Flushable catheters
A flushable catheter assembly includes a catheter shaft having proximal and distal end portions. The catheter may include a funnel assembly associated with the distal end portion of the catheter shaft and/or an introducer cap assembly associated with the proximal end portion of the catheter shaft. A groove is defined along at least a portion of an outer perimeter of the funnel assembly or introducer cap assembly, with the groove being configured to receive at least a portion of the catheter shaft for wrapping the catheter shaft around the outer perimeter when disposing of the catheter. Instead of (or in addition to) a groove, one or more channels may pass through the funnel assembly to receive a portion of the catheter shaft for securing the catheter shaft to the funnel assembly for disposal. The catheter assembly and/or its individual components may be formed of a water disintegrable material.
1. A catheter assembly comprising:
a catheter shaft having proximal and distal end portions; and
a funnel assembly fixedly secured to the distal end portion of the catheter shaft, wherein
a drainage portion is defined through the funnel assembly and the funnel assembly includes
a groove along at least a portion of an outer perimeter of the funnel assembly and/or
a shaft channel defined through the funnel assembly, with the groove and/or the shaft channel being configured to receive at least a portion of the catheter shaft for securing said at least a portion of the catheter shaft to the funnel assembly for disposal,
the drainage portion is positioned between a pair of lateral portions,
each lateral portion includes a front face and a rear face, and
the groove is defined between the front and rear faces.
2. The catheter assembly of claim 1 , wherein the funnel assembly defines an opening, the opening being configured to receive at least one digit of a user or a portion of the catheter shaft.
3. The catheter assembly of claim 1 , wherein the funnel assembly defines at least one hole configured to trap water and improve movement of the catheter assembly through a drainage pipe.
4. The catheter assembly of claim 1 , wherein the catheter shaft and/or the funnel assembly is at least partially comprised of a water disintegrable material.
5. The catheter assembly of claim 1 , wherein the funnel assembly is at least partially comprised of an activation agent material configured to aid in the breakdown of the catheter shaft and/or the funnel assembly in water.
6. The catheter assembly of claim 1 , wherein at least a portion of one of the catheter shaft and the funnel assembly is formed of a material including sodium bicarbonate and at least a portion of the other one of the catheter shaft and the funnel assembly is formed of a material including acetic acid.
7. The catheter assembly of claim 1 , wherein a width of the groove is at least as great as a diameter of the catheter shaft.
8. The catheter assembly of claim 1 , wherein a width of the groove is less than a diameter of the catheter shaft.
9. The catheter assembly of claim 1 , wherein a depth of the groove is at least as great as a diameter of the catheter shaft.
10. The catheter assembly of claim 1 , wherein a depth of the groove is less than a diameter of the catheter shaft.
11. The catheter assembly of claim 1 , wherein the groove has a varying depth.
12. A catheter assembly comprising:
a catheter shaft having proximal and distal end portions; and
a funnel assembly fixedly secured to the distal end portion of the catheter shaft, wherein
a drainage portion is defined through the funnel assembly and the funnel assembly includes
a groove along at least a portion of an outer perimeter of the funnel assembly and/or
a shaft channel defined through the funnel assembly, with the groove and/or the shaft channel being configured to receive at least a portion of the catheter shaft for securing said at least a portion of the catheter shaft to the funnel assembly for disposal, and
said shaft channel extends between a proximal shaft channel opening associated with a proximal end of the funnel assembly and a distal shaft channel opening associated with a distal end of the funnel assembly.
13. The catheter assembly of claim 12 , further comprising a second shaft channel defined through the funnel assembly and extending between a proximal second shaft channel opening associated with the proximal end of the funnel assembly and a distal second shaft channel opening associated with the distal end of the funnel assembly.
14. The catheter assembly of claim 12 , wherein the catheter shaft and/or the funnel assembly is at least partially comprised of a water disintegrable material.
15. The catheter assembly of claim 12 , wherein the funnel assembly is at least partially comprised of an activation agent material configured to aid in the breakdown of the catheter shaft and/or the funnel assembly in water.
16. The catheter assembly of claim 12 , wherein at least a portion of one of the catheter shaft and the funnel assembly is formed of a material including sodium bicarbonate and at least a portion of the other one of the catheter shaft and the funnel assembly is formed of a material including acetic acid.
17. A catheter assembly comprising:
a catheter shaft having proximal and distal end portions; and
a funnel assembly fixedly secured to the distal end portion of the catheter shaft, wherein
a drainage portion is defined through the funnel assembly and the funnel assembly includes
a groove along at least a portion of an outer perimeter of the funnel assembly and/or
a shaft channel defined through the funnel assembly, with the groove and/or the shaft channel being configured to receive at least a portion of the catheter shaft for securing said at least a portion of the catheter shaft to the funnel assembly for disposal, and
the shaft channel extends between first and second proximal shaft channel openings associated with a proximal end of the funnel assembly.
18. The catheter assembly of claim 17 , wherein the catheter shaft and/or the funnel assembly is at least partially comprised of a water disintegrable material.
19. The catheter assembly of claim 17 , wherein the funnel assembly is at least partially comprised of an activation agent material configured to aid in the breakdown of the catheter shaft and/or the funnel assembly in water.
20. The catheter assembly of claim 17 , wherein at least a portion of one of the catheter shaft and the funnel assembly is formed of a material including sodium bicarbonate and at least a portion of the other one of the catheter shaft and the funnel assembly is formed of a material including acetic acid.
