<p>A urethral catheter comprising a tube (10) having openings at both ends and at least a portion of the tube having a flexural wall formation permitting compliance of the wall with the urethral shape in use. Longitudinal flexion in the oval-shaped tube is reduced optionally by incorporating a thickened wall portion (12) extending along the catheter about the minor axis thereof, and/or flexural compliance in the lateral direction is reduced optionally by providing a thickened wall portion (17) about the major axis. The catheter is suitable for male patients, and the wall formation can be selected for satisfactory peformance under a number of different conditions.</p> |
