Device For Navigating A Medical Instrument Relative To A Patient Anatomy
The present invention relates to a device for navigating a medical instrument relative to a patient anatomy, a method for navigating a medical instrument relative to a patient anatomy, and a program element which, when executed by a computer, executes this method. The device comprises a position determination unit, a computing unit and a navigation display. The position determination unit comprises a sensor module configured to acquire current 3D data of the patient anatomy. The position determination unit further comprises a position sensor which is configured to acquire current movement data of the medical instrument. The computing unit is configured to match the current 3D data of the patient anatomy and the current movement data of the medical instrument with preoperative image data of the patient anatomy and, on this basis, to calculate navigation information for the medical instrument. The navigation display is configured to show the calculated navigation information.
SYSTEMS, METHODS, AND DEVICES FOR REGISTERING AND TRACKING ORGANS DURING INTERVENTIONAL PROCEDURES
Systems, methods, and devices are provided for assisting or performing guided interventional procedures using specialized catheters and inserts. A bend altering device is introduced into a conduit in an organ causing it to take on a tortuous path and to assist in its visualization. A scan is performed of a patient's anatomy to identify targets critical structures and the path of the conduit. A bend altering device containing position indicating elements is placed into the conduit in the same path as before the scan. During a procedure, the pre-procedure scans may be registered to the patient using the location of the position indicating elements in the conduit. This registration may be used in an intervention to guide instruments and templates to obtain diagnostic information or provide therapy to the targets identified in the scans.
Interventional device recognition
The present invention relates to an apparatus for tracking a position of an interventional device respective an image plane of an ultrasound field. The position includes an out-of-plane distance (Dop). A geometry-providing unit (GPU) includes a plurality of transducer-to-distal-end lengths (Ltde.sub.1 . . . n), each length corresponding to a predetermined distance (Ltde) between a distal end of an interventional device and an ultrasound detector attached to the interventional device, for each of a plurality of interventional device types (T.sub.1 . . . n). An image fusion unit (IFU) receives data indicative of the type (T) of the interventional device being tracked; and based on the type (T): selects from the geometry-providing unit (GPU), a corresponding transducer-to-distal-end length (Ltde); and indicates in a reconstructed ultrasound image (RUI) both the out-of-plane distance (Dop) and the transducer-to-distal-end length (Ltde) for the interventional device within the ultrasound field.
SYSTEMS AND METHODS FOR TREATMENT OF PROSTATIC TISSUE
A prostate therapy system is provided that may include any of a number of features. One feature of the prostate therapy system is that it can access a prostate lobe transurethrally. Another feature of the prostate therapy system is that it can deliver condensable vapor into the prostate to ablate the prostate tissue. Methods associated with use of the prostate therapy system are also covered.
SYSTEMS AND METHODS FOR PLANNING AND PERFORMING IMAGE FREE IMPLANT REVISION SURGERY
Systems and methods for planning and performing image free implant revision surgery are discussed. For example, a method for generating a revision plan can include collecting pre-defined parameters characterizing a target bone, generating a 3D model, collecting a plurality of surface points, and generating a reshaped 3D model. Generating the 3D model of the target bone can be based on a first portion of the pre-defined parameters. Generating the reshaped 3D model can be done based on the plurality of surface points collected from a portion of the surface of the target bone.
ULTRASOUND GUIDED OPENING OF BLOOD-BRAIN BARRIER
An ultrasound treatment system operable to deliver ultrasound energy to a patient's brain, the system comprises a treatment ultrasound transducer comprising a plurality of treatment elements, the treatment ultrasound transducer locatable to deliver ultrasound into the head of the patient. The system further comprises a data store, one or more position sensors configured to detect relative movement between the head of the patient and the treatment ultrasound transducer, and a data processor.
SYSTEMS AND METHODS FOR A TRIPLE IMAGING HYBRID PROBE
A hybrid vision device is provided. The hybrid vision device comprises: an articulating elongate member comprising a proximal end and a distal end, and a positional sensor is located at the distal end of the articulating elongate member; and a multimodal sensing probe removably coupled to the articulating elongate member, and the multimodal sensing probe comprises an ultrasound transducer and a camera located at a distal portion of the multimodal sensing probe.
SYSTEM AND METHOD FOR VERIFICATION OF LOCATION DURING SURGERY
A verification instrument configured to verify the location of a surgical end-effector, including: a body; a navigation element disposed and configured to represent a spatial location of the body; a first clip extending from the body configured to clip onto a tool; a length measurement portion disposed at a first angle from the body, wherein the length measurement portion is configured to contact a tool tip when the first clip is clipped onto the tool.
Simulated bone or tissue manipulation
The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined. The desired relationship between markers may then be programmed into, for example, the detection device. Next, actual physical reduction and/or manipulation of the bone may begin. During the manipulation procedure, the orientation of the markers may be continuously monitored and when the markers substantially align with the virtual or simulated orientation of the markers in the desired restored orientation, an indicator signal is transmitted.
APPARATUS AND METHOD FOR POSITIONING A PATIENT'S BODY AND TRACKING THE PATIENT'S POSITION DURING SURGERY
The disclosed system uses a body shape capturing device for acquiring a patient's body shape and a 3D shape generating device for additively manufacturing a patient receiving device that is at least partially adapted to the patient's body shape or at least partially deviates from the patient's body shape bringing the patient's body into a desired shape so that the outer shape of the patient's body during surgery is identical to the outer shape of the body during shape capturing. The patient receiving device comprises at least one tracker element that is detectable by a detection system. The detection system captures data indicating the at least one tracker element's position and/or orientation during surgery enabling, particularly for surgical operations on or in soft tissues with high flexibly and with no specific natural or artificial landmarks, the surgeon to orientate/navigate in live images from the surgical site.
