Abstract: Optical connection systems including electrical-and-optical connection systems and methods thereof are disclosed. An electrical-and-optical connection system can include an extension tube having a plug and a relay module having a receptacle. The plug can be formed of a metal piece around electrical wires, which, in turn, are around optical-fiber cores that extend along a length of the extension tube. The plug can be configured to pierce through at least a sterile barrier. The relay module can include electrical wires and optical-fiber cores within a housing of the relay module, as well as a receptacle disposed in the housing. The receptacle can be configured to simultaneously accept insertion of the plug therein and establish both electrical and optical connections between the plug and the receptacle from a sterile field to a non-sterile field set up by the sterile barrier. Shape-sensing systems including the optical connection systems are also disclosed.

Abstract: A system, apparatus and method directed to detecting damage to an optical fiber of a medical device. The optical fiber includes one or more core fibers each including a plurality of sensors configured to (i) reflect a light signal based on received incident light, and (ii) alter the reflected light signal for use in determining a physical state of the multi-core optical fiber. The system also includes a console having non-transitory computer-readable medium storing logic that, when executed, causes operations of providing a broadband incident light signal to the multi-core optical fiber, receiving reflected light signals, receiving reflected light signals of different spectral widths of the broadband incident light by one or more of the plurality of sensors, identifying at least one unexpected spectral width or a lack of an expected spectral width, and determining the damage has occurred to the optical fiber based on the identification.

Abstract: Disclosed herein is a system, apparatus and method directed to placing a medical instrument in a vasculature of a patient body, where the medical instrument includes an optical fiber having one or more core fibers. The system also includes a console having non-transitory computer-readable medium storing logic that, when executed, causes operations of providing an incident light signal to the optical fiber, receiving a reflected light signal of the incident light, processing the reflected light signals associated with the optical fiber and determining a location of a distal tip of the medical instrument within the patient body. The medical instrument may be steerable in one of various methods including having a predetermined curvature, a distal tip that is magnetic, magnetized, metallic or ferrous and is steerable by an external magnetic device or a having a variable stiffness at a distal tip.

Abstract: Medical systems and devices include an elongate probe configured for insertion into a patient, where the elongate probe includes an atraumatic tip and where the atraumatic tip can include one or more of a loop, a curl, coil, a flexible distal region, and a steerable distal region. The distal region can be configured to transition away from a first shape toward a second shape upon insertion of the elongate probe within the patient. The optical fiber can include sensing core fibers configured to facilitate a determination of a physical state of the elongate probe. The elongate probe can also be configured to project illuminating light away from a distal end and receive imaging light at the distal end. The elongate probe can include a catheter.

Abstract: A medical ultrasound system that includes an ultrasound probe and one of number of optional accessories attached to the ultrasound probe. The accessory exchanges data with the probe and receives power from the probe. The accessory includes processors and logic that governs it operation thereby adding functionality to the probe. The accessory receives input and provides output via any of a number of communication mechanisms, i.e., wireless, electrical, optical, RFID, IR, and the like. The accessory adds functionality to the probe, such as fiber optic shape sensing, obtaining electrical signals, obtaining bio-impedance measurements, tracking a needle, and determining the orientation of the probe. The accessory may include a needle guide, a triphalangeal support structure, or an acoustically transparent cap.

Abstract: System and methods for disinfecting ultrasound probes including a disinfection module operably and physically coupled with an ultrasound-imaging system including an ultrasound probe. The disinfection module is configured to expose the external surface of the ultrasound probe to UV light to define a high-level disinfection process. Sensors determine when the ultrasound probe is disposed within a disinfecting cavity of the disinfection module and logic governs the operation of UV light sources. Logic determines a contamination level of the probe and defines an appropriate disinfection level. Exposing the probe to hydrogen peroxide is an alternative to the UV light. Logic may activate the high-level disinfection process upon placement of the probe within the cavity.

Abstract: A shape-sensing system can include an optical-fiber probe and a vibration-assisted torsion-management means for managing torsion in the optical-fiber probe. The optical-fiber probe can be configured to be removably disposed in an elongate medical device. The optical-fiber probe can include an inner construction and an outer construction over the inner construction but detached therefrom over a majority of the optical-fiber probe. The inner construction can include one or more optical-fiber cores disposed in a cladding. The outer construction can include a mechanical layer. The vibration-assisted torsion-management means can be operably coupled to the optical-fiber probe for vibrating either the inner construction or the outer construction of the optical-fiber probe relative to the other, which mitigates or eliminates any optical signal-distorting torsion in the inner construction of the optical-fiber probe. A method of the shape-sensing system can include managing torsion of the optical-fiber probe with the vibration-assisted torsion-management means.

For example, a system can include a console and a display screen optionally integrated into the console. The console can include one or more processors and memory. The memory can include instructions configured to instantiate one or more processes when executed by the one-or-more processors for the automatic determination of the one-or-more medical devices for vascular access in accordance with a plurality of data inputs, various operating parameters, historical data, or a combination thereof. The automatic determination of the one-or-more medical devices can use at least logic, algorithms, machine learning including a machine-learning model trained with the historical data, artificial intelligence, or a combination thereof. The display screen can be configured to display the one-or-more medical devices recommended for vascular access.

Abstract: A medical device guide system that includes an ultrasound probe is configured for imaging portions of a patient's body. The system is configured to automatically position and/or orient a needle guide with respect to the probe in accordance with a desired needle trajectory with respect to the target blood vessel. The system includes one or more of a blood vessel detection system, a probe orientation system and/or a needle tracking system to facilitate automatically positioning of the needle guide. Some needle guides include multiple channels that define different angles of needle insertion. The needle guide is selectively coupled with a needle guide connector that is operatively coupled with the probe via an electro-mechanical mechanism.
