First Claim
Patent Images
1. An elongate catheter comprising:
- an elongate body portion formed by a circumferential sidewall and having a longitudinal axis with a lengthwise dimension and distal and proximal end portions thereon;
a first lumen in said body portion extending between said proximal end portion and a generally elongate side opening formed in said sidewall of said body portion;
said side opening formed in said sidewall of said body portion and in communication with said lumen, said side opening further including a first side thereon which is oriented diagonally with respect to said longitudinal axis of said body portion such that said side opening extends along a portion of said lengthwise dimension of said body portion and along said circumferential sidewall of said body portion; and
a plurality of spaced apart ends intersecting said first side including a distal and proximal end wherein said distal end is oriented distally of said proximal end along said longitudinal axis of said body portion and oriented generally parallel to said longitudinal axis of said body portion.

Abstract
An elongate catheter having one or more lumens therein and at least one lumen in flow communication with a side opening in the sidewall of the catheter wherein the side opening includes at least a first side which is oriented diagonally with respect to the longitudinal axis of the catheter and the first side intersects the septum of the catheter to form a side opening wherein the size of the area of the opening is maximized.

12. A method of inserting a catheter into a patient comprising:
-
forming an elongate catheter having a side opening therein wherein the side opening is oriented generally diagonal with respect to the longitudinal axis and includes a proximally located side thereon, and inserting the catheter into an incision of the patient with a rotational movement along the orientation of the proximally located side of the side opening such that the tissue of the patient contacts a distally positioned surface of the proximally located side before the tissue contacts a proximally positioned surface of the proximally located side of the side opening.
