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.

Mechanical dilator

Rapidly insertable central catheters ('RICCs'), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.

Rapidly insertable central catheters, introducers, insertion devices including combinations and methods thereof

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

Embodiments disclosed herein are directed to catheter placement systems including distally extendable support devices. When placing elongate catheters advanced insertion systems are required to maintain a 'touch-free' insertion. Further longer needles are desirable to access deeper veins or penetrate deeper surface tissues. Distally extendable support devices provide columnar support to one of the elongate catheter or the needle to prevent buckling or kinking of the catheter, and maintain the needle tip within a predetermined bending arm distance. This prevents the user from contacting one of the needle or the catheter directly to provide additional support, maintaining a “touch-free” insertion.

Optimized structural support in catheter insertion systems

Elongate blood flash flow paths can be detrimental to the operation of catheter placement systems by delaying the indication time, reducing the efficacy of the vacuum, or increasing the chance of clotting. Catheter placement systems with reduced blood flash fluid paths include blood flash indicators having a proximally slidable syringe barrel and plunger that is fixedly attached to the system housing. By reversing the operation of the blood flash indicator syringe, the clinician maintains the advantages of a visual and tactile feedback while shortening the blood flow path between the needle tip and syringe barrel. Catheter placement systems also include a needle interface structure configured to further shorten the blood flash fluid path.

Fluid path optimization in catheter insertion systems

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.

Constant-torque intraosseous access devices and methods thereof

Devices and methods for an autovance intraosseous device. The autovance intraosseous device can include a trigger activated system or pressure activated system that causes a needle to advance distally for a predetermined distance. The predetermined distance ensures a needle tip extends through the bone cortex, to access the medullary cavity, without penetrating a far wall of the medullary cavity. The advancement can be driven by a spring based system or an electric motor.

Autovance feature of an intraosseous device

Constant-torque intraosseous access devices and methods thereof are disclosed. 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 such an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient; applying force to bone at the insertion site with the distal end of the intraosseous needle, which starts winding a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby starting rotation of the intraosseous needle; and drilling through the bone until the intraosseous needle enters a medullary cavity of the patient, thereby achieving intraosseous access with the intraosseous access device.

Disclosed herein are intraosseous access devices having various operating mechanisms, as well as methods of the intraosseous access devices. For example, an intraosseous access device includes, in some embodiments, a constant-torque spring assembly, a drive shaft, an intraosseous needle, and an interlock mechanism. The constant-torque spring assembly is disposed in a housing, and the drive shaft extends from the housing. The drive shaft is coupled to the constant-torque spring assembly. The intraosseous needle is coupled to the drive shaft. The intraosseous needle is configured for drilling through bone and providing intraosseous access to a medullary cavity of a patient. The interlock mechanism is configured to prevent rotation of the intraosseous needle and the drilling therewith until the interlock mechanism is disengaged.

Various operating mechanisms for intraosseous access medical devices and methods thereof

One embodiment relates to a snow shovel system with an extended and collapsed state. The system includes a blade member, handle, lower shaft member, and upper shaft member. One end of the lower shaft member is coupled to the blade member and the other is slidably coupled with the upper shaft member. A first end of the upper shaft member is coupled to a handle and the second end is slidably coupled with the lower shaft member. The slidable coupling between the lower and upper shaft members includes an extended state and a collapsed state in which the handle is separated from the blade member a greater distance in the extended state. The collapsed state includes translating a portion of the lower shaft member beyond the first end of the upper shaft member.
