A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator is positioned to extend proximally in the interior cavity and support a seal member positioned thereon in the interior cavity. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. The seal member may be configured for multi-use and include a biasing member that moves the seal member to force the membrane back over the actuator to close the membrane.

Catheter assembly with seal member

A method of creating a feature on a needle. The method comprising the steps of providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter; gripping a distal portion of the needle about the outer diameter; gripping a proximal portion of the needle about an outer diameter; and applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.

Cannula bump

A method of constructing a catheter assembly having an integrated septum. The method comprising molding a catheter hub having a distal end, a proximal end, and an internal wall defining an internal fluid passageway therebetween, the internal fluid wall defining an injection mold window located between the distal end and the proximal end; seating a catheter tube within the internal fluid passageway of the catheter hub, such that a proximal end of the catheter tube resides within the internal fluid passageway of the catheter hub, and a distal end of the catheter tube extends distally from the distal end of the catheter hub; plugging at least a proximal end of the catheter hub with a mold core shut off pin; and injection molding a septum in at least a portion of the internal fluid passageway between the mold core shut off pin and the proximal end of the catheter tube through the injection mold window.

Overmolded septum for catheter hub

An intravenous catheter assembly that includes a catheter tube and an introducer needle that is disposed, at least in part, within the catheter tube when the introducer needle is in a ready for use position. The introducer needle includes a lateral surface that defines a relief that is positioned under the distal end of the catheter tube when the introducer is in the ready for use position to provide a flow path into a flash indication space.

IV catheter with vein entry indication

A needle assembly. The needle assembly enabling the analysis of fluid trapped in a flashback chamber after an insertion needle has been inserted into a patient's vein.

Needle assembly with diagnostic analysis provisions

A catheter hub assembly. The catheter hub assembly includes a catheter hub body, a septum and a septum retainer, the catheter hub body having a distal end, a proximal and an internal wall defining an internal fluid passageway therebetween, the internal wall defining a transitional step within the internal fluid passageway, the septum positioned within the internal fluid passageway such that a distal end of the septum abuts up against the transitional step, the septum retainer at least partially receivable within the internal fluid passageway and having an outer wall shaped and sized to interlock with the inner wall of the catheter hub body, the outer wall including one or more lateral ribs configured to inhibit rotation of the septum retainer relative to the catheter hub body.

Closed system catheter

A safety catheter insertion assembly including a catheter hub coupling assembly. The safety catheter insertion assembly having a needle hub slideably coupled to a needle housing such that the needle hub is moveable between a first position wherein an insertion needle extends from the needle housing, and a second position wherein the sharp distal tip is housed within the needle housing, the catheter hub coupling assembly coupling the catheter hub to the needle housing in the first position and releasing the catheter hub from the needle housing in the second position.

Releaseable catheter hub retainer

Method of making catheter assembly with seal member

A catheter assembly includes a catheter hub defining an interior cavity and a catheter tube extending distally thereof. A rigid actuator extends proximally in the interior cavity and supports a seal member thereon. The seal member includes a central membrane, a distal portion, and a proximal portion. An hourglass shaped actuator cavity is formed in the distal portion and receives a barbed end of the actuator. The outer surface of the seal member is in partial circumferential engagement with the catheter hub to define an air path that allows fluid communication between areas of the interior cavity distal and proximal of the seal member. A punch tool is provided to form a tri-slit in the membrane of the seal member.

A needle tip spring protector for a needle having a proximal end, a distal end, and a shaft extending therebetween. The needle tip spring protector includes a spring that circumferentially surrounds a portion of the needle shaft and is restrained in a state wherein its inner diameter is large enough to allow the shaft to move freely within the spring. When the needle is moved to a position in which its distal end is at least partly within the spring, at least one of the ends of the spring releases from restraint such that the spring automatically returns to a state in which its inner diameter is sized so as to grippingly engage the shaft of the needle. Thus, after activation, the spring securely surrounds the distal end of the needle to protect healthcare workers and others from accidental contact with the needle's distal end. When used in conjunction with a catheter assembly, the needle tip spring protector may passively release from the catheter hub after the spring is automatically activated.
