Abstract: A sterile bag for covering medical equipment comprises: a barrier section, a flexible body section, and an attaching section. The flexible body section has a tubular shape extending from a proximal end to a distal end thereof, and an outer surface, an inner surface, and an open end. The barrier section is coupled to the proximal end, and the attaching section is formed at the distal end of the flexible body section. The barrier section is a rigid or semirigid component which attaches the sterile bag to a sterile component or to an unsterile component of the medical equipment in a pleaded or folded state. The flexible body section is configured to be deployed over the unsterile component so as to enclose within the inner surface thereof the unsterile component. The unsterile component is connectable to the sterile component through the central opening of the barrier section.

Abstract: A method for reproducing a lumen curve to a given tolerance in at least one image in optical coherence tomography (OCT). Examples of applications include imaging, evaluating and diagnosing biological objects, such as, but not limited to, cardio applications, and being obtained via one or more optical instruments, such as, but not limited to, catheters. The method may include obtaining a set of original points of the curve that correspond to measurements from an optical imaging device. Filtering the set of original points using at least one criteria to obtain a subset of original points. The method may also include determining if the subset of original points is less than a predetermined threshold and adjusting the at least one criteria to increase an amount of original points included in the subset of original points when it is determined that the subset of original points is less than the predetermined threshold.

Abstract: A method for processing an intravascular image including a plurality of image frames acquired during a pullback of an imaging catheter inserted into a vessel. The method includes obtaining positions of lumen borders detected in the intravascular image and positions of stent-struts detected in the intravascular image. Determining, at different positions in a range, a stent expansion value of the stent implanted in the vessel, based on the first information and the second information, wherein each image frame from image frames in which stent-struts are detected corresponds to a different position along the range. The method may also include displaying an image including positions of lumen borders and positions of the stent-struts detected and a first indicator indicating a level along the range, of the stent expansion value, with the image.

Abstract: System and methods for out-of-band pairing sterile medical device with non-sterile devices without compromising sterility thereof. A system includes a sterile medical device; a non-sterile computing device; at least one near field communication (NFC) tag; and a sterile packaging enclosing the sterile medical device. In one example, a sterile percutaneous needle guidance device needs to pair and communicate with a non-sterile computer. The sterile device has an NFC tag embedded in the sterile device and an NFC tag embedded in the sterile packaging. The two NFC tags include identification information duplicate of each other. Before opening the sterile packaging either NFC tag can be scanned with the non-sterile device to initiate wireless pairing. If the sterile package is opened before pairing, the NFC tag contained in the packaging can be brought out of the sterile field and scanned with the non-sterile computer thus preserving the sterility of the sterile device.

Abstract: A method for visualization guidance of device-to-image registration includes acquiring image data of a patient, generating a 3D model of the anatomy of the patient based on the image data, performing initial registration between image space and device space, advancing a device into a structure, tracking trajectory of the device in relation to the model, determining divergence between the device trajectory and the model, and effecting correction to the model or the device trajectory to minimize the divergence.
