  • Publication number: 20240023813
    Abstract: Apparatus, systems and methods for ultrasound and photoacoustic guidance of coronary procedures are disclosed herein. Certain embodiments include a first catheter comprising an ultrasound transceiver, and a second catheter comprising a proximal end and a distal end, with a photoacoustic excitation light transmitter positioned at the distal end of the second catheter. The photoacoustic excitation light transmitter can be configured to emit excitation light in a conical pattern and at a specific pulse duration. The second catheter can be configured to detect photoacoustic signals resulting from the absorption of excitation light emitted by the photoacoustic excitation light transmitter.

  • Patent number: 10512482
    Abstract: In some embodiments, a system for scoring human endocardium tissue may include a first conduit and an activation system. The first conduit may include a first opening, a second opening, and a cutting device. The first opening may be positioned at a proximal end of the first conduit.

  • Patent number: 10433861
    Abstract: In some embodiments, a method of ameliorating diastolic dysfunction may include positioning at least a distal end of a system for cutting a trabeculae carneae in a left ventricle of a human heart. The system may include an elongated member, a grip, an engaging portion, and a cutting device. A second end of the engaging portion may turn in upon the engaging portion towards a first end of the engaging portion while still allowing trabeculae carneae to enter through an opening between the first and second ends. The cutting device may be positioned within an inner diameter of the engaging portion. The method may include positioning at least one trabeculae carneae in the inner diameter of the engaging portion. The method may include severing the at least one trabeculae carneae. The method may include increasing left ventricular compliance of the human heart.
