Abstract: Aspects of a sheath are disclosed herein including a radially expandable outer cylinder and including a plurality of sheath fins distributed circumferentially about the inner surface of the central lumen of the sheath. Each of the fins extends along a length of the inner surface of the sheath and when the sheath not expanded, the form a continuous inner surface of the sheath lumen. Aspects also include a sheath that includes a radially expandable cylindrical outer layer a stiff inner member, an inner liner layer coupled to the inner surface of the stiff inner member; and an outer liner layer disposed between an outer surface of the stiff inner member and an inner surface of the outer layer.

Abstract: A delivery catheter with a plug ejection mechanism with a fluid filled actuator incorporated in the catheter's handle is disclosed. After delivery of RF energy, the clinician deploys the plug within the region of the lesion by activating the plug ejection mechanism.

Abstract: Implants for placement in the fallopian tube are provided that comprise radiopaque material. Implants include an inner core of silicone, a radiopaque material, an outer porous portion surrounding the inner core, and, optionally, a sound-reflecting air pocket. The implant may be detected in a fluoroscopic image and/or via ultrasound after placement of the implant in the fallopian tube.

Abstract: A delivery catheter with a plug ejection mechanism with a fluid filled actuator incorporated in the catheter handle is disclosed. After delivery of RF energy, the plug is deployed within the region of the lesion by activating the plug ejection mechanism. A delivery catheter used for female sterilization with an atraumatic ball tip and an opening in the side wall of the catheter body is disclosed. The delivery catheter includes a hinge that will yield or bend under a certain load to prevent injury to the uterine wall or fallopian tube. The side wall opening is angled to allow proper placement of a plug into the fallopian tube for occlusion of the fallopian tube.
