An edge of a flexible leaflet is disposed between the first and second leaflet receiving surfaces to attach the leaflet to the upper and lower frame sections. | 2020-08-20 |
20200261226 | HYDRAULIC DELIVERY SYSTEMS WITH FLOW DIVERSION DEVICES AND ASSOCIATED METHODS - A flow diversion device configured in accordance with embodiments of the present technology may include, for example, a housing including openings to channels that intersect at a junction. The flow diversion device may also include, for example, a flow control component disposed at the junction and movable to selectively form pathways for fluid communication based on a position of the flow control component. For example, when the flow control component is in a first position, a first pathway may allow fluid flow causing deployment of the prosthetic heart valve device and, when the flow control component is in a second position, a second pathway may allow fluid flow causing recapture of the prosthetic heart valve device. The flow diversion device may include a handle movable to position the flow control component in the first or second positions thereby selectively controlling fluid flow of the delivery system. | 2020-08-20 |
20200261227 | EXPANDABLE SHEATH AND METHODS OF USING THE SAME - Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for an implant, then return to a non-expanded state after the passage of the device. The sheath includes a foldable inner member having a detached flap structure at its distal tip that facilitates expansion of the sheath lumen to increased diameters, and an elastomeric distal end that reduces push and retrieval forces therethrough. The sheath can include a hemostasis seal on its proximal end to prevent the leakage of blood out of the sheath and prevent ballooning of outer layer of the sheath. | 2020-08-20 |
20200261228 | Post-Implantation Tensioning in Cardiac Implants - A method of treating a heart of a patient is provided. The method includes implanting a first tissue anchor in cardiac tissue of the patient and a second tissue anchor in the patient, such that the first and the second tissue anchors are coupled together by one or more tethers. Thereafter, after allowing at least 24 hours for tissue growth on the first tissue anchor to strengthen anchoring of the first tissue anchor in the cardiac tissue, tension is applied between the first and the second tissue anchors using at least a longitudinal portion of the one or more tethers. Other embodiments are also described. | 2020-08-20 |
20200261229 | A SURGICAL PROCEDURE FOR CANCEROUS MANDIBULAR RECONSTRUCTION AND A TEMPORARY MANDIBULAR SPACER THEREFOR - There is provided herein a surgical procedure for cancerous mandibular reconstruction and a temporary mandibular spacer therefor. The spacer is a structural load-bearing and rigid/stiff interim space maintenance device that can be used by surgeons to temporarily bridge the gap across a resected part of the mandible. The device may be made of a rigid and biocompatible polymer material which is anatomically shaped like a natural mandible. During surgery, the mandibular spacer may be quickly cut with a surgical saw into the desired lengths by the surgeon which may more precisely match the resected segment of native mandible. The length and the shapes of the terminal ends of the spacer may be configured to more precisely maintain the position of the remaining mandibular segments in their original locations and thus preserve the occlusion and surrounding soft tissues in their correct anatomical positions, reducing or eliminating scarring and/or malocclusion. | 2020-08-20 |
