We specialize in minimally invasive, catheter-based therapies that often avoid open surgery. Our focus is precision, safety, and long-term outcomes – tailored to your individual situation.

What to expect

  • Minimally invasive, catheter-based therapies; many procedures with short stay or outpatient pathways.
  • Clear evaluation: we review prior records/imaging and discuss options in plain language.
  • During treatment: local anesthesia or conscious sedation; focus on safety and precision.
  • After treatment: early mobilization, structured follow-up, and tele-consults on request.
