Needle assemblies, such as catheter devices, and related methods having a needle hub with a needle, a catheter tube with a catheter hub and having the needle extending through the catheter tube. A valve is positioned in an interior cavity of the catheter hub and a valve actuator having an extension leg with an engagement section for supporting an arm of a needle safety clip when the safety clip is located in the interior cavity of the catheter hub.

Needle assemblies are generally discussed herein with particular discussions extended to needle assemblies having a tip protector with a plurality of wall surfaces for preventing contact with the needle tip from a side. Aspects of the tip protectors discussed herein include a first protector body having an arm for blocking a needle tip surrounded by a second protector body having a plurality of wall surfaces.

In a safety apparatus for medical needles, when leg portions are extended from a first folded position to a second extended position, a distal end of a needle is introduced into a space of a shield member connection hub, and a first blocking wall and a second blocking wall overlap so as to block the cross section of the space to form a double blocking wall and blocks the cross section of the space. The double blocking wall is capable of preventing the distal end of the needle from moving downward from the double blocking wall and preventing the distal end of the needle from being exposed to the outside of the apparatus.

The invention relates to a needle safety device for a medical device, the needle safety device comprising: a base portion having a bore extending along a longitudinal center axis therethrough for receiving a needle; and two opposing jaws extending from the base portion generally in the axial direction and each having a head portion in the region of its free end, wherein the needle safety device includes a locking projection for securing the needle safety device to the medical device. The needle safety device according to the invention further provides at least one elastic element mounted to the jaws in a non-surrounding manner lateral to the center axis in a region between the base portion and the head portions, wherein at least one elastic element and the jaws are configured such that the jaws can be spread apart against a restoring force of at least one elastic element in order to allow the needle received in the bore to extend all the way through the needle safety device.

A septum for sealably covering a fluid cavity defined in an implantable device, which may be an access port, and methods for assembling the implantable device. The septum may include a resilient septum body, an annular flange extending radially outward from the septum body, and a reinforcement component disposed in the annular flange for reinforcing engagement with a corresponding annular groove defined in a body of the implantable device. The reinforcement component may inhibit unintended detachment of the septum from the implantable device.

A safety needle set for delivering fluid to an access port, the safety needle set having insertion and safety configurations. The safety needle set includes a needle assembly and a base assembly. The needle assembly includes a needle having a distal end with a non-coring tip, the distal end angled with respect to a proximal end of the needle. The needle assembly also includes a pair of foldable wings coupled to the needle, including a first wing and a second wing. The first wing may have a recess, and the second wing may have a protrusion, such that when the first wing contacts the second wing in a wing folded configuration, the recess receives the protrusion. The base assembly includes a housing, a safety needle assembly at least partially disposed in an interior of the housing, and an interface pad coupled to a bottom surface of the housing.

A catheter assembly including a catheter carried by a catheter adapter, a needle having a sharp distal tip and disposed in the catheter such that in a first needle position, the needle extending beyond the catheter, a septum actuator having openings, the septum actuator disposed in the catheter adapter and configured to pierce a septum, and a spring clip disposed in the septum actuator and engaging the openings of the septum actuator in the first needle position.

A catheter assembly (10) comprises a catheter (22), a needle (12) having a sharp distal tip disposed in the catheter (22), a catheter hub (14) housing the catheter (22) and the needle (12), the catheter hub (14) having a collar (34) including a notch (36), a needle shield (20) connected to the catheter hub (14) when the needle (12) is in a first position, and a clip (40) disposed in the needle shield (20) that cooperates with the needle (12), wherein the clip (40) engages the catheter hub (14) in the first position of the needle (12), and the clip (40) disengages the catheter hub (14) via the notch (36) when the needle (12) is retracted to a second position to enclose at least a portion of the needle (12). The clip (40) is mounted in the outer housing (38) of the needle shield (20) via a spade (66) having an outer wall (70) exposed to the outside of the needle shield (20), in order to reduce the overall width of the needle shield (20).

A catheter system may include a needle assembly coupled to a catheter adapter. The needle assembly may include a housing, an introducer needle, a proximal opening, a distal opening, and a needle tip shield feature. A distal tip of the introducer needle may be configured to be proximally withdrawn from a first position to a second position in which a bump feature of the introducer needle contacts and is prevented from moving through the proximal opening. In response to withdrawal of the distal tip proximally from the second position to a third position, the housing may move proximally, and the needle tip shield feature may be released to block the distal opening. The needle tip shield feature may not contact the introducer needle when the distal tip moves proximally from the first position to the second position and from the second position to the third position.

A method of treating a patient using a power-injectable access port, including implanting the power-injectable access port in the patient, imaging the power-injectable access port following implanting, and power injecting a fluid into the patient through the power-injectable access port. The power-injectable access port includes a septum covering a reservoir, the septum including a radiopaque material forming at least one letter, the at least one letter indicating that the power-injectable access port is suitable for power injection. The power-injectable access port is designed to accommodate a pressure developed within the reservoir of at least 35 psi, and a fluid flow rate of at least 1 milliliter per second. Imaging the power-injectable access port produces an image, and the method includes identifying the at least one letter on the image to confirm that the power-injectable access port is suitable for power injecting a fluid.
