Anchor delivery system

A method for delivering a plurality of anchor assemblies, comprising:

• removing an insert from a handle assembly;
• inserting a cartridge into the handle assembly, the handle assembly comprising an actuator and a drive mechanism comprising a spring mechanism having a first loaded configuration characterized by a total stored energy and an unloaded configuration, wherein removing in the insert loads the spring mechanism with the total stored energy,
• wherein the cartridge comprises at least one anchor assembly and a penetrating member and wherein the at least one anchor assembly and the penetrating member are configured to advance from a distal portion of the cartridge;
• positioning the distal portion of the cartridge at an interventional site adjacent a prostate;
• operating the actuator with a first actuation to cycle the drive mechanism from the loaded configuration to the unloaded configuration;
• operating the actuator with a second actuation to cycle the drive mechanism from the unloaded configuration to a second loaded configuration characterized by the total stored energy, wherein:
• operating the actuator with the first actuation simultaneously delivers a needle and at least a portion of the at least one anchor assembly to the prostate by transferring load from the drive mechanism to the cartridge, and
• operating the actuator with the second actuation delivers at least a second portion of the at least one anchor assembly to the prostate by transferring load from the drive mechanism to the cartridge;
• and
• removing the cartridge.
