US Patent 11510690 Vibrational catheter devices and methods for making same

A method for making a vibrational catheter device includes providing a transition connector comprising a proximal portion, a distal portion, and a tapered portion that defines a tapered outer surface of the transition connector, the proximal portion being wider than the distal portion, and the transition connector having a bore disposed within the tapered portion; inserting a proximal end of an ultrasound transmission member into the bore; and deforming at least part of the transition connector at the tapered outer surface so as to apply greater force to the wider proximal portion than to the distal portion to secure the proximal end of the ultrasound transmission member within the bore.
