摘要： 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.

摘要： An apparatus includes an interface and a processor. The interface is configured to receive one or more magnetic-positioning signals from one or more position sensors coupled to one or more body-surface patches attached to a body of a patient, the magnetic-positioning signals indicative of respective positions of the position sensors. The processor is configured to (i) detect an inadvertent stimulation of a phrenic nerve of the patient, which occurs due to cardiac pacing applied by an intra-cardiac electrode in a heart of the patient, (ii) estimate, based on the magnetic-positioning signals, a motion of one or more of the body-surface patches occurring during the detected stimulation of the phrenic nerve, (iii) estimate, based on the estimated motion of the body-surface patches, a distance between the pacing electrode and the phrenic nerve, and (iv) send an output derived from the estimated distance to the output device.

摘要： An electronic device is disclosed. The electronic device comprise an elongate electrical connector that is configured to connect to an integrated device package. The elongate electrical connector can comprise an elongate flexible substrate. The elongate flexible substrate has a proximal portion and a distal portion spaced from the proximal portion by a length along a longitudinal axis. The elongate flexible substrate has a width along an axis transverse to the longitudinal axis. The elongate flexible substrate defines an elongation ratio of the length to the width. The elongation ratio is at least 100:1. The elongate electrical connector can be connected to a bobbin. The elongate electrical connector can be configured to unspool from the bobbin.

摘要： A catheter has single axis sensors mounted directly along a portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are on a linear or nonlinear single axis sensor (SAS) assembly. The catheter includes a catheter body and a distal 2D or 3D configuration provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. The magnetic-based sensor assembly may include at least one coil member wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system. The joint region provides strain relief adaptations to the at least one coil member and the respective cable member from detaching.

摘要： Example methods and systems may be used intraoperatively to help surgeons perform accurate and replicable surgeries, such as knee arthroplasty surgeries. An example system combines real time measurement and tracking components with functionality to compile data collected by the hardware to register a bone of a patient, calculate an axis (e.g., mechanical axis) of the leg of the patient, assist a surgeon in placing cut guides, and verify a placement of an inserted prosthesis.

摘要： Devices detect and assist in the avoidance of blood vessels during a surgical procedure—to avoid rupturing these blood vessels. Devices may be any penetration sensor device (such as a dilator sensor device, hollow needle sensor device, or trocar sensor device) that penetrates the skin and subcutaneous layers to reach a target location inside the body. The device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the device can be determined while the device travels towards the target location for surgery.

摘要： A device includes a syringe, which has a tip, plunger, and barrel containing a fluid. The device also includes a needle electrode coupled to the tip of the syringe, a release component, and a control component configured to receive electrical measurements made by the needle electrode, determine impedance values from the electrical measurements, and identify a target tissue based on the impedance values. In response to the identification, the control component generates instructions to reposition a release component. A method includes receiving electrical measurements from a needle electrode, determining impedance values based on the electrical measurements. A target tissue is identified based on the impedance values, and a release component is repositioned in response. An article of manufacture includes a needle electrode and a microprocessor configured to receive electrical measurements, determine impedance values, identify a target tissue based on the impedance values, and generate instructions to reposition a release component.
