The LectraJet Needle-Free Injection System is intended to deliver subcutaneous (SQ) or intramuscular (IM) injections of vaccines and other injectable medications. The LectraJet Needle-Free Injection System may be used by physicians, nurses, veterinarians, podiatrists and other practitioners who routinely administer injections. The LectraJet Needle-Free Injection System may also be used by patients to self inject or to have other individuals administer injections of prescribed medications.

The components of the LectraJet® Needle-Free Injection System include the needle-free single-use syringes with disposable vial adapter and cap with plunger rod attached and the injector handpiece with manual reset mechanism. The LectraJet® handpiece and reset mechanism are sold as a complete injection system contained within a carrying case. The carrying case is an accessory of convenience that provides for portability, organization, and ease of use for the practitioner. The LectraJet® syringes are packaged sterile and designed to be filled by the end user at the time of use. The polycarbonate syringes have a molded orifice at the front end. The syringe orifice is available in sizes 0.006", 0.008", 0.010" and 0.012" diameter, which allows the user to choose the syringe appropriate for the desired depth of penetration (IM/SQ) and patient selection (child/adult). The syringes have a flange at the back end that is held by the injector handpiece when delivering the injection. Syringes are designed to be used immediately upon filling, similar to a traditional needle and syringe, and identical to the Biojector 2000® and Medi-Jector Vision® syringe filling philosophy. After the syringes are filled, they are inserted directly into the LectraJet® handpiece. The LectraJet® handpiece contains a spring drive system that, when compressed, provides the energy to deliver the injection. To compress the spring, the handpiece is placed in a manual reset mechanism and hand pressure is applied to the reset mechanism lever. In the Medi-Jector Vision®, the manual power source used to compress the spring is a hand-twist knob. In the Biojector 2000®, the power source is either a gas cartridge or a gas cylinder. When the LectraJet® handpiece is actuated, the spring drive system is released, and the handpiece ram contacts the syringe piston to drive the injectate out through the syringe orifice, creating a jet stream with enough energy to penetrate the tissue. This is identical in principle to the Biojector 2000® and the spring powered Medi-Jector Vision®. After the injection, the used syringe is released into an appropriate trash container. Little maintenance is required for the LectraJet® handpiece. There are no o-rings or seals to change. No sterilization of the handpiece is required. All of the above features are similar to the Biojector 2000® and the Medi-Jector Vision®, predicate devices and accessories.
