An apparatus to determine if a constituent member has been damaged. The constituent member can be a medical product comprising a coating, or a substance kneaded into the product, which emits a fluorescence in the near-infrared region. The apparatus to determine if this constituent member has been damaged includes an irradiation light source, an optical filter, an imaging unit, a display unit and a control unit connected to the light source, the optical filter and the imaging unit to determine and inform that damage has occurred in the constituent member.

A vascular access system may include a catheter assembly, which may include a catheter hub and a catheter extending distally from the catheter hub. The vascular access system may include an instrument advancement device coupled to the catheter assembly. The instrument advancement device may include a vascular access instrument. The vascular access instrument may include a coil formed by a flat wire wound around an axis into multiple loops. The instrument advancement device may be configured to advance the vascular access instrument from a retracted position to an advanced position beyond a distal end of the catheter. The distal end of the catheter may include a distal opening. The coil may extend through the distal opening of the catheter in response to the vascular access instrument being in the advanced position.

A drug mixing system including at least one receptacle port adaptor adapted to be inserted into a port of a fluid receptacle, at least one syringe adaptor adapted to be attached to a syringe and to the at least one receptacle port adaptor and at least one vial adaptor adapted for connection to a vial containing a drug and adapted for connection to the at least one syringe adaptor, the system being characterized in that at least one of the receptacle port adaptor, the at least one syringe adaptor and the at least one vial adaptor being vented to the atmosphere in a manner which prevents release to the atmosphere of possibly harmful contents of the vial in a liquid, solid or gaseous form.

A catheter assembly and/or an introducer may include one or more features configured to guide a probe and/or a catheter distally through a septum. The catheter assembly may include a catheter adapter and the septum. The catheter adapter may include a distal end, a proximal end, and a lumen extending therebetween. In some embodiments, the septum may be disposed within the lumen. The septum may include a proximal surface that is tapered inwardly in a distal direction such that the proximal surface of the septum is configured to guide the probe and/or the catheter distally through the septum. The catheter assembly may be configured to receive an introducer, which may include an introducer element. A proximal end of the introducer element may include another proximal surface that is tapered inwardly in the distal direction such that the other proximal surface is configured to guide the probe or the catheter distally through the septum.

Described are a system and method that utilize bioelectric signaling to balance electrical potentials in a subject's body via neuro-hormonal circuit loops, to increase elasticity of the subject's arteries to promote protein release to dampen arterial blood pressure, and to change arterial electrical charges to reduce narrowing of the arteries. The described system is designed to localize and stimulate the fibers inside the vagus nerve without inadvertent stimulation of non-baroreceptive fibers causing side effects like bradycardia and bradypnea. The system also controls release of specific proteins known to lower blood pressures including tropoelastin (known to increase elasticity in the aorta and other peripheral blood vessels).

A medical device includes: a first member including: a body portion, and an anchor, wherein a resin material of the anchor is different from a resin material of the body portion, and wherein the anchor is interlinked to the body portion; and a second member including a connecting portion that is connected to the anchor, wherein a resin material of the second member is the same as the resin material of the anchor.

A skin regeneration therapy combining precise bioelectric signals, light, and biologics for skin treatment and regeneration. Precise bioelectric signals give clear instructions to the stimulated cell DNA/RNA to produce specific regenerative proteins on demand. Bioelectric signals give clear instructions to cell membranes on what to let in and what to let out and serve as an equivalent or surrogate of environmental stimuli to cause a cell action in response.

An infusion or transfusion set for administering a liquid from a container using a pump. The infusion or transfusion set includes a branch that provides a fluid connection between a first supply line, a second supply line and a discharge line. The first supply line includes a liquid-retaining filter membrane having a breakdown pressure. At least the second supply line has a check valve. The check valve is opened for fluid passage in the direction towards the branch if the pressure difference at the check valve is greater than a threshold value that is less than the breakdown pressure of the liquid-retaining filter membrane.

A sheath valve housing including: an input port disposed on a proximal side of the sheath valve housing; an output port disposed on a distal side of the sheath valve housing, the input port and output port defining a longitudinal axis extending therethrough; a chamber disposed within the sheath valve housing between the input port and the output port and centered on the longitudinal axis, a catheter pathway being defined within the sheath valve housing through the chamber between the input port and the output port; and a plurality of ribs disposed about the chamber so that a member is aligned with the longitudinal axis upon insertion into the chamber.

PIVCs with extension sets can include one or more flow diverting features for maximizing the amount of flushing that occurs within the interior of the catheter adapter. These flow diverting features can therefore minimize the amount of residual blood, medicament, or other fluid that may exist within the catheter adapter after the PIVC has been flushed via the extension set. The flow diverting features may be in the form of structural modifications to the side port of the extension set, separate components that are contained within the side port or catheter adapter, integrated components within the side port or catheter adapter, other features or some combination of any of these features.
