Systems and methods for visualizing navigation of a medical device with respect to a target using a live fluoroscopic view. The methods include displaying, in a screen, a three-dimensional (3D) view of a 3D model of a target from the perspective of a medical device tip. The methods also include displaying, in the screen, a live two-dimensional (2D) fluoroscopic view showing a medical device, and displaying a target mark, which corresponds to the 3D model of the target, overlaid on the live 2D fluoroscopic view. The methods may include determining whether the medical device tip is aligned with the target, displaying the target mark in a first color if the medical device tip is aligned with the target, and displaying the target mark in second color different from the first color if the medical device tip is not aligned with the target.

A method for ablating a patient, consisting of ascertaining a CHA.sub.2DS.sub.2-VASc score for the patient and inserting a probe into the patient, so as to contact a pulmonary vein of the patient. The method further includes applying energy via the probe so as to ablate the pulmonary vein until pulmonary vein isolation (PVI) is achieved. When PVI is achieved and the CHA.sub.2DS.sub.2-VASc score is less than a preset value, ablation of the pulmonary vein is ceased. When PVI is achieved and the CHA.sub.2DS.sub.2-VASc score is greater than or equal to the preset value, energy is applied to perform a further ablation.

A medical tool includes a handle, a tubular member, and a bendable shape memory element (SME). The tubular member is attached to and extends from the handle and is configured to be inserted into an orifice of a patient. The tubular member has a distal-end section that is configured to be bent so as to perform a medical procedure in the orifice. The bendable shape memory element (SME) is coupled to the distal-end section of the tubular member, wherein the SME is configured to straighten when heated into a pre-formed shape, thereby straightening the distal-end section.

Provided are systems and methods for displaying an estimated location of an instrument. In one aspect, the method includes determining a first location of the instrument based on first location data generated by a set of one or more location sensors for the instrument, the first location data corresponding to a first time period, and after the first time period, receiving a user command to move the instrument during a second time period. The method also includes estimating a second location of the instrument based on the first location and the received user command, the estimated second location corresponding to the second time period, and confirming the estimated second location based on second location data generated by the set of location sensors. The method further includes causing the estimated second location to be displayed prior to the confirmation of the estimated second location.

A surgical instrument having a first member being engageable with a fastener. A second member includes an expandable portion configured for capturing the fastener. A third member is engageable with the expandable portion to releasably capture the fastener. An actuator connected with the second member and the third member. The actuator includes a threaded inner surface and a threaded coupling member engageable with the threaded inner surface to facilitate axial translation of the second member relative to the third member. Systems, spinal constructs, implants and methods are disclosed.

A system is suggested comprising an optical sensing means and a processing unit. The optical sensing means may include an optical guide with a distal end, wherein the optical guide may be configured to be arranged in a device to be inserted into tissue in a region of interest. The processing unit may be configured to receive information of a region of interest including different tissue types as well as of a path through the tissues, to determine a sequence of tissue types along the path, to determine a tissue type at the distal end of the optical guide based on information received from the optical sensing means, to compare the determined tissue type with the tissue types on the path, to determine possible positions of the distal end of the optical guide on the path based on the comparison of tissue types, and to generate a signal indicative for the possible positions.

A system and method for estimating a pose of an imaging device for one or more images is provided.

A system and method for a procedure that can be performed on any appropriate subject. Procedures can include assembling any appropriate work piece or installing members into a work piece, such as an airframe, autoframe, etc. Regardless of the subject, tracking a substantially small tracking device in a plurality of degrees of freedom is provided. The tracking device can be positioned on or be formed in an instrument to be tracked.

Systems and methods for marking the location and extent of an anatomical region-of-interest, such as a tumor, using magnetic seeds whose position and orientation are measured or otherwise detected using a detection device that includes two or more magnetic sensors are described. One or more magnetic seeds are implanted to mark and define the center and extent of an anatomical region-of-interest and a magnetic sensor-based detector system is used to accurately identify the location of the magnetic seeds.

A system for assessing laxity of a joint of a patient is disclosed. The system comprises a tensioner tool having a substantially rigid portion that may be inserted within the joint to apply a force against a bone surface thereof. The system further comprises a tensioner sock having a flexible body with an opening to receive the tensioner tool and a sensor array disposed on the flexible body. Each sensor of the sensor array is configured to contact the bone surface and detect a pressure when the force is applied against the bone surface. The system further comprises a processor configured to receive the detected pressure from each sensor and calculate the force applied to the bone surface based on the detected pressures.
