An insertion assembly and method of manufacturing an insertion assembly. The method includes forming a catheter assembly including a catheter hub and a catheter, inserting a needle into the catheter assembly such that a distal tip of the needle extends distal of a distal end of the catheter, and permanently adhering an interface pad to the catheter hub. The interface pad can include a foam material including a haemostatic agent. The haemostatic agent can include microdispersed oxidized cellulose. The foam material can further include an antimicrobial agent such as chlorhexidine gluconate.

A safety needle having a rigid outer structure within which there is a cannula holding element of being movably coupled to an injector pen for a drug is provided. The cannula holding element supports a cannula having a first extremity and a second extremity for administration of the drug. A moving protective element associated with the rigid structure, covers the second extremity of the cannula after administration, with provision being made for a deforming member capable of deforming the cannula after administration of the drug so that the second extremity of the cannula remains within the protective element. The deforming member is associated with the protective element and is capable of rotating autonomously with respect thereto after administration of the drug to deform the cannula.

Needle shielding systems are disclosed. The needle shielding system comprises a needle, a cover sleeve, and a needle shield. The needle has a needle tip and a needle bulge spaced apart from the needle tip. The cover sleeve is slidably mounted over the needle and comprises an end portion having an internal diameter smaller than the width of the needle bulge, and a cover sleeve shaft extending from the end portion towards the needle tip and having an internal diameter larger than the width of the needle bulge. The needle shield comprises a base plate slidably mounted over the needle adjacent to the end portion, and at least one resilient arm extending from the base plate towards the needle tip. In use the needle shield and cover sleeve move along the needle until the end portion contacts the needle bulge and the cover sleeve shaft and the arm cover the needle tip.

A method of using a power-injectable port includes obtaining the power-injectable access port, attaching a catheter to an outlet stem of the power-injectable access port, and implanting the power-injectable access port and the catheter into a patient. The method further includes identifying the power-injectable access port following the implanting, inserting a distal end of a needle through the septum and into the reservoir, and injecting contrast media through the needle at a rate of at least one milliliter per second. The power-injectable access port includes a housing, a septum, a reservoir, and an outlet stem in fluid communication with the reservoir. The power-injectable access port is rated for injection of contrast media at a flow rate of at least 1 milliliter per second. The power-injectable access port is structured for operation at a pressure in the reservoir of at least 35 psi.

A method of performing a power injection procedure, including taking an x-ray of a subcutaneously implanted access port in a patient to determine whether the access port includes a radiographic feature indicating that the access port is suitable for flowing fluid at a rate of at least about 1 milliliter per second through the access port. The access port defines one or more fluid reservoirs, each fluid reservoir accessible through a cannula-penetrable septum. The method further includes identifying the indicating radiographic feature on the x-ray, and in accordance with the presence of the indicating feature on the x-ray, flowing a fluid through the access port at a rate of at least about 1 milliliter per second.

Devices for protecting a user from a sharp tip of a medical needle includes a central body portion, a medical needle having a sharp tip, a pair of wings in attachment to the central body portion. The medical needle includes a longitudinal axis that is substantially perpendicular to at least one of a long axis of the central body portion and the delivery tube. The pair of wings are selectively positionable in a first position in which the pair of wings are spaced apart from the medical needle and a second position in which the pair of wings are proximate the medical needle. A mechanical fastener is disposed on at least one of the pair of wings, the mechanical fastener configured to selectively attach the pair of wings together in the second position with the medical needle positioned therebetween. Methods of using the device including administering medicinal fluids.

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 first guide path, a second guide path and a third guide path may be disposed on the 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 retractable sheath also may have a guide element. The first, second and third guide paths are configured to slidingly receive the guide element. The device also having a first locking member, a second locking member, a rotating cam disposed in the housing body, 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.

An arterial syringe assembly is disclosed. The assembly includes a housing with a proximal end that may couple with a syringe barrel and a distal end that may couple with a needle. A needle cover is coupled with the housing at a hinge that may rotate to position the needle cover relative to the needle and may rotate to an orientation aligned with the needle such that the needle is within the needle cover. A needle plug is coupled to the needle cover at a distal end of the needle cover and may include plug material. The needle plug may slide axially relative to the needle to advance the needle plug at a distal end of the needle. A hydrophobic filter is positioned within the syringe barrel to evacuate air through a proximal end of the syringe barrel after the needle tip extends within the plug material.

A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. 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 needle guard.
