1. A medical microelectrode bundle comprising at least two medical microelectrodes configured to be inserted into soft tissue, each medical microelectrode comprising:

  • an electrically conducting elongate electrode body comprising a first proximal end, and a second distal end, the electrode body comprising;

    a tip section extending from the distal end;

    a main body section extending in a proximal direction from the tip section,wherein the tip section, and the main body section are embedded in a first electrode matrix section, which is substantially rigid, biocompatible and soluble or biodegradable in a body fluid; and

    a second electrode matrix section comprising at least one of a sugar and agarose, and positioned such that at least a significant part of the first electrode matrix section is positioned between the second electrode matrix section and the electrode main body,wherein a drug configured to be released upon dissolution or biodegradation of the first electrode matrix element section comprises the first electrode matrix section or the second electrode matrix section,wherein the at least two medical microelectrodes comprise electrode bodies substantially disposed in parallel and sharing said first electrode matrix section.
