STENT DEVICES FOR SUPPORT, CONTROLLED DRUG DELIVERY AND PAIN MANAGEMENT AFTER VAGINAL SURGERY

摘要

Stent devices comprising an inflatable inner balloon defined by an envelope and an outer balloon surrounding the inner balloon concentrically, the outer balloon serving as a therapeutic agent reservoir used for controlled therapeutic agent delivery. In some embodiments, the outer balloon has two separate walls which define its volume and is independently inflatable. In some embodiments, the two concentric balloons form a substantially cylindrical structure which has a proximal end and a distal end. A catheter carrying inflation and drainage lumens extends outward from the proximal end. In some embodiments, the distal end includes an embedded cervix accommodating tip or has a non-embedded cervix accommodating tip attached thereto. The stent devices can be used to maintain the integrity and placement of vaginally placed mesh or graft after reconstructive procedures, prevent vaginal hematoma formation and bleeding, provide pain control after surgery and deliver antibiotics or hormones to the vaginal epithelium.
