The present invention provides video and audio assisted surgical techniques and methods. Novel features of the techniques and methods provided by the present invention include presenting a surgeon with a video compilation that displays an endoscopic-camera derived image, a reconstructed view of the surgical field (including fiducial markers indicative of anatomical locations on or in the patient), and / or a real-time video image of the patient. The real-time image can be obtained either with the video camera that is part of the image localized endoscope or with an image localized video camera without an endoscope, or both. In certain other embodiments, the methods of the present invention include the use of anatomical atlases related to pre-operative generated images derived from three-dimensional reconstructed CT, MRI, x-ray, or fluoroscopy. Images can furthermore be obtained from pre-operative imaging and spacial shifting of anatomical structures may be identified by intraoperative imaging and appropriate correction performed.

A system provides a single composite image including multiple medical images of a portion of patient anatomy acquired using corresponding multiple different types of imaging device. A display processor generates data representing a single composite display image including, a first image area showing a first image of a portion of patient anatomy acquired using a first type of imaging device, a second image area showing a second image of the portion of patient anatomy acquired using a second type of imaging device different to the first type. The first and second image areas include first and second markers respectively. The first and second markers identify an estimated location of the same corresponding anatomical position in the portion of patient anatomy in the first and second images respectively. A user interface enables a user to move at least one of, (a) the first marker in the first image and (b) the second marker in the second image, to correct the estimated location so the first and second markers identify the same corresponding anatomical position in the portion of patient anatomy.

The timeline includes the same one or more indicators that are displayed on the graphical representation corresponding to clinical events that have occurred in connection with a patient. A selection or change of an indicator on one of the graphical representation or the electronic health record timeline triggers a corresponding selection or change of the indicator on the other of the graphical representation or the electronic health record timeline.

The present teachings provide methods for diagnosing biological conditions, including cancer. In some embodiments, a test sample is collected from a subject such as a clinical patient, wherein the test sample comprises background tissue and may or may not contain cells from a tissue of interest. Observation of a target miRNA normally present in a tissue of interest, but collected in an anatomical location ectopic to the tissue of interest, can be indicative of a biological condition. The present teachings further provide exponential amplification techniques applicable to performing these analyses.

An instrument for establishing orientation of a pelvic prosthesis comprises a tri-pod having an angularly adjustable guide rod on it. The tips of the legs define a plane, and the guide rod is set by the surgeon to a defined orientation with respect to this plane on the basis of preoperative studies. In use, two of the legs of the instrument are positioned by the surgeon at defined anatomical locations on the pelvis (e.g., a point in the region of the posterior / inferior acetabulum and a point on the anterior superior iliac spine). The third leg then lands on the pelvis at a point determined by the position of the first two points, as well as by the separations between the third leg and the other two legs. The separations are adjustable, but are preferably fixed percentages of the separation between the first and second legs. The position of the guide rod then defines with respect to the actual pelvis the direction for insertion of a prosthesis.

A method and system for patient-specific planning of cardiac therapy, such as cardiac resynchronization therapy (CRT), based on preoperative clinical data and medical images, such as ECG data, magnetic resonance imaging (MRI) data, and ultrasound data, is disclosed. A patient-specific anatomical model of the left and right ventricles is generated from medical image data of a patient. A patient-specific computational heart model, which comprises cardiac electrophysiology, biomechanics and hemodynamics, is generated based on the patient-specific anatomical model of the left and right ventricles and clinical data. Simulations of cardiac therapies, such as CRT at one or more anatomical locations are performed using the patient-specific computational heart model. Changes in clinical cardiac parameters are then computed from the patient-specific model, constituting predictors of therapy outcome useful for therapy planning and optimization.

A dynamic spine stabilization device is provided that includes at least one force imparting member, e.g., a spring. The force imparting member is adapted to deliver a force of between about 150 lb / inch and 450 lbs / inch, and restrict the relative travel distance between said first and second pedicles to a distance of between about 1.5 mm and 5 mm. The spinal stabilization devices also have a minimal impact on the location of the center of rotation for the spinal segment being treated. By providing resistance in the noted range and restricting the travel distance to the noted range, it has been found that the stabilization device provides a desired level of stabilization, as reflected by range of motion values that closely approximate pre-injury range of motion levels. In addition, the resistance levels are not so high as to alter the location of the center of rotation of the treated spinal segment from its normal anatomical location to levels previously obtained, thereby permitting substantially unimpeded angular motion despite the posterior presence of a stabilization device.

The invention provides microfabricated devices and methods for directing the growth of a cell process to form an artificial synapse. The devices are called artificial synapse chips. The artificial synapse comprises a nanofabricated aperture (about 50–100 nm in size) that connects the cell process to a chemical or electrical means of neuronal excitation. Such an aperture width mimics the length scales of a natural synapse and thus emphasizes the localized spatial relationship between a neuron and a stimulation source. The invention further provides devices and methods for regenerating a nerve fiber into an electrode. The invention thus provides a regeneration electrode that uses a novel neural interface for stimulation and that uses novel surface methods for directing neuronal growth making possible in vivo connection of the devices to neural circuitry in a retina and other anatomical locations.

Intraocular lens implant that includes a lens optic and lens haptics configured to maintain a preoperative position of the posterior lens capsule after cataract removal and insertion of a lens implant. The lens haptics have proximal and distal portions, with the distal portions lying in a common plane and the lens optic extending in a lens optic plane. The distance between the planes may be at least substantially the same dimension as or larger than a shift distance that the posterior lens capsule would otherwise traverse between its normal anatomical location and its shifted anatomical location where it not constrained. The shifted anatomical location arises naturally after both removal of cataract lens material and removal of a portion of an anterior capsule.
