In 2012, we made a $2 million investment in a da Vinci robotics-assisted surgery suite, making it the only piece of robotic surgery equipment on the IH-35 Corridor between Austin and San Antonio. This approach uses a robotic surgical system that provides your surgeon with better vision, precision and control. It requires only a few small incisions, so you can get back to your life faster, without the usual recovery following major surgery. It features a magnified 3D high-definition vision system and tiny wrist instruments that bend and rotate far greater than the human hand. Your surgeon is 100% in control of the da Vinci system at all times and the da Vinci technology translates your surgeon’s hand movements into smaller, precise movements of tiny instruments inside your body. The system has several unique features designed to provide additional clinical benefits and efficiency in the operating room for the physicians who are utilizing the rapidly emerging technology.

Universal Masking

We at CHRISTUS Health value your health and safety. Consistent with recommendations from the CDC and the Texas Medical Board, we are requiring all patients, visitors and employees to wear a mask while within our facilities. Masks are not advised for children under age 2. Please bring your mask from home with you to your appointment. Any double layered cloth mask covering your nose and mouth is appropriate for visiting our clinics as long as it does not have an exhalation valve. If you cannot come alone to your appointment, please bring no more than 1 essential visitor with you.

If you are ill with fever and cough or shortness of breath, please contact your clinician's office for instructions before coming into the clinic. We appreciate the opportunity to serve you. These measures are just a few steps we are taking to ensure to provide you and all others a safe environment.
