Claim:
1. A system for controlling fluid flow within a host body comprising: a constricting member for allowing fluid flow within a body canal when in an open position and for reducing fluid flow within the body canal when in a closed position; an actuator for operating the constricting member between the open position and the closed position; and a control structure positioned within the host body having a housing, the housing comprising a first part and a second part, the first part of the housing further defining a void space for receiving one or more antenna, the control structure for operating the actuator, the control structure being operated by a telemetry device from a position outside the host body, wherein the control structure includes the one or more antenna for transmitting and receiving signals to and from the telemetry device, and wherein at least a portion of the one or more antenna projects beyond the second part of the housing and extends into the void space defined within the first part of the housing, and wherein a gap is further defined within the void space, wherein the gap is between the first part of the housing and the one or more antenna to provide the one or more antenna projecting therein with space such that the one or more antenna projecting therein do not contact the first part of the housing when the one or more antenna are subjected to vibrational movement.
