According to various embodiments, a method and system to obtain access to a blood vessel underneath a skin layer that may preserve lifespan of the blood vessel and reduce executional skill variability may be provided. The method includes placing a guiding portion between the blood vessel and the skin layer; and configuring the guiding portion to receive and guide a needle to reach the same location of the blood vessel repeatedly and consistently; and forming a resultant scarred track between the blood vessel and the skin layer as the guiding portion is resorbed over time. The system includes a vascular access device configurable to first possess strength to penetrate through a tissue layer, subsequently possess flexibility to conform to the surrounding tissue beneath the tissue layer; and a guiding portion which may be resorbable, wherein the inlet includes a larger diameter compared to the outlet.

A catheter assembly includes a flexible catheter (22), a needle (12) having a sharp distal tip, the needle (12) disposed in the flexible catheter (22) and moving from a first position that exposes the needle (12) to a second position, an outer member (26) that is configured to engage and disengage a catheter hub (14), an inner member (28) disposed in the outer member (26), and a needle protection (30) member disposed in the inner member (28), the needle protection member (30) enclosing at least a portion of the needle (12) when the needle (12) is in the second position.

Safety needle assemblies that include a needle having a sharp distal tip and a needle tip cover mounted on the needle are disclosed. The needle tip cover includes a proximal wall having an opening for the needle to pass therethrough. The needle tip cover urges against the needle in a ready to use position and shields the sharp distal tip in the secured position. The needle tip cover is moved proximally by a biasing member after the needle has been inserted into a patient a predetermined depth.

The present disclosure provides a cap assembly (1) for a medicament delivery device (6), the cap assembly comprising a tubular body (4) and a first lid (2), wherein the tubular body (4) comprises a proximal opening (7) for receiving a proximal part of a medicament delivery device, wherein the tubular body (4) is expandable in a longitudinal direction; and wherein the cap assembly is configured to change shape from a first, not expanded, configuration for protecting a medicament delivery member of the medicament delivery device prior to use to a second, expanded, configuration for storing the medicament delivery device (6) after use.

A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.

A power-injectable access port suitable for providing subcutaneous access to a patient and suitable for power injection. The access port includes a septum, a housing, and a reservoir defined by the septum and the housing. The septum may include a material that seals passages formed by puncturing the septum with a hollow slender element or another suitable access mechanism, and a radiopaque material forming a selected pattern when an x-ray is taken through the septum for identifying the power-injectable access port as being suitable for power injection. The housing and the septum may be structured for accommodating a pressure developed within the reservoir of at least 35 psi. The power-injectable access port may be designed to accommodate a flow rate of at least 1 milliliter per second of a fluid.

The invention relates to a safety needle device, particularly for the puncture of a port implanted subcutaneously in a human or animal body, comprising a first housing; a hollow needle, wherein the needle has a first sub-section and a second sub-section, and the first sub-section extends along a puncture axis, which runs at a right angle to the surface of the human or animal body, and the second sub-section of the needle being arranged at a right angle to the first sub-section, substantially parallel to the surface of the human or animal body, wherein the hollow needle is or can be connected to the first housing, particularly in the region of the second sub-section; a cover comprising a through-hole for receiving the first sub-section of the needle, wherein the cover can be moved from a first position into a second position relative to the first housing, wherein the movement occurs substantially along the puncture axis; and an at least partially flexible limiting element for limiting the relative movement between the first housing and the cover in the second position; wherein the device is characterized in that the cover has, on the surface facing away from the human or animal body, a guide sleeve for the first sub-section of the needle.

Drug delivery safety devices having trigger activation systems activated by pressure against the skin of a patient and which automatically shield the needle after withdrawing the needle from the skin of the patient.

A safety needle device is disclosed having a housing configured to couple to a syringe, the housing having a proximal end, a distal end, and a housing body. A needle hub is disposed on the proximal end of the housing and a needle cannula is attached to the needle hub. The device having a retractable sheath configured to move between an initial position, a retracted position and an extended position with respect to the housing, wherein the initial position partially exposes a distal tip of the needle cannula, the retracted position fully exposes the needle cannula, and the extended position fully covers the distal tip of the needle cannula. The safety needle device may include an activation latch, a lockout latch, a tether and a spring element to bias the retractable sheath to an extended state to cover the distal end of the needle cannula upon completion of an injection. The safety needle device may include a slider element disposed above an activation latch. A method of drug delivery is also disclosed.

A needle guard assembly having a resilient arm extending from a base. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being retracted into the elongate containment member.
