Active, Reversible Fixing of CRT Electrodes

摘要

An implantable medical electrode device includes an elongate electrode line with a tubular electrode body, having a hollow, passing from the proximal to distal ends, an electrode provided at the distal end, and an electrode connection provided at the proximal; a fixing device with a balloon catheter arrangement, having an elongate tubular hollow catheter body with an outer diameter smaller than the inner diameter of the hollow of the electrode body, and an inflatable balloon at the distal end, with an outer diameter smaller in the deflated state compared to the inner diameter of the hollow of the electrode body, and a fluid connection at the proximal end adapted to the electrode connection of the electrode body; connection means for releasable connection of the electrode line to the fixing device; and sealing means for fluid-tight closure of the catheter body of the fixing device in an inflated balloon state.

1. An implantable medical electrode device adapted for insertion into a blood vessel, comprising:
an elongate electrode line with a tubular electrode body, which has a hollow, passing from a proximal end to a distal end, with an inner diameter, and at the distal end of which one or more electrodes are provided, and at the proximal end of which an electrode connection is provided; a fixing device with a balloon catheter arrangement, which has an elongate tubular hollow catheter body with an outer diameter that is smaller than the inner diameter of the hollow of the electrode body, and an inflatable balloon at, or close to, the distal end, with an outer diameter smaller in a deflated state compared to the inner diameter of the hollow of the electrode body, and a fluid connection and electrode connection at the proximal end, which is adapted to the electrode connection of the electrode body; connection means for releasable connection of the electrode line to the fixing device; and sealing means for fluid-tight closure of the catheter body of the fixing device in its state of use with an inflated balloon.
