“…[41] Alternatively, chemotherapeutics can be impregnated onto microspheres for use in a technique known as drug-eluting-bead TACE (DEB-TACE). [42] In addition, microspheres can be loaded with radioactive isotopes such as yttrium-90 (Y90) for use in radioembolization, which is a contemporary alternative to TACE that has demonstrated improved efficacy specifically when used as a bridge to surgery or transplantation (Figure 2A-E). [39,43] Embolization has also demonstrated efficacy for the treatment of benign tumors.…”

Minimally invasive transcatheter embolization is a common nonsurgical procedure in interventional radiology used for the deliberate occlusion of blood vessels for the treatment of diseased or injured vasculature. A wide variety of embolic agents including metallic coils, calibrated microspheres, and liquids are available for clinical practice. Additionally, advances in biomaterials, such as shapememory foams, biodegradable polymers, and in situ gelling solutions have led to the development of novel pre-clinical embolic agents. The aim here is to provide a comprehensive overview of current and emerging technologies in endovascular embolization with respect to devices, materials, mechanisms, and design guidelines. Limitations and challenges in embolic materials are also discussed to promote advancement in the field.

“…If the origin of the targeted artery is too tiny or positioned at a sharp angle, taking into account the simultaneous blood flow, the procedure of catheterization may be prolonged and need several catheters/guidewires, resulting in increased healthcare expenses. This may lead to vascular damage and also increases the use of contrast chemicals, as well as prolonging radiation exposure for both the patient and the operator [12][13][14].…”

“…These catheters have proven to be highly beneficial in various minimally invasive clinical procedures, such as cardiac arrhythmia ablation and targeting the peripheral vasculature. However, complications related to the use of tethered devices include perioperative bleeding, thrombosis, perforation, rupture, dissection, restenosis, and endovascular leaks [12,15,16].…”

Background: Minimally invasive endovascular techniques have become crucial in medical practice for treating various vascular disorders. These techniques utilize the blood vessels as pathways to reach distant areas, allowing for precise administration of medications like chemotherapy or radiation therapy. However, there are challenges that hinder a more extensive adoption of an all-endovascular approach, including the complexity of vascular anatomy, difficulty accessing small blood vessels, vulnerability of diseased vessels, need for emergency procedures, prolonged exposure to X-ray radiation, and patient-specific factors like coagulopathy. Fresh innovations are needed to overcome these limitations. Aim of Study:This study aims to explore the current status of small-scale robots in endovascular applications. It compares their potential benefits to existing tethered clinical devices and delves into technological obstacles and clinical specifications necessary for the practical implementation of untethered robots inside blood vessels. Methods:The methods used in this study involve a comprehensive review and analysis of the existing literature on small-scale robots in endovascular applications. The review includes an examination of their potential benefits, comparison with tethered clinical devices, and identification of technological and clinical requirements for practical implementation. Results:The study highlight the potential benefits of smallscale robots in endovascular applications, including improved precision, wireless control, and autonomous operation. A comparison with tethered clinical devices reveals the advantages of untethered robots. However, there are technological obstacles and clinical specifications that need to be addressed for the practical implementation of these robots inside blood vessels. Conclusion:In conclusion, small-scale robots show promise for advancing minimally invasive endovascular treatments. They have the potential to overcome existing limitations and establish new benchmarks. However, further technological advancements and consideration of clinical requirements are necessary for their practical implementation.
