Abstract
A device is provided for precision positioning of a medical instrument within a biotic structure through a hole in an exterior wall of the biotic structure. A structural member of the instrument extends through the hole of the biotic structure at a puncture point with the instrument disposed on the structural member at a first end within the biotic structure. A medical instrument holder disposed at a second end of the structural member outside the biotic structure is provided for retaining a medical instrument at a predetermined angle. The device also includes instrument manipulating apparatus for supporting and positioning the instrument holder to position the medical instrument at the desired location while maintaining the structural member substantially stationary in the plane of the exterior wall at the puncture point. A selectively moveable support has legs that are independently pivotally rotatable about a joint, such as a ball and socket joint. The moveable support is coupled to actuators for activating the selectively moveable support. An input device, which generates a positioning signal that corresponds to the surgeon's desired positioning of the medical instrument, is also included. A computer for controlling the actuators determines the correct movement of the selectively moveable support based on the electronic signal of the input device, which thereby positions the medical instrument at the correct location.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
