Segmented delivery system
View Patent ↗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 may be formed of a collagen material and is suitable for a variety of procedure specific uses.
1. A kit comprising a tool and a bone repair delivery system near a bone, the tool comprising: a handle connected to a docking port, said docking port configured to attach to a rigid structure attached to the bone repair delivery system, and a plunger disposed in said handle configured to push and release said rigid structure into a bone location; and the bone repair delivery system comprising a plurality of operably linked segments of at least two types: a first segment type comprising a covering material defining at least one compartment configured to retain a bone growth substance, the covering material comprising a biodegradable mesh polymer, and a second segment type configured to connect segments of the first type.
2. A kit of claim 1 , wherein the bone repair delivery system comprises segments of the first type that vary in size.
3. A kit of claim 1 , wherein the second segment type is comprised of a covering material.
4. A kit of claim 1 , wherein the segments of the first type are pre-filled with approximately equivalent amounts of bone growth substance.
5. A kit of claim 1 , wherein the second type segments are configured to retain little or no bone growth substance.
6. A kit of claim 1 , wherein the bone repair delivery system is designed for use in a sternum closure procedure.
7. A kit of claim 1 , wherein the bone repair delivery system is used in filling an irregular shaped bone void.
8. A kit of claim 7 , wherein at least two segments of the first type within the bone void are packed substantially parallel.
9. A kit of claim 1 , wherein the bone repair delivery system comprises a bone growth substance contained within the covering material, the volume of the bone growth substance is less than the maximum volume of the at least one compartment, wherein said covering material containing said bone growth substance is configured to fit an irregular bone void.
10. A kit of claim 1 , wherein the bone delivery system is configured to be used in a discectomy.
