Various embodiments of the present invention are directed to patches for medical devices. In various embodiments, an adhesive patch of a medical device may have selective areas with adhesive material of varying adhesion strengths. In other embodiments, an adhesive patch of a medical device may include adhesive material that may be activated by a catalyst to increase or decrease the adhesion strength of the adhesive material. In further embodiments, a medical device may include a pierceable membrane containing an agent, the pierceable membrane positioned to be pierced by a needle and to cause some of the agent to be carried to the user-patient.

Adhesive patch systems and methods

An insertion device, generally used with an infusion set, including a needle being adapted for puncturing at one end and including at the opposite end a hub. The hub includes a handle part and a guard part that are capable of securing the needle through the use of locks. Locking structures are used to secure the insertion device in a position where the needle is covered in a locked position, avoiding unintended contact with the needle.

Insertion device

At least one tab may extend through at least one opening in a retaining member configured to cover at least a portion of a head of a reservoir body and a portion of a septum supported by the head of the reservoir body. A retaining member may be configured to cover at least a portion of a first head of a reservoir body and a portion of a septum supported by the first head of the reservoir body, and the reservoir body may have a second head having at least one tab. A retaining member located in a head of a reservoir body may be for retaining a septum on the head of the reservoir body, and the head of the reservoir body may have at least one tab.

Reservoir seal retainer systems and methods

A delivery device includes a durable housing portion and a separable disposable portion that selectively engage and disengage from each other. The disposable housing portion secures to the patient-user and may be disposed of after it has been in use for a prescribed period. Components that normally come into contact with a patient-user or with infusion medium are supported by the disposable housing portion, while the durable housing portion supports other components such as electronics and a drive device. A reservoir is supported by the disposable housing portion and has a moveable plunger that operatively couples to the drive device, when the disposable and durable housing portions are engaged.

Infusion medium delivery device and method with drive device for driving plunger in reservoir

An infusion medium delivery system, device and method for delivering an infusion medium to a patient-user, includes a needle inserter device and method for inserting a needle and/or cannula into a patient-user to convey the infusion medium to the patient-user. The needle inserter device and method operate to insert a needle and cannula into a patient-user's skin and automatically withdraw the needle from the patient-user, leaving the cannula in place and in fluid flow communication with a reservoir. The delivery device may include a base portion and a durable portion connectable to the base portion, and wherein the base portion can be separated from the durable portion and disposed of after one or more specified number of uses. The base portion supports the reservoir and the needle inserter device, while the durable portion supports a drive device for selectively driving the infusion medium out of the reservoir and into the needle and/or cannula.

Infusion medium delivery system, device and method with needle inserter and needle inserter device and method

A delivery device includes first and second housing portions that selectively engage and disengage. A reservoir on one housing portion operatively engages a drive device and/or a needle inserting device on the other housing portion. Upon proper engagement of the housing portions, the reservoir operatively couples to the drive device and/or the needle inserting device. A first magnet on the first housing portion and a second magnet (or a magnetically-attractive material) on the second housing portion are positioned to magnetically interact with each other, upon operative engagement of the housing portions. A third magnet on the second housing portion may be opposed to the first magnet to help align the housing portions for connection. A magnet-responsive device may be on one or both housing portions to detect alignment and/or connection of the housing portions.

Systems and methods allow for limiting a presence of air bubbles in a fluidic medium filled into a reservoir. A fluidic medium may be forced from a vial into a reservoir. A vial may be degassed prior to being used to fill a reservoir. A filling process may be automated and a membrane may be located in a fluid flow path to trap air bubbles in a fluidic medium being filled into a reservoir.

Systems and methods for reservoir filling

Various embodiments of the present invention are directed to limiting a presence of air bubbles in fluidic media in a reservoir. Air passages may allow air to escape from fluidic media in a reservoir. Membranes may allow for trapping air bubbles in fluidic media before fluidic media enters a reservoir. A membrane may allow air to flow from a first reservoir containing fluidic media to a second reservoir while plunger heads within each of the reservoirs are moved within the reservoirs. An inner reservoir with a membrane may be moveable within an outer reservoir to allow air to move from the outer reservoir to the inner reservoir. An inner reservoir containing pressurized gas may allow fluidic media to be transferred to an outer reservoir.
