description | An insertion and retraction device is described for delivery and removal of a microparticle from target tissue. The device comprises a magnetic or magnetizable needle or cannula having a distal end, a proximal end and a lumen adapted to convey microparticles; a tubular catheter receiving the needle or cannula; a pressure device adapted for delivery of microparticles through the needle or cannula lumen by pressure; a magnetic field modulator adapted to move the needle or cannula by modulation of a magnetic field; and a magnetic sensor positioned toward the distal end of the tubular catheter responsive to a magnetic moment of the microparticle. |
