This document relates to the technical field of (and is not limited to): (A) a signal-interface assembly for an electroanatomical mapping system (and/or a method associated therewith); and/or (B) an energy-delivery assembly having a sensor configured to be interfaced to a signal-input section of the signal-interface assembly of an electroanatomical mapping system (and/or a method associated therewith); and/or (C) a synergistic combination of an electroanatomical mapping system, an elongated needle assembly, an energy-delivery assembly and a signal-interface assembly (and/or a method associated therewith).
Known medical devices are configured to facilitate a medical procedure, and help healthcare providers diagnose and/or treat medical conditions of sick patients.
It will be appreciated that there exists a need to mitigate (at least in part) at least one problem associated with the existing (known) electroanatomical mapping systems. After much study of, and experimentation with, existing (known) electroanatomical mapping systems, an understanding (at least in part) of the problem and its solution have been identified (at least in part) and are articulated (at least in part) as follows:
Electroanatomic mapping refers to the acquisition and display (via a display device) of electrical information (signals) pertaining to (derived or sensed from) a biological feature of a patient in combination with spatial localization (a visual map) of a biological feature (this is done, preferably, in situ). An electroanatomical mapping system (EAM system) is configured to provide a display device configured to show (map out and indicate, preferably in real time or near real time, in situ) the three-dimensional anatomy of a biological feature (such as the heart, etc.) of the patient.
It is known that electroanatomical mapping systems may utilize magnetic sensors and/or electrical impedance sensors for generating anatomical maps. Moreover, known transcatheter interventional procedures are utilized for the treatment of a biological feature (such as the left side of the heart) of the patient. For instance, a known procedure among these is the pulmonary vein isolation (PVI) procedure that utilizes an ablation catheter by way of selective application (emission) of radio-frequency energy to a desired portion of the biological feature (such as, a biological wall, etc.). The known PVI procedure may be executed (performed) with assistance from an electroanatomical mapping system configured to visualize both the left atrium (of the heart) and the ablation catheter (preferably, this is done simultaneously and in situ). While under visualization (via the display device of the electroanatomical mapping system), a medical device (which transports the ablation catheter) may be maneuvered and/or navigated (preferably in situ) in such a way that the ablation catheter may be maneuvered to a desired biological feature (or a biological site) of the patient; once the desired biological site is located (by identification via the display device), and the ablation catheter is suitably positioned proximate to (or in contact with) the desired biological site (as indicated by the display device), radio-frequency ablation may be activated (via the ablation catheter) for formation of a desired lesion at the desired biological site.
It may be desirable to accomplish a procedure with less time and/or with more certainty, thereby reducing, at least in part, labor costs, operating room time, etc., associated with executing the procedure.
It may be desirable to provide, for the electroanatomical mapping system, a medical sheath assembly (which is steerable within the patient) configured to improve the procedural workflow of a procedure, such as the known PVI procedure, by allowing a medical device (such as a medical sheath assembly, etc.) to be visualized (in situ) along with an ablation device (such as an ablation catheter, etc.) via the display device of the electroanatomical mapping system.
Before an ablation procedure may be carried out, a transseptal puncture may be required to access the left atrium of the heart. This portion of the procedure may be very difficult to be properly, and confidently, visualized using the display device of the electroanatomical mapping system.
It may be desirable to provide, to users (such as electrophysiologists), an apparatus configured to enable visualization of a radio-frequency transseptal puncture needle by the electroanatomical mapping system.
It may be desirable to provide, for a procedure using energy puncturing, a signal switch assembly (an electrical switch box) configured to convey information (such as voltage measurements, etc.) from at least one medical device (such as, a combination of an ablation catheter and/or a medical sheath assembly) to the electroanatomical mapping system.
For instance, electrophysiologists may rely on a mix of ultrasound, such as, Intracardiac Echocardiography (ICE) and/or Transesophageal Echocardiography (TEE) and fluoroscopy to perform the transseptal puncture (preferably, in situ); these types of equipment may be, disadvantageously, very expensive to own, maintain and/or operate.
It may be desirable to perform the transseptal puncture by utilizing the electroanatomical mapping system. In this manner, the user may, advantageously, receive less (preferably no) or limited x-ray radiation from fluoroscopy, which may be a high priority; moreover, significant capital cost might be avoiding ultrasound technologies altogether.
