Embolization systems and techniques for treating tumors

摘要

This invention relates to medical systems and least invasive techniques for treatment of hypervascularized tumors, both benign and cancerous, by catheter-based embolization of vessels that feed the tumor, for example in a patient's lung. The least invasive techniques typically can be performed by interventional radiologists for treatment of lung tumors. The invention also can be used to treat hypervascularized tumor tissues in other locations in a patient's body, for example, uterine fibroids and liver tumors.
