Publication number: 20240261097Abstract: Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a covering feature associated with the spindle for selectively covering at least a portion of a stented prosthetic heart valve tethered to the spindle in a delivery state. In some embodiments, the covering feature includes a tip mounted to the spindle. The tip can include an overhang region for selectively covering a portion of the stented prosthetic heart valve. In other embodiments, the tip can include a tip body and a compressible foam bumper. In yet other embodiments, the covering feature includes an outer sheath arranged to selectively cover the stented prosthetic heart valve. The outer sheath can be elastic and stretchable for recapturing a partially expanded prosthesis, for example by including one or more windows covered by a stretchable covering layer.Type: ApplicationFiled: March 19, 2024Publication date: August 8, 2024Inventors: Brendan Vaughan, Maeve Britton, Martha Barajas-Torres, Susheel Deshmukh, Leonel Mendoza, Siyan Som, Michele Silver, Don Tran, Nathan Brown, Jill Mendelson

Patent number: 11974919Abstract: Delivery devices for delivery of a stented prosthetic heart valve. Various delivery devices include an outer sheath assembly including an outer sheath connected to a capsule that is advanced proximally to retain the prosthetic valve, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper to provide a smooth transition of the capsule over the prosthetic valve during loading and recapture procedures. The bumper is expandable from a first position to a second position in which a distal end of the bumper is expanded to increase its diameter. The bumper can be biased in the second, expanded position so that the bumper automatically transitions to the expanded position upon retraction of the outer sheath.Type: GrantFiled: July 22, 2022Date of Patent: May 7, 2024Assignee: MEDTRONIC VASCULAR, INC.Inventors: Don Tran, Martha Barajas-Torres, James Mitchell, Leonel Mendoza, Siyan Som, Jill Mendelson, David Grossman

Publication number: 20240138981Abstract: Delivery devices for delivering a self-expanding prosthetic heart valve are disclosed. The delivery device includes at least one cord is configured to selectively cinch the self-expanding prosthetic heart valve. The delivery device further includes at least one self-expanding release pin comprising a proximal segment, a distal segment, and an intermediate segment positioned between the proximal segment and the distal segment. The at least one self-expanding release pin includes a normal, expanded condition wherein the intermediate segment extends radially outward relative to a central axis of the spindle from the proximal segment to the distal segment. The delivery device further includes a capsule configured to be distally extended relative to the spindle to collapse the at least one self-expanding release pin from the normal, expanded condition of the at least one self-expanding release pin to a collapsed condition of the at least one self-expanding release pin.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Jill Mendelson, Michele Silver, Michael Gloss, Timothy Groen, Paul Rothstein, Jeffrey Sandstrom, Phil Haarstad, Joel Racchini, David Blaeser

Patent number: 11903828Abstract: Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connected to the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.Type: GrantFiled: July 21, 2020Date of Patent: February 20, 2024Assignee: MEDTRONIC VASCULAR, INC.Inventors: Jill Mendelson, Michele Silver, Michael Gloss, Timothy Groen, Paul Rothstein, Jeffrey Sandstrom, Phil Haarstad, Joel Racchini, David Blaeser

Publication number: 20240016605Abstract: Numerous delivery devices for delivery of a stented prosthesis, such as a stented prosthetic heart valve. Various delivery devices include a capsule that is advanced proximally to retain the stented prosthesis, which is secured over an inner shaft assembly of the delivery device. The delivery device further includes a bumper or bumper assembly to provide a smooth transition of the capsule over the stented prosthesis. In some alternate disclosed embodiments, the bumper further serves to connect various elements of the inner shaft assembly. Additional embodiments include a bumper assembly arranged and configured to longitudinally expand and contract to substantially fill any open space as the capsule is retracted from the stented prosthesis, which prevents kinking in the capsule. Additional embodiments include proximal and/or distal bumpers for temporarily covering and smoothing the ends of the stented prosthesis as part of a delivery device that does not include a capsule.Type: ApplicationFiled: September 29, 2023Publication date: January 18, 2024Inventors: Don Tran, Martha Barajas-Torres, Marian Lally, Michael Gloss, Timothy Groen, Leonel Mendoza, Siyan Som, Michele Silver, Nathan Brown, Jill Mendelson

Publication number: 20230001057Abstract: Biodegradable magnesium alloy implantable medical devices are protected to delay onset of corrosion, and thus biodegradability, or to corrode more uniformly. The protection allows for extended effective use of the devices while maintaining biodegradability. Examples of protective coatings include conversion coatings that at least partially remove exposed second phases from a surface of the magnesium alloy and coatings that provide a barrier between water and the surface of the magnesium alloy.Type: ApplicationFiled: September 9, 2022Publication date: January 5, 2023Inventors: Syamala Rani Pulugurtha, Jeffrey Allen, James Mitchell, Christopher Storment, Jill Mendelson
