Patent number: 7758634Abstract: A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening.

Publication number: 20090254177Abstract: A system for delivering and deploying a self-expandable heart valve to a site of implantation such as the aortic annulus includes a deployment mechanism that engages the valve and regulates the rate of expansion of both the proximal and distal ends thereof. The heart valve may be a rolled-type valve and the deployment mechanism may include a plurality of distal fingers and a plurality of proximal fingers that engage the outer layer of the head valve. Controlled radial movement of the fingers regulates the unwinding of the rolled heart valve. The fingers may be removed prior to inflation of a balloon to fully expand the valve, or the fingers may be repositioned to the inside of the valve for this purpose. The deployment mechanism may include an umbrella structure that forces the rolled valve outward into its fully expanded configuration. Alternatively, a gear shaft that engages one or more gear tracks on the valve may be utilized to regulate expansion of the valve.Type: ApplicationFiled: June 19, 2009Publication date: October 8, 2009Applicant: Edwards Lifesciences CorporationInventors: Jibin Yang, Matthew Lane Pease, Scott Hyler Heneveld, SR., Brandon G.

Patent number: 7556646Abstract: A system for delivering and deploying a self-expandable heart valve includes a deployment mechanism that engages the valve and regulates the rate of expansion of both the proximal and distal ends thereof. The deployment mechanism may include a plurality of distal fingers and a plurality of proximal fingers that engage the end portions of the heart valve. Controlled radial movement of the fingers regulates the expansion of the heart valve such that the proximal and distal ends radially expand at the same rate. A stabilization balloon may be used to axially and radially locate the deployment mechanism relative to the site of implantation. Methods of operation of the delivery and deployment mechanism include regulating the rate of self-expansion of the valve and forcing the valve outward into its fully expanded configuration utilizing the same or different means.Type: GrantFiled: September 13, 2001Date of Patent: July 7, 2009Assignee: Edwards Lifesciences CorporationInventors: Jibin Yang, Scott Hyler Heneveld, Sr., Matthew Lane Pease, Brandon G.

Patent number: 7374571Abstract: Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery using a catheter, and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes.

Lockout tabs and making slots secure the stents in their expanded shapes. Alignment structure ensures concentric unfurling of the stent. Anchoring elements at the stent edges or in the stent body secure the valve within the annulus. A method of manufacture includes shape setting the sheet-like stent to ensure an outward bias during deployment. The stent may also include dear tracks for engagement with a gear mechanism for deployment.Type: GrantFiled: November 1, 2002Date of Patent: May 20, 2008Assignee: Edwards Lifesciences CorporationInventors: Matthew L.

Patent number: 6723122Abstract: Storage containers for expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The containers permit an expandable valve to be stored in its expanded configuration and then converted to its contracted configuration while still in the container. A mechanism incorporated into the container facilitates the conversion. For example, the container may have a base and a lid, and a crank manipulable from outside. The lid actuates a key within the container that engages the valve to perform the contraction. If the valve is a spirally wound type of expandable valve, the key may be attached to an inner side edge and rotated to wind the valve into a tight spiral. A drain in the container may facilitate removal of a preservative solution so that the valve can be seen during the contraction process, or so that the valve can be rinsed while still within the container.Type: GrantFiled: August 30, 2001Date of Patent: April 20, 2004Assignee: Edwards Lifesciences CorporationInventors: Jibin Yang, Matthew Lane Pease, Brandon G.
