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, and wherein said second elongation property is greater than said first elongation property.

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.
