Abstract
An intracranial stent includes a proximal end, a distal end, and a tubular sidewall extending there between and a patch covering at least a portion of the sidewall; wherein the patch is capable of diverting blood flow past the neck of an intracranial aneurysm. The patch may be made of a photon-activatable material or a tightly woven metal material with a density greater than a density of the sidewall itself.
Claims13
A method of treating a cerebral aneurysm of a patient comprising the steps of:
- providing a stent delivery system, wherein the stent delivery system comprises a microcatheter comprising a proximal end portion and a distal end portion, wherein the distal end portion is covered by a radiation-shielding element;
- positioning the delivery system within a cerebral vessel so that the distal end of the catheter is disposed at a neck of the aneurysm;
- deploying an intracranial stent, wherein the intracranial stent comprises:
- a proximal end;
- a distal end;
- a tubular sidewall extending between the proximal end and the distal end;
- and
- a photon-activatable patch covering at least a portion of the sidewall;
- and
- activating the photon-activatable gel on the stent using a photon source, wherein when the photon-activatable gel is activated the gel expands and covers the aneurysm orifice to seal the aneurysm off from a parent circulation.

A method of treating a cerebral aneurysm comprising the steps of:
- providing a coil delivery system, wherein the coil delivery system comprises a microcatheter comprising a proximal end portion and a distal end portion, wherein the distal end portion is covered by a radiation-shielding element;
- positioning the delivery system within a cerebral vessel so that the distal end of the catheter is disposed at a neck of the aneurysm;
- deploying an embolic coil coated with a photon-activatable gel material into the aneurysm cavity;
- and
- activating the photon-activatable gel on the coil using a photon source, wherein activation of the gel leads to physical enlargement of the embolic coil within the aneurysm cavity causing isolation of the aneurysm from the circulation.
