Abstract
A method of radio-ablation in conjunction with embolic implants used for pre-embolization of branch arteries in radio-ablation of the liver or other diseased tissue.
Claims20
A method for radio-ablation of a diseased region of tissue within the body of a patient, where said diseased region is proximate healthy tissue or organs, wherein said diseased region and healthy tissue are supplied with blood through the vasculature of the patient, and the diseased tissue is supplied with blood through a main artery, and said healthy tissue or organs is supplied with blood through a branch artery of the main artery, said method comprising the steps of:
- providing an embolic implant comprising a wire-frame structure having a membrane covering at least one end of the wire-frame structure such that blood is substantially prevented from flowing through the implant when the implant is deployed in an artery;
- providing a bolus of radio-ablative particles suitable for deposition in the main artery;
- implanting the embolic implant in the vasculature at a site proximal to the diseased region;
- and
- depositing the bolus of radio-ablative particles in the main artery distal to the embolic implant site.
A method for liver cancer or a patient, with radio-ablative particles while protecting an organ proximate the liver, wherein the liver and organs are supplied with blood through the vasculature of the patient, and the liver is supplied with blood through a hepatic artery, and said proximate organ is supplied with blood through an extra-hepatic branch artery of the hepatic artery, said method comprising the steps of:
- providing an embolic implant comprising a wire-frame structure having a membrane covering at least one end of the wire-frame structure such that blood is substantially prevented from flowing through the implant when the implant is deployed in an artery;
- providing a bolus of radio-ablative particles suitable for deposition in the hepatic artery;
- implanting the embolic implant in the vasculature at a site proximal to the liver;
- and
- depositing the bolus of radio-ablative particles in the hepatic artery distal to the embolic implant site.
