  • Publication number: 20220249755
    Abstract: A medical infusion fluid handling system, such as an automated peritoneal dialysis system, may be arranged to de-cap and connect one or more lines (such as solution lines) with one or more spikes or other connection ports on a fluid handling cassette. This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the one or more lines and the one or more spikes. For example, the automated peritoneal dialysis system may include a carriage arranged to receive the one or more lines each having a connector end and a cap. The carriage may move along a first direction so as to move the connector ends of the one or more lines along the first direction, and a cap stripper may be arranged to engage with the caps on the solution lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

  • Patent number: 11135410
    Abstract: The present teachings provide a device to change the pressure in a chamber of a heart and methods of making and using thereof. One aspect of the present teachings provides a device comprising a frame (for example, a metallic frame) and a scaffold. The frame of the device has a distal flange portion, a shunt portion, and a proximal flange portion. The distal and proximal flange portions can align with the shunt portion and form an elongated first profile. At least one of the distal and proximal flange portions can bend radially away from the shunt portion to form a flange like profile. The scaffold includes one or more than covering layers and encloses parts of the frame or the entire frame. The covering layer provides a barrier between the biological matter and the frame of the device.

  • Patent number: 10932786
    Abstract: The present teachings provide a device to close a ductus arteriosus percutaneously. One aspect of the present teachings provides a device comprising at least one flange portion configured to be positioned against a vascular wall outside one end of a ductus arteriosus, and a body portion configured to be positioned inside the ductus arteriosus. The body portion of the device has a length adjustable in order for the device to fit inside patients with various ductus arteriosus lengths. The at least one flange portion of the device has pivotability in order for at least one flange to deflect from the longitudinal axis of the body portion so that the deployed device can be positioned at a treatment site allowing the discs to sit flat against the vascular tissue to promote closure while avoiding disruption of flow within the pulmonary artery and aorta or applying excess pressure to the surrounding vascular tissue.

  • Patent number: 10610210
    Abstract: The present disclosure relates to devices and methods for implanting a prosthesis into a heart of a mammal, such as a person. The disclosure includes a prosthesis that acts as a pressure vent between the left and right atria of the heart. The disclosure also includes a mounting tool for mounting the prosthesis onto a loading tool, the loading tool useful for loading the prosthesis onto a device for delivering the prosthesis into the patient's heart. Control devices and methods for using these devices are also disclosed. The intracardiac pressure vents disclosed allow sufficient flow from the left atrium to the right atrium to relieve elevated left atrial pressure and resulting patient symptoms. The devices also limit the amount of flow from the right atrium to the left atrium to minimize the potential for thrombi or other embolic material from entering arterial circulation.

  • Publication number: 20190336163
    Abstract: The present teachings provide devices for puncturing the atrial septum percutaneously. Specifically, one aspect of the present teachings provides a trans-septal puncturing device comprising one or more of a locating element, a stabilizing element, a puncturing element, a safety element, and optionally a monitoring element, each of which is disposed in a lumen of a sheath. The locating element and the stabilizing element locate a desired puncture site and stabilize the trans-septal puncturing device at or near the site. The puncturing element of the trans-septal puncturing device has a limited puncturing distance due in certain instances to the safety element. The present teachings provide methods of using such device for percutaneously locating a fossa ovalis, stabilizing such device at the fossa ovalis, and piercing tissue across the fossa ovalis.

  • Patent number: 10463477
    Abstract: The present teachings provide devices to change the pressure in a chamber of a heart and methods of making and using thereof. One aspect of the present teachings provides a device comprising a distal portion, a middle portion, and a proximal portion. The distal portion and proximal portion of the device are configured to be deployed inside the left and right atrium respectively with a minimum contact with the septal tissue. The middle portion of the device is configured to secure the device across an aperture on the atrial septum. The device further includes at least one retrieval portion with a plurality of struts. The distal end of the struts is connected with a proximal end of the proximal portions. The proximal end of the struts come together at a location near the axial center of the device. The radial expansion of the proximal portion will lead to the radially outward movement of the struts. And a radially inward movement of the struts will cause the proximal portion of the device to collapse radially.

  • Patent number: 10188375
    Abstract: Several unique intra-cardiac pressure vents, placement catheters, methods of placement and methods of treating heart failure are presented. The intra-cardiac pressure vents presented remain partially open under normal intra-cardiac pressures to allow sufficient flow from the left atrium to the right atrium to enable the relief of elevated left atrial pressure and resulting patient symptoms, and also limit the amount of flow from the right atrium to the left atrium by closing when the pressure in the right atrium exceeds the pressure in the left atrium by a predetermined amount.
