Publication number: 20220409885Abstract: A biostimulator delivery system having a tether cable, is described. A connector can be mounted on the tether cable to connect to a biostimulator. The connector can be a protuberance that lodges within the biostimulator, or a threaded connector that screws into the biostimulator. The tether cable has a stranded cable configuration, including several strands extending about a core strand in a helical direction. The stranded cable structure resists breaking under bending stresses typically seen during a tether mode used during delivery of the biostimulator. The tether cable reliably secures the biostimulator to the delivery system in the tether mode. Other embodiments are also described and claimed.Type: ApplicationFiled: June 23, 2021Publication date: December 29, 2022Inventors: Bernhard Arnar, Keith Victorine, Shawn X. Chen, Mike Sacha, Mark Krans, Andy Servi, Jeremiah Blue, Adam Weber

Patent number: 9486348Abstract: A delivery device and method for deploying a stent-graft within a body lumen of a patient are provided. According to one embodiment, the delivery device includes a tubular member lock that couples an outer tubular member of the device with an inner tubular member, such that as the outer tubular member is retracted to deploy the stent-graft, the distal-most end of the delivery device is also retracted. In one embodiment, the delivery device also includes a stent lock disposed on an intermediate tubular member that is configured to releasably couple the stent-graft and the intermediate tubular member. The inner tubular member and the outer tubular member are configured to be coupled to one another such that movement of the outer tubular member results in movement of the inner tubular member with respect to the intermediate tubular member so as to deploy the stent-graft.Type: GrantFiled: February 1, 2011Date of Patent: November 8, 2016Assignee: S.

Patent number: 9039752Abstract: A device and method for delivering a vascular device to a target site is provided that maintains a proximal portion of the vascular device within a tubular sleeve by positioning a stop of an inner member at a distal opening of the tubular sleeve to block the opening. Once the stop has been moved distally via movement of the inner member to clear the opening, a band of increased thickness on the inner member can urge the proximal portion of the vascular device out of the tubular sleeve to deploy the vascular device. The vascular device may be recaptured within a delivery sheath prior to the full deployment of the proximal portion of the vascular device from the tubular sleeve by re-positioning the stop at the distal opening to hold the vascular device within the tubular sleeve as the delivery device is retracted with respect to the delivery sheath.Type: GrantFiled: September 20, 2011Date of Patent: May 26, 2015Assignee: AGA Medical CorporationInventors: Patrick Russo, Mark Krans, Matthew C.

Publication number: 20140371844Abstract: A prosthetic heart valve includes a collapsible and expandable stent, a collapsible and expandable valve assembly disposed within the stent, and one or more features coupled to the stent for at least partially anchoring the prosthetic heart valve within a native valve annulus of a patient. The anchoring features may include a body transitionable from an unfurled condition to a furled condition, the furled condition forming a flange for at least partially anchoring the heart valve, and/or a plurality of hooks transitionable from a deformed condition to a relaxed condition for at least partially anchoring the heart valve. A delivery device for the prosthetic heart valve may include a handle and a catheter member extending from the handle and having a first portion, a second portion, and a compartment for receiving the valve. The delivery device may provide for staged deployment of the valve.Type: ApplicationFiled: June 17, 2014Publication date: December 18, 2014Inventors: Theodore Paul Dale, Mathias C.
