EP-4739259-A1 - INTERNAL OSTOMY BAG

Abstract

An ostomy bag device (102) includes an expandable reservoir (104) extending from a first end (110) to a second end (112) and defining a space therewithin. The device also includes first and second connectors (106, 108). The first connector is connected to the first end and engages an opening extending through a wall at an end of an intestine so that intestinal contents flowing from the end of the intestine are received and collected within the reservoir. The second connector is connected to the second end and engages an exit location via which contents collected within the reservoir are to be drained to an exterior of a patient body. The second connector includes a control element (122) movable between a closed configuration, in which contents of the reservoir are prevented from flowing therepast, and an open configuration, permitting contents to flow therepast to drain the reservoir.

10. 10. The device of any one of claims 1-9, wherein the reservoir is deformable from an initial, unexpanded configuration toward an expanded configuration as the intestinal contents are received therein.
11. 11. A system, comprising: a bag device including an expandable reservoir, a first end of the expandable reservoir configured to be connected to an end of an intestine via a first connector so that intestinal contents flowing from the end of the intestine are received and collected within the expandable reservoir, and a second end of the expandable reservoir configured to be connected to an exit location via a second connector so that the intestinal contents collected within the expandable reservoir are to be drained to an exterior of a patient body, the second connector including a control element movable between a closed configuration, in which contents of the reservoir are prevented from flowing therepast, and an open configuration, in which contents of the reservoir are permitted to flow therepast to drain the expandable reservoir; and a delivery device extending longitudinally and including a channel extending therethrough, the bag device insertable through the channel to a target location within a user body.
12. 12. The system of claim 11, further comprising: a puncturing device configured to form an opening through a wall of the intestine to which one of the first and second connectors of the bag device is to be engaged.
13. 13. The system of any one of claims 11 -12, wherein the bag device includes a sensor positioned along the reservoir, the sensor configured to detect a fill level of the reservoir.
14. 14. The system of any one of claims 11-13, wherein one of the first connector and the second connector includes a self-expanding mesh coil.
15. 15. The system of any one of claims 11-14, wherein the control element includes one of a valve and an artificial sphincter.

Description

Internal Ostomy Bag Inventors: Gonzalo Jose SAENZ VILLALOBOS, John Thomas FAVREAU, Seamus Finbarr O’SHAUGHNESSY, Gian Franco LOO FUCHS, and Kevin WOOD Priority Claim [0001] The present disclosure claims priority to U.S. Provisional Patent Application Serial No. 63/604,546 filed November 30, 2023; the disclosure of which is incorporated herewith by reference. Field [0002] The present disclosure relates to ostomy devices and, in particular, relates to an internal ostomy bag configured to receive and collect intestinal contents therein. Background [0003] Ostomy procedures (e.g., colostomy, ileostomy) are performed for various patients with diseased or damaged bowels including, for example, colorectal cancer and diverticular disease or to treat issues in the urinary tract. Current ostomy procedures include re-routing a part of the colon (or small intestine) to drain outside of the body by bringing an end of the colon to the abdominal wall, where edges of the colon are stitched to the skin to form an opening called a stoma and/or urostomies in which a portion of an organ such as the small intestine is resected and coupled from the urinary tract (e.g., the ureters) to a stoma to permit the drainage of urine therethrough. Waste is then able to drain from the stoma into a bag or pouch attached to the abdomen. However, ostomy procedures often result in post-operative complications and/or patient discomfort including, for example, leakage, odor, skin irritation from attachment of the ostomy bag, and social anxiety. Summary [0004] The present disclosure claims priority to an ostomy bag device. The device includes an expandable reservoir and first and second connectors. The reservoir extends from a first end to a second end and defines a space therewithin. The first connector is connected to the first end of the reservoir and configured to engage an opening extending through a wall at an end of an intestine so that intestinal contents flowing from the end of the intestine are received and collected within the reservoir. The second connector is connected to the second end of the reservoir and configured to engage an exit location via which contents collected within the reservoir are to be drained to an exterior of a patient body. The second connector includes a control element movable between a closed configuration, in which contents of the reservoir are prevented from flowing therepast, and an open configuration, in which contents of the reservoir are permitted to flow therepast to drain the reservoir. [0005] In an embodiment, the device further includes a sensor positioned along the reservoir and configured to detect a level of fill thereof. [0006] In an embodiment, the sensor includes one of a pressure sensor and a deformation sensor. [0007] In an embodiment, one of the first connector and the second connector includes a selfexpanding mesh coil. [0008] In an embodiment, the self-expanding mesh coil includes a first flange at a first end thereof and a second flange at a second end thereof, the first and second flanges configured to receive a portion of the wall of the intestine therebetween. [0009] In an embodiment, one of the first and second connectors is connected to the first and second ends of the reservoir, respectively, via a tubing. [0010] In an embodiment, the control element includes one of a valve and an artificial sphincter. [0011] In an embodiment, the reservoir is formed of a biocompatible and expandable material. [0012] In an embodiment, the biocompatible and expandable material includes silicone. [0013] In an embodiment, the reservoir is deformable from an initial, unexpanded configuration toward an expanded configuration as the intestinal contents are received therein. [0014] In addition, the present disclosure relates to a system. The system has a bag device including an expandable reservoir, a first end of the expandable reservoir configured to be connected to an end of an intestine via a first connector so that intestinal contents flowing from the end of the intestine are received and collected within the expandable reservoir, and a second end of the expandable reservoir configured to be connected to an exit location via a second connector so that the intestinal contents collected within the expandable reservoir are to be drained to an exterior of a patient body, the second connector including a control element movable between a closed configuration, in which contents of the reservoir are prevented from flowing therepast, and an open configuration, in which contents of the reservoir are permitted to flow therepast to drain the expandable reservoir. [0015] The device also includes a delivery device extending longitudinally and including a channel extending therethrough, the bag device insertable through the channel to a target location within a user body. [0016] In an embodiment, the system further includes a puncturing device configured to form an opening through a wall of an intestine to which
