An implantable elongated member configured to deliver a therapy from a medical device to a target therapy delivery site includes an inflatable balloon fixation element composed at least in part of a biocompatible degradable material. A biocompatible fluid may be delivered to the balloon fixation element via an inflation lumen in order to inflate the balloon upon implantation of the elongated member to fix the elongated member proximate to the target therapy delivery site. The balloon fixation element may be formed of a degradable material and deteriorate over time, such as in response to fibrous tissue growth.
