The present disclosure provides a medical device comprising an actuator restraining assembly configured to assist in restraining a catheter shaft in a deflected configuration. The actuator restraining assembly may include a brake element, a release element, a connecting sheath, and a connecting rod disposed in a catheter handle, wherein the connecting sheath and connecting rod are attached to an actuator mechanism, and wherein the at brake element is attached to the connecting sheath and the release element is attached to the connecting rod. The brake element is sized and configured to contact an inner wall of the handle to thereby provide resistance to movement of actuator mechanism in a proximal direction with respect to the handle. In one embodiment, the actuator restraining assembly is configured to allow for temporary, i.e., reversible, restraining of the catheter shaft in the deflected configuration.

An IV catheter-placement device and method thereof. The IV catheter-placement device can include a cartridge and a case fixedly disposed over the cartridge. The cartridge can include a barrel having a release button, a spring-loaded needle extending from the barrel, and an IV catheter including a catheter hub slidably disposed over the needle. The case can include a deployment button configured to slide the IV catheter over the needle. The deployment button can also be configured to press the release button when the deployment button slides into the release button. A spring compressed between a needle hub and a distal-end portion of the barrel can be released when the deployment button slides into the release button. An entirety of the needle is subsequently launched into a needle cavity of the barrel.

Provided is a tubular member moving apparatus. A tubular member moving apparatus is configured to move a tubular member and includes a first housing through which the tubular member passes, a driving roller unit including a driving roller provided in the first housing and disposed at one side of the tubular member, a driven roller unit including a first driven roller disposed at the other side of the tubular member, a first actuator configured to provide driving power for rotating the driving roller, and a second housing separably coupled to the first housing and configured to accommodate the first actuator therein.

An intravenous catheter device may include a guidewire for actively repositioning the catheter tip. A guidewire assembly may be configured to enable a clinician to actively reposition the catheter tip by moving proximal ends of segments of the guidewire. By repositioning the catheter tip, the guidewire assembly may facilitate the collection of a blood sample or the injection of a fluid through the catheter even in instances when the catheter tip has become occluded.

A catheter extension set may include a housing, which may include a distal end, a proximal end, and a lumen. The catheter extension set may include a distal connector coupled to the distal end of the housing and configured to couple to a catheter assembly. The catheter extension set may include a handle, an advancement element, and an instrument. The instrument may extend through a U-shaped channel of the advancement element and may include a fixed first end and a second end. A translation feature may be disposed between the handle and the housing and within a pocket of the advancement element such that in response to distal movement of the handle a first distance, the advancement element moves distally within the lumen the first distance and the second end of the instrument advances distally a second distance. The second distance may be at least twice the first distance.

A cannister system for containing a catheter, the cannister including a drive mechanism for driving the catheter from the cannister and into a luminal network of a patient, the cannister including an entrance point for insertion of a tool into the catheter.

Disclose herein are embodiments related to a delivery system for performing a minimally invasive procedure, the system including one or more station legs configured to attach to an operating surface and a cross-beam connected to the one or more station legs and running from 0° to 45° relative to a top of the operating surface, wherein a distance between the operating surface and the cross-beam is adjustable. Additionally, an embodiment may have a first arm connected to the cross-beam, a second arm connected to the first arm, and an axial member connected to the second arm, the axial member comprising an axial joint. The delivery system may then be configured to advance to an internal target site using the axial joint while maintaining a stationary trajectory in relation to the internal target site with the delivery system trajectory is modifiable at the target site.

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.

For robotically operating a catheter, a medical catheter is controlled by rotation of the catheter as well as steering in one or more planes of a distal end of the catheter. To robotically rotate the catheter, a handle is rotated. The steering is performed separately using one or more knobs on the handle. The rotation of the handle complicates the robotic control of the knob. A mechanical decoupling is used so that rotation of the handle maintains the position of the knob relative to the handle. Gearing or transmission is used to avoid independent control of the knob and handle rotation. In an alternative or additional approach, the handle may be robotically controlled while also guiding the catheter shaft spaced away from the handle, allowing fine-tuned control of the catheter at the access point to the patient.

A steerable medical device, such as an endoscope of an endoscopic system, including a handle and an elongate shaft extending distally from the handle to a distal tip, a motor control assembly including a motor control housing configured to detachably interface with the handle, wherein the motor control assembly includes a first motor disposed within the motor control housing and a first gear assembly disposed within the motor control housing, and a first drive axle configured to engage the first gear assembly with a first deflection mechanism disposed within the handle, the first deflection mechanism being configured to deflect the distal tip in a first plane.
