A multi-lumen extension system may include a first lumen forming a fluidic channel within the multi-lumen extension system; a second lumen forming a non-fluidic channel within the multi-lumen extension system; a patency instrument housed within the second lumen; a seal between the first lumen and the second lumen to prevent fluid from entering the second lumen from the first lumen; and a grip formed along the second lumen and operatively coupled to the patency instrument housed within the second lumen to selectively advance the patency instrument along the second lumen.

Multi-lumen extension system

An intravenous catheter device can have a probe with a selectively permeable distal end. The probe can be inserted through a catheter while the catheter is positioned intravenously to facilitate fluid flow into or out from the catheter such as by removing an occlusion or repositioning the catheter. Due to its selective permeability, the distal end of the probe can minimize the likelihood of the probe becoming occluded while it is inserted intravenously and may provide control over the rate of fluid flow into or out from the catheter.

Intravenous catheter device having a probe with a selectively permeable distal end

A fluid transfer device including a catheter, an introducer adapted to attach the device to a peripheral intravenous line (PIV), an actuator movably coupled to the introducer, and a catheter support movably coupled to the introducer. The catheter support is positioned between the actuator and the distal end of the introducer. The actuator moves the catheter between a first position disposed within the introducer and a second position where the end of the catheter extends beyond the end of the introducer and into the PIV. The catheter support includes a rigid or collapsible tether and a hub attached to the tether and defining a passageway. The catheter extends from the actuator through the passageway of the catheter support to the distal end of the introducer. As the actuator moves the catheter, the actuator contacts the catheter support and moves the catheter support with respect to the introducer.

System for reduced buckling of a probe during deployment of a blood draw device

A probe delivery device can include a probe delivery mechanism that facilitates advancing a probe through an IV catheter. The probe delivery mechanism can be housed within a compartment of the probe delivery device and can include a probe that extends from the compartment into a fluid pathway formed within the probe delivery device. A portion of the probe delivery mechanism can extend out from the housing to enable a clinician to advance and retract the probe. The probe delivery device may include a vacuum tube receiver or a connector to enable a blood draw or fluid injection to be performed using the probe delivery device.

An instrument delivery device to couple to a vascular access device. The instrument delivery device may include a housing, which may include a distal connector, a proximal connector, and a lumen extending through the distal connector and the proximal connector. The instrument delivery device may include a vascular access instrument, which may include a distal end and a proximal end. The vascular access instrument may be disposed within the lumen of the housing in a coiled position. The vascular access instrument may be configured to move from the coiled position to an uncoiled position and advance through the distal connector. The vascular access instrument may extend through the vascular access device into vasculature of a patient.

Vascular instrument delivery device and related systems and methods

A mechanical dilator is disclosed, which can include a first arm coupled to a second arm by a fulcrum, the first arm and the second arm cooperatively defining a lock and stop mechanism configured to limit lateral movement of the first arm with respect to the second arm. The mechanical dilator can further include a dilator body having a first side extending from the first arm and a second side extending from the second arm, where the fulcrum is configured to translate lateral movement of the first arm relative to the second arm to lateral movement of the first side relative to the second side.

An instrument advancement device may include a housing and an extension tube extending through the housing. A wedge may be disposed within the housing. The wedge may include an arc-shaped channel. A pair of opposing pinch members configured to pinch the extension tube may be disposed within the housing and configured to move along the extension tube. An instrument may extend through the arc-shaped channel. A first end of the instrument may be fixed. In response to moving the housing distally along the extension tube, the pair of opposing pinch members may push the wedge distally. In response to movement of the wedge distally a first distance, a second end of the instrument may be configured to advance distally a second distance. A support element or compressible element may be disposed within a lumen of the extension tube to support the instrument.

Instrument advancement device having an anti-buckling feature

A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end and the proximal end. The catheter assembly may include a catheter secured within the catheter adapter and extending from the distal end of the catheter adapter. The catheter adapter may be configured to move between a first position and a second position. In response to the catheter adapter moving from the first position to the second position, an angle of the catheter adapter with respect to an insertion surface may be configured to increase, which may improve patency of the catheter assembly and alignment of a fluid path of the catheter assembly with vasculature of a patient.

Catheter assembly with angle changing and related methods

An IV device assembly may include a lumen forming a fluidic channel within the IV device assembly. The lumen may be fluidically coupled to a vascular access device (VAD) coupler via a funnel coupler, and an IV device assembly coupler at a proximal end of the lumen. The IV device assembly may also include one or more of the following: a collapsible sleeve formed coaxially around a first portion of the lumen and mechanically coupled to the funnel coupler, a probe formed along a second portion of the lumen within the collapsible sleeve and into the VAD coupler, a translation handle that translates the probe out of a distal end of the VAD coupler, and a fixed grip formed around the lumen to maintain a position of the IV device assembly relative to the translation handle.

An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.

An extension set may include a tube having an outer surface. An instrument, such as a tubing or a probe, may be disposed within the tube and may include a proximal end and a distal end. A translation handle may be coupled to the outer surface of the tube and may move along the outer surface between a proximal position and a distal position to translate the distal end of the instrument between a retracted position and an advanced position. In the advanced position, the distal end of the instrument may extend beyond the distal end of the tube and into a catheter assembly and/or vasculature of a patient.

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.
