Abstract: Insulin injection syringes are disclosed that include two types of components, namely, durable components that that do not contact the fluid path and can be reused, and disposable or single-use components that contact the fluid path and are not reused. The durable components do not contact the fluid path so that sterility is not affected. Two different syringe components include a reusable outer sleeve containing scale markings for the syringe and a reusable syringe plunger are provided as durable components in embodiments of the present invention. Syringes manufactured according to the present invention can employ one or both of these durable components. Methods for making, using and packaging such syringes are also disclosed.

Abstract: Induction heating from an induction coil (108) is used to separate a metal medical sharp (144) from its holder (142) by applying a high-frequency oscillating magnetic field that excites eddy currents and resistance heating in the sharp. The heated metal sharp melts the adhesive or plastic securing the sharp to its holder. The use of induction heating is advantageous in that it does not require direct contact between the electrical circuit and the sharp or its holder. The heating can also act to sterilize the sharp and thereby render it less hazardous at the same time that it separates the sharp from its holder. The induction coil can have a stepped or conical shape to concentrate the RF energy at the interface between the metal sharp and its holder.

Abstract: A medical device such as a cannula, catheter, needle or biosensing probe includes an elongated body for penetrating, inserting and/or positioning in or through the skin of a patient. The elongated body has an outer surface that when positioned in the patient with a coefficient of friction sufficient to inhibit movement between the elongated body on the skin at the insertion site to inhibit irritation at the infusion site. A lubricious coating is provided on the elongated body to assist in penetration and/or insertion of the elongated body into the patient. The lubricious coating can be removed by a shearing action by the insertion of the elongated body into the patient and/or by absorption of the lubricious coating to expose the outer surface of the elongated member.

Abstract: User-friendly attachment mechanisms for pen needles provide improved handling and ease of use, including locking installation and removal features and sensory feedback when a needle-bearing hub is seated on a pen. Embodiments include a needle-bearing hub having a circumferentially oriented flexible tab that engages a radially inward rib on an outer cover to assist in attaching a pen device to the pen needle.

Abstract: A syringe with adjustable penetration depth, comprising a tubular syringe barrel, a plunger positioned within the syringe barrel, a hub bearing a needle and attached to the syringe barrel, a movable collar having an open proximal end received over the hub, a distal end wall having an opening through which the needle protrudes, and a sidewall extending proximally from the distal end wall, the sidewall having an interior surface engaging the hub or syringe barrel, and a retaining feature on the collar engaging the hub or barrel and retaining the collar at a plurality of axial positions. The collar travels with respect to the hub along a path defined by the retaining feature on the interior surface of the sidewall engaging the hub or barrel, exposing a greater length of the needle as the collar travels toward the plunger.

Abstract: An injection device is provided for delivering a liquid medicament. The injection device includes a housing with a first chamber for storing a supply of the medicament. The first chamber and a second chamber are coupled within the housing. The second chamber is in fluid communication with the first chamber. The system also includes an outlet port for dispensing the medicament outside the housing. The outlet port is coupled to the housing and in fluid communication with one of the first and second chambers.
