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. |

DETAILED DESCRIPTION OF THE INVENTION Certain terminology is used in the following description for convenience only and is not limiting.
The words "right," "left," "lower" and "upper" designate directions in the drawings to which reference is made.
The words "external" and "implantable" refer to regions along the length of the catheters that correspond to the respective portions that ordinarily are outside the patient's body and inside the patient's body when the device is used in a catheterization.
"Distal" and "proximal" refer to directions toward and away from respectively, the end of the catheter which is inserted in an area to be catheterized.
The terminology includes the words above specifically mentioned, derivatives thereof, and words of similar import.
Referring now to the drawings in detail, there is shown in FIGS.
1 through 5 a preferred embodiment of a double catheter assembly or device, generally indicated as 10.
As shown in FIG.
1, the principal components of the double catheter assembly 10 are two independent single lumen catheters 20, 30 and a stabilizer disk 40 that secures the two catheters 20, 30 together and serves to stabilize the catheter assembly 10 at the insertion point on a patient's body when the assembly is used in a catheterization, typically as shown in FIG.
5.
The catheters 20, 30 of this invention are also characterized by having permanent bends 23, 33 in the respective external portions 21, 31 of the catheters 20, 30 that are adjacent to the stabilizer disk 40 and that lie outside the patient's body when the catheter assembly 10 is used in a catheterization.
These and other aspects of the invention will now be described in more detail.
As shown in FIG.
1, the preferred assembly 10 according to the present invention is a dual catheter assembly which includes a first catheter 20, a second catheter 30, and a stabilizer disk 40.
It will be understood from the disclosure, that additional catheters (not shown), including triple and other multiple lumen catheter assemblies, which have implantable portions for inserting into the area to be catheterized in a manner as shown in FIG
