Publication number: 20220079754Abstract: 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.Type: ApplicationFiled: September 15, 2021Publication date: March 17, 2022Inventors: Shengmin Mei, Preston Huddleston, Laura M.

Publication number: 20200060687Abstract: 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.Type: ApplicationFiled: November 4, 2019Publication date: February 27, 2020Applicant: Evalve, Inc.Inventors: Carlos G.

Patent number: 9402754Abstract: 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.Type: GrantFiled: May 18, 2010Date of Patent: August 2, 2016Assignee: ABBOTT CARDIOVASCULAR SYSTEMS, INC.Inventors: Gregory W.

Publication number: 20120232528Abstract: 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.Type: ApplicationFiled: March 7, 2011Publication date: September 13, 2012Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Erik D.

Publication number: 20110046709Abstract: 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.Type: ApplicationFiled: August 18, 2009Publication date: February 24, 2011Applicant: ABBOTT CARDIOVASCULAR SYSTEMS, INC.Inventors: Lorcan J.
