SYSTEMS AND METHODS TO IMPROVE INSTRUMENT GUIDANCE WITHIN AN INTRAVENOUS CATHETER ASSEMBLY

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.

CATHETER STABILIZATION PLATFORM, SYSTEMS, AND METHODS

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.

Closed IV access device with paddle grip needle hub and flash chamber

An IV access device can include a needle hub that incorporates a flash chamber. The flash chamber can be used to provide visual confirmation of proper catheter placement within a vein. The flash chamber can include a path-defining structure to facilitate identifying whether blood is continually flowing into the flash chamber. The flash chamber may also be removable from the needle hub. In some cases, the needle hub may include a paddle grip that facilitates insertion of the catheter and separation of the needle hub from the catheter adapter.

VASCULAR ACCESS DEVICE HAVING A PHOSPHORESCENT FEATURE

A catheter assembly may include a catheter hub, which may include a distal end, a proximal end, a lumen extending through the distal end and the proximal end, and a side port disposed between the distal end and the proximal end. The catheter assembly may also include a catheter extending distally from the catheter hub, an extension set coupled to the catheter hub, a catheter hub stabilization device coupled to the catheter hub, a needle hub coupled to the proximal end of the catheter hub, and an introducer needle coupled to the needle hub and extending through the catheter. One or more of the extension set, the catheter hub, or the catheter hub stabilization device may be phosphorescent. An instrument advancement device or a syringe may include one or more phosphorescent features.

Integrated catheter assembly

An integrated catheter assembly includes a housing member, an outer lumen member extending from the housing member, and a needle member slidably or movably coupled to the housing member, wherein the needle member can be extended beyond a first port of the outer lumen member in a first position and concealed in the outer lumen member in a second position. The outer lumen member has a side port between its first and second ports such that when the needle is extended in the first position and inserted into an arteriovenous fistula, blood from the arteriovenous fistula flashes into the needle member, is diverted through a relief port of the needle member out the side port of the outer lumen member for delivery to a dialysis machine. The assembly further includes an inner lumen member that is disposable through the housing member to extend out from the same the outer lumen member to provide dialyzed blood from the machine. The assembly therefore receives and delivers blood through a single injection site.

CLOSED SYSTEM CATHETER

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.

Catheter Securement Device Including Extended Anchor Pad and Release Liner Clasping Features
20230012848 · 2023-01-19 ·

Embodiments disclosed herein are directed to a securement device including a retainer defining a channel and at least one mounting wing extending therefrom. The mounting wing extends distally of an insertion site a skin surface adjacent to the insertion site to prevent “rocking” or “pistoning.” The mounting wing further includes channels of reduced thickness configured to impart malleable properties on the mounting wing. This can allow the mounting wing to be shaped to fit different portions of the patient. The retainer further includes various locking and anti-rotational features to guide the catheter into position within the retainer and further prevent “rocking” or “pistoning.” The securement device also includes a protective pad to inhibit abrasions from a medical line, spin nuts, and the like, and includes a clasping feature to retain a portion of the release liner to prevent obstructing ingress/egress of the catheter.

Full Featured Integrated Midline Catheter System with Stabilization and Near Patient Access Port Blood Draw, Infusion, and Digital Probes
20230355943 · 2023-11-09 ·

An integrated midline catheter system including a catheter adapter having a catheter extending therefrom, a stabilization platform, a proximal connector portion fluidly coupled to the catheter, and a side branch fluidly coupled to the catheter. The system also includes a near patient access port coupled to the side branch of the catheter adapter, wherein the near patient access port includes a connector portion couplable to a peripheral probe device. Furthermore, the system includes a catheter insertion device, wherein the catheter insertion device is configured to enable distal movement of the catheter adapter and catheter so as to position the catheter within a patient's vasculature.

Needle assembly with needle safety shield
11826527 · 2023-11-28 · ·

A safety needle assembly includes a housing and a cannula hub connected within a side wall of the housing, a needle connected to the cannula and extending from the cannula hub outward from a proximal end of the housing, and a spring connected with the housing. The assembly includes a barrel connected with the spring and at least partially contained within the housing to least partially cover the cannula hub. The barrel is configured for moving, sliding, traveling, activating, relocating, or transitioning from a first mode in which the barrel is securely retracted and locked at least partially within the housing and the needle extends through an aperture of the barrel and the proximal end of the housing, to a second mode in which the barrel extends from the proximal end and beyond the needle.

Needle Guard

A method of making a needle guard includes providing a mold having a portion defining a volume, the volume being a hollow cylinder with non-uniform walls with a pair of slots therein, the slots being open at one end and closed at the other end, the pair of slots having a major portion of constant width. The walls are thicker at the other end than at the one end. The method includes filling the volume with polymer and releasing a molded part from said mold and cooling a molded part resulting from the filling and releasing such that temperature that the widths of the pair of slots is non-uniform after cooling. The needle guard has upper and lower jaws defining a channel and coming together at a hinge. A winged needle can be inserted between the jaws, with the wings of the winged needle passing through slots between the jaws.
