[A metallic extractor in vascular surgery (author's transl)].

Area of Science:

• Vascular Surgery
• Biomedical Engineering
• Materials Science

Context:

• Atherosclerosis and thrombosis pose significant challenges in vascular surgery.
• Existing mechanical disobstruction techniques may have limitations.
• Development of specialized surgical tools is crucial for improving patient outcomes.

Purpose:

• To develop and validate a series of metallic extractors for mechanical vascular disobstruction.
• To assess the safety and efficacy of spring-based extractors in removing vascular obstructions.
• To provide an alternative solution for complex cases where other techniques have failed.

Summary:

• Five metallic extractors utilizing steel spring extension were designed and refined.
• The extractors function as fine probes suitable for both venous and arterial procedures.
• Testing confirmed that the spring pressure is below the mechanical resistance threshold of healthy vascular walls.
• Successful removal of atheromatous fragments and clots was achieved, even after prior interventions failed.

Impact:

• These spring-based extractors offer a promising advancement in mechanical vascular disobstruction.
• The devices demonstrate adaptability and effectiveness in clearing arterial and venous blockages.
• Potential to improve surgical success rates and reduce complications in vascular interventions.
