Patent number: 6706026Abstract: A device is provided for instilling a fluid into the cavity of the uterus which avoids various disadvantages inherent in prior art devices, e.g., patient discomfort, an adjustable seal to accommodate varying dimensions of the uterus of the patient, a non-invasive, non-surgical procedure that could be performed in a relatively short period of time with little risk to the patient. The device provides a simple design to accomplish the ends described above and avoiding more complex designs including more complex procedures inherent in prior art devices. Moreover, the device and procedure may provide an even more definitive and reliable diagnostic means for the detection of abnormalities, polyps and tumors and to measure and monitor endometrial thickness within the uterus.Type: GrantFiled: August 9, 1996Date of Patent: March 16, 2004Assignee: Cook Urological IncorporatedInventors: Steven R.
