Abstract
Described are medical devices for supporting or inducing bone growth including an implant body defining one or more separation-assist lines that facilitate separation of the body into two or more substantially pre-defined pieces. The implant body can be used and implanted as a whole or may be separated into multiple pieces, some or all of which can be used at one or multiple implant sites in a patient. Separation-assist lines in implant bodies can serve a dual role in imparting increased and controlled flexibility to the overall body when used as a whole at an implant site. Also described are methods of making and using, and kits including, such medical devices.
Claims18
A medical implant device, comprising:
- a biocompatible, three-dimensional osteoconductive or osteoinductive implant body, the implant body comprising a sponge including mineral particles disposed uniformly within the sponge, said body including an upper surface, a lower surface, and side walls interconnecting the upper surface and the lower surface, wherein the implant body has a thickness of from 2 cm to 15 cm;
- and at least one separation-assist line defined in said implant body, said separation-assist line configured to facilitate separation of a first portion of the implant body from a second portion of the implant body by manipulating the implant body to manually break or tear the implant body along the separation-assist line into multiple separate pieces, wherein said separation-assist line comprises at least a first score line extending inwardly from a first surface of said implant body and at least a second score line extending inwardly from a second surface of said implant body, said second score line oppositely faced to and aligned with said first score line, and said first score line and second score line having a depth that comprises 20% to 60% of said thickness of the implant body and the sponge comprising fibrillar and non-fibrillar collagen and the implant comprises a plurality of said separation-assist lines extending only partially across a width of the implant body.
A medical device suitable for implant to support or induce bone growth, the device comprising:
- an osteoinductive or osteoconductive implant body, said implant body defining at least one separation-assist line configured to facilitate separation of a first portion of the implant body from a second portion of the implant body into multiple separate pieces by manipulating the implant body to manually break or tear the implant body along the separation-assist line, and said implant body comprises a sponge and a mineral disposed uniformly throughout the sponge, and the implant body has a thickness of from 2 cm to 15 cm, and wherein said separation-assist line comprises at least a first score line extending inwardly from a first surface of said implant body and at least a second score line extending inwardly from a second surface of said implant body, said second score line oppositely faced to and aligned with said first score line, and said first score line and second score line having a depth that comprises 20% to 60% of said thickness of the implant body and the sponge comprises fibrillar and non-fibrillar collagen and the implant comprises a plurality of said separation-assist lines extending only partially across a width of the implant body.
A medical product, comprising:
- an osteoinductive or osteoconductive implant body, said implant body defining at least one separation-assist line configured to facilitate separation of a first portion of the implant body from a second portion of the implant body by manipulating the implant body to manually break or tear the implant body along the separation-assist line into multiple separate pieces;
- and packaging enclosing said implant body in a sterile condition, wherein said implant body comprises a sponge and a mineral disposed uniformly throughout the sponge and said implant body has a thickness of from 2 cm to 15 cm and wherein said separation-assist line comprises at least a first score line extending inwardly from a first surface of said implant body and at least a second score line extending inwardly from a second surface of said implant body, said second score line opposite faced to and aligned with said first score line, and said first score line and second score line having a depth that comprises 20% to 60% of said thickness of the implant body and the sponge comprises fibrillar and non-fibrillar collagen and the implant comprises a plurality of said separation-assist lines extending only partially across a width of the implant body.
