  • COLLAPSIBLE CATHETER
    Publication number: 20210093836
    Abstract: An intravascular system includes an introducer sheath with fixed-diameter lumen, a medical device, and a catheter with a proximal end and a distal end coupled to the first medical device. When the catheter is positioned within the introducer sheath, an annular gap is formed between an exterior circumference of the catheter and an inner circumference of the lumen. The catheter is configured to take different dimensional configurations, such that the sizes of the catheter and the annular gap are variable. The variability of the size of the catheter allows another medical device to pass through the annular gap within the lumen. The catheter may change configurations passively as the second medical device is passed adjacently or by an active mechanism under a physician's control.

  • Systems and methods for controlling a heart pump to minimize myocardial oxygen consumption
    Patent number: 10960118
    Abstract: Various systems, devices, and methods are disclosed herein for treating acute myocardial infarction (AMI) patients using a heart pump controlled in a manner that maximizes mechanical unloading of the left ventricle in the presence of cardiovascular instability and minimizes myocardial oxygen consumption (MVO2) and consequentially infarct size to prevent the development of subsequent heart failure. In a closed feedback system, the system can include a sensor configured to generate an output used to measure or calculate a left ventricular systolic pressure (LSVP) within the left ventricle of a heart and a controller coupled to a heart pump. The controller can be configured to measure or calculate the LVSP based on the output of the sensor and to control an operation of the heart pump to maximize mechanical unloading of the left ventricle based on the measured or calculated LVSP.

  • Guidewire access sleeve
    Patent number: 10953205
    Abstract: An access sleeve can be attached to a medical device having first and second ends, the first end being positioned inside of a patient and the second end being positioned external to a patient. The access sleeve can include a tubular sleeve body having first and second open ends that define a first lumen extending along a longitudinal axis of the sleeve body. An opening in the sleeve body can connect the first lumen to an outer surface of the sleeve body. The access sleeve can be selectively attached to the medical device (e.g. catheter of a heart pump) and inserted into the access site when the medical device is positioned in the patient. The access sleeve can maintain vascular access to a patient's access site such as an arteriotomy and can be removed without disturbing the position of the medical device.

  • DETERMINATION OF CARDIAC PARAMETERS FOR MODULATION OF BLOOD PUMP SUPPORT
    Publication number: 20210038793
    Abstract: The systems, devices, and methods presented herein use a blood pump to obtain measurements of cardiac function. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as aortic pressure or motor current, then calculate and display one or more cardiac parameters and heart function parameters, such as left ventricular pressure, left ventricular end diastolic pressure, or cardiac power output. These parameters provide valuable information to a user regarding current cardiac function, as well as positioning and function of the blood pump. In some embodiments, the system can act as a diagnostic and therapeutic tool.

  • Thermoform cannula with variable cannula body stiffness
    Patent number: 10849653
    Abstract: A cannula supporting a percutaneous pump can include a proximal section with a first flexural modulus. The cannula can include one or more distal sections with a flexural modulus that is different than the first flexural modulus. The material and its arrangement along the length of the cannula can be selected so as to influence bending properties. This can, for example, allow efficient positioning of the cannula in a desired location without displacing the guidewire.

  • Intelligent image segmentation prior to optical character recognition (OCR)
    Patent number: 10824898
    Abstract: A medical device monitoring system and method extract information from screen images from medical device controllers, with a single OCR process invocation per screen image, despite critical information appearing in different screen locations, depending on which medical device controller's screen image is processed. For example, different software versions of the medical device controllers might display the same type of information in different screen locations. Copies of the critical screen information, one copy from each different screen location, are made in a mosaic image, and then the mosaic image is OCR processed to produce text results. Text is selectively extracted from the OCR text results, depending on contents of a selector field on the screen image, such as a software version number or a heart pump model identifier.

  • Corkscrew shape for right-sided cardiac device
    Patent number: 10722625
    Abstract: A catheter includes a catheter body, a pump assembly and a cannula. The pump assembly can be disposed at a distal end of the catheter body and has a distal portion. The cannula can be coupled to the distal end portion of the pump assembly and can include a proximal cannula portion and a distal cannula portion. The distal cannula portion has an approximately helical shape which can allow the cannula to be inserted into a patient's right heart and pump blood therethrough. In certain implementations, the distal tip of the helical shape has a slight bias relative to the main helix to further facilitate delivery of the device. In certain applications this bias is toward the central axis of the helix.

  • Introducer sheath having a multi-layer hub
    Patent number: 10709476
    Abstract: An introducer assembly includes an elongate sheath sized for insertion into a blood vessel of a patient and a hub. The hub can be coupled to a proximal portion of the sheath and can include a first hub portion and a second hub portion. The hub can include various features to facilitate breaking apart or separating the introducer assembly from a patient. For example, the first hub portion can have a first notch which can facilitate breaking, splitting, or fracturing the hub. The second hub portion can partially surround the first hub portion and can include two wings and an opening disposed above the first notch. The first hub portion can be formed from a first material and second hub portion can be formed from a second material. In some embodiments, the second material can be stiffer than the first material to facilitate fracturing the hub.
