Delivery device and medical implant maintaining gaps upon crimping

摘要

The present invention relates to an implant (1), intended to be detachably fixed or crimped on a portion or an outer surface (23) of a catheter (5) for being delivered to an implantation site, the implant (1) having a longitudinal axis (19), or an inner space or inner volume longitudinally extending within the implant (1), and having a radial direction perpendicular to the longitudinal axis (19), space or volume. The implant (1) comprises a first structural element having a first portion (31) and a second structural element having a second portion (33) and one or more interconnecting elements arranged between the first and the second structural elements. In the implant (1), the first and/or the second portions (31, 33) are located less radially as regards the longitudinal axis (19), the inner space or volume than a third portion (24) of the one or more interconnecting elements. The invention further relates to a method and a delivery device.
