Knee Aspirate Facilitator

Tech ID:  07-02

Summary

Diagnostic aspiration and injection of medication into joints are procedures commonly indicated in medical practice today.   It is anticipated that the need for joint injections will increase due to the increased prevalence of osteoarthritis and anticipated growth in the number of novel biological compounds used in treatment.  However, Primary Care and ER physicians do not perform joint aspirations as often as clinically indicated because they are difficult to performsafely and without pain to the patient.   Dr. Meehan has designed a novel device that displaces the surrounding joint fluid, which greatly distends the joint fluid thereby increasing the success of a diagnostic "joint tap".  Administration of medications to the joint may also be facilitated, since such administration is more successful when administered into fluid near the joint.Knee aspirate illustration

Potential Applications

Simple, reusable device for knee joint aspiration and injection procedures

Advantages of Invention

  • Allows physicians who do not have the comprehensive training in joint aspirations of Rheumatologists and Orthopedic Surgeons to perform an easier, more successful, safer, and less painful procedure.
  • Improved patient comfort and lower risks for a medically important but underutilized procedure.
  • Facilitates successful aspiration and injections by Rheumatologists and Orthopedic Surgeons when more technical challenges (e.g. obesity, small joints) exist.
