ABSTRACT:
A catheter with an adjustable, external locking bolster. The catheter is for insertion into a body and includes a distal tip which is positioned inside the body, and a tubular member which is in communication with the distal tip. A portion of the tubular member exists outside the body and is provided on its outer surface with engagement elements. An external coupling has matching engagement elements for selective, adjustable securement to the tubular member. A compression element is provided which locks the external coupling to the tubular element and prevents slippage. The adjustable engagement allows a low profile, close to the skin appearance, while the compression element securely locks the external coupling to the tubular member.
