    摘要： A syringe assembly and methods of producing the syringe assembly are described. The syringe assembly may include a syringe body, a plunger rod, a barrel cover, and a tamper evident device. The syringe body has a chamber configured to receive a material. The plunger rod moves within the chamber to dispense the material. The barrel cover covers the syringe body. The backstop is attached to the barrel cover to prevent a portion of the plunger rod from moving proximally through the backstop. The tamper evident device includes a tamper evident cap covering a distal portion of the syringe body, a collar attached to the barrel cover, and a frangible connection between the tamper evident cap and the collar.

    摘要： In some examples, a catheter includes an elongated body that includes an inner liner, and outer jacket, and a structural support member positioned between at least a portion of the inner liner and the outer jacket. The outer jacket includes a plurality of outer jacket segments in which each outer jacket segment of the plurality is longitudinally adjacent to another outer jacket segment of the plurality. The structural support member includes a first section having a first density, a second section distal to the first section and having a second density, and a third section distal to the second section and having a third density, such that the second density being higher than the first and third densities. The second section of the structural support member is longitudinally aligned with a junction between two outer jacket segments of the plurality of outer jacket segments.

    摘要： A drug delivery device may include a housing defining a longitudinal axis and having an opening and a drug storage container including a barrel, a stopper and a delivery member, the stopper movably positioned within the barrel and the delivery member positioned at a distal end of the barrel and having an insertion end configured to extend at least partially through the opening during a delivery state. The device may also include plunger moveable toward the distal end of the drug storage container to engage the stopper and expel a drug from the drug storage container through the delivery member, the plunger including a body portion and a shock absorbing portion. The device may further include a plunger biasing member coupled with the plunger and configured to urge the plunger toward the distal end of the drug storage container.
