Patent number: 11944539Abstract: Systems and methods for delivering and implanting heart valves are disclosed. The delivery systems can include an integrated introducer. The integrated introducer can include a sheath having an inner diameter that is smaller than the outer diameter of a delivery capsule of the delivery system and an outer diameter that is approximately equal to the outer diameter of the delivery capsule. The integrated introducer can include a hub having a hemostatic seal. The hub can have a locking mechanism configured to fix the integrated introducer in place on the delivery system.Type: GrantFiled: January 13, 2022Date of Patent: April 2, 2024Assignee: MEDTRONIC, INC.Inventors: Susheel R. Deshmukh, Patrick Griffin, Patrick E. Macaulay, A K M. Masud, Adam J. Shipley, John P. Shanahan, Hubert K. Yeung, Stephen J. Peter, Gustaf L P Belt, Joshua J. Dwork

Patent number: 11432927Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. The implant is secured to tissue with anchors that can rotate without axial advancement to engage tissue while drawing the implant closer to the tissue. Collars are used to decrease the angle between struts of a frame to contract the implant. The implants can include a rotatable shaft, such as a threaded shaft, located internally to an axially translatable collar. Rotation of the shaft transmits force to the collar to cause the collar to translate axially, closing the angle of adjacent struts and decreasing the width of the implant and thus of the annulus. The implants can be delivered, secured and contracted via a catheter. The implants are repositionable and retrievable via catheter.Type: GrantFiled: December 18, 2019Date of Patent: September 6, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Michael J. Lee, Patrick E. Macaulay, Kenny D. Bruner, Padraig J. Savage, Nathan D. Brown

Patent number: 8540694Abstract: Systems and methods for delivering drugs or other substances to target locations outside of blood vessel lumens or other body lumens. In some embodiments, a catheter having a penetrator is advanced into the body lumen and the penetrator is then advanced from the catheter toward a target location outside of that body lumen. The substance is then delivered through a the penetrator itself or through a delivery catheter that has been advanced through the penetrator to the target location. In other embodiments, the blood vessel or other body lumen is blocked at spaced-apart first and second locations and a quantity of the substance is introduced into the closed-off body lumen between the blocked first and second locations. The substance then diffuses into or through the wall of the vessel or body conduit to reach the target location.Type: GrantFiled: December 27, 2011Date of Patent: September 24, 2013Assignee: Medtronic Vascular, Inc.Inventors: J.

Patent number: 8414645Abstract: Delivery devices and methods for percutaneously delivering a prosthetic valve to the heart of a patient. These prosthetic valves may be configured to provide complimentary features that promote optimal placement of the prosthetic valve in a native heart valve, such as the aortic valve, mitral valve, pulmonic valve, and/or tricuspid valve. The delivery device includes a release sheath assembly housed within an outer delivery sheath. A release sheath component of the assembly captures a portion of the prosthetic valve to the delivery device, and effectuates complete release of the prosthetic valve with retraction of the outer sheath.Type: GrantFiled: August 27, 2010Date of Patent: April 9, 2013Assignee: Medtronic, Inc.Inventors: Joshua Dwork, Patrick E. Macaulay, Gianfranco M. Pellegrini, Finn O. Rinne, Richard Spork, Don Huy Tran, Nathan B. Wiemeyer
