Embodiment Construction

[0015] Various embodiments described herein provide systems for accessing and manipulating target tissue (eg, tendon tissue, ligament tissue, muscle tissue, bone tissue, etc.) under the guidance of an ultrasound imaging device. In certain embodiments, the system includes a delivery device that is pre-tuned to a frequency range of ultrasonic energy selected for debridement of pathological musculoskeletal tissue. According to certain embodiments, the delivery device (also referred to as a hand piece) includes echogenic material and / or etching to facilitate ultrasound imaging, and the delivery device is adapted for percutaneous insertion without significant skin damage. incision. The portion of the system including the delivery device and associated tubing set is optionally adapted to be discarded after a single use.

[0016] In some applications, high-frequency ultrasound transducers and associated ultrasound imaging equipment provide visual detail of tendon pathology in latera...

Abstract

Delivering ultrasound energy to the target musculoskeletal tissue site includes connecting the delivery device to a vacuum source, a fluid source, and a power signal source. The delivery device has a housing portion holding an ultrasound transducer and a tip portion with a cannula and a cannula. A cannula is connected to the ultrasound transducer and is received within the cannula to define a covered portion and an exposed portion. Ultrasonic energy is generated by sending a power signal from a power signal source to the ultrasound transducer. Ultrasonic energy is transmitted from the ultrasonic transducer to the cannula such that the exposed portion of the cannula transmits ultrasonic energy at a frequency preselected to clear musculoskeletal tissue after percutaneous insertion of the tip.

Description

Background technique [0001] Repeated movement or use of certain tissues can cause injury or painful conditions. For example, tennis elbow, or lateral epicondylalgia, is a clinical syndrome in which the patient feels pain on the outside of the elbow. This pain on the lateral elbow can worsen over time, and despite proper management, many patients develop chronic symptoms and eventually become candidates for surgery. [0002] Numerous surgical procedures have been described for the management of chronic lateral epicondylalgia. Specific surgical techniques typically require surgical dissection to pathological tissue and thus repair of surgically injured normal tissue. Certain arthroscopic techniques can be less invasive, but these arthroscopic elbow techniques can be associated with neurologic complications and can require the use of costly surgical tools and personnel. Various transcutaneous techniques have been described that drain, ablate or resect pathological tissue. How...
