Abstract: A device for implanting at least one object beneath the skin of a patient includes a handle for grasping the device during insertion of an object. The handle may have a distal end, a proximal end, and an angled track formed on the handle. The angled track may have a stop at the distal portion that permits securing of the actuator and locks the cannula in a loaded position. A base may be connected to the handle. The base may include a post longitudinally fixed to the handle. The post may extend from the distal end of the handle. A hollow cannula may be positioned coaxially around and longitudinally slidable over the post from an extended position, in which at least one object is retained in the cannula, to a retracted position, in which at least one object is released from the cannula. A flexible actuator may be slidably engaged to the cannula to move the cannula from the extended position the retracted position to release the object from the cannula.

Abstract: A device for inserting implantable objects beneath the skin of a patient includes a handle for grasping the device and a base connected to the handle. The base comprises a post, a cannula, and a flexible actuator positioned in an angled track. The cannula is positioned coaxially around and is longitudinally slidable over the post from an extended position, where an implantable object is retained in the cannula, to a retracted position, where the implantable object is released from the cannula. A flexible actuator positioned on an angled track in the base is slidably engaged with a boss on the cannula and is used to move the cannula from an extended position to a retracted position to release the implantable object from the cannula; the actuator flexes between a locked and an unlocked position. The angled track provides for control of the release of the implantable object.

Abstract: This invention is related to the use of polyurethane based polymer as a drug delivery device to deliver biologically active compounds at a constant rate for an extended period of time and methods of manufactures thereof. The device is very biocompatible and biostable, and is useful as an implant in patients (humans and animals) for the delivery of appropriate bioactive substances to tissues or organs. The drug delivery device for releasing one or more drugs at controlled rates for an extended period of time to produce local or systemic pharmacological effects comprises: 1. a reservoir, said reservoir comprising; 2. at least one active ingredient; and, optionally, 3. at least one pharmaceutically acceptable carrier; a polyurethane based polymer completely surrounding the reservoir.
