An actuation device includes a lancing device held by and moveable relative to a distal end portion of a housing. A drive member is supported by the housing and arranged to engage the lancing device to move the lancing device in the first direction from a retracted position to an extended position upon movement of the drive member in a first direction. A piercing member of the lancing device is arranged to extend from the distal end portion of the housing by a first distance when the lancing device is moved to the extended position, the first distance being adjustable by adjusting the retracted position of the lancing device relative to the distal end portion of the housing.

Insertion device systems and methods

A therapeutic agent injection device including an injection device for delivering a therapeutic agent to a patient having a body, the body having a patient face and a port face opposite the patient face, the port face having an introducer port including an introducer channel and an injection port including an injection channel, the introducer channel being in fluid communication with the injection channel through a cross channel, the injection channel defining an injection axis; a delivery tube for subcutaneous delivery of the therapeutic agent to the patient, the delivery tube projecting from and being generally perpendicular to the patient face, the delivery tube defining an introducer axis and being in fluid communication with the injection port; and a patch, the patch being attached to the patient face and being operable to adhesively attach to the patient; wherein the injection axis is parallel to the introducer axis.

Therapeutic agent injection device

An insertion device may include a device housing configured to be operatively engaged with and disengaged from a base, and engageable with an actuation device, the device housing having a carrier body supporting a piercing member. The carrier body moveable by a carrier body of the actuation device at least between a retracted position and an advanced position. The device housing having a section for supporting a portion of the carrier body of the device housing, the section moveable relative to the carrier body of the device housing to provide sufficient clearance to allow the carrier body of the device housing to be moved by the carrier body of the actuation device.

An automated reservoir filling system for a portable medical device is disclosed. The system includes a vial sealed by a septum partially filled with a liquid and a gas occupying a headspace. The system further includes a reservoir with a volume defined between a reservoir septum and a plunger head. The plunger head is coupled to a plunger arm which is further coupled to a drive system. Further included is a transfer system with a vial end that pierces the vial septum and remains in contact with the liquid, and a reservoir end that pierces the reservoir septum and remains in the reservoir volume. A controller coupled to the drive system to actuates the drive system automatically drawing fluid from the vial to the reservoir through the degas system.

Automated reservoir fill system

A fluid infusion device, for delivery of a medication fluid to the body of a user, includes a housing, a fluid reservoir for the medication fluid, a dosing mechanism, an infusion component, and a mechanical actuator. The fluid reservoir and the dosing mechanism are located in the housing, and the dosing mechanism is coupled to receive the medication fluid from the fluid reservoir. The dosing mechanism has an adjustable fluid chamber that defines a variable dosage volume. The infusion component is coupled to the dosing mechanism to receive the medication fluid from the adjustable fluid chamber. The mechanical actuator is coupled to the dosing mechanism such that operation of the mechanical actuator causes the medication fluid to be expelled from the adjustable fluid chamber to the infusion component.

Mechanically actuated fluid infusion device

An on-body injector and method of use including an on-body injector for use with an injection device. The on-body injector includes a bolus reservoir; a bolus injection needle in fluid communication with the bolus reservoir, the bolus injection needle having a bolus injection needle tip aligned with the injection port, the bolus injection needle being slideably biased away from the injection port to define a gap between the bolus injection needle tip and the injection port; and a button operably connected to the bolus injection needle to slide the bolus injection needle along the injection axis. The button is operable to advance the bolus injection needle tip to close the gap and advance the bolus injection needle tip into the injection port. The button is further operable to advance a plunger through the bolus reservoir to deliver a predetermined bolus volume to the patient through the injection flow path.

On-body injector and method of use

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

A reservoir may be filled with fluidic media in a first type of environment, a plunger head may be placed within the reservoir in the first type of environment, and a casing that may be configured to envelop at least a portion of a plunger arm operatively connected to the plunger head may be attached adjacent to at least a portion of the reservoir in a second type of environment. A reservoir may be provided having a first and second portion for respectively containing fluidic media, the second portion may be adapted to be removable, the reservoir may be selectively filled with a first volume or a second volume of fluidic media, a seal member may be placed in the reservoir, and the second portion may be removed in a case where the reservoir contains the first volume of fluidic media.

Reservoir filling systems and methods

A piercing member for piercing a membrane may be arranged within a housing and supported by a compliant that may be for allowing articulation of the piercing member relative to the housing in a case where the piercing member is in the membrane and moved relative to the housing.

A casing may be configured to envelop at least a portion of a plunger arm attached to a plunger head located in a reservoir. A plunger head moveable in a reservoir may have a front portion comprising a first material compatible with fluidic media in an interior volume of the reservoir. A seal member having a first end and a second end that taper to a mid-portion may be positioned between a reservoir and a plunger head. A bias member may be configured to force a plunger arm operatively connected to a plunger head against a drive member to operatively engage the plunger arm to the drive member. A plunger head moveable in a reservoir may have a first ridge, a second ridge, a seal member adjacent at least one of the ridges, and protrusions arranged around at least one of the ridges.
