A delivery device to deliver a guidewire through an intravenous catheter assembly may include a housing, which may include a distal end, a proximal end, and a slot. The delivery device may include a guidewire, which may include a proximal end and a distal end. The delivery device may include a guidewire hub disposed within the housing. The guidewire may be secured to the guidewire hub, and the guidewire hub may be configured to move along the slot to advance the guidewire in a distal direction. The distal end of the guidewire may include a fluid permeable structure. For example, the fluid permeable structure may include an elongated core and a coil extending around the elongated core. In some embodiments, a space between the elongated core and the coil may be configured to receive blood in response to the guidewire being inserted into the vasculature.

Vascular access instrument having a fluid permeable structure, and related devices and methods

Disclosed herein is a catheter, which in some embodiments includes a distal section configured to enter a skin insertion site. The distal section can include a tapered junction having one or more dilation structures configured to dilate the skin insertion site. The distal section can further include a distal portion extending from a distal end of the tapered junction, the distal portion having a diameter smaller than a proximal portion of the catheter. In combination, the tapered junction, the one or more dilation structures, and the specific actions of the user urging the catheter into the insertion site can result in an improved fit of the catheter in the insertion site.

Passive dilation in catheter insertion systems

An insertion device includes a housing, a sheath, a guidewire, and a wheel assembly. The housing has a distal opening at a distal end and a proximal opening at a proximal end. The sheath is coupled to the proximal end of the housing and has an interior in communication with a proximal opening of the housing. The guidewire extends through the proximal opening and into the sheath. The guidewire includes a feature to limit distal advancement of the guidewire. The wheel assembly is rotatably coupled to the housing and connected to the guidewire such that rotation of the wheel assembly distally advances the guidewire through the distal opening of the housing.

A sterile environment system can include an enclosure and a support system. The enclosure can include a barrier separating a sterile environment inside of the enclosure from a non-sterile environment outside of the enclosure. The barrier can include an expandable portion configured to expand from an unexpanded state to an expanded state for working within the sterile environment, and a patient-interfacing portion including a fenestration configured for placement directly over an area of interest of a patient, the fenestration having a sealed state and an unsealed state for access to the area of interest from within the sterile environment. The support system can be coupled to the patient-interfacing portion of the barrier such that it is positioned on at least opposite sides of the fenestration.

Enclosures including systems and methods thereof for establishing a sterile environment for a medical procedure

An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of using an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient and applying a contacting force to a bone beneath the insertion site with the distal end of the intraosseous needle. The contacting force can initiate a winding of a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby initiating drilling rotation of the intraosseous needle. The method can further include drilling through the bone until the intraosseous needle enters a medullary cavity of the patient.

The first arm and the second arm configured to transition between a first configuration and a second configuration, and an elongate biasing member extending from the first arm to the second arm and configured to bias the first arm and the second arm towards the second configuration. Transitioning from the first configuration to the second configuration disengages the sheath from a needle hub and engages the sheath with a tip of the elongate medical device.

Safety mechanism

Push activated intraosseous (IO) access devices include replaceable and rechargeable or non-rechargeable battery packs, or spring driven devices. Intraosseous access devices often require training to ensure correct placement of the access device. The disclosed devices include an intuitive operation with a unidirectional activation and drive force application. The trigger can be both activated and deactivated automatically to prevent premature activation and prevent 'backwalling'. The device can include various indicators to further guide a user in placing the device correctly, with little or no training. Devices can further include replaceable battery packs to ensure a full charge is available when the device is used, and to provide a multi-use device that requires less storage.