It may be desirable to provide a steerable sheath assembly with sensors (such as electrodes) using the electroanatomical mapping system. It will be appreciated that a device may be needed for various sensor combinations deployed on the medical devices.
It may be desirable to share sensors of a combination of medical devices (such as a sheath assembly, an energy puncture device, etc.) for visualization of the medical devices via the display device of the electroanatomical mapping system.
It may be desirable to provide electroanatomic mapping based on the acquisition and display (via a display device) of electrical information (signals) pertaining to (derived or sensed from) a biological feature of a patient in combination with spatial localization (a visual map) of the biological feature along with at least one sensor (or two or more sensors) associated with at least one medical assembly such as a catheter (or two or more medical assemblies); this is done, preferably, in situ (during a procedure).
To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a major aspect) an apparatus. The apparatus is for use with an electroanatomical mapping system, an elongated needle assembly (having a distal energy emitter configured to be detectable by the electroanatomical mapping system), an energy-delivery assembly (having at least one sensor configured to receive, at least in part, the distal energy emitter of the elongated needle assembly; this is done in such a way that the distal energy emitter and the sensor are movable relative to each other). The apparatus includes and is not limited to a signal-interface assembly including a signal-input section. The signal-input section is configured to be signal connectable to the sensor of the energy-delivery assembly. The signal-interface assembly also includes a signal-output section configured to be signal connectable to an input section of the electroanatomical mapping system. The electroanatomical mapping system is configured to display, via a display device, a spatial positioning of the sensor of the energy-delivery assembly along with the distal energy emitter (of the elongated needle assembly); this is done, preferably, after: (A) the signal-input section, in use, is signal connected to the sensor of the energy-delivery assembly; and (B) the signal-output section, in use, is signal connected to the input section of the electroanatomical mapping system.

The following is offered as further description of the embodiments, in which any one or more of any technical feature (described in the detailed description, the summary and the claims) may be combinable with any other one or more of any technical feature (described in the detailed description, the summary and the claims). It is understood that each claim in the claims section is an open ended claim unless stated otherwise. Unless otherwise specified, relational terms used in these specifications should be construed to include certain tolerances that the person skilled in the art would recognize as providing equivalent functionality. By way of example, the term perpendicular is not necessarily limited to 90.0 degrees, and may include a variation thereof that the person skilled in the art would recognize as providing equivalent functionality for the purposes described for the relevant member or element. Terms such as “about” and “substantially”, in the context of configuration, relate generally to disposition, location, or configuration that are either exact or sufficiently close to the location, disposition, or configuration of the relevant element to preserve operability of the element within the disclosure which does not materially modify the disclosure. Similarly, unless specifically made clear from its context, numerical values should be construed to include certain tolerances that the person skilled in the art would recognize as having negligible importance as they do not materially change the operability of the disclosure. It will be appreciated that the description and/or drawings identify and describe embodiments of the apparatus (either explicitly or inherently). The apparatus may include any suitable combination and/or permutation of the technical features as identified in the detailed description, as may be required and/or desired to suit a particular technical purpose and/or technical function. It will be appreciated that, where possible and suitable, any one or more of the technical features of the apparatus may be combined with any other one or more of the technical features of the apparatus (in any combination and/or permutation). It will be appreciated that persons skilled in the art would know that the technical features of each embodiment may be deployed (where possible) in other embodiments even if not expressly stated as such above. It will be appreciated that persons skilled in the art would know that other options may be possible for the configuration of the components of the apparatus to adjust to manufacturing requirements and still remain within the scope as described in at least one or more of the claims. This written description provides embodiments, including the best mode, and also enables the person skilled in the art to make and use the embodiments. The patentable scope may be defined by the claims. The written description and/or drawings may help to understand the scope of the claims. It is believed that all the crucial aspects of the disclosed subject matter have been provided in this document. It is understood, for this document, that the word “includes” is equivalent to the word “comprising” in that both words are used to signify an open-ended listing of assemblies, components, parts, etc. The term “comprising”, which is synonymous with the terms “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. Comprising (comprised of) is an “open” phrase and allows coverage of technologies that employ additional, unrecited elements. When used in a claim, the word “comprising” is the transitory verb (transitional term) that separates the preamble of the claim from the technical features of the disclosure. The foregoing has outlined the non-limiting embodiments (examples). The description is made for particular non-limiting embodiments (examples). It is understood that the non-limiting embodiments are merely illustrative as examples.
