Methods, apparatuses and systems for collecting cells from a body lumen are described. The anchor is moved into the opening formed in the bone in the patient’s body with a suture connected to the anchor. The flexible conductor includes at its free end an alignment structure that provides a separable, low loss interface to an alignment structure coupled to the waveguide on the other board. The method and system further includes providing a grammar for allowing resources to be defined and managed, a grammar for allowing the resource-needs to be defined and managed, a grammar providing definition of code blocks, and a grammar for associating resources with code blocks. Each module preferably includes an additional locating mechanism to allow an additional module to be located by the additional locating mechanism.
