Title:
SYSTEMS AND METHODS FOR AUTOMATED PERIPHERAL VESSEL CATHETERIZATION
Document Type and Number:
WIPO Patent Application WO/2023/121860
Kind Code:
A3
Abstract:
A device for catheterization includes a catheter sheath support mounted to a catheterization device and holding a catheter sheath, a carriage supporting a guide needle, and a connector to removably engage the catheter sheath support to the carriage. The carriage translates along an axis of insertion of the guide needle independent of the catheter sheath support when disengaged from the connector. An actuator controls separation of the carriage from the catheter sheath support at a uniform velocity in response to disengagement of the connector. Translation and separation may be automated. In response to detection of the vessel wall puncture, the carriage automatically releases from the catheter sheath support and retracts along the axis of insertion at the uniform velocity relative to the catheter sheath support, and the catheter sheath automatically advances into the target vessel along the axis of insertion at the uniform velocity while the carriage retracts.
