The invention relates to a percutaneous gastrostomy probe comprising a tube (1), a means of internal retention (2) and an external collar (3). The probe according to the invention is characterized essentially in that the means of internal retention (2) consists of a non-biodegradable inflatable balloon (21) connected to separate anchorage means (22) held in place by threads (23) sutured to external points (24) and made entirely of a biodegradable polymer or copolymer such that the nature of the polymers employed, their dosage and their number molar mass are determined in such a way as to obtain a connection which maintains its mechanical properties of retention until the stomach and abdominal walls have adhered together. |
