A recently granted patent (Publication Number: US11759613B2) describes a method for introducing an interventional device into an artery. The method involves the use of an arterial access sheath and two dilators with different bending stiffnesses.
The first dilator, which has a tapered distal tip and a first internal guidewire lumen, is introduced into the artery through the access site while positioned within the arterial access sheath. The first dilator is then removed from the sheath.
Next, the second dilator, which also has a tapered distal tip and a second internal guidewire lumen, is introduced into the internal delivery lumen of the sheath while the sheath body is still positioned within the artery. The distal region of the second dilator has a bending stiffness that is less than the bending stiffness of the distal region of the first dilator.
The patent also includes additional claims related to the flexibility and length of the dilators, the diameter of the internal guidewire lumens, the presence of a radiopaque tip marker, the configuration of the dilator hubs, and the structure of the arterial access sheath.
Overall, this patent describes a method that allows for the controlled and precise introduction of an interventional device into an artery using a combination of dilators with different bending stiffnesses. The method may have applications in various medical procedures involving arterial access, such as carotid artery interventions.
