A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

Devices for localizing an intracerebral hematoma or blood mass in brain tissue. The devices include an elongate probe a color sensors and a light emitter on the distal end of the probe. The color sensors produce a signal corresponding to the color of light reflected into the color sensors. A display is provided to indicate the color detected.

Methods and devices for color detection to localize the blood mass of an intracerebral hematoma

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a mounting ring which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the mounting ring and the clip.

Anchoring system and method for cranial access

A camera and expandable bladed retractor system. The system includes a camera, with a distal-most optical element disposed over the proximal end of the lumen or surgical channel established by the retractor blades. The camera may be fixed to the retractor, either to the proximal end of a blade or to a frame member.

Devices and method for access and visualization for lumbar interbody fusion (LIF)

A macerating and aspiration tool for removing blood masses from the brain.

Macerating and aspiration tool for intracranial surgery

A unidirectional electrode and method for sensing and stimulating the subthalamic nucleus of the brain to treat certain disorders such as epilepsy, Parkinson's, essential tremors and dystonia.

Unidirectional electrode and method for stimulation of the subthalamic nucleus of the brain

A cannula system with a proximally mounted camera assembly, sensors or sensor pair component(s), radially fixed to the camera assembly and an image control system operable to rotate image data obtained from the camera for display on a display screen, to maintain an image in an orientation preferred by a surgeon even as the camera assembly is rotated radially about the axis of the cannula.

An anchoring system for cannulas or tools to be inserted into a surgical workspace in the body, particularly the brain, of a patient. The system comprises a grommet which may be fixed to the skull to both secure the system to the skull and protect the skull opening from passage of cannulas and tools, a resilient clip with grasping jaws adapted to firmly grasp a cannula or tool, and a flexible membrane secured to the outer rim of the grommet and the clip.

A cannula with a proximally mounted camera and proximally mounted light sources. The lighting sources have beam axes directed distally, toward a workspace at the distal end of the cannula. The light sources are coupled with focusing lenses, to reduce the beam angle of the lighting sources and reduce glare within the cannula tube.
