Apparatus are provided for accessing andor removing material from a body lumen. The method includes providing a substrate, forming a first material layer on the substrate, forming a second material layer on the first material layer and forming a first PR layer on the second material layer. Coaxially with the inner conductor is disposed in a hollow space at least one pair of two lines, which form a connection between inner conductor and housing. The hybrid seals can be produced from hybrid heat resistant strips that can be wrapped into a preform and then compression molded to form the hybrid seal. Where blocks are shared between branches, dissemination areas are weighted according to the portion of customers associated with each branch.
