Summary
The USPTO has granted a new patent (US12582539B2) to Medtronic for a clamshell iris-style crimper designed for medical devices. The patent details an innovative mechanism for compressing expandable medical devices, featuring a handle-operated clamshell design that reduces chamber volume to achieve compression.
What changed
The United States Patent and Trademark Office (USPTO) has issued patent US12582539B2 to Medtronic, Inc. for a novel clamshell iris-style crimper. This patent covers a device designed to compress expandable medical devices, featuring a rotatable top iris shell and a base iris shell that together form a crimper chamber. The mechanism is operated by a handle, which decreases the chamber volume to transition the medical device from an uncompressed to a compressed state.
This patent grant signifies an addition to Medtronic's intellectual property portfolio in the medical device sector. While this is a patent grant and not a regulatory rule imposing new compliance obligations, it highlights innovation in the field of medical device manufacturing and deployment. Companies involved in similar device compression technologies may wish to review the patent details to understand the scope of Medtronic's claims and to ensure their own products do not infringe upon this granted patent.

Clamshell iris-style crimper for medical devices

Abstract
A crimper includes a top iris shell defining a top iris channel. The crimper also includes a base iris shell coupled to the top iris shell at a pivot connection, the base iris shell defining a base iris channel. The top iris shell is configured to rotate about the pivot connection relative to the base shell from an open state to a closed state. When in the open state, the base iris channel is exposed for loading the expandable medical device. When in the closed state, the top iris channel and the base iris channel define a crimper chamber. The crimper also includes a handle configured to operate the clamshell crimper. The actuation of the handle decreases a volume of the crimper chamber to transition the expandable medical device from the uncompressed state to the compressed state.
