NUMERICAL AND EXPERIMENTAL INVESTIGATION OF THE DYNAMIC BEHAVIOR OF VIBRATING NITI GUIDEWIRE

Research output: Contribution to conferenceAbstractpeer-review

Abstract

Minimally invasive interventions often utilise slender wires to access and navigate to target sites. These guidewires act as rails, facilitating access for other therapies. In endovascular procedures, the guidewires facilitate angioplasty balloons, stenting and other dilation procedures. Due to their small profile and flexibility, endovascular guidewires have limited ability to transfer forces to their tip and as a result cannot penetrate hard calcified blockages, commonly referred to as chronic total occlusions (CTOs) [1-2]. One method proposed to overcome this limitation is the application of vibrations to the wire. The vibrations are transmitted along the length of the wire to the distal tip, where the micro reciprocating action can ablate or disrupt calcified material [3]. To better understand how NiTi can transmit these vibrations, a straight NiTi wire of guidewire dimension, is simulated and analysed numerically, with the displacement at the wire's distal tip obtained and compared to experimental results.
