Abstract

An elongate catheter having one or more lumens therein and at least one lumen in flow communication with a hub member including one or more loop members extending laterally from a tubular member thereof such that a securement area is formed by the opening between the body of the tubular member and the loop member which is significantly larger than currently available catheters. The loop members are formed to provide a soft and flexible area for securing the catheter to the body of the patient wherein the securement area is spaced apart from the body of the hub member and the loop members may be easily removed to allow the catheter to be removed from the body of the patient.

Claims

1. An elongate catheter for use in the treatment of a patient, said catheter comprising:

an elongate and tubular catheter body portion formed by a circumferential sidewall and having a longitudinal axis and distal and proximal end portions thereon;

a hub member attached to said body portion at said proximal end portion thereof;

said hub member including a generally tubular body portion thereof;

at least one loop member having a cross sectional dimension and first and second end portions integral with said tubular body portion of said hub member to form an enclosed opening between said tubular body portion of said hub member and said at least one loop member such that said opening defines an area which is greater than said cross sectional dimension of said at least one loop member to form an enlarged securement area therebetween.

2. The elongate catheter of claim 1 wherein said tubular body portion is a generally elongate and cylindrical member and said at least one loop member extends laterally therefrom.

3. The elongate catheter of claim 2 wherein said tubular body portion includes an outer diameter and said at least one loop member extends laterally from said tubular body portion a distance which is greater than said diameter of said tubular body portion.

4. The elongate catheter of claim 1 wherein said at least one loop member is generally U-shaped.

5. The elongate catheter of claim 1 wherein said area of said opening is approximately twice the cross-sectional dimension of said at least one loop member.

6. The elongate catheter of claim 1 wherein said at least one loop member includes at least a portion thereof which extends laterally from said tubular body portion and said area of said opening is approximately twice the cross-sectional dimension of at least said laterally extending portion of said at least one loop member.

7. The elongate catheter of claim 1 wherein said tubular body portion has a cross-sectional area which is greater than said cross-sectional dimension of said at least one loop member.

8. An elongate catheter for use in the treatment of a patient, said catheter comprising:

an elongate and tubular catheter body portion formed by a circumferential sidewall and having a longitudinal axis and distal and proximal end portions thereon;

a hub member having a tubular portion and an outer diameter and said tubular portion of said hub member is attached to said body portion at said proximal end portion thereof;

at least one loop member integral with said tubular portion of said hub member and having a cross sectional area and extending laterally from said tubular portion of said hub member to form an enclosed opening between said tubular portion of said hub member and said at least one loop member having an area therebetween such that said at least one loop member extends laterally from said tubular portion of said hub member a greater distance than the outer diameter of said tubular portion of said hub member to form an enlarged securement area therebetween and the area of said opening is greater than said cross sectional area of said at least one loop member.

9. The elongate catheter of claim 8 wherein said at least one loop member consists of a pair of loop members extending laterally from said tubular portion.

10. The elongate catheter of claim 8 wherein said at least one loop member is generally U-shaped.

11. The elongate catheter of claim 8 wherein the area of said opening is greater than twice said cross sectional area of said at least one loop member.

12. The elongate catheter of claim 8 wherein said area of said opening is greater than four times said cross sectional area of said at least one loop member.

13. The elongate catheter of claim 8 wherein said tubular portion has a cross sectional area which is greater than said cross sectional area of said at least one loop member.

14. An elongate catheter for use in the treatment of a patient, said catheter comprising:

an elongate and tubular catheter body portion formed by a circumferential sidewall and having a longitudinal axis and distal and proximal end portions thereon;

a hub member including a generally tubular portion and wherein said hub member is attached to said body portion at said proximal end portion thereof; and

at least one generally U-shaped loop member integral with said tubular portion of said hub member and having distal and proximal end portions connected to said hub member and a cross sectional area and wherein said at least one generally U-shaped member extends laterally from said tubular portion of said hub member to form a generally U-shaped and enclosed securement area between said tubular portion of said hub member and said at least one U-shaped loop member.

15. The elongate catheter of claim 14 wherein said securement area forms an opening having an area which is greater than said cross sectional area of said at least one U-shaped loop member to form said enlarged securement area therebetween.

16. The elongate catheter of claim 14 wherein said at least one U-shaped loop member consists of a pair of generally U-shaped loop members which each extend laterally from said tubular portion and said pair of generally U-shared loop members include a generally circular cross section.

17. The elongate catheter of claim 14 wherein the area of said securement area is greater than twice said cross sectional area of said at least one loop member.

18. An elongate catheter for use in the treatment of a patient, said catheter comprising:

an elongate and tubular catheter body portion formed by a circumferential sidewall and having a longitudinal axis and distal and proximal end portions thereon;

a hub member including a generally tubular portion and wherein said hub member is attached to said body portion at said proximal end portion thereof;

at least one generally U-shaped loop member having distal and proximal end portions integral with said tubular portion of said hub member and a cross sectional area and wherein said at least one generally U-shaped member extends laterally from said tubular portion of said hub member to form a generally U-shaped and enclosed securement area between said tubular portion of said hub member and said at least one U-shaped loop member; and

wherein said tubular portion is a generally elongate and cylindrical member and said at least one U-shaped loop member includes a pair of U-shaped loop members which each extend laterally from said hub member.

19. The elongate catheter of claim 18 wherein said tubular portion includes an outer diameter and said pair of U-shaped loop members extend laterally from said tubular portion a distance which is greater than said outer diameter of said tubular portion.

20. An elongate catheter for use in the treatment of a patient, said catheter comprising:

an elongate and tubular catheter body portion formed by a circumferential sidewall and having a longitudinal axis and distal and proximal end portions thereon;

a hub member attached to said body portion at said proximal end portion thereof and said hub member including a generally elongate and cylindrical tubular portion thereon and said tubular portion having an outer diameter; and

a pair of generally U-shaped loop members having a cross sectional dimension and being integral with and extending laterally from said tubular portion of said hub member to form a plurality of enclosed openings between said tubular portion of said hub member and said loop members such that of each of said openings defines an area which is greater than said cross sectional dimension of said loop members and said loop members extend laterally from said tubular portion of said hub member a greater distance than said outer diameter of said tubular portion to form an enlarged securement area therebetween.
