Single-penetration sheath for minimally invasive medical procedures

Abstract

The present invention relates to a medical sheath apparatus designed to enhance minimally invasive procedures, particularly for nerve ablation using an approximately 20-gauge needle. The sheath incorporates a distal aspect with a ventilation system, a proximal sheath flaring for needle accommodation, and a female connection for needle engagement. Cold dissipators manage temperature during procedures. The apparatus streamlines the process, requiring only one skin penetration and soft tissue tunnel, reducing patient discomfort, enhancing accuracy, and shortening procedure times. Additionally, a method is provided, involving needle withdrawal, ultrasound-guided nerve identification, and local anesthesia administration, all within the sheath. This innovation offers a versatile solution applicable to various needle sizes and anatomical locations, significantly improving minimally invasive medical interventions.
