  • Patent number: 10729835
    Abstract: A monitoring device operates on a pressure signal from a blood processing apparatus which has an extracorporeal blood circuit for pumping blood through a dialyzer, and a treatment fluid supply system for pumping a treatment fluid through the dialyzer. The monitoring device has a first input block for obtaining a first pressure signal, and a second input block for obtaining a second pressure signal. An emulation block generates, as a function of the second pressure signal, an emulated first pressure signal which emulates a concurrent signal response of the first pressure sensor, and a filtering block generates a filtered signal as a function of the first pressure signal and the emulated first pressure signal, so as to suppress, in the filtered signal compared to the first pressure signal, signal interferences originating from the treatment fluid supply system. A pulse detection block processes the filtered signal for detection of subject pulses.

    Abstract: A device for treatment of mitral annulus dilatation comprises an elongate body having two states. In a first of these states the elongate body is insertable into the coronary sinus and has a shape adapting to the shape of the coronary sinus. When positioned in the coronary sinus, the elongate body is transferable to the second state assuming a reduced radius of curvature, whereby the radius of curvature of the coronary sinus and the radius of curvature as well as the circumference of the mitral annulus is reduced.

  • Publication number: 20070073391
    Abstract: A system and method is provided for treating a mitral valve. The method preferably includes advancing a guide catheter to an ostium of the coronary sinus and advancing a delivery catheter containing a medical implant through the guide catheter and into the coronary sinus. The delivery catheter has an inner member on which the medical implant is held and an outer sheath which is retractable for deploying and releasing the medical implant. In one embodiment, the medical implant has proximal and distal anchors and a bridge containing resorbable material. The inner member may have a flexible sleeve for gripping and holding a portion of the outer sheath, thereby providing a releasable attachment mechanism. In another embodiment, the inner member may include an inflatable balloon having a tapered distal region which extends from the outer sheath for providing an atraumatic tip. The inflatable balloon may also be used to expand the medical implant and to grip the outer sheath.

    Abstract: Devices and methods for reshaping a mitral valve annulus are provided. One preferred device is configured for deployment in the right atrium and is shaped to apply a force along the atrial septum. The device causes the atrial septum to deform and push the anterior leaflet of the mitral valve in a posterior direction for reducing mitral valve regurgitation. Another preferred device is deployed in the left ventricular outflow tract at a location adjacent the aortic valve. The device is expandable for urging the anterior leaflet toward the posterior leaflet. Another preferred device comprises a tether configured to be attached to opposing regions of the mitral valve annulus.

  • Publication number: 20060276890
    Abstract: Devices and methods for treating mitral regurgitation by reshaping the mitral annulus in a heart. One preferred device for reshaping the mitral annulus is provided as an elongate body having dimensions as to be insertable into a coronary sinus. The elongate body includes a proximal frame having a proximal anchor and a distal frame having a distal anchor. A ratcheting strip is attached to the distal frame and an accepting member is attached to the proximal frame, wherein the accepting member is adapted for engagement with the ratcheting strip. An actuating member is provided for pulling the ratcheting strip relative to the proximal anchor after deployment in the coronary sinus. In one preferred embodiment, the ratcheting strip is pulled through the proximal anchor for pulling the proximal and distal anchors together, thereby reshaping the mitral annulus.

  • Publication number: 20060241745
    Abstract: A blood flow controlling apparatus, which is configured to be implanted into a blood circulatory system of a patient, comprises an anchoring means, which is arranged to fix the position of the apparatus in the blood circulatory system, and a valve means being connected to the anchoring means. The valve means is configured to be arranged within the blood circulatory system and is configured to be extendable in a direction transverse to blood flow in order to make contact with native tissue when inserted in the blood circulatory system. The valve means is further configured to release said contact as a result of being exposed to blood flow in a permitted direction.

  • Publication number: 20060184230
    Abstract: A delivery system for delivering a prosthetic heart valve to a native valve site within the human vasculature. The prosthetic valve is disposed on a balloon at the end of a balloon catheter. The balloon catheter passes through a delivery sleeve assembly and handle. A pull wire travels from the handle to a distal end of the delivery sleeve assembly. Actuation of the handle pulls on the pull wire, which causes openings in a slotted tube of the delivery sleeve assembly to close, thus causing the delivery sleeve assembly to bend. A stretchable cover is placed over the slotted tube for biasing the steerable catheter toward a straight position. Once advanced to the native valve site, the prosthetic valve is deployed by inflating the balloon.
