Abstract
An implantation device for delivering a biosensor to an implantation site in a patient's body comprises an elongate catheter equipped with a distally located cavity sized to house a biosensor. Once the distal end of the catheter is positioned adjacent the implantation site, the biosensor is released through an opening from the cavity into the site. A removable cover, such as a thin adhesive film, may be used to retain the biosensor in the cavity, while the catheter is guided through the body to the implantation site. The implantation device may include an actuator for displacing the biosensor from the cavity into the implantation site. By way of one example, the actuator may be a piston inserted through a lumen of the catheter.
