Publication number: 20240065729Abstract: An instrument for facilitating transseptal delivery of a cardiac therapeutic device is positionable in a left ventricle. The instrument includes an elongate shaft having a tubular lumen, the shaft having a proximal portion and a distal portion actively steerable between a generally straight position and a curved position. An external pull wire and an internal pull wire are each actuatable to move the distal portion to the curved position. The external pull wire extends internally through the proximal portion of the shaft and longitudinally along the exterior of the distal portion of the shaft, while the internal pull wire extends internally through the proximal portion of the shaft adjacent to the external pull wire, and extends internally through the distal portion of the shaft.Type: ApplicationFiled: May 17, 2022Publication date: February 29, 2024Applicant: Synecor LLCInventors: Richard S.

Patent number: 11065438Abstract: A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD.Type: GrantFiled: September 22, 2019Date of Patent: July 20, 2021Assignee: SYNECOR LLCInventors: Richard S Stack, William L Athas, Kevin Johnson, Emer M Feerick, Matthew Moran, Damian Muldoon, Liam Ruddy, William Cannon, Rory O'Brien

Publication number: 20210060297Abstract: A medical device handle for articulation of a catheter includes a housing having a cylindrical shape, a control element at least partly encompassed by the housing, the control element having a pair of cross-cut threads cross-cut in opposing directions around a longitudinal axis of the medical device handle, and a pair of pull wire mounting elements each having a mounting thread engaging with one of the cross-cut threads. The control element is mechanically coupled to each of the pull wire mounting elements via the cross-cut threads and the mounting threads without any additional gear in between. A rotation of the control element around the longitudinal axis moves the pull wire mounting elements in opposite linear directions along the longitudinal axis.Type: ApplicationFiled: September 1, 2020Publication date: March 4, 2021Applicant: Creganna Unlimited CompanyInventors: Damian Muldoon, Brian F.

Patent number: 9149608Abstract: An introducer sheath assembly comprises a tubular sheath member having a deflectable distal end portion and a sheath member lumen, a handle assembly including a steering mechanism for deflecting the distal end portion of the sheath member, and a hemostasis valve assembly. The hemostasis valve assembly includes a side port member configured to be connected to a fluid source for introducing fluid into the sheath member lumen. The side port member is axially rotatable relative to the handle assembly and the sheath member such that the side port member can remain rotationally fixed relative to the fluid source as the handle assembly and the sheath member are rotated relative to the fluid source. The side port member may also be made transparent to allow for easy visualization of air bubbles, and is also configured to allow for evacuation of any visualized air bubbles.Type: GrantFiled: December 20, 2012Date of Patent: October 6, 2015Assignee: Boston Scientific Scimed Inc.Inventors: Joseph A.
