International Classification:

A61M 25/00

Abstract:

A catheter adapter may include a distal end, a proximal end, an inner surface extending through the distal end and the proximal end and forming a lumen, and a side port forming a side port pathway through a sidewall of the catheter adapter and in fluid communication with the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to the side port pathway. The catheter assembly may include one or more features to facilitate flushing of the catheter assembly: a diameter of the side port may increase in a distal direction; a portion of the inner surface proximal to the catheter and distal to the septum may include multiple grooves; the side port pathway may include a non-cylindrical portion; an insert; a rotation element; and a pivot element.

International Classification:

A61M 39/10

Abstract:

A catheter adapter including a housing and an extension portion extending from the distal end of the housing and defining a passageway configured to receive a catheter. The first material of the housing is more flexible than the second material of the extension portion. The catheter adapter may further include a body contact portion comprising an upper surface corresponding to a surface of the housing and a lower surface defining an outer surface of the catheter adapter. The housing may include a body, an access port extending from the body, and a plurality of protrusions extending from the body and/or the access port. The body contact portion covers at least a portion of the housing, and the protrusions are embedded in and are completely surrounded by the body contact portion. The catheter adapter may further include a connection portion connecting the extension portion to the body contact portion.

International Classification:

A61M 25/06
A61M 25/00

Abstract:

A catheter assembly may include a catheter adapter, which may include a proximal end, a distal end, a lumen extending through the proximal end and the distal end, and a side port. The catheter assembly may include an extension set, which may include a first extension tube that may extend from the side port. The extension set may include a first connector, which may be coupled to a proximal end of the first extension tube. The first connector may include a first port and a second port. The extension set may also include a second extension tube. A distal end of the second extension tube may be coupled to the first port. The second extension tube may be longer than the first extension tube. The extension set may include a second connector, which may be coupled to the proximal end of the second extension tube.

International Classification:

A61M 25/06

Abstract:

An attachment for a catheter assembly may include a platform, which may include an upper surface and a bottom surface. The bottom surface may be configured to contact skin of a patient. At least a portion of the upper surface may be configured to support the catheter assembly. The upper surface may support the catheter assembly at an angle with respect to skin of the patient that is approximately equal to an insertion angle of a catheter of the catheter assembly. The attachment may include snap feature coupled to the upper surface of the platform. The attachment may include a blunt cannula extending distally from the snap feature. The blunt cannula and the portion of the upper surface may provide a generally straight pathway for an instrument inserted distally through the attachment into the catheter assembly.

Abstract:

An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.
