Abstract: A completely disposable apparatus of single unit construction designed for operative use in conjunction with a transvaginal ultrasound probe when performing transvaginal surgical procedures with ultrasonic guidance. This invention consists of a probe covering sheath containing a probe securing mechanism, an instrument or needle guide, and an ultrasound cable sleeve. When this unit is surgically sterilized and applied to the transvaginal ultrasound probe it provides an uninterrupted covering that permits the ultrasound probe and cable to be introduced into a sterile operative field while at the same time eliminating contamination of the ultrasound equipment with body fluids. Embodiments of the present invention provide a sterile plastic sheath to cover the transvaginal ultrasound probe during daily non-operative diagnostic examinations and a durable plastic sheath that when fitted over the transvaginal ultrsound probe protects it from accidental damage during storage.

Abstract: This invention provides an improved aspirating and flushing device designed for use in in vitro fertilization procedures in which eggs are delicately removed from the human ovary without need for open surgery. Although the device is intended for one-time use only, a permanent, interchangable stainless steel suction valve assembly can be substituted for the disposable valve if desired. The present invention is adaptable for both trans-abdominal laparoscopic procedures, as well as a trans-vaginal procedure that is performed with the aid of ultrasonagraphy.

Abstract: A method for delicately and gently removing an egg from the human ovary for use in in vitro fertilization and a disposable or semi-disposable surgeon's aspirating and flushing valve for performing such a removal.
