Abstract
A uterine access catheter system comprises an inner catheter and a sleeve catheter slidably disposed over the inner catheter. The inner catheter is a balloon catheter having an elastomeric balloon near its distal end and suitable for performing hysterosalpingography procedures. The sleeve catheter includes an occluding member near its distal end, and the inner catheter and outer catheter may be used together to seal against and engage the cervix of a patient undergoing hysterosalpingography or other genealogical procedures. The sleeve catheter is locked to the inner catheter, typically relative by relative rotation of the two catheters. The occluding member may be detachable and reusable. Means may be provided for drawing a vacuum between the occluding member and the balloon to further engage the cervical os.
