The needle hub (40, 140) includes a proximal end (42, 142), a distal end (46, 146), a needle (41, 141) fixedly connected to the distal end of the needle hub (40, 140), and a plurality of ribs (54) or a cylinder (150) disposed between the proximal and distal ends. An actuation button movably received in a transverse opening of the needle shield (20, 120) to engage the needle shield (20, 120), the needle hub (40, 140) and a medical device. A spring (58, 158) is disposed between the needle hub (40, 140) and actuation member to automatically retract the needle (41, 141) into the needle shield (20, 120).

The present solution provides trans-round window membrane (RWM) drug delivery. As an overview, the system can include a micropump that is connected to a flexible cannula. The cannula can include a stiffened and sharpened tip to facilitate insertion through the RWM. The cannula can be inserted through the RWM to improve the distribution of the delivered drug throughout the inner ear. The present solution can function as a small implantable or wearable device that can be used for both chronic and acute trans-RWM drug delivery. With this configuration, the micropump can constantly or intermittently deliver, over a period of days to months, small volumes of drugs from an internal reservoir.

A medical device operable to deliver a fluid to a patient, including a base having a base body and a hollow cannula for insertion into a patient, the hollow cannula being one of fixed to the base and movable relative to the base to a patient insertion position. The base body includes a fluid pathway that is one of fluidly connected with the hollow cannula and fluidly connectable with the hollow cannula. The fluid pathway includes a pathway portion sealed with a sealer, and the pathway portion includes an adsorbent operable to modify a fluid traversing the pathway portion by removing one or more compounds or substances from the fluid prior to delivery of the fluid to the patient through the hollow cannula.

This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

Devices, systems, and methods are provided herein for delivering medication (e.g., insulin) via a wearable pump having a patch-style form factor for adhesion to a user’s body. The reusable pump may be coupled to a disposable cap housing a microdosing system for delivering precise, repeatable doses of medication to a cannula configured to deliver medication to a target infusion area beneath the user’s outer skin layer. The system further may include an applicator for inserting the cannula into the user’s skin and/or applying an adhesive pad to the skin.

A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

A tool for manipulating a catheter interface protection device includes a base, a first arm extending from the base, and a second arm extending from the base. The first arm includes an outwardly projecting first hook configured to engage a first vent of a catheter interface protection device. The second arm includes an outwardly projecting second hook configured to engage a second vent of the catheter interface protection device. A method of manipulating a catheter interface protection device includes positioning the base around the catheter interface protection device so that the first arm is on a first side of a slot of the catheter interface protection device and the second arm on a second side of the slot of the catheter interface protection device opposite the first side, and bending the catheter interface protection device from the slot towards and around the first hook to create an opening.

A patch for placement on the skin and for use with an injector device. The patch comprises a first layer on a first side of the patch, a second layer on a second side of the patch opposite to the first side, and a sealed fluid reservoir between the first and second layers. A fluid is contained within the fluid reservoir. The patch also includes a moveable rupturing element and an aperture. The rupturing element is configured to rupture the fluid reservoir to allow release of the fluid out of the fluid reservoir. The aperture extends at least partially through the patch to receive an injection needle of an injector device. Also provided is a system comprising an injector device and such a patch, and also a method of use of such a patch.

A fluid connector assembly. The fluid connector assembly includes a tab portion including a slot; a plug portion slidably connected to the tab portion the plug portion comprising a fluid path and a disc, the disc configured to seat within the slot; a catch feature located on a first end of the tab portion and configured to interact with a reservoir; and a latching feature located on a second end of the tab portion, the latching feature configured to interact and lock onto the reservoir, wherein force applied to the plug portion may overcome a threshold force and unseat the disc from the slot wherein the plug portion moves with respect to the tab portion.

A system for strain relieving intravenous (IV) assembly includes a dressing and an anchor portion for use with the dressing. In various embodiments, the dressing may cover an injection site into a portion of a patient's body for an intravenous (IV) assembly that provides fluid communication between the injection site and a fluid reservoir remote from the injection site through a flexible tube. In an illustrative example, the anchor portion may include a first member and a second member. The first member may be secured, for example, to the dressing and may, in some examples, wrap around the tubing so as to resist axial movement of the tubing relative to the dressing. The second member may be secured to the dressing and may wrap around the tubing and a portion of the patient's body so as to resist radial movement of the tubing relative to the body.
