Abstract

Features for a restraint to facilitate delivery and deployment of an implantable cardiac device are described. The restraint may include a series of circumferential engagements for securing inwardly corresponding portions of the implant. The restraint may be located inside the implant and provide a radially inward force on the implant. The restraint may include a center shaft having a series of grooves configured to cooperate with corresponding splines of the implant. Distal or proximal advance of the restraint disengages the restraint from the implant. The implant may include a tubular frame configured to contract and be secured by the restraint in a contracted configuration and to expand upon disengagement from the restraint. The restraint may provide for a smaller overall cross-sectional profile of a transcatheter delivery system, for instance by negating the need for a distal delivery sheath.

Description

[0001] Cross References to Related Applications [0002] This application is a non-provisional application of, and claims priority to, U.S. Provisional Application Serial No. 62 / 749,039, filed October 22, 2018, entitled "Delivery System with Integral Central Restraint for Implantable Cardiac Devices" rights and interests, the entire contents of which are expressly incorporated herein by reference. technical field [0003] The technology generally relates to implantable coronary medical devices. In particular, features are described for devices for constraining implants that reduce the cross-sectional profile of a delivery system enabling, inter alia, non-invasive delivery of a medical implant through its delivery system, its lumen, and the patient's anatomy . Background technique [0004] Heart valve insufficiency is a serious problem. For example, heart disease can cause the chambers of the heart to dilate and weaken. With specific reference to the mitral valve, due to...
