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 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

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 housing may have a needle, plunger, and bias mechanism supported within the housing by a tab configured to retain the plunger in position and to allow the plunger to move under bias force imparted by the bias mechanism to move the needle to an insert position when the tab is removed. A base and a structure may be configured for relative movement there between and may be adapted to be secured to a user with a cannula extending through a body of the structure into the user during use of a medical device. A housing may be adapted to be secured to a user to support a medical device operable with an insertion needle, the housing having a magnifying material for increasing visibility of an injection site.

Needle insertion systems and methods

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.

Reservoir plunger head systems and methods

A plunger head moveable in an axial direction within a reservoir having an interior volume for containing fluidic media may have a first portion in contact with fluidic media when fluidic media is in the interior volume of the reservoir, the first portion comprising a first material compatible with fluidic media in the interior volume of the reservoir, a second portion located on an opposite side of the plunger head from the interior volume of the reservoir, the second portion connectable to a plunger arm, and a third portion located between the first portion and the second portion of the plunger head, at least one of the first portion, second portion, and the third portion is made of a material that comprises one of a cyclic olefin copolymer and a cyclic olefin polymer.

A system for retaining a fluid delivery device, the fluid delivery device may include a reservoir and a plunger arm operatively connected to a plunger head arranged for movement within the reservoir, the plunger arm having an arm portion operatively engageable with a drive member configured to move the plunger arm and the plunger head when the plunger arm and the plunger head are connected to the drive member. The system may include a rigid member arranged for movement and a bias member configured to urge the rigid member toward the plunger arm to force the plunger arm against the drive member to operatively engage the plunger arm to the drive member.
