Abstract: Disclosed is a method for assisting a surgeon in bringing a medical implement having a marker to a target location within a body of a patient. According to some embodiments, the method includes receiving a first image of the medical implement on its way to the target location in the body of the patient; processing the image to obtain an enhanced image showing at least said marker; and providing the original image and the enhanced image for display to the surgeon, wherein the enhanced image is provided for display as an inset on a display of the first image.
Abstract: There is provided a method of treating a patient, comprising: delivering a self-expandable transcatheter heart valve (THV) over a guidewire in a contracted state and within a sheath to a first anatomical location within a heart of the patient, moving the THV relative to the sheath for partially self-expanding a portion of the THV within the first anatomical location, wherein a portion of the THV in the sheath remains in the contracted state and the THV is partially self-expanded, and refraining from moving the partially self-expanded THV, relative to the aortic annulus of the heart.

Abstract: There is provided a computer implemented method of monitoring a guidewire position during a medical procedure, comprising: analyzing a plurality of baseline images captured over a plurality of at least one of heartbeats and breathing cycles, the plurality of baseline images depicting a guidewire in a body cavity, computing according to the analysis, a baseline movement of the guidewire during the at least one of heartbeats and breathing cycles, and monitoring successive images of the guidewire for detecting movement of the guidewire that deviates from the baseline movement.
Abstract: Automatic intraoperative monitoring of new onset conduction disturbances (NOCD) comprising comparison of metric values derived from an ECG signal recording to reference values. An alarm is raised when the comparison result indicates a new onset conduction disorder. Other indications of the comparison may also be presented. Reference values may derive, for example, from a baseline ECG signal recording, and/or from a database of previously observed associations between ECG signals and NOCD. In some embodiments, comparison is also made to threshold values defined by clinical heart block criteria. Baseline and clinical threshold values may define a range used in the comparison. Comparison may combine ranges; for example, using Boolean logic. Comparison and/or alarm triggering is optionally modulated by a database of previously observed associations between non-ECG data and NOCD. Optionally, a user is enabled to select alarm triggering conditions through a user interface.
