20130096377 | CATHETER WITH REMOVABLE VISION PROBE - A medical system includes a catheter and a vision probe that can be removed from the catheter and replaced with a medical probe. The vision probe can thus be used to steer and pose the catheter, and then be removed and replaced with the medical probe when a medical task such as a lung biopsy is performed. A sensor system in the catheter at least partly measures a pose of the catheter, and control logic controls actuation of the catheter to maintain the desired working configuration when the medical probe is used. A small diameter catheter can thus provide vision and biopsy functionality. | 04-18-2013 |
20130096385 | VISION PROBE AND CATHETER SYSTEMS - A medical system includes a catheter and a vision probe that can be removed from the catheter and replaced with a medical probe. Functionality for the system is divided between the catheter and the vision probe. In particular, the removable vision probe can provide imaging, illumination, irrigation, and suction that may be employed before a medical probe is deployed. The catheter can include actuation and sensing structures that are useful with or necessary for both vision and medical probes. Accordingly, the catheter can maximize available space for probes and still provide all necessary functions for use of a medical probe when the vision probe is removed. | 04-18-2013 |
20130331730 | Systems and Methods for Cleaning a Minimally Invasive Instrument - An anatomical probe system comprises an elongated flexible body and an operational component extending within a channel of the flexible body. The system also comprises a support member at a distal end of the elongated flexible body. The support member includes a fluid director adapted to direct a fluid from the channel toward the operational component. The fluid may be automatically directed towards the operational component in response to detecting a material obstruction of an image. | 12-12-2013 |
