  • Patent number: 9615775
    Abstract: Devices and methods for accurately determining the size of an ostium of a patient and in particular sinus ostium. Methods for measuring a target ostium comprise inserting the distal end portion of an ostium measuring device into a patient, locating the target ostium with the measuring device, positioning the distal end portion of the measuring device appropriately adjacent to or into the target ostium and determining the diameter(s) of the target ostium by comparing the length, diameter and/or the circumference of the portion of the distal end portion of the measuring device adjacent to or within the target ostium.

  • Patent number: 9603506
    Abstract: Devices and methods for visually confirming the positioning of a distal end portion of an illuminating device placed within a patient include inserting a distal end portion of an illuminating device internally into a patient, emitting light from the distal end portion of the illuminating device, observing transillumination resulting from the light emitted from the distal end portion of the illuminating device that occurs on an external surface of the patient, and correlating the location of the observed transillumination on the external surface of the patient with an internal location of the patient that underlies the location of observed transillumination, to confirm positioning of the distal end portion of the illuminating device.

  • Publication number: 20160324640
    Abstract: Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

  • Publication number: 20160213758
    Abstract: A system for delivering a therapeutic agent to a nasopharyngeal mucosa target comprises a foam generating mechanism, a gas, a therapeutic agent in liquid form that inhibits mucus production, and a delivery device. Actuation of the foam generating mechanism entraps gaseous bubbles from the gas in the liquid thereby forming a foam. The therapeutic agent is dispersed in the foam which has an expanded configuration adapted to fill a nasopharyngeal space and deliver the therapeutic agent to the mucosa targets. The delivery device is for delivering the foam to the nasopharyngeal space. The foam may also have a collapsed configuration for removal from the nasopharyngeal space or for concentration of the therapeutic agent onto the mucosa.

  • Patent number: 9295552
    Abstract: Devices and methods for implantation at a native mitral valve having a non-circular annulus and leaflets. One embodiment of the device includes a valve support having a first region configured to be attached to a prosthetic valve with a plurality of prosthetic leaflets and a second region. The device can further include an anchoring member having a longitudinal dimension and including a first portion configured to contact tissue at the non-circular annulus, a second portion configured to be attached to the valve support, and a lateral portion between the first portion and the second portion. The second portion of the anchoring member is attached to the second region of the valve support while in a low-profile configuration in which the anchoring member and the valve support are configured to pass through vasculature of a human. The lateral portion is transverse to the longitudinal dimension.

  • Publication number: 20160038280
    Abstract: Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an anchoring member having an upstream portion configured to engage with tissue on or near the annulus of the native heart valve and to deform in a non-circular shape to conform to the tissue. The device can also include a mechanically isolated valve support coupled to the anchoring member and configured to support a prosthetic valve. The device can further include an atrial extension member extending radially outward from the upstream portion of the anchoring member and which is deformable without substantially deforming the anchoring member. In some embodiments, the upstream portion of the anchoring member and the extension member may be deformed while the valve support remains sufficiently stable.

  • Publication number: 20150351903
    Abstract: A prosthetic heart valve device (100) for percutaneous replacement of a native heart valve includes an expandable retainer (110) at least partially surrounding and coupled to an inner valve support (120). The device can further include a prosthetic valve (130) coupled to the valve support. The retainer forms a donut-shaped flange (190) having an arcuate outer surface (142) for engaging tissue and an inner lumen defining a passage for blood to flow through the valve support. The retainer can include a plurality of circumferentially positioned, resiliency deformable and flexible ribs (114) which are coupled at their downstream ends 116 to the valve support 120. The flexible ribs, in one embodiment, can have a general C-shape configuration with the tips (117) of the flexible ribs and an opening (119) of the C-shape configuration oriented toward a longitudinal axis (101) of the device.
