Publication number: 20200129293Abstract: A delivery catheter for a stent. The delivery catheter may comprise a distal end and a proximal end. The distal end includes a stent attachment region adapted to receive a stent. The stent may be of the self-expanding type. The catheter further comprises a handle at its proximal end and at least one sheath which may at least partially circumferentially cover said stent such as to retain it in a collapsed configuration. The sheath is coupled at its proximal end to an actuator located on said handle portion.Type: ApplicationFiled: October 31, 2019Publication date: April 30, 2020Applicant: Symetis SAInventors: JACQUES ESSINGER, STEPHANE DELALOYE, JEAN-LUC HEFTI, LUC MANTANUS

Patent number: 10420658Abstract: Embodiments of the present disclosure are related to devices and techniques for para-valve sealing of an expandable stent-valve implanted using a catheter. In some embodiments, a stent-valve is provided which comprises a seal sleeve/cuff containing material that swells when contacted by blood. A piercing tool may be included and used to permit a user to puncture the sleeve/cuff prior to introduction into a patient's body. In some embodiments, the sleeve/cuff has an integral tubular structure configured to withstand balloon expansion of the stent-valve during or after implantation. In some embodiments, the seal is provided as a separate component from the stent-valve.Type: GrantFiled: March 13, 2014Date of Patent: September 24, 2019Assignee: SYMETIS SAInventors: Stéphane Delaloye, Jacques Essinger, Jean-Luc Hefti, Youssef Biadillah, Luc Mantanus, Fabien Lombardi, Lionel Flaction, Yutit Wanakoht
