An on-body injector system includes a drug container assembly including a container, a seal member, and a sealing interface between the seal member and the container. The container includes an opening and the seal member at least partially covers the opening in the container. A fluid pathway assembly is coupled to the drug container assembly and includes a needle that is movable between a storage position, in which a point of the needle is spaced from the seal member, and a delivery position, in which the point of the needle is disposed at least partially through the seal member. A radiation generator is configured to emit rays of radiation to sterilize and/or disinfect the sealing interface. A barrier is disposed adjacent to the sealing interface and has an opening. At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.

The present disclosure relates to the field of medical devices generally and specifically, to endoscopic systems and methods for resection of malignant and pre-malignant lesions within the gastrointestinal (GI) tract. In particular, the present disclosure relates to systems and methods for delivering injectable compositions between tissue layers (e.g., between the muscularis and submucosa layers) to elevate and stabilize the lesion for fast and efficient resection.

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a housing and a container disposed therein. The container may include a reservoir containing a drug and a movable stopper. A first seal member may be connected to the container at a distal end of the reservoir. A first removable membrane may cover an exterior surface of the first seal member to maintain sterility of that surface prior to operation of the device. A fluid pathway assembly may be configured to establish fluid communication with the reservoir during operation of the device. A second seal member may be connected to a first end of the fluid pathway assembly. A second removable membrane may cover an exterior surface of the second seal member to maintain sterility of that surface prior to operation of the device.

At least a portion of the drug container assembly is positioned adjacent to the opening in the barrier.

A drug delivery sterilization system includes a housing defining at least one receptacle, a container assembly having first and second ends, an elongated portion extending therebetween, and an electron beam or x-ray generator disposed near the housing. The container assembly includes a container having a container contact region at the second end and an inner volume to contain a medicament, a seal member having a seal member contact region to form a sealing interface with the container contact region, and a coupling device adapted to sealingly couple the seal member to the container. The container assembly is at least partially disposed in the receptacle such that the second end of the container is exposed through the housing. The electron beam or x-ray generator generates a sterilizing beam that penetrates the seal member to sterilize the sealing interface.

A medicament injection device comprising: a main body configured to receive a medicament cartridge, a needle sleeve axially movable with respect to the main body, a needle holder holding a needle, and a displacement element coupled to the needle holder and disengageably coupled to the needle sleeve; wherein, upon axial displacement of the needle sleeve by a predefined distance in a proximal direction, the needle carrier and needle are displaced axially in a proximal direction.

An assembly for a cartridge needle insertion mechanism includes a housing, a cartridge needle defining a cartridge needle axis and a cartridge closed by a septum. A cartridge needle slider is linearly guided by the housing along an insertion axis to be moved by a driver from a first position, where the cartridge needle is not penetrating the septum, to a second position where the cartridge needle penetrates the septum of the cartridge. A cartridge needle holder holding the cartridge needle is operatively coupled with the cartridge needle slider to be moved with the cartridge needle slider from the first to the second position. The assembly includes a compliant coupling between the cartridge needle holder and the cartridge needle slider configured to facilitate movement of the cartridge needle holder with respect to the slider when moved into the second position, thereby compensating for needle penetration forces.

The present disclosure relates to a administration assembly for a medicament delivery device, comprising: an elongated tubular delivery member cover (7), a cartridge holder (11) configured to be received by the delivery member cover (7) and configured to accommodate a medicament cartridge (31), the cartridge holder (11) having a radially flexible and radially inwards extending cartridge blocking protrusion (11b) configured to prevent the medicament cartridge (31) from moving proximally until being subjected to a proximally directed force larger than a threshold value, a needle assembly (13) comprising a double-edged needle having a proximally extending needle portion (13a) and a distally extending needle portion (13b), wherein the needle assembly (13) is configured to be assembled with the cartridge holder (11) so that the distally extending needle portion (13b) extends into the cartridge holder (11), and an administration mechanism including a plunger rod (27) configured to be proximally biased, wherein the delivery member cover (7) is configured to be linearly displaced in the distal direction relative to the cartridge holder (11), and wherein the delivery member cover (7) is configured to activate the administration mechanism when moved in the distal direction, causing the administration mechanism to move the cartridge holder (11) in the proximal direction and to subsequently move the plunger rod (27) in the proximal direction inside the cartridge holder (11) with a force larger than the threshold value.

A cartridge for dispensing a material, having: a sleeve having a longitudinal axis and a distal wall with a dispensing hole; a barrel defining a chamber for the material, including a proximal open end and a breakable distal wall at its distal end, and being movable in the sleeve between a first position where its distal wall is a distance from the sleeve's distal wall and a second position where its distal wall's sealing portion contacts an inner surface of the sleeve's distal wall; and a piston having a plate movable to seal the barrel's chamber. The sleeve includes an internal piercing element, near the dispensing hole, for breaking the barrel's distal wall upon moving the barrel from the first to the second position. Around the piercing element is an annular cavity delimited peripherally by a beveled inner surface that complements a beveled outer surface of the barrel.

The present invention relates to a drug injection cartridge and a drug injector comprising same, and has an anti-pushing part (100) formed between a needle part (10) and a cartridge (20), thereby preventing a rubber film from being expanded by pressure applied to the cartridge (20), such that a drug does not leak, and the accuracy of drug injection can be improved.
