Abstract

Abstract A double catheter assembly is provided which includes two single lumen catheters that pass through the center portion of a stabilizer disk in a juxtaposed relationship. The stabilizer disk may be provided with holes in its periphery that facilitate suturing of the disk to a patient's skin at the insertion site, once the catheter is implanted. The portions of the catheters that are external to the insertion point are characterized by having a permanent bend proximate to the stabilizer disk that promotes patient compliance when the double catheter assembly is used in a catheterization.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 174 words
A double catheter assembly useful for vascular access which comprises: two single lumen catheters, each having an external portion and an implantable portion along their respective lengths; a stabilizer disk having opposed surfaces through which each of the two catheters pass at a transition point along the catheter lengths between the external portions and the implantable portions, said transition point being located for externally attaching said disk to a patient's skin; said catheters passing through holes formed transversely through said disk and being secured within said holes of the disk in a juxtaposed and parallel relationship with each other at a centrally located portion of the disk; and each of said catheters having a heat set bend in the external portion of each of said catheters proximate to the stabilizer disk, said bends having sufficient radius of curvature for avoiding constriction of the catheter lumens and being at an angle for facilitating placement and routing of the external portions of the catheters remote from the bends next to a patient's skin during a catheterization.
Claim 2
Dependent Claim 174 words
A double catheter assembly useful for vascular access which comprises: two single lumen catheters, each having an external portion and an implantable portion along their respective lengths; a stabilizer disk having opposed surfaces through which each of the two catheters pass at a transition point along the catheter lengths between the external portions and the implantable portions, said transition point being located for externally attaching said disk to a patient's skin; said catheters passing through holes formed transversely through said disk and being secured within said holes of the disk in a juxtaposed and parallel relationship with each other at a centrally located portion of the disk; and each of said catheters having a heat set bend in the external portion of each of said catheters proximate to the stabilizer disk, said bends having sufficient radius of curvature for avoiding constriction of the catheter lumens and being at an angle for facilitating placement and routing of the external portions of the catheters remote from the bends next to a patient's skin during a catheterization.
Claim 3
Dependent Claim 31 words
The double catheter assembly according to claim 1, wherein the catheters pass through and are secured within said holes of the disk in a substantially vertical orientation to the disk surfaces.
Claim 4
Dependent Claim 26 words
The double catheter assembly according to claim 2, wherein the bend in the external portion of each of said catheters is substantially a right angle bend.
Claim 5
Dependent Claim 20 words
The double catheter assembly according to claim 1, wherein the double catheter assembly is made of a soft flexible material.
Claim 6
Dependent Claim 15 words
The double catheter assembly according to claim 4, wherein the material is an elastomeric polymer.
Claim 7
Dependent Claim 16 words
The double catheter assembly according to claim 4, wherein the material is polyurethane or silicone rubber.
Claim 8
Dependent Claim 24 words
The double catheter assembly according to claim 1, wherein the single lumen catheters are independent, separate catheters that are not conjoined along their lengths.
Claim 9
Dependent Claim 21 words
The double catheter assembly according to claim 1, wherein the respective implantable portions of the two catheters are of different lengths.
Claim 10
Dependent Claim 25 words
The double catheter assembly according to claim 1, wherein the stabilizer disk contains a plurality of holes adjacent to the perimeter of the stabilizer disk.
Claim 11
Dependent Claim 18 words
The double catheter assembly of claim 1, wherein the external surfaces of the stabilizer disk are metallic silver.
Claim 12
Dependent Claim 27 words
The double catheter assembly according to claim 1, further comprising connectors located at the ends of the external portions of the catheters remote from the stabilizer disk.
Claim 13
Dependent Claim 20 words
The double catheter assembly according to claim 1, wherein the catheters are permanently secured within the holes of the disk.
Claim 14
Dependent Claim 158 words
A double catheter assembly useful for vascular access which comprises: two single lumen catheters, each having an external portion and an implantable portion along their respective lengths; a stabilizer disk having opposed planar surfaces through which each of the two catheters pass at a transition point along the catheter lengths between the external portions and the implantable portions, said transition point being located for externally attaching said disk to a patient's skin; said catheters passing through holes formed transversely through said disk and being secured within said holes of the disk in a juxtaposed and parallel relationship with each other at a centrally located portion of the disk in a substantially perpendicular orientation to the disk planar surfaces; and each of said catheters having a heat set right angle bend in the external portion of each of said catheters proximate to the stabilizer disk, said bends having sufficient radius of curvature for avoiding constriction of the catheter lumens.
Claim 15
Dependent Claim 158 words
A double catheter assembly useful for vascular access which comprises: two single lumen catheters, each having an external portion and an implantable portion along their respective lengths; a stabilizer disk having opposed planar surfaces through which each of the two catheters pass at a transition point along the catheter lengths between the external portions and the implantable portions, said transition point being located for externally attaching said disk to a patient's skin; said catheters passing through holes formed transversely through said disk and being secured within said holes of the disk in a juxtaposed and parallel relationship with each other at a centrally located portion of the disk in a substantially perpendicular orientation to the disk planar surfaces; and each of said catheters having a heat set right angle bend in the external portion of each of said catheters proximate to the stabilizer disk, said bends having sufficient radius of curvature for avoiding constriction of the catheter lumens.
Claim 16
Dependent Claim 20 words
The double catheter assembly according to claim 13, wherein the catheters are permanently secured within the holes of the disk.
Claim 17
Dependent Claim 168 words
A double catheter assembly useful for acute catheterization procedures which comprises: two single lumen catheters, each having an external portion and an implantable portion along their respective lengths; a stabilizer disk having opposed planar surfaces through which each of the two catheters pass at a transition point along the catheter lengths between the external portions and the implantable portions, said transition point being located for externally attaching said disk to a patient's skin; said catheters passing through holes formed transversely through said disk in a substantially juxtaposed and parallel relationship with each other at a centrally located portion of the disk; and each of said catheters having a heat set bend in the external portion of each of said catheters proximate to the stabilizer disk, said bends having sufficient radius of curvature for avoiding constriction of the catheter lumens and being at an angle for facilitating placement and routing of the external portions of the catheters remote from the bends next to a patient's skin during a catheterization.
