Artificial Ligaments For Joint Applications    

Ligaments incorporated into a prosthetic or natural joint exhibiting a plasticized, elongated and deformable material.


These artificial ligaments, and the associated methods for attachment of them to both natural and artificial bones, will provide major advantages to patients, physicians, and health care institutions by providing an attractive alternative to cadaver allografts as well as autografts harvested from the patient’s own tissue.

For many patients the strength of a cadaver allograft, which is commonly used for example in an anterior cruciate ligament (ACL) repair of the knee, is not adequate for them to return to the high demand sports that they love. In addition, these grafts carry a small risk of disease transmission. Autografts harvested from the patient’s own patellar tendon and hamstring tendon are stronger than cadaver grafts, but carry the disadvantage of having to cut into healthy tendon elsewhere in the patient’s body, and increased surgical pain. An artificial ligament that is stronger than native ligament is a much needed and welcome alternative.

Surgeons will find the press fit anchor system extremely easy to install, which will save them time and effort in the operating room, and increase the success rates of their repairs.

Health care institutions and insurance providers will appreciate the potentially low cost, and higher success rates of these alternatives.

In addition to their use in repairing tendon and ligament injuries, such as the ACL or Achilles tendon, these artificial ligaments can be used for stabilizing and supporting artificial prosthetic joints, which will enhance their strength and durability. Currently there is no artificial ligament or tendon on the market, so there effectively is no competition.

Some of the variations shown in the patent can also be used to anchor hardware to bone, such as fracture plates or prosthetic joints.

Primary Application of the Technology

Companies who produce surgical implants used in orthopedic surgery and for ligament and tendon repair and fracture repair.

Hand surgeons, foot surgeons, shoulder surgeons, hip surgeons, knee surgeons, sports medicine specialists, orthopedic surgeons, trauma surgeons, patients,

The Problem Solved by the Technology

Provision of a strong artificial tendon or ligament for use in stabilizing and supporting natural or prosthetic joints. Currently there is no viable artificial ligament or tendon available to use. Either tendon or ligament material is harvested from cadavers (allograft), which is not as strong as natural ligament and tendon, and carries an infection risk, or it is harvested from the patient (autograft) at a different site and transferred to the site needed, necessitating an additional site of trauma and pain and possible complications.

How the Technology Solves the Problem

This technology provides a strong, viable artificial ligament for surgical repairs. No good artificial ligament exists on the market today. This technology can be used to anchor hardware, such as fracture plates and prosthetic joints to natural bone.

Comments on Deal Structure, Potential Terms and Restrictions

The ideal scenario is a partnership with an organization that would license this technology and provide capital and expertise help to develop it to the point where it can be brought to market and thereby generate profits and royalty payments.

Additional Information

This technology is protected by United States and international patents.
