Device for subcutaneous delivery of fluid medicament

An improved device delivers a fluid medicament to the subcutaneous tissue of a user. The device is better suited for patients with Parkinson's Disease and other central nervous system disorders, than conventional infusion devices. The device can include a reusable part including a drive component (e.g., motor) and control electronics and a disposable part including a medicament reservoir. Medicament can be evacuated from the medicament reservoir by a plunger assembly that includes a plunger attached to a lead screw that is rotated by a nut, all within the disposable part. The device can be fluidically coupled with the tissue via a flexible cannula. Various embodiments relate to an improved cannula insertion mechanism that delivers the cannula under a force applied by a spring. Various embodiments relate to improved filling of the device, for example, using a vial adapter and an automated filling station.

Tamper-Evident Enclosure for PICC Line
20230218859 · 2023-07-13 · ·

A catheter enclosure device for locking an intravenous catheter therein with tamper-evident features to deter unauthorized use. The catheter enclosure device may be particularly useful for peripherally inserted central catheters (PICC). The enclosure device comprises an open-top box and a removable lid for covering the box. The open-top box has a compartment for holding the proximal end of an intravenous catheter. The lid comprises a panel for covering the open portion of the open-top box and a folding wing that overhangs the forward end of the box when covering the box. The folding wing further comprises a retaining anchor. When the folding wing is folded down, the retaining anchor inserts into a locking slot on the forward end of the box, thereby preventing the lid from being removed off the box. Also disclosed are methods for using the catheter enclosure device.

Connector for aseptic transfer of fluid

A drug delivery system for injecting a medicament may include a housing defining a cavity, a container received within the cavity and configured to receive a medicament with the container including a closure, a valve assembly received within the cavity and including a piercing member configured to pierce the closure of the container, and a connector arrangement provided between the container and the valve assembly, the connector arrangement movable between a first, pre-use position maintaining sterility between the closure of the container and the valve assembly and a second, use position permitting fluid communication between the container and the valve assembly.
