A set of at least two drug delivery devices includes a first drug delivery device and a second drug delivery device, The first and second drug delivery devices each include a first set of mutual members that are identical, and the first drug delivery device and the second drug delivery device each include a second set of distinguishing members that differ. The first drug delivery device includes a first connection device for attaching a first dispensing unit to the first drug delivery device and the second drug delivery device includes second connection device for attaching a second dispensing unit to the second drug delivery device, the first and second connection devices differ from each other so that the second dispensing unit is not attachable to the first connection device and the first dispensing unit is not attachable to the second connection device.

The invention relates to a method for reducing an amount of sub visible particles in a pharmaceutical composition contained in a medical injection device comprising a container (1) including a barrel (10) lubricated with a lubricant coating (2) in contact with the pharmaceutical composition, and a stopper (14) in sliding engagement within the barrel (10), the container comprising a region (130, 121, 123) extending distally from the distal end (100) of the barrel which is not accessible to the stopper. During formation of said lubricant coating (2) on the inner wall of the barrel, the method comprises limiting lubricant from being deposited into said region (130, 121, 123) extending distally from the distal end (100) of the barrel.

The present invention relates to a stopper for an injector for delivery of a pharmaceutical composition and to an injector with the stopper. The stopper has a stopper body with an actuating surface opposite an outlet surface, an axial length between the actuating surface and the outlet surface, and a transverse diameter, which stopper body defines an access diameter, the stopper at an axial location from the actuating surface comprising a deformable sealing element surrounding the stopper body and having an outer diameter, which is larger than the transverse diameter, which deformable sealing element is made from a thermoplastic elastomer and has an axial extension in the range of 5% and 95% of the axial length of the stopper body, and the stopper comprising a cavity at the axial location of the deformable sealing element, the cavity having a lateral extension larger than the access diameter of the stopper body.

An auto injector apparatus includes a syringe and an auto injector. The syringe includes a barrel holding a therapeutic fluid including an anti-calcitonin gene-related peptide (anti-CGRP) antibody. The syringe also includes a stopper disposed within the barrel and the stopper moves axially within the barrel between a first position and a second position to expel at least some of the therapeutic fluid from the syringe. The auto injector includes a rod that abuts the stopper and an injection spring that drives the rod to apply a dispensing force through the rod to the stopper. The dispensing force includes a first dispensing force of between 20 N and 40 N and a second dispensing force of between 12 N and 20 N. The injection spring initially applies the first dispensing force and then applies the second dispensing force to move the stopper to the second position.

A liquid formulation of an ophthalmic drug in a pharmaceutical package, for example a syringe, cartridge, or vial, made in part or in whole of a thermoplastic polymer, coated on the interior with a tie coating or layer, a barrier coating or layer, a pH protective coating or layer, and optionally a lubricity coating or layer.

A patient interface includes a seal forming portion, a pad, and a cushion. The seal forming portion may have a base surface and a plurality of fibers fixed to and extending away from the base surface for contacting a patient's skin. The cushion may have at least along a portion of the circumference a first structure having an elongate section joined with at least one end section oriented substantially perpendicular or at an angle to the elongate section. A first end A of the elongate section may be connected or connectable to a frame member. The end section may be provided at an opposing second end B of the elongate section. The pad may have a resilient foam material layer with the seal forming portion. The pad may be adapted to be connected to the cushion.

An infusion system comprises an infusion set (30) with one or more advanced features including tube set strain relief (10), infusion pumps having heat exchange abilities and two-direction pumping abilities (100), Piezo pump devices (200), reservoirs (220, 240) made from expanded tubing, and oil impregnated pump plungers (302). An exemplary strain relief (10) includes an adhesive layer (12) such as pressure sensitive adhesive (PSA) secured to a base (14). The base (14) rotatably receives a pin (18) of a tube holder (16). The pin (18) is captured within an opening (22) of the base (14) to allow 360 degree rotation of the tube holder (16).

A patient interface comprises a cushion assembly including a textile membrane. The textile membrane includes an air impermeable silicone layer applied to a textile material. The textile material comprises 1) nylon and/or polyester, and 2) elastane. A yarn count of the nylon and/or polyester is in a range of 20-80 denier, and the textile material has stretchability in both a direction of the wales and a direction of the course.

A percutaneous circulatory support device includes a housing, a cannula coupled to the housing, the cannula having a first portion and a second portion, and wherein the cannula includes at least one slot disposed along at least the first portion of the cannula, the at least one slot configured such that the first portion of the cannula is defined by a first stiffness and a second portion of the cannula is defined by a second stiffness, the first stiffness being different than the second stiffness.

The present disclosure provides a guide wire system comprising (a) a guide wire having a distal end and a proximal end, wherein the guide wire comprises a superelastic material, (b) a first connector coupled to the proximal end of the guide wire, (c) a second connector coupled to the guide wire between the distal end and the proximal end, (d) an electromagnetic sensor coupled to the distal end of the guide wire, and (e) a polymeric tube surrounding the guide wire and at least a portion of the electromagnetic sensor.
