A patent application (Publication Number: US20240033425A1) describes a method for producing an elastically deformable functional part for a medical device with an openable slit arrangement that widens or closes based on deformation. The method involves providing a blank made of elastic material and using ultrasound to create slits in the material. The process includes activating a sonotrode to oscillate with ultrasound frequency, moving the sonotrode and blank relative to each other to create slits, and leaving the sonotrode in a final position for a dwell time. The method also includes steps for widening the slit arrangement and applying an inhibitor material to prevent self-healing of the material.

Furthermore, the patent application details a device for producing the functional part, including a clamp device for holding the blank, a sonotrode for creating slits with ultrasound, and a spike for deformation-assisted opening of the slit arrangement. Additionally, a dosage unit is included for applying the inhibitor material to the slit wall faces. The resulting medical device with the elastically deformable functional part controls fluid flow through the device by opening and closing the slit arrangement based on deformation. The method and device described in the patent application aim to provide a unique way of producing functional parts for medical devices that can be elastically deformed and controlled for fluid stream management.
