US Patent 7588560 Female catheter

A catheter includes a urinary tube having proximal and distal ends intercoupling a passage for receiving the discharge of urine from the urethera with the urinary tube distal end for coupling to a collection means. A resilient and deformable flared flange member is formed integral with the proximal end of the urinary tube, has a centered port contiguous with the urinary tube passage, has a peripheral edge that at least in part defines an annular proximal facing contact surface and an opposed annular distal facing contact surface. The peripheral edge covers an area that is greater than the cross-sectional area of the urinary tube. An adhesive component is disposed on the annular proximal facing contact surface.
