Abstract
A percutaneous endoscopic gastrostomy device comprises a removable, dilating tip. The tip is located at the distal end of the device and provides for tissue dilation upon entry of the device into the body of a patient. The tip is lubricious and biodegradable. The tip is removable by dislodging it from the end of the device following placement of the device in the patient. The tip is usually dislodged by action of a physician to dislodge the tip, however it may be dissolved by application of a biocompatible solvent or through digestion. Following removal of the tip from the device, the tip is dissolved naturally by digestion.
