Sonohysterography and biopsy catheter

摘要

A single device is provided for performing the diagnostic procedures of sonohysterography and endometrial biopsy. The device includes a cervical seal to occlude the cervix and a substance delivery and removal device to deliver and remove a fluid from the uterus. The substance delivery and removal device may also be used to create a vacuum so that suction occurs near side-ports that are used to collect endometrial tissue samples from multiple locations as the device is rotated or moved laterally within the patient. Additionally, the sample may be taken using a cellular collection device.
