Abstract
Implantable tensile load-bearing grafts having synthetic components stitched through biological components are disclosed. The synthetic components can be biodegradable and/or non-biodegradable and of differing tensile strengths from each other and the biological component. Methods of making the grafts are also disclosed.
Core Innovation
The invention relates to an implantable orthopedic device configured as a tensile load bearing element in a target site. The device includes a biological component comprising a soft tissue and a hard tissue, and a first synthetic component and a second synthetic component. The first synthetic component sustains a first portion of a tensile load, and the second synthetic component sustains a second portion of the tensile load.
The second synthetic component extends in multiple directions through the soft tissue and through the hard tissue. The hard tissue has hard tissue length, hard tissue width, and hard tissue height, with the hard tissue length greater than the hard tissue width and the hard tissue height, and the soft tissue has soft tissue length, soft tissue width, and soft tissue height, with the soft tissue length greater than the soft tissue width and the soft tissue height.
The hard tissue comprises a hard tissue first channel and a hard tissue second channel positioned at the same distance from a longitudinal center of the biological component. The hard tissue first channel has multiple turns, and the second synthetic component extends along the multiple turns. The device enables a composite load sharing between synthetic and biological components with multiple synthetic elements extending and overlapping through biological tissue using stitch patterns such as straight, zig-zag, and saw tooth, together with transition-zone overlap.
Claims Coverage
The document provides one explicitly independent claim directed to an implantable orthopedic device for tensile load bearing using a biological soft tissue and hard tissue component connected with first and second synthetic components. Multiple dependent claims refine channel and component structures and add geometric and positional constraints, including bone plugs and length and overlap relationships.
Biological soft tissue and hard tissue with dual synthetic load portions
An implantable orthopedic device for implantation as a tensile load bearing element comprising a biological component with a soft tissue and a hard tissue, a first synthetic component configured to sustain a first portion of a tensile load, and a second synthetic component configured to sustain a second portion of the tensile load.
Second synthetic component extending in multiple directions through soft and hard tissue
The second synthetic component extends in multiple directions through the soft tissue and through the hard tissue, and extends through the hard tissue along the hard tissue length and through the soft tissue along the soft tissue length.
Relative tissue geometry and channel-based multi-turn routing
The hard tissue length is greater than the hard tissue width and the hard tissue height, and the soft tissue length is greater than the soft tissue width and the soft tissue height, with the hard tissue including a hard tissue first channel and a hard tissue second channel symmetrically positioned relative to a longitudinal center; the hard tissue first channel has multiple turns and the second synthetic component extends along the multiple turns.
First and second ends with hard tissue bone plugs
The device wherein the hard tissue includes a first bone plug at a first end of the device and a second bone plug at a second end of the device.
Overlap of synthetic components in soft tissue
The first synthetic component overlaps with the second synthetic component in the soft tissue.
Stitched second synthetic component through soft and hard tissue
The second synthetic component is stitched through the soft tissue and the hard tissue.
Second synthetic length greater than soft tissue length
The length of the second synthetic component is greater than the soft tissue length.
Second synthetic total length greater than hard tissue length
A total length of the second synthetic component is greater than the hard tissue length as measured from the hard tissue first longitudinal terminal end to the hard tissue second longitudinal terminal end.
Overall claim coverage focuses on an implantable orthopedic tensile load bearing device that uses a biological soft tissue and hard tissue connected with two synthetic components that sustain different tensile load portions, with the second synthetic component extending in multiple directions through both tissues and following a multi-turn channel geometry, including symmetric channel positioning relative to a longitudinal center.
