Abstract: An infusion device, including: a housing; an infusion cannula extending downwardly away from the housing and capable of receiving an insertion needle; a septum disposed in the housing; a passageway under said septum and in fluid communication with said cannula; and, an infusion needle insertable through the septum, the infusion needle capable of penetrating the septum and entering said passageway thereby forming a flow path between the infusion needle and the infusion cannula and wherein the ion cannula and the infusion needle are aligned on separate non identical axes.

Abstract: A system for inserting at least a portion of an insertion set through the surface of a tissue, having: an inserter with a moveable plunger disposed within a cavity therein; an insertion set holder received into the distal end of the cavity; and an insertion set received into the insertion set holder, wherein the insertion set is moveable within the insertion set holder such that when the plunger is advanced into contact with the insertion set, the insertion set advances through the insertion set holder to a position at which at least a portion of the insertion set extends out of the distal end of the cavity.

Abstract: An infusion hub assembly, comprising: a hub received in a hole in a wing, the hub having a bore passing therethrough, with an upper portion of the circular hub having an attachment surface thereon; an infusion cannula extending downwardly away from the wing, the infusion cannula being in fluid communication with the bore passing through the hub; a cover having a bore passing therethrough and having an inner attachment surface adapted to mate with the attachment surface on the upper portion of the hub; and a septum positioned in alignment with the bore passing through the cover.

Abstract: The infusion set comprises of a connecting tube of polyethylene which is treated to form a wetable surface or treated with a primer and then bonded to a PVC hub by using solvent adhesive to solvent bond the low density polyethylene tubing or Teflon tubing to a PVC hub. The surface treatment methods include a methane plasma surface that is applied to tubing in a continuous manner and alternatively a primer that is applied locally and dried prior to applying the adhesive. Both techniques form a strong and resilient bond for the infusion needle and tube when assembled to the PVC hubs.

Abstract: An infusion pump includes a plurality of projections configured so that they enter the subcutaneous region of the patients skin and provides a painless means of creating a breach in the stratum corneum which is sealed against leakage by the skin surrounding each projection and provides a flow path for either a basal and bolus injection of medication. The pump includes a drug reservoir containing a drug. The pump includes a microactuator and includes a housing having a foundation or lid which opens and closes so that the medication container can be inserted and supported in a delivery mode position. A micro actuator is used to advance either a roller or a piston in communication with the medication container. Attached to the micro-actuator is a device that is mounted for movement along the access of the medication container. The device indexes along the medication container that is used to dispense the medication.

Abstract: A medication injection or delivery system is provided for injecting fluids such as insulin within body tissue. The device includes a housing, a flexible shaft movably mounted within the housing, and a dose setting mechanism for controlling the movement of the shaft with respect to a fluid-containing cartridge removably positioned within or mounted to the housing. The flexible shaft, according to exemplary embodiments, includes a plunger and a flexible cable connected to the dose setting mechanism. The plunger and dose setting mechanism are connected together by the flexible shaft. The dose setting mechanism, in one aspect of the invention, includes a screw, a locking mechanism, and a nut assembly connected to the flexible shaft. The dose setting mechanism is used to set the dosage and prime the catheter. The plunger retracts into a recess to permit a new cartridge to be installed quickly.

Abstract: An infusion pump for use with standard pre-filled medication container and a drug delivery device for percutaneously administering a drug. The delivery device having a plurality of projections and a drug reservoir. The projections extend from the reservoir and are adapted for penetrating the stratum comeun for percutaneously administering a drug from the reservoir to produce a local or systemic physiological or pharmacological effect. The plurality of projections is formed by micro machining. The pump is made by using a micro-actuator and includes a housing having a lid which opens and closes so that the medication container can be inserted and supported in a delivery mode position.
