Abstract

The various implementations described herein include a percutaneous port for promoting tissue in-growth around the percutaneous port. In one aspect, the percutaneous port includes a tubular structure having an outer surface, and a coil having an outer surface and comprised of a plurality of loops. Furthermore, at least a portion of the outer surface of the coil is joined to the outer surface of the tubular structure.

Claims

1. A percutaneous port for promoting tissue in-growth around the percutaneous port, comprising:

a tubular structure having an outer surface; and

a coil having an outer surface and comprised of a plurality of loops,

wherein at least a portion of the outer surface of the coil is joined to the outer surface of the tubular structure.

2. The percutaneous port of claim 1, wherein a cross section of the tubular structure is circular, square, rectangular, or polygonal.

3. The percutaneous port of claim 1, wherein the coil forms a spiral around the tubular structure.

4. The percutaneous port of claim 3, further comprising an additional coil having an outer surface and comprised of a plurality of loops, wherein the additional coil also forms a spiral around the tubular structure, wherein the plurality of loops of the coil have a substantially larger diameter than the plurality of loops of the additional coil.

5. The percutaneous port of claim 4, wherein the spiral formed by the additional coil is interleaved with the spiral formed by the coil.

6. The percutaneous port of claim 1, wherein after joining, at least some of the plurality of loops are oriented so as to form an angle with the outer surface of the tubular structure.

7. The percutaneous port of claim 1, wherein the at least a portion of the outer surface of the coil is brazed to the outer surface of the tubular structure.

8. The percutaneous port of claim 1, wherein:

the outer surface of the tubular structure comprises a plated material; and

the coil comprises a coil material, wherein the plated material and the coil material are chemically reactive with one another.

9. The percutaneous port of claim 1, wherein the coil comprises a material selected from the group consisting of titanium and its alloys, nitinol, tungsten and its alloys, molybdenum and its alloys, niobium and its alloys, cobalt-chromium based alloys, noble metals and their alloys, and medical grade stainless steel.

10. The percutaneous port of claim 1, wherein the tubular structure is made from titanium.

11. The percutaneous port of claim 1, wherein the outer surface of the tubular structure is made from nickel.

12. A percutaneous port for promoting tissue in-growth around the percutaneous port, comprising:

a plate having opposing substantially flat first and second surfaces, wherein the plate defines a hole there through;

a coil having an outer surface and comprised of a plurality of loops,

wherein at least a portion of the outer surface of the coil is joined to the first surface of the plate around the hole.

13. The percutaneous port of claim 12, wherein the plate is circular, square, rectangular, or polygonal shaped.

14. The percutaneous port of claim 12, wherein the coil forms a spiral around the hole of the plate.

15. The percutaneous port of claim 14, further comprising an additional coil having an outer surface and comprised of a plurality of loops, wherein the additional coil forms an additional spiral around the hole of the plate,

the spiral has a first spiral diameter, and the additional spiral has a second spiral diameter distinct from the first spiral diameter, and

the plurality of loops of the coil have a first loop diameter, and the plurality of loops of the additional coil has a second loop diameter distinct from the first loop diameter.

16. The percutaneous port of claim 15, wherein the spiral formed by the coil is interleaved with the additional spiral formed by the additional coil.

17. The percutaneous port of claim 12, wherein after joining, at least some of the plurality of loops are oriented so as to form an angle with the first surface of the plate.

18. The percutaneous port of claim 12, wherein the at least a portion of the outer surface of the coil is brazed to the first surface of the plate.

19. The percutaneous port of claim 18, wherein:

the first surface of the plate comprises a plated material; and

the coil comprises a coil material, wherein the plated material and the coil material are chemically reactive with one another.

20. The percutaneous port of claim 12, wherein the coil comprises a material selected from the group consisting of:

titanium and its alloys, nitinol, tungsten and its alloys, molybdenum and its alloys, niobium and its alloys, cobalt-chromium based alloys, noble metals and their alloys, and medical grade stainless steel.

21. The percutaneous port of claim 12, wherein the plate is made from titanium.

22. The percutaneous port of claim 12, wherein the first surface of the plate is made from nickel.
