Abstract

The invention relates to a design for securing tubes, catheters, drains, or other tubular medical devices within the body of a mammal, for example a human, and methods of securing same. The invention includes a first tubular body and at least one second tubular body. The first tubular body includes an outer surface, an inner surface defining a lumen extending longitudinally at least partially through a length of the tubular body, a wall at least partially defined by the outer surface and the inner surface, and a longitudinal axis. The at least one second tubular body includes an outer surface, an inner surface defining a lumen extending longitudinally through the second tubular body, and a wall at least partially defined by the outer surface and the inner surface. The second tubular body is disposed through the wall of the first tubular body transversely to the longitudinal axis.

Claims

1. A catheter comprising:

(a) a first tubular body comprising;

an outer surface;

an inner surface defining a lumen extending longitudinally at least partially through a length of the tubular body;

a wall at least partially defined by the outer surface and the inner surface; and

a longitudinal axis;

(b) at least one second tubular body comprising;

an outer surface;

an inner surface defining a lumen extending longitudinally through the second tubular body; and

a wall at least partially defined by the outer surface and the inner surface, wherein the second tubular body is disposed through the wall of the first tubular body transversely to the longitudinal axis and substantially flush with the outer surface of the first tubular body; and

(c) a fastening mechanism for securing the catheter to a subject comprising;

a ring dimensioned to pass through the lumen of a said second tubular body, the ring having opposed free ends and constructed and arranged so that the ring can assume one of an open configuration and a closed configuration; and

a locking mechanism to reversibly secure the ring in the closed configuration and including mating first and second locking members that are respectively supported at the opposed free ends of the ring wherein the fastening mechanism further comprises a strap member for coupling the ring to the subject.

2. The catheter of claim 1, wherein an outer cross-sectional dimension of the second tubular body is less than a thickness of the wall of the first tubular body.

3. The catheter of claim 1, further comprising a plurality of second tubular bodies disposed through the wall of the first tubular body.

4. The catheter of claim 3, wherein the plurality of second tubular bodies are evenly spaced along an overall length of the first tubular body.

5. The catheter of claim 3, wherein a portion of the plurality of second tubular bodies are more closely spaced together at an end of the first tubular body than a remaining portion of the plurality of second tubular bodies.

6. The catheter of claim 3, wherein a first portion of the plurality of second tubular bodies are radially disposed about a central longitudinal axis of the first tubular body from a second portion of the plurality of the second tubular bodies.

7. The catheter of claim 6, wherein the first portion of the second tubular bodies is radially disposed about 180 degrees from the second portion of the second tubular bodies.

8. The catheter of claim 1, wherein a cross-sectional dimension of the inner surface of the second tubular body comprises a diameter of about 0.1 mm to about 5.0 mm.

9. The catheter of claim 1, wherein the outer surface of the first tubular body and the inner surface of the first tubular body are eccentric.

10. The catheter of claim 1, wherein the first tubular body comprises a material selected from the group consisting of polyurethane, silicones, polyethylenes, nylons, polyesters and polyester elastomers.

11. The catheter of claim 1, wherein the second tubular body comprises a material selected from the group consisting of stainless steel, titanium, polyurethane, silicones, polyethylenes, nylons, polyesters and polyester elastomers.

12. The catheter of claim 1, wherein the catheter comprises a cross-sectional shape selected from the group consisting of circular, elliptical, polygonal, and combinations thereof.

13. The catheter of claim 1, wherein the cross-sectional shape of the inner surface of the second tubular body is at least one of circular, elliptical, polygonal, and combinations thereof.

14. The catheter of claim 1 further comprising a radio-opaque material disposed therein.

15. The catheter of claim 1, wherein the first tubular body further comprises a second inner surface defining a second lumen extending longitudinally at least partially through the length of the tubular body.

16. The catheter of claim 1 further comprising a series of markings disposed on the outer surface of the first tubular body.

17. A catheter comprising:

(a) a tubular body comprising;

an outer surface;

an inner surface defining a lumen extending longitudinally at least partially through a length of the tubular body;

a wall at least partially defined by the outer surface and the inner surface;

a longitudinal axis; and

at least one opening extending through the wall substantially transversely to the longitudinal axis, wherein the at least one opening is in fluidic isolation from the lumen; and

(b) a fastening mechanism comprising;

a ring dimensioned to pass through the opening, the ring having opposed free ends and constructed and arranged so that the ring can assume one of an open configuration and a closed configuration, and

a locking mechanism to reversibly secure the ring in the closed configuration and including mating first and second locking members that are respectively supported at the opposed free ends of the ring wherein the fastening mechanism further comprises a strap member for coupling the ring to a mammalian body.

18. The catheter of claim 17, wherein the strap member comprises:

a first layer of material adapted for attachment to a portion of the mammalian body; and

a second layer of material adapted to secure at least a portion of the ring to the strap member.

19. The catheter of claim 17, wherein the strap member is adapted to provide a floating connection of the catheter to the mammalian body.

20. The catheter of claim 17, wherein the locking mechanism comprises at least one of a box clasp, a toggle clasp, a hook and eye clasp, a friction clasp, and a magnetic clasp.
