Abstract
A vasoocclusive microcoil for therapeutic treatment of a patient's vasculature includes a surface with a plurality of voids or pores therein, and a therapeutic or bioactive material disposed within the plurality of voids or pores. The therapeutic or bioactive material within the plurality of voids or pores operates to accelerate a healing process in the patient's vasculature when the microcoil is introduced into the patient's vasculature.
Claims13
A vasoocclusive microcoil for therapeutic treatment of a patient's vasculature, comprising:
- a vasoocclusive microcoil including at least one flexible metal strand of a resilient material, said at least one flexible metal strand of a resilient material including at least a portion having an exterior surface forming an exterior surface of the vasoocclusive microcoil and defining a plurality of voids therein;
- and
- a therapeutic material disposed within said plurality of voids.
A method for occluding a patient's vasculature, comprising:
- providing a vasoocclusive microcoil including at least one flexible metal strand of a resilient material, said at least one flexible metal strand of a resilient material including at least a portion having an exterior surface forming an exterior surface of the vasoocclusive microcoil and defining a plurality of voids therein, and a therapeutic material disposed within said plurality of voids;
- and
- introducing said vasoocclusive microcoil into the patient's vasculature, whereby said therapeutic material can act to accelerate a healing process in the patient's vasculature.
A method for delivering a therapeutic drug to a patient's vasculature, comprising:
- providing a vasoocclusive microcoil including at least one flexible metal strand of a resilient material, said at least one flexible metal strand of a resilient material including at least a portion having an exterior surface forming an exterior surface of the vasoocclusive microcoil and defining a plurality of voids therein, and a therapeutic drug disposed within said plurality of voids;
- and
- introducing said vasoocclusive microcoil into the patient's vasculature.
