Patent number: 10702275Abstract: One exemplary device includes a tubular structure having proximal and distal ends and at least one layer of braided material configured to facilitate thrombosis. The tubular structure includes an end section at the proximal or distal end having a cross-sectional dimension that is larger than that of an opening of the target site. The device also includes a stiffener wire coupled to the tubular structure, and the wire is configured to extend at least partially through the opening and facilitate securing the end section over the opening. The tubular structure and stiffener wire include respective preset, expanded configurations and are configured to be constrained to respective reduced configurations for delivery to the target site and to at least partially return to their respective preset, expanded configurations at the target site when unconstrained.Type: GrantFiled: February 18, 2009Date of Patent: July 7, 2020Assignee: St. Jude Medical Cardiology Division, Inc.Inventors: Daniel O.

Patent number: 10315018Abstract: Disclosed is a balloon catheter that can comprise an elongate support member, an inflation tube, a guidewire tube and a balloon. The guidewire tube can define a guidewire port at its proximal end, and can extend from the port through an opening in a wall of the elongate support member and distally through a first lumen of the elongate support member, in some cases to the distal end of the catheter. The inflation tube can be disposed over a distal portion of the elongate support member, a portion of the guidewire tube, a portion of the inner assembly, or any combination thereof, forming a second lumen. The distal end of the balloon can be attached to the guidewire tube and the proximal end of the balloon can be attached to the inflation tube. The inside of the balloon can be in fluid communication with the first lumen and with the second lumen, allowing the balloon to be inflated and/or deflated. The elongate support member can also have cuts in it.Type: GrantFiled: May 16, 2016Date of Patent: June 11, 2019Assignee: BOSTON SCIENTIFIC SCIMED INC.Inventors: Tracee E. J. Eidenschink, Matthew C.

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: 9427304Abstract: A medical device includes a multi-layered structure comprising an inner layer disposed within an outer layer, wherein each of the inner and outer layers has respective inner and outer surfaces. The multi-layered structure further comprises at least offset located between the inner and outer layers or formed in the inner and/or outer layers to define at least one gap therebetween such that a majority of the outer surface of the inner layer is spaced apart from the inner surface of the outer layer. The multi-layered structure is configured to be deployed within a lumen such that at least a portion of the outer layer is configured to engage the lumen and the at least one gap is configured to promote thrombosis between the inner and outer layers.Type: GrantFiled: October 27, 2008Date of Patent: August 30, 2016Assignee: ST.

Patent number: 9402634Abstract: A vascular device is provided that includes a tubular structure and an occluding structure. The tubular structure has inner and outer layers, with the occluding structure located between the inner and outer layers. Each of the inner and outer layers may define a different pick count, and the tubular structure may include a leading edge at a transition between the pick counts. The leading edge may be disposed at the distal end of the vascular device when the device is deployed from a delivery device. Furthermore, the occluding structure may have first and second layers formed by the inversion or eversion of the occluding structure and the subsequent coupling of its free ends to form a continuous structure. Thus, any loose ends may be sealed to minimize unraveling and/or shifting of the occluding structure within the tubular structure. A method of making the vascular device is also provided.Type: GrantFiled: November 26, 2013Date of Patent: August 2, 2016Assignee: ST. JUDE MEDICAL, CARDIOLOGY DIVISION, INC.Inventors: Patrick Russo, John Oslund, Matthew C. Heidner, Jessica Akers

Patent number: 9232992Abstract: Embodiments of the present invention provide medical devices and methods for treating a target site within the body, such as for treating vascular abnormalities. For example, one embodiment provides a stent graft including an occlusive material having a preset, overlapping configuration comprising at least three inverted overlapping layers that are folded over one another. The at least three inverted overlapping layers are configured to be separated and disposed within a catheter in a non-overlapping configuration and return to the preset, overlapping configuration when deployed from the catheter.Type: GrantFiled: July 24, 2008Date of Patent: January 12, 2016Assignee: AGA MEDICAL CORPORATIONInventors: Matthew C.

Patent number: 9113890Abstract: Medical devices are provided that include at least one layer that defines a proximal end, a distal end, and an expanded volume portion between the proximal and distal ends. The expanded volume portion defines a longitudinal axis extending between the proximal and distal ends. A first end feature including a reversible connection for attachment to a pusher member may be attached to the proximal end. The first end feature may define a first axis between its opposing ends. Similarly, a second end feature defining a second axis between its opposing ends may be located at the distal end. In the contracted state (e.g., when constrained within a delivery catheter), the first axis and the second axis may be aligned with the longitudinal axis, and in the expanded state (e.g., when deployed), the first axis and/or the second axis may be angled with respect to the longitudinal axis.Type: GrantFiled: February 6, 2012Date of Patent: August 25, 2015Assignee: AGA MEDICAL CORPORATIONInventors: Anup Dasnurkar, Jana Santer, Matthew C.

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.
