1. A sling for insertion into a patient comprising:
- a surgical sling adapted to support the urethra in its normal anatomic position and to prevent abnormal urethral descent under intraabdominal pressure;
said surgical sling comprising a length of material having a longitudinal axis, and a latitudinal axis;
wherein said material has a first elongation property along said longitudinal axis, and a second elongation property along said latitudinal axis. said first and second elongation property being different from each other.

Abstract
The present invention relates to a sling, methods of making and using a sling, and kits comprising a sling for treating urinary incontinence. The sling has multiple elongation properties that serve to improve the support of the urethra. The sling may comprise a coated material adapted for urethral suspension. The coated sling has properties that appear to enhance the sling elongation characteristics. The coated sling further includes properties that reduce its susceptibility to bacterial infections. The sling further includes properties to enhance the proper tensioning of the sling.

18. A method of making a sling for treating urinary incontinence comprising:
-
providing a mesh material suitable for constructing a sling for supporting a urethra, said mesh having a first elongation property in a longitudinal direction and a second, different, elongation property in a latitudinal direction;
providing a coating dispersion;
coating said mesh material with said coating dispersion; and
manipulating said mesh material during said coating so as to create a predetermined value for said first and second elongation properties in said mesh material.

26. A sling for insertion into a patient comprising:
-
a surgical sling adapted to support the urethra in its normal anatomic position and to prevent abnormal urethral descent under intraabdominal pressure;
said surgical sling comprising a length of material having a longitudinal axis, and a latitudinal axis;
wherein said sling comprises a plurality of regions along its longitudinal axis and wherein each region contains differing elongation properties from an immediately adjacent region.

30. A method of restoring urethral anatomy in a patient suffering from urinary incontinence comprising the steps of:
-
providing a silicone coated sling, inserting a silicone coated sling into the patient'"'"'s pelvic cavity;
manipulating said sling so as to pass under a central region of the patient'"'"'s urethra;
attaching each end portion of the sling to a posterior/inferior region of a right and a left pubic bone of the patient; and
positioning the sling so as to restore and stabilize the urethra to a position that maintains urinary continence by orienting said sling such that said sling has a first elasticity in a direction spanning across the urethra and a second, different elasticity in a direction along the axis of said urethra. - View Dependent Claims (31, 32)

33. A method of placing a sling in a patient for the treatment of urinary incontinence comprising:
-
inserting a sling into the patient'"'"'s pelvic cavity, the sling having indicia capable or indicating tension in the sling;
manipulating said sling such that it passes underneath a central region of the patient'"'"'s urethra;
tensioning said sling until said sling achieves a predetermined tension as indicated by visual indicia present on said sling; and
,securing said sling within said patient. - View Dependent Claims (34, 35, 36, 37, 38, 40, 41, 42, 43, 44)

39. A sling suitable for use in a sling procedure to treat urinary incontinence comprising:
-
a mesh material having a predetermined length and a width;
said mesh material having predetermined elongation properties;
said mesh having a predetermined visual indicia present on said mesh corresponding to the presence of a predetermined tension in said sling, said predetermined visual indicia being absent from said mesh when said sling is free from tension.
