CURVED CATHETER
First Claim
1. Apparatus comprising:
- a medical device that is configured to be inserted into a body of a subject; and
a catheter that defines a continuous tube that defines a lumen therethrough, the medical device being configured to be inserted into the subject'"'"'s body via the catheter, the continuous tube comprising at least first, second, third, fourth, and fifth portions thereof,the first portion being disposed at a first end of the catheter and being shaped, when the catheter is in a non-constrained configuration, to define a cylindrical portion of the tube that defines a generally straight central longitudinal axis;
the second portion being disposed adjacent to the first portion and being shaped, when the catheter is in the non-constrained configuration, to define a curved cylindrical portion of the tube, a curvature of the second portion being such that a central longitudinal axis of the second portion defines a curve that is concave in a given direction, and that curves outwardly away from the central longitudinal axis of the first portion;
the third portion being disposed between the second and the fourth portions and being shaped, when the catheter is in the non-constrained configuration, to define a curved cylindrical portion of the tube, a curvature of the third portion being such that a central longitudinal axis of the third portion defines a curve that is convex in the given direction, and that curves inwardly toward the central longitudinal axis of the first portion, such that the central longitudinal axis of the third portion meets the central longitudinal axis of the first portion,the fourth portion being disposed between the third and the fifth portions of the tube, and being shaped, when the catheter is in the non-constrained configuration, to define a curved cylindrical tube, a curvature of the fourth portion being such that a central longitudinal axis of the fourth portion defines a curve that is concave in the given direction, and that curves away from the central longitudinal axis of the first portion,the fifth portion being disposed at a second end of the catheter the fifth portion being shaped, when the catheter is in the non-constrained configuration, to define a curved cylindrical tube, a curvature of the fifth portion being such that a central longitudinal axis of the fifth portion defines a curve that is concave in the given direction, and that curves inwardly toward the central longitudinal axis of the first portion.

Abstract
Apparatus and methods are described including inserting a catheter into a subject'"'"'s body via a vein of the subject'"'"'s groin. The catheter is advanced distally such that a distal end of the catheter is disposed inside the subject'"'"'s renal vein. Respective stabilizing portions of the catheter stabilize the catheter by being in contact with inner walls of, respectively, an iliac vein of the subject, and a vena cava of the subject. Subsequently, a medical device is deployed inside the renal vein by retracting the distal end of the catheter, such that the distal end of the catheter is in a retracted state, in which the respective stabilizing portions of the catheter still stabilize the catheter by being in contact with the inner walls of, respectively, the subject'"'"'s iliac vein and the subject'"'"'s vena cava. Other applications are also described.
