PERCUTANEOUS DELIVERY DEVICE AND METHOD FOR TENDON-LIGAMENT-MUSCLE REPAIR

摘要

Embodiments include systems, methods and devices for the percutaneous delivery of therapeutic agents to tendons, ligaments and muscle. Certain embodiments include a device comprising a needle-catheter based delivery system with adjustable characteristics to allow a clinician to control the angle and depth of needle and/or catheter deployment to a desired location. System embodiments may include a controller unit where a clinician can adjust the axial position depth and location of needles and/or catheters.

主权项

1. A device for percutaneous use comprising:
a tubular system having at least two hollow tubes, the system comprising:
an outer tube having a first proximal end, a first hollow shaft, and a first distal end; andan innermost tube, the innermost tube having a second proximal end, a second hollow shaft, and a second distal end, the innermost tube being housed coaxially within the first hollow shaft of the outer tube, the innermost tube configured to advance within the first hollow shaft of the outer tube, and wherein the second distal end of the innermost tube exits the first distal end of the outer tube; and a controller apparatus operatively coupled to the tubular system, the controller apparatus configured to adjust an angle of deployment of the tubular system in a coronal plane, and further to adjust an angle of deployment of the innermost tube in a sagittal plane independently from the outer tube, the controller apparatus further configured to adjust a length of deployment of at least one of the tubes of the tubular system.
