    摘要： Techniques and systems for using spectroscopy- and/or image-based sensing with an intravascular blood pump may be provided. The techniques generally include capturing a spectral response to light of a measured tissue and/or blood. Based on the specific needs, the method may include, e.g., determining a type of the measured tissue based on the spectral response, determining if the type of the measured tissue matches a target tissue type, determining a health of the measured tissue based on the spectral response, determining a treatment plan based on the health of the measured tissue, determining a type and/or quantity of components and/or characteristics in the blood, and/or determining a degree of heart recovery based on the type and/or quantity of the components and/or characteristics in the blood.

    摘要： An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface that is configured to engage with the step feature of the expandable sheath. When the step feature engages the catch surface, it resists further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. The nature of the interlocking engagement between the step feature and the catch surface allows the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by simply pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.

    摘要： A multi-channel optical pressure sensor is provided. The multi-channel optical pressure sensor includes at least one LED configured to generate light having a first spectrum and a second spectrum, a plurality of sensors including a first sensor coupled to the at least one LED via at least one first optical fiber and a second sensor coupled to the at least one LED via at least one second optical fiber, and a detector module coupled to first sensor and the second sensor. The detector module comprises at least one lens and an image sensor configured to sense light received from the at least one lens. The multi-channel optical pressure sensor further includes at least one hardware processor configured to determine based, at least in part, on the light sensed by the image sensor, a first pressure measured at the first sensor and a second pressure measured at the second sensor.
