Abstract

Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the riskof injury to the patient.

Description

[0001] Cross References to Related Applications [0002] This application is and claims the benefit of priority from U.S. Provisional Application Serial No. 62 / 699,887, filed July 18, 2018, and entitled "Deployment Restraint and Delivery System for Implantable Cardiac Devices" , the entire content of which application is expressly incorporated herein by reference. technical field [0003] The present technology generally relates to implantable arterial medical devices. In particular, features are described for a device for constraining implants that reduces the cross-sectional profile of a delivery system to enable, among other things, medical treatment through its delivery system, its passageway, and the patient's anatomy Non-invasive delivery of implants. 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, dilation...
