Patent number: 10695543Abstract: Apparatuses and methods described herein relate to treating cancerous tumors using radiation therapy and chemotherapy. In some embodiments, a method of treatment includes administering radiation therapy targeting a tumor, isolating a segment of a vessel proximate to the tumor, and administering a dose of a chemotherapeutic agent to the segment of the vessel. The method can further include waiting a period of time after administering the radiation therapy before administering the dose of the chemotherapeutic agent. In some embodiments, a catheter device including first and second occluding elements can be used to isolate the segment of the vessel.Type: GrantFiled: November 8, 2017Date of Patent: June 30, 2020Assignee: RenovoRx, Inc.Inventors: Ramtin Agah, Kamran Najmabadi, Shaun R.

Patent number: 10099040Abstract: In some embodiments, an apparatus includes a first catheter movably disposed within a first lumen of a second catheter. The first catheter has a first occlusion member disposed at a distal end portion and the second catheter has a second occlusion member disposed at a distal end portion. A third catheter has a third occlusion member disposed at a distal end portion and is moveably disposable within a second lumen of the second catheter. The second catheter has a side port in fluid communication with the second lumen and the third catheter can be extended out of the second lumen through the side port. The first occlusion member, second occlusion member and third occlusion member can collectively isolate a target region including a portion of a first body lumen (e.g., a main vessel) and a portion of a second body lumen (e.g., a branch of the main vessel).Type: GrantFiled: December 3, 2015Date of Patent: October 16, 2018Assignee: RenovoRx, Inc.Inventors: Ramtin Agah, Kamran Najmabadi, Shaun R.

Publication number: 20160082178Abstract: In some embodiments, a method includes introducing a catheter device into a target artery within a patient where the target artery is near a tumor. The catheter device includes a distal occlusion member and a proximal occlusion member spaced apart from the distal occlusion member. The distal occlusion member is positioned relative to the proximal occlusion member such that an isolated region of the target artery is defined between the distal occlusion member and the proximal occlusion member causing cessation of blood flow in the isolated region. A contrast agent is injected into the target artery and travels to at least one feeder vessel leading to the tumor. A target region in the patient, including the target artery and the tumor, is imaged and a tumor feeder vessel is identified within an image based on the contrast agent visible within the tumor feeder vessel within the image.Type: ApplicationFiled: December 3, 2015Publication date: March 24, 2016Applicant: RenovoRx, Inc.Inventors: Ramtin AGAH, Kamran NAJMABADI, Shaun R.
