Abstract

Embodiments of the disclosed positioning systems can include a catheter assembly having a catheter with an external surface and an outer diameter, and a movable cuff assembly engaged around the circumference of the catheter. An exemplary movable cuff assembly includes a sleeve, a tissue ingrowth cuff affixed to the sleeve, and a clamp affixed to the sleeve, where when the first clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter and wherein when the first clamp is disengaged, the movable cuff assembly is slidably movable over the external surface of the catheter.

Claims

1. A catheter assembly comprising:

a catheter having an external surface having an outer diameter;

a movable cuff assembly engaged around the circumference of the catheter, the movable cuff assembly comprising;

a sleeve that defines a plurality of openings;

a tissue ingrowth cuff woven in the plurality of openings and affixed to the sleeve; and

a first engagable clamp affixed to the sleeve, wherein when the first clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter and wherein when the first clamp is disengaged, the movable cuff assembly is slidably movable over the external surface of the catheter.

2. The catheter assembly of claim 1, wherein the external surface of the catheter is substantially smooth and free of projections.

3. The catheter assembly of claim 1, wherein the sleeve and the catheter have similar pliability.

4. The catheter assembly of claim 1, wherein the first engageable clamp further comprises a first living hinge.

5. The catheter assembly of claim 1, wherein the movable cuff assembly has an inner diameter larger than the outer diameter of the catheter when the first clamp is disengaged and wherein the inner diameter of the movable cuff assembly is smaller than the outer diameter of the catheter when the first clamp is engaged.

6. The catheter assembly of claim 1, further comprising a second engagable clamp affixed to the sleeve, wherein when the second engagable clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter.

7. The catheter assembly of claim 6, wherein the movable cuff assembly has an inner diameter larger than the outer diameter of the catheter when the second clamp is disengaged and wherein the inner diameter of the movable cuff assembly is smaller than the outer diameter of the catheter when the second clamp is engaged.

8. The catheter assembly of claim 6, wherein the second engageable clamp further comprises a second living hinge.

9. A kit comprising:

a catheter including an external surface and having an outer diameter;

a movable cuff assembly engagable around the circumference of the catheter, the movable cuff assembly comprising;

a sleeve that defines a plurality of openings;

a tissue ingrowth cuff woven in the plurality of openings and affixed to the sleeve; and

a first engagable clamp affixed to the sleeve, wherein when the first clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter and wherein when the first clamp is disengaged, the movable cuff assembly is slidably movable over the external surface of the catheter.

10. The kit of claim 9, wherein the external surface of the catheter is substantially smooth and free of projections.

11. The kit of claim 9, wherein the sleeve and that catheter have similar pliability.

12. The kit of claim 9, wherein the movable cuff assembly has an inner diameter larger than the outer diameter of the catheter when the first clamp is disengaged and wherein the inner diameter of the movable cuff assembly is smaller than the outer diameter of the catheter when the first clamp is engaged.

13. The kit of claim 9, further comprising a second engagable clamp affixed to the sleeve, wherein when the second engagable clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter.

14. The kit of claim 13, wherein the movable cuff assembly has an inner diameter larger than the outer diameter of the catheter when the second clamp is disengaged and wherein the inner diameter of the movable cuff assembly is smaller than the outer diameter of the catheter when the second clamp is engaged.

15. A method of uniting an apparatus, the method comprising:

for a particular clinical application for a particular patient, determining a longitudinal location on a catheter to position a tissue ingrowth cuff, wherein the catheter has an external surface having an outer diameter;

moving a movable cuff assembly longitudinally along the catheter, wherein the movable cuff assembly is positioned around the catheter, wherein the movable cuff assembly includes a sleeve that defines a plurality of openings, a tissue ingrowth cuff woven in the plurality of openings and affixed to the sleeve and a first engagable clamp affixed to the sleeve, wherein when the first clamp is engaged, the movable cuff assembly is substantially fixed in position on the external surface of the catheter and wherein when the first clamp is disengaged, the movable cuff assembly is slidably movable over the external surface of the catheter; and

engaging the first clamp thereby longitudinally positioning the movable cuff assembly on the catheter.

16. The method of claim 15, further comprising:

before determining a longitudinal location on the catheter to locate the movable cuff assembly, inserting the catheter into the particular patient.

17. The method of claim 15, wherein the external surface of the catheter is substantially smooth and free of projections.

18. The method of claim 15, wherein the movable cuff assembly has an inner diameter larger than the outer diameter of the catheter when the first clamp is disengaged and wherein the inner diameter of the movable cuff assembly is smaller than the outer diameter of the catheter when the first clamp is engaged.
