ABSTRACT:
A bowel management system includes a waste collection catheter having at least two distinct sections. The first section is patient proximal when disposed in the patient's rectum and has durometer hardness in the range of about 50A to about 90A. The second catheter section is connected to the first section and has durometer hardness in the range of about 5A to about 49A. A selectively collapsible, substantially spherical retention balloon is attached coaxially and exterior of the first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most end of the first section of the waste collection catheter, the substantially spherical retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient.
