Abstract
Utilizing the technology and methods disclosed, the characteristics of flexibility and rigidity for intralumenal devices, including coaxial two piece devices such as stylet and needle sets, can be adapted by a physician or device manufacturer according to the type of procedure, the patient size and unique anatomical challenges of a given procedure. Rigidity and flexibility are actively controlled by the operator at predefined portions of a device through rotating the stylet within the cannula to bring about alignments of customized notches to impart target flexibility or rigidity profiles at specific spots on the device. The device operator is able to alter the relationship and orientation of specific notched and non-notched segments of either or both the stylet and cannula that are strategically located at said critical points along the length of the device.
