20. The catheter of claim 13 that has a plurality of antennas.
21. The catheter of claim 1 , wherein the retainer portion has a total length of 3 cm to 7 cm.
22. The catheter of claim 1 , wherein the retainer portion has a maximum cross-sectional area of 4mm2 to 25mm2.
23. The catheter of claim 1 , wherein the solid retainer portion has a top surface having a circular cross-sectional shape and a diameter of 6 mm to 20 mm.
