Research on robotically steerable guidewires has surged in the past decade because of their potential in addressing difficulties related to endovascular interventions. These microscale devices exhibit unique challenges in design, fabrication, and control, not necessarily present in mesoscale continuum robots such as robotic catheters and endoscopes. Existing literature on surgical robots mainly addresses advancements in robotic surgery with a focus on current trends in specific clinical procedures. Our article aims to bridge this gap by reviewing current clinical practices in endovascular interventions, highlighting the clinical motivations for the development of robotically steerable guidewires, and detailing the current advancements and future prospects in topics related to these devices.

Bronchoalveolar lavage (BAL) is a minimally invasive procedure for diagnosing lung infections and diseases. However, navigating tortuous lung anatomy to the distal branches of the bronchoalveolar tree for adequate sampling using BAL remains challenging. Continuum robots have been used to improve the navigation of guidewires, catheters, and endoscopes and could be applied to the BAL procedure as well.

Conventional methods, such as open and arthroscopy-assisted surgery, still encounter challenges in terms of tool flexibility when addressing knee diseases in patients. Robotics has enhanced the precision and efficiency of numerous surgical procedures. However, there is still a lack of minimally invasive surgical tools capable of flexibly resecting knee lesions.

Minimally invasive endovascular and transcather procedures frequently involve delivering tools to the surgical site via a guidewire. Even when made steerable, the guidewire tip has the potential to cause tissue damage while traversing the vasculature and the connected organs. In this work, a methodology is introduced to integrate a balloon onto a tendon-driven robotically steerable guidewire to cushion the contact with tissue during traversal, stabilize within the vasculature once the guidewire has passed the surgical site, and arrest bloodflow to prevent distal embolization.

The treatment of many intravascular procedures begins with a clinician manually placing a guidewire to the target lesion to aid in placing other devices. Manually steering the guidewire is challenging due to the lack of direct tip control and the high tortuosity of vessel structures, potentially resulting in vessel perforation or guidewire fracture. These challenges can be alleviated through the use of robotically steerable guidewires that can improve guidewire tip control, provide force feedback, and, similar to commercial guidewires, are inherently safe due to their compliant structure.
