  • Patent number: 11504130
    Abstract: Balloon catheters and methods are provided for selectively occluding blood flow into a right atrium of a patient's heart communicating with an inferior vena cava (IVC) and superior vena cava (SVC). In one embodiment, a catheter includes first and second balloons adjacent one another on a distal end of the catheter shaft. During use, the distal end is introduced into the right atrium and positioned such that the first balloon is located within the right atrium. The first balloon is expanded within the right atrium and the catheter shaft directed such that the expanded first balloon engages at least a portion of the IVC to prevent substantial inflow into the right atrium from the IVC. The second balloon is then expanded to limit inflow into the right atrium from the SVC, and a medical procedure is performed within the patient's body.

  • Patent number: 11419627
    Abstract: The invention discloses a novel vascular punch employing compressive normal force for tissue separation from a targeted vessel. This invention is particularly designed for making a large round hole without massive bleeding in vascular surgery. A clean, non-frayed hole-making guided by the normal force cutting principle is realized using a site-biting punch mechanism. The side-biting vascular punch comprises a U-shaped razor blade cutter, a backstop for receiving the cutter, and a linkage mechanism, forming an aligned line of contact for normal compression force generation and thereby severing tissue out of the targeted vessel.

  • Patent number: 11406417
    Abstract: A device for introduction into a body vessel includes a shaft, a balloon positioned at the distal end of the shaft, a guidewire disposed longitudinally within the shaft to receive a guidewire during use, a balloon disposed at the distal end of the shaft, and longitudinal scoring wires to score a vascular lesion attached to the distal end of the shaft. The scoring wires are disposed over the balloon and disposed within the shaft. The proximal ends are welded or otherwise affixed to a spring mounted in the handle. The balloon expands when fluid is delivered to the balloon through the inflation lumen. This expansion pushes the scoring wires against the vascular lesion. The scoring wires attach to a source of vibrations. The scoring wires are made of a helical coil.

  • Patent number: 11399858
    Abstract: An ultrasonic device may include an electromechanical ultrasonic system having a resonant frequency, the system including a transducer coupled to an ultrasonic blade. A method of driving the blade may include determining a tissue type contacting the blade, setting current delivered to the transducer to achieve a desired blade temperature, and setting a desired period during which the desired temperature is applied to the tissue. The tissue type may be determined by measuring an impedance of the transducer, comparing an impedance measurement data point to a reference data point, and classifying the impedance measurement data point based on a result of the comparison. Alternatively, the tissue type may be determined by applying a drive signal to the transducer, sweeping the frequency of the drive signal from below to above a resonance of the ultrasonic system, measuring and recording impedance/admittance variables, and comparing the measured variables to reference variables.
