Des-methyl-tocopherol therapy for restenosis prevention
First Claim
1. A method for treating a patient, comprising:
- delivering an angioplasty balloon to a site along a lumen in the patient;
inflating the balloon to contact a wall of the lumen at the site; and
locally delivering to the lumen wall at the site a volume of des-methyl tocopherol, or a precursor, analog, or derivative thereof.

Abstract
A stent is provided in combination with delivery of a tocopherol agent, and in particular a des-methyl tocopherol agent, and further beneficially a gamma-tocopherol agent, so as to reduce restenosis along the vessel or other lumenal wall where the stent is implanted. In particular applications, the stent is an endolumenal stent, and more specific beneficial applications is an endovascular stent, and the gamma-tocopherol elutes from a coating or carrier coupled with the stent. Certain combinations are provided with the des-methyl-tocopherol or phytyl substituted chromanol, e.g. gamma-tocopherol, combined with an additional agent such as an anti-restenosis agent, e.g. sirolimus, tacrolimus, everolimus, or paclitaxel, in order to provide synergistic benefit to tissues along the stented or recanalized regions. Other forms of tocopherol or tocotrienol, or other phytyl substituted chromanols, and other compounds such as palm oil, are also contemplated, for use to treat restenosis.

18. A system for treating a patient, comprising:
-
an angioplasty balloon that is deliverable to a site along a lumen in a patient and is inflatable to contact a wall of the lumen at the site; a volume of a pharmaceutically acceptable preparation of des-methyl tocopherol, or a precursor, analog, or derivative thereof; and a local drug delivery system coupled to the volume and configured to deliver the volume to the lumen wall at the site. - View Dependent Claims (19)
