  • Publication number: 20150231320
    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.

  • Publication number: 20150119796
    Abstract: The present teachings provide thread attachment mechanisms each having an internal and an external threaded portion. The internal and external threaded portions are configured to engage with each other to form an attachment. The thread attachment mechanism in the present teachings further include an anti-lockup feature. The present teachings further provide a cardiac implant engaged with a delivery catheter devices through a thread attachment mechanism having an anti-lockup feature of the present teachings. In one embodiment, the anti-lockup feature prevents the implant from being overly tightened to the delivery catheter. In another embodiment, the anti-lockup feature allows the implant to be released from the delivery catheter in a predictable and controlled manlier. Another aspect of the present teachings provides methods of using a threaded attaching mechanism of the present teachings to deliver, deploy, and release a cardiac implant.

  • Publication number: 20140323954
    Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include patient line state detector for detecting whether a patient line is primed before it is to be connected to the patient. The patient line state detector can also the ability to detect whether a patient line has been properly mounted for priming. Both patient line presence/absence and fill state can be determined using an optical system, e.g., one that employs a single optical sensor.

  • Publication number: 20140277054
    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: 8752258
    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: 20130281988
    Abstract: The present teachings generally relate a delivery system having an implant retention mechanism. Specifically, the delivery system includes a delivery sheath, a delivery catheter, and a flexible or a rigid implant retention mechanism. The flexible implant retention mechanism includes an implant retention string having a fixed end and a free end where the free end extends from the fixed end, crosses a retention outlet of an implant, and extends proximally through a lumen of the delivery sheath. The rigid implant retention mechanism includes an implant retention wire having a fixed end and a free end where the free end extends from the fixed end, crosses a retention outlet of an implant, and extends proximally through a lumen of the delivery sheath.
