Selectively positionable catheter cuff
View Patent ↗Devices and methods for securing a catheter with the body of a patient are generally disclosed. In particular, selectively positionable cuffs and methods for attaching selectively positionable cuffs to long-term tunneled catheters are disclosed. In one embodiment, a slidable, selectively-positionable cuff comprises an adhesive on a foldable tab. In another embodiment, a slidable, selectively positionable cuff comprises an activatable adhesive that is convertible from a nonadherent state to an adherent state beneath the skin of the patient. Additionally, the present disclosure teaches a wrappable sheet comprising a harvested extracellular matrix with an adhesive positioned on a side thereon and arranged to be adhered to the surface of a catheter so as to form a cuff. Methods of securing and/or positioning a cuff on a catheter, kits, and other embodiments are disclosed.
1. A cuff, comprising:
a cuff body arranged to be slidable along a portion of a catheter shaft when the cuff body is positioned around the catheter shaft of a catheter having a distal tip;
a pivotable portion pivotably associated with said cuff body and arranged to pivot from a first position remote from the catheter shaft to a second position proximate to the catheter shaft when the cuff body is positioned around the catheter shaft; and
an adhesive positioned on a first side of said pivotable portion and arranged to adhere said pivotable portion to the catheter shaft when said pivotable portion is in said second position;
wherein the pivotable portion has a second side opposite said first side;
wherein when said cuff body is positioned around the catheter shaft in said first position, said second side of the pivotable portion faces said catheter shaft and said first side faces away from said catheter shaft; and
wherein when said cuff body is positioned around the catheter shaft in the said second position, said second side of the pivotable portion faces away from said catheter shaft and said first side faces said catheter shaft.
2. The cuff of claim 1 , wherein:
said pivotable portion comprises a foldable tab.
3. The cuff of claim 1 , wherein:
said cuff body comprises harvested extracellular matrix.
4. The cuff of claim 1 , wherein:
said adhesive comprises an activatable adhesive.
5. A cuff, comprising:
a wrappable sheet having a first side and a second side, comprising a harvested extracellular matrix, and arranged to be wrapped around a portion of a catheter shaft of a catheter having a distal tip; and
said first side comprising an adhesive;
wherein said first side faces the catheter shaft when said wrappable sheet is wrapped around a portion of a catheter shaft; and
wherein said wrappable sheet defines a plurality of overlapping layers of harvested extracellular matrix material when wrapped around the catheter shaft.
6. The cuff of claim 5 , wherein:
said adhesive comprises an activatable adhesive.
7. The cuff of claim 5 , further comprising:
a layer coupling member positioned on said second side and arranged to couple adjacent layers of said wrappable sheet.
8. The cuff of claim 7 , further comprising:
a layer coupling member positioned on said first side and arranged to couple to said layer coupling member positioned on said second side.
9. The cuff of claim 7 , wherein:
said layer coupling member comprises an adhesive.
10. The cuff of claim 9 , wherein:
said layer coupling member comprises an activatable adhesive.
11. A kit, comprising:
a catheter having a distal tip;
a cuff selectively positionable around a portion of said catheter and comprising an activatable adhesive that converts from a nonadherent state to an adherent state when activated while beneath skin of a patient;
wherein when said cuff is positioned around said catheter, said cuff is slidable along a length of said catheter from a first position to a second position when said activatable adhesive is in said nonadherent state and said activatable adhesive adheres said cuff to said catheter to resist movement of the cuff along a length of said catheter when said activatable adhesive is in said adherent state; and
wherein said activatable adhesive is activated by interaction with light having a wavelength sufficient to pass through the skin of the patient.
12. The kit of claim 11 , wherein:
the cuff comprises harvested extracellular matrix.
13. The kit of claim 11 , wherein
said catheter and said cuff are sterilely sealed within a package.
14. A method of adhering a cuff on a catheter, comprising:
advancing a distal tip of the catheter through the body of a patient to a target site beneath skin of the patient;
selectively positioning a portion of a selectively positionable cuff having an activatable adhesive thereon on a portion of the catheter arranged for positioning beneath the skin when the distal tip is at the target site;
positioning a portion of the cuff beneath the skin of the patient prior to activating the activatable adhesive; and
activating the activatable adhesive so as to adhere the cuff to the catheter and resist movement of the cuff along a length of the catheter.
15. The method of claim 14 , further comprising:
tunneling a portion of a catheter beneath the skin of a patient.
16. The method of claim 14 , wherein:
the cuff is selectively positionable around a portion of the catheter and comprises an activatable adhesive that is convertible from a nonadherent state to an adherent state;
wherein in the nonadherent state the cuff is slidable along a length of the catheter from a first position to a second position; and
wherein in the adherent state the activatable adhesive adheres the cuff to the catheter to resist movement of the cuff along a length of the catheter.
17. The method of claim 14 , wherein the cuff comprises:
a cuff body arranged to be slidable along a portion of a catheter shaft;
a pivotable portion pivotably associated with the cuff body and arranged to pivot from a first position remote from the catheter shaft to a second position proximate to the catheter shaft; and
an adhesive positioned on the pivotable portion and arranged to adhere the pivotable portion to the catheter shaft when the pivotable portion is in the second position.
18. The method of claim 14 , wherein the cuff comprises:
a wrappable sheet having a first side and a second side, comprising a harvested extracellular matrix, and arranged to be wrapped around a portion of a catheter shaft; and
the first side comprising an adhesive;
wherein the first side faces the catheter shaft when the wrappable sheet is wrapped around a portion of the catheter shaft.
19. The method of claim 14 , wherein:
activating the activatable adhesive comprises curing the activatable adhesive.
20. The method of claim 14 , wherein:
positioning a portion of a cuff on a portion of the catheter comprises sliding a portion of the cuff along a length of the catheter.
21. The method of claim 14 , wherein:
positioning a portion of a cuff on a portion of the catheter comprises wrapping a portion of the cuff around the catheter.
22. The method of claim 14 , wherein:
the cuff comprises a harvested extracellular matrix.
23. The method of claim 14 , wherein:
the activatable adhesive is activatable by interaction with light.
24. The method of claim 23 , wherein:
the activatable adhesive is activatable by interaction with light that has passed through the skin of the patient.
