Abstract
Abstract A gastrostomy device including an elongate feeding tube having a first end for insertion through an opening in a patient's abdominal wall and a second end including a feeding inlet. An inflatable balloon is mounted near the first end and a leakage seal valve is connected adjacent the balloon. The seal valve includes a flexible, elastomeric member to seal the opening in the patient and prevent leakage.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A gastrostomy device comprising an elongated feeding tube having a first end for insertion through a patient's abdominal wall and a second end including a feeding inlet, an inflatable balloon mounted on said feeding tube near said first end, a fluid supply conduit near said second end in communication with said balloon, wherein said balloon can be inflated upon correct positioning of said first end within the patient and a leakage seal valve connected to said first end adjacent said balloon, said leakage seal valve including a flexible, elastomeric member mounted adjacent said balloon to seal the opening in the patient and prevent leakage upon inflation of said balloon.
Claim 2
Dependent Claim
109 words
A gastrostomy device comprising an elongated feeding tube having a first end for insertion through a patient's abdominal wall and a second end including a feeding inlet, an inflatable balloon mounted on said feeding tube near said first end, a fluid supply conduit near said second end in communication with said balloon, wherein said balloon can be inflated upon correct positioning of said first end within the patient and a leakage seal valve connected to said first end adjacent said balloon, said leakage seal valve including a flexible, elastomeric member mounted adjacent said balloon to seal the opening in the patient and prevent leakage upon inflation of said balloon.
