Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, or external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

This invention is methods and apparatus for occluding blood flow within a blood vessel (22). In a first series of embodiments, the present invention comprises a plurality of embolic devices (16) deployable through the lumen (12) of a conventional catheter (10) such that when deployed, said embolic devices (16) remain resident and occlude blood flow at a specific site within the lumen of the blood vessel (22). Such embolic devices (16) comprise either mechanical embolic devices that become embedded within or compress against the lumen of the vessel or chemical vaso occlusive agents that seal off blood flow at a given site. A second embodiment of the present invention comprises utilization of a vacuum / cauterizing device capable of sucking in the lumen of the vessel about the device to maintain the vessel in a closed condition where there is then applied a sufficient amount of energy to cause the tissue collapsed about the device to denature into a closure. In a third series of embodiments, the present invention comprises the combination of an embolization facilitator coupled with the application of an energy force to form an intraluminal closure at a specified site within a vessel.

A novel approach to diagnostic and therapeutic interventions in the peritoneal cavity is described. More specifically, a technique for accessing the peritoneal cavity via the wall of the digestive tract is provided so that examination of and / or a surgical procedure in the peritoneal cavity can be conducted via the wall of the digestive tract with the use of a flexible endoscope. As presently proposed, the technique is particularly adapted to transgastric peritoneoscopy. However, access in addition or in the alternative through the intestinal wall is contemplated and described as well. Transgastric and / or transintestinal peritoneoscopy will have an excellent cosmetic result as there are no incisions in the abdominal wall and no potential for visible post-surgical scars or hernias.

Tissue visualization and manipulation systems are described herein. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to a region of tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid, such as saline, can be pumped into the imaging hood until the fluid displaces any blood, thereby leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Additionally, any number of therapeutic tools can also be passed through the deployment catheter and into the imaging hood for treating the tissue region of interest.

A scanning endoscope, amenable to both rigid and flexible forms, scans a beam of light across a field-of-view, collects light scattered from the scanned beam, detects the scattered light, and produces an image. The endoscope may comprise one or more bodies housing a controller, light sources, and detectors; and a separable tip housing the scanning mechanism. The light sources may include laser emitters that combine their outputs into a polychromatic beam. Light may be emitted in ultraviolet or infrared wavelengths to produce a hyperspectral image. The detectors may be housed distally or at a proximal location with gathered light being transmitted thereto via optical fibers. A plurality of scanning elements may be combined to produce a stereoscopic image or other imaging modalities. The endoscope may include a lubricant delivery system to ease passage through body cavities and reduce trauma to the patient. The imaging components are especially compact, being comprised in some embodiments of a MEMS scanner and optical fibers, lending themselves to interstitial placement between other tip features such as working channels, irrigation ports, etc.

The methods shown provide for the minimization of extravasation during arthroscopic surgery. Use of an anti-extravasation sheath having at least one drainage aperture allows a surgeon to drain excess fluids from the tissue surrounding the surgical field during an arthroscopic surgical procedures when the drainage aperture is disposed within the tissue surrounding an arthroscopic surgical field outside of the joint capsule. The method of performing arthroscopic surgery may further include providing fluid inflow and outflow to the joint capsule through inflow / outflow holes in the anti-extravasation sheath.
