Publication number: 20100331972Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable coupling stent, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the coupling stent attached thereto. The coupling stent may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes a hollow two-piece handle through which a balloon catheter passes. A valve holder is stored with the heart valve and the handle easily attaches thereto to improve valve preparation steps.Type: ApplicationFiled: June 23, 2010Publication date: December 30, 2010Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Rafael Pintor, Mark Chau, Travis Oba, August Yambao, Louis A.

Publication number: 20100249894Abstract: An exemplary two-stage prosthetic heart valve system has a radially expandable base stent implanted within a native valve annulus. The two-stage heart valve system also has a valve component that is delivered to and mounted within the base stent in a separate or sequential operation after the base stent has been anchored within the annulus. The valve component in certain embodiments comprises a hybrid valve component that includes a conventional, non-expandable surgical valve that is modified to include an expandable coupling stent that can be expanded to engage the inner surface of the base stent, thereby anchoring the valve component to the base stent. In its expanded configuration, the outflow end portion base stent has tri-lobular shape that closely conforms to the shape of the aortic root and a support ring of the prosthetic valve that is mounted within the base stent.Type: ApplicationFiled: March 3, 2010Publication date: September 30, 2010Applicant: Edwards Lifesciences CorporationInventors: Travis Oba, Rafael Pintor, Louis Campbell

Publication number: 20100161036Abstract: A heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve has a base stent that is deployed at a treatment site, and a valve component configured to quickly connect to the base stent. The base stent may take the form of a self- or balloon-expandable stent that expands outward against the native valve with or without leaflet excision. The valve component has a non-expandable prosthetic valve and a self- or balloon-expandable coupling stent for attachment to the base stent, thereby fixing the position of the valve component relative to the base stent. The prosthetic valve may be a commercially available to valve with a sewing ring and the coupling stent attaches to the sewing ring. The system is particularly suited for rapid deployment of heart valves in a conventional open-heart surgical environment. A catheter-based system and method for deployment is provided.Type: ApplicationFiled: December 10, 2009Publication date: June 24, 2010Applicant: Edwards Lifesciences CorporationInventors: Rafael Pintor, Mark Chau, Travis Oba, August Yambao, Louis Campbell, Tammy Huntley, Qinggeng Zeng, Carey Cristea, Faisal Kalam

Publication number: 20100131039Abstract: A system for expanding a device in a conduit or orifice of a human body includes an expansion device that is movable from a first configuration to a second configuration. External surfaces of the expansion device can collectively have a non-cylindrical cross-section relative to a main axis of the expansion device, such that the external surfaces of the expansion device generally conform to the anatomical shape of the conduit or orifice when the expansion device is in the second configuration.Type: ApplicationFiled: November 13, 2009Publication date: May 27, 2010Applicant: EDWARDS LIFESCIENCES CORPORATIONInventors: Mark Chau, Travis Oba, Tammy Huntley, Qinggang Zeng, August Yambao, Rafael Pintor

Publication number: 20080065156Abstract: An apparatus, system, and method for repairing openings such as septal defects includes advancing a catheter to the site of the defect, grasping opposing edges of the defect, passing one or more suture lines through the opposing edges, tightening the suture lines, and deploying and expanding a fastener to secure the suture lines and close the defect. The fastener can include tissue-growth-inducing materials to encourage tissue growth onto or into the fastener and/or suture. The fastener includes a locking clip portion and a plug portion, which may be an expandable portion and/or tissue-growth-inducing portion.Type: ApplicationFiled: December 7, 2006Publication date: March 13, 2008Inventors: David L. Hauser, Richard B. Cates, Rafael Pintor, Stanton J. Rowe

Publication number: 20070073391Abstract: 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.Type: ApplicationFiled: September 28, 2005Publication date: March 29, 2007Inventors: Henry Bourang, Rafael Pintor, Jan Solem, Per Kimblad, Jan Harnek, Sepehr Fariabi

Patent number: 6030405Abstract: A dilation catheter having a balloon inflation shaft with an inflation lumen into which a stiffening wire extends and a guidewire shaft having a guide wire lumen adjacent to the balloon. The stiffening wire includes at least two stepped diameter reductions along its length to vary stiffness from a stiff proximal end providing improved pushability to a less stiff distal end providing improved trackability. A manifold at the inflation shaft proximal end includes a handle for adjusting the distance the stiffening wire extends into the inflation lumen to allow stiffness to be optimized. The handle includes a tubular flange frictionally engaging the manifold to prevent inadvertent handle movement. The balloon inflation shaft and guidewire shafts are bonded together in a manner producing an assembly having a circular cross section for improved connection to a circular balloon and improved catheter performance.Type: GrantFiled: June 25, 1998Date of Patent: February 29, 2000Assignee: Medtronic Inc.Inventors: David J.
