A device for delivering energy to a muscle may include a housing and at least one energy conduit associated with the housing. The at least one energy conduit may be configured to facilitate transfer of energy from an energy source that may be configured to provide energy to muscle within an organ. The device may further include a plurality of needles connected to the at least one energy conduit. Each needle may be configured to pierce tissue. The plurality of needles may include at least one needle configured to deliver energy through an energy emitting portion. The at least one needle may be sized so that when inserted into a wall of the organ, the energy emitting portion may be located within a muscle layer, and such that a majority of energy delivered via the at least one needle may be substantially confined to the muscle layer.
