20160022444 | PROSTHESIS SEALS AND METHODS FOR SEALING AN EXPANDABLE PROSTHESIS - 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. | 01-28-2016 |
20150366665 | PROSTHETIC VALVE, DELIVERY APPARATUS AND DELIVERY METHOD - A delivery catheter for a prosthetic heart valve, the valve expandable from a collapsed condition for delivery to an ex paneled condition for implantation, the delivery catheter comprising: a holder for engaging the valve in the collapsed state of the valve, the holder configured such that (i) in response to a radial compression force exerted thereon, the holder has a first shape defining an exposed engagement region for engaging at least a portion of the collapsed prosthetic heart valve for restraining axial displacement of the prosthetic valve in at least one axial direction of the catheter, and (ii) in response to removal of the radial compression force upon expansion of the valve, at least a portion of the holder transitions to a second shape. | 12-24-2015 |
