Abstract

A covering for delivering a substance or material to a surgical site is provided. The covering, with substance provided therein, may be referred to as a delivery system. Generally, the covering may be a single or multi-compartment structure capable of at least partially retaining a substance provided therein until the covering is placed at a surgical site. Upon placement, the covering may facilitate transfer of the substance or surrounding materials. For example, the substance may be released (actively or passively) to the surgical site. The covering may participate in, control, or otherwise adjust the release of the substance. In various embodiments, the covering is suitable for a variety of procedure specific uses. Implantation tools may be provided for placing the covering at a surgical site. Kits may be provided including variously sized or shaped coverings and one or more tools for use in placing the covering.
