  • Patent number: 10765791
    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.

  • 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.

  • 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.

  • Patent number: 10512537
    Abstract: A polymeric heart valve is disclosed which includes a valve body having a central axis and including a conduit extending along the central axis from an inflow end to an outflow end; and at least three flexible leaflets extending from the body into the conduit, each of the leaflets defining an attachment curve with the body. Respective pairs of leaflets each define a commissure located proximal the body. The at least three leaflets define a partially open position at rest, a fully open position deflecting away from the central axis during forward blood flow along a direction from the inflow end to the outflow end, and a closed position deflecting toward the central axis during reverse blood flow along a direction from the outflow end to the inflow end.

  • Patent number: 10478542
    Abstract: An intravascular heart pump assembly can include a rotor with at least one impeller blade, and a cannula. The present application describes various cannulas that can be manufactured from multiple layers of material to improve flexibility, manufacturability, and durability without increasing an outer diameter of the cannula. In one embodiment, the cannula includes an inflow section having a sheet formed of a shape memory material embedded within a polymer and having at least one lateral hole or aperture in the inflow section. The at least one lateral hole is defined by a first hole in the sheet and a second hole in the outer polymer layer of the cannula. The first hole and the second hole overlap so that blood can enter the cannula through the holes.

  • Patent number: 10342906
    Abstract: A blood pump assembly can include various components such as a housing and a sensor configured to detect one or more characteristics of the blood. In some embodiments, the sensor can be coupled to the housing and can include a sensor membrane configured to deflect in response to a change in a blood parameter (e.g., pressure). The blood pump assembly can include a shield that covers at least a portion of the sensor membrane so as to protect the sensor from damage when the blood pump assembly is inserted through an introducer and navigated through the patient's vasculature and/or when the blood pump assembly is inserted into the heart in a surgical procedure. One or more protective layers can be deposited over the sensor membrane to prevent the sensor membrane from being dissolved through interactions with the patient's blood.

  • Patent number: 10300249
    Abstract: A guidewire for backloading and inserting a percutaneous pump affixed to a cannula includes a proximal section made of a first material, with a first diameter, a rounded proximal end, and a distal end. The guidewire also includes a distal section made of a second material, with a second diameter which is greater than the first diameter, a distal end, and a proximal end abutting the distal end of the proximal section. The first material of the proximal section is selected to be softer than a material of the percutaneous pump to reduce damage to the pump during backloading. The distal section of the guidewire is configured to be stiffer than the proximal section to insert the percutaneous pump in a desired location without damaging the guidewire.

  • Patent number: 10238782
    Abstract: A catheter apparatus can include a first magnet coupled to a catheter and a second magnet configured to couple to a patient's skin. When the catheter and the first magnet are positioned within a patient's body, the second magnet can exert a magnetic force on the first magnet that stabilizes the catheter relative to the second magnet. The second magnet can be directly attached to the patient's skin or secondary devices such as straps can be used to place the second magnet in a fixed position relative to the patient's body. In some implementations, a plurality of magnets can facilitate holding the catheter in a substantially fixed position within the patient.
