Abstract
Abstract The invention relates to a catheter system comprising a totally implantable reservoir for a treating agent, and at least one catheter connected thereto. The reservoir is designed to have a variable volume so that it can be positioned in the tissue by a small cannula needle when its volume is small and can be brought to the required internal volume in situ.
