Bowel management system and waste collection bag therefor
DC CAFCFirst Claim
1. A bowel management system comprising:
- a rectally inserted catheter having a first catheter section having a patient proximal opening that, when in position for normal use, is in a patient'"'"'s rectum to receive bowel waste, and a second catheter section located distal to the first section that, when in position for normal use, can be collapsed by a patient'"'"'s anal sphincter muscles;
the first catheter section being sufficiently pliable to permit folding for insertion into a patient'"'"'s rectum but following insertion permits flow of bowel waste through the patient proximal opening;
the second catheter section permitting passage of bowel waste from the patient and being sufficiently soft to permit retention within a patient'"'"'s anal canal for extended periods of time; and
a balloon coaxial with, and extending radially outward relative to, the patient proximal opening of the first catheter section for retaining the patient proximal opening in a position for normal use where it opens into the rectum of the patient, and the balloon having a proximal-most end coincident to a proximal-most first end of the first catheter section, the balloon having an inflated size sufficiently large so as to prevent migration of the first catheter section out of the patient'"'"'s rectum through the patient'"'"'s anal canal without being so large as to trigger a defecatory response in the patient.

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 50 A to about 90 A. The second catheter section is connected to the first section and has durometer hardness in the range of about 5 A to about 49 A. 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.

13. A bowel management system for use in a patient comprising:
-
a waste collection catheter having a first catheter section which is patient proximal and which is disposed in the patient'"'"'s rectum in a normal use position; the waste collection catheter also having a second catheter section which is positioned patient distal in normal use, the second catheter section being coated at least one of internally with a substance to facilitate flow-through of waste matter from the patient or externally with a substance to facilitate milking of the waste collection catheter by a caretaker for the patient; and a selectively collapsible retention balloon attached coaxially and exterior of the patient proximal first section, the balloon having a proximal-most end coincident to a proximal-most first end of the first catheter section. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
