Publication number: 20240164896Abstract: A tunable fixation device for fixation of heart valve leaflets includes a central assembly, an arm moveably coupled to the central assembly, and a gripping element moveable relative to the arm to capture a native leaflet therebetween. The arm has a body portion and a wire frame coupled to the body portion. The wire frame has a first and second wire segment, and an interconnection portion interconnecting the first and second wire segments. The interconnection portion is slidingly engaged with the body portion. The first wire segment is configured to deform upon force applied to the second wire segment by sliding movement of the interconnection portion relative to the body portion, and the second wire segment is configured to deform upon force applied to the first wire segment by sliding movement of the interconnection portion relative to the body portion.Type: ApplicationFiled: November 17, 2023Publication date: May 23, 2024Applicant: Evalve, Inc.Inventors: Chad J. Abunassar, Grant Glaze, Cindy Chaoyun Yang, Jill McCoy, Jessie A. Garcia, Jonathan Cox, Samir Jain, Scott Mosher, Roisin Verbael

Publication number: 20230038339Abstract: A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.Type: ApplicationFiled: September 27, 2022Publication date: February 9, 2023Inventors: Rommel LUMAUIG, Joel HARRINGTON, Chad ABUNASSAR, David D. HART, Cornel I. CIUREA, Mark A. RITCHIE, Jay A. KING, Jill McCoy

Patent number: 10660773Abstract: A medical device includes a balloon expanded scaffold crimped to a catheter having a balloon. The scaffold has a network of rings formed by struts connected at crowns and links connecting adjacent rings. The scaffold is crimped to the balloon by a process that includes using protective polymer sheaths or sheets during crimping, and adjusting the sheaths or sheets during the crimping to avoid or minimize interference between the polymer material and scaffold struts as the scaffold is reduced in size.Type: GrantFiled: February 14, 2017Date of Patent: May 26, 2020Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Karen J. Wang, Edward P. Garcia, Boyd V. Knott, Jill A. McCoy, Ashleigh Z. Sheehy

Patent number: 10449074Abstract: A sheath used to protect a medical device has one or more strips formed over a portion thereof. The medical device is a scaffold crimped to a balloon and mounted to a catheter. The sheath is two-piece, including a protecting and constraining sheath part. The strips facilitate removal of the constraining sheath from the scaffold in manner that reduces instances of damage caused by improper removal of the sheath from the medical device.Type: GrantFiled: May 5, 2016Date of Patent: October 22, 2019Assignee: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Khanh Duong, Jill A.
