  • Publication number: 20240081998
    Abstract: The present disclosure relates generally to the field of medical devices for treating heart disease. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. A system for delivering a chordae tendineae into a heart may include a delivery catheter. A clamp catheter may be configured to translate through the delivery catheter. A spreader may be disposed on the clamp catheter. A first clamp may be at least partially contained in the spreader in a closed configuration and may be attached to the chordae tendineae. An anchor catheter may be configured to translate through the delivery catheter and may have an anchor attached to the chordae tendineae. A sheath may be extended over the anchor catheter and anchor and may be configured to restrain an arm of the anchor.

  • Publication number: 20240071593
    Abstract: Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

  • Patent number: 11728777
    Abstract: Disclosed is an RF (Radio Frequency) power source having a power supply configured to convert an AC (Alternating Current) voltage at a power supply input to a second voltage at a power supply output, and an RF generator configured to receive the second voltage at an RF generator input and to use the second voltage to produce an output RF signal at an RF generator output. According to an embodiment of the disclosure, the power supply performs the voltage conversion without galvanic isolation between the power supply input and the power supply output, which can increase energy efficiency while reducing complexity and cost as well. Instead, the RF generator is provided with galvanic isolation between the RF generator input and the RF generator output, which can be sufficient for achieving galvanic isolation between the power supply input and the RF generator output for safety reasons.

  • Patent number: 11700161
    Abstract: A system for peak-to-average-power ratio (PAPR) reduction of a frequency shifted plurality of digital broadcast signals taking into account the combined signal peaks in order to transmit the signals more efficiently in a single broadcast transmission system. The PAPR algorithm takes into account a rotating constellation phase offset for the shifted signals corresponding to the amount of applied frequency shift. In the case of a dual sideband In-Band-On-Channel (IBOC) signal typically used in conjunction with an FM carrier in the center, the sidebands can be interleaved to create a new IBOC signal definition and take the place of the FM carrier for an all-digital transmission that is backward compatible with IBOC receivers allowing for a gradual migration to all digital broadcasting.

  • Patent number: 11543403
    Abstract: Aspects of the present disclosure include a titration probe that mitigate the occurrences of titration probe clots. A bar such as segment of music wire, is extended across the tip of a titration probe and attached at both ends to the titration probe. The bar is configured to catch clots and prevent the clots from being collected along with a blood sample to be analyzed. The bar effectively reduces the cross sectional area of the titration probe tip.
