  • Publication number: 20220079754
    Abstract: Devices, systems and methods for removal of a mitral valve clip and subsequent delivery of a mitral valve implantation in a mitral valve replacement procedure. A modular port accessory device having a distal connector configured to be compatible with corresponding connectors on an existing therapeutic device, wherein the port accessory can be selectively attached to a proximal end portion connector of a proximal end portion of a catheter assembly of an existing therapeutic device. The catheter assembly is introduced to a target site within the patient's anatomy, and remains in place throughout a multistep therapeutic procedure for use with other therapeutic devices, all while allowing hemostasis to be controlled during use ad interchange of multiple therapeutic devices.

  • Publication number: 20210346081
    Abstract: A system for cutting leaflet tissue at a cardiac valve may comprise a guide catheter having a proximal end and a distal end, wherein the distal end of the guide catheter is steerable to a position above a cardiac valve. The system may also include a handle coupled to the proximal end of the guide catheter, the handle comprising at least one control configured to steer the guide catheter to the position above the cardiac valve. Finally, the system may comprise a cutting mechanism routable through the guide catheter and able to be positioned at the distal end of the guide catheter, the cutting mechanism configured to cut a portion of leaflet tissue of the cardiac valve.

  • Publication number: 20200060687
    Abstract: Devices and methods for use in a cardiac valve repair procedure, particularly a tricuspid valve repair procedure. An interventional clip device includes a pair of distal elements rotatably joined to a coupling member, and a pair of proximal elements resiliently biased toward the distal elements to grasp tissue therebetween. The proximal elements include a plurality of adjustable tines moveable between a retracted configuration and an open configuration to avoid damage to tissue prior to engagement while allowing tines to enhance gripping to targeted tissue when open. A delivery system enables delivery of an interventional clip to a targeted cardiac valve, and includes a support structure for maintaining position relative to the cardiac valve.

  • Patent number: 10420565
    Abstract: A system for repairing a tricuspid valve in a patient's heart comprising a post having a distal end and a proximal end, a capture element attached to the distal end of the post, the capture element including: a plurality of arms each having a first end and a second end, each arm attached at the first end to the post and extending both radially outwardly from the post and proximally, each arm defining an opening at the second end; a wire passing sequentially through the opening on each arm, whereby tensioning the wire draws the second end of each arm towards the post.

  • Patent number: 9402754
    Abstract: An endoprosthesis for treating a bifurcated lumen. The distal end of the endoprosthesis can include at least two wings and at least two troughs so the endoprosthesis can adequately scaffold the ostium of a bifurcated lumen by at least partially straddling the carina of the lumen bifurcation. The distal end of the endoprosthesis can also be configured to have increased expandability to help allow conformity to the anatomy of a bifurcated lumen.

  • Publication number: 20120232528
    Abstract: The present invention is a catheter or catheter delivery system that incorporates a series of radiopaque markers at discrete, intervals corresponding to units of measurement, such as millimeters, such that structures and blockages within a body lumen can be measured in vitro using the catheter under fluoroscopy. The apparatus and method avoids estimation errors by directly measuring the designated lesion, allowing for improved selection of stents and balloons.

  • Publication number: 20110046709
    Abstract: Various methods for implanting a stent into an ostium or a proximal portion of a body vessel utilizing a guide catheter, rather than a convention balloon angioplasty balloon catheter, as the primary delivery device are disclosed. The guide catheter can be used as the primary stent delivery catheter for the ostium region of the body vessel and can be anchored to the vessel to allow secondary treatment devices to be advanced to distal locations in the body vessel.
