Patent ID: 7725179

Claim:
A catheter, in particular for insertion of heart-pacemaker- or ICD-electrodes into a patient's body, comprising a catheter wall, which defines at least one lumen, said catheter wall having a longitudinal dimension and said lumen extending in the direction of the longitudinal dimension; and a reinforcement in an axial and peripheral direction in the catheter wall for stabilization of the catheter in torsional and/or buckling strength; wherein the reinforcement is a profile element which is adjusted to desired mechanical properties of the catheter in the axial and peripheral direction thereof, wherein, at least along one sectional length, the profile element is a lattice profile element, and wherein the lattice profile element comprises: peripheral ribs in a form of partial rings that extend transversely to the longitudinal dimension, each peripheral rib having two opposed ends; and two axially continuous axial ribs that extend in the direction of the longitudinal dimension and that are each connected to a respective end of each of said peripheral ribs, said axial ribs being spaced apart in a direction transverse to the longitudinal dimension such that a gap is left between the two axial ribs, serving in the catheter as a pre-determined breaking point for the catheter to be torn open and the inserted electrode to be removed.
