Described herein are methods of remodeling the base of a ventricle. In particular, methods of remodeling a valve annulus by forming a new fibrous annulus are described. These methods may result in a remodeled annulus that corrects valve leaflet function without substantially inhibiting the mobility of the leaflet. The methods of remodeling the base of the ventricle include the steps of securing a plurality of anchors to the valve annulus beneath one or more leaflets of the valve, constricting the valve annulus by cinching a tether connecting the anchors, and securing the anchors in the cinched conformation to allow the growth of fibrous tissue. The annulus may be cinched (e.g., while visualizing the annulus) so that the mobility of the valve leaflets is not significantly restricted. The remodeled annulus is typically constricted to shorten the diameter of the annulus to correct for valve dysfunction (e.g., regurgitation).

Processes for forming high density gap-filling silicon oxide on a patterned substrate are described. The processes increase the density of gap-filling silicon oxide particularly in narrow trenches. The density may also be increased in wide trenches and recessed open areas. The densities of the gap-filling silicon oxide in the narrow and wide trenches / open areas become more similar following the treatment which allows the etch rates to match more closely. This effect may also be described as a reduction in the pattern loading effect. The process involves forming then planarizing silicon oxide. Planarization exposes a new dielectric interface disposed closer to the narrow trenches. The newly exposed interface facilitates a densification treatment by annealing and / or exposing the planarized surface to a plasma.

Disclosed is a system for the treatment of cerebral aneurysms using a stent and a aneurysm pocket fill structure delivery system. One embodiment of the present invention uses a highly radiopaque, drug eluting stent that is deployed with its sidewall over the ostium of the aneurysm pocket.
