AI Technical Summary

Technical Problem

In the prior art, during the loading process, the flange and awl of the heart valve prosthesis with dual anchors are prone to twisting, and the main support collapses radially, resulting in poor loading quality, which may cause abnormal conditions of the heart valve prosthesis and increase surgical risks.

Method used

The loading system, consisting of a main body, a gathering plate, and a gathering tube, uses a gripping channel, a limiting groove, and gathering wires to achieve uniform gripping and positioning of the flange and the gripper, preventing twisting and collapse and improving loading quality.

Benefits of technology

This effectively avoids twisting of the flange and the lug, reduces the collapse of the main support, ensures the stability of the heart valve prosthesis in the delivery device, and reduces surgical risks.

Abstract

This invention provides a loading system and loading method. The loading system includes a main body, a receiving plate, and a receiving tube. The main body has a gripping channel extending through it axially. The receiving plate has a first central through hole extending through it axially. A plurality of first limiting grooves are circumferentially spaced along the first central through hole on one end face of the receiving plate. The first limiting grooves extend radially along the first central through hole. A plurality of second limiting grooves are circumferentially spaced on the inner wall of the receiving tube. The second limiting grooves extend through it axially. One end of the receiving plate with the first limiting grooves can be connected to the main body, and the receiving tube can be connected to the end of the receiving plate away from the main body, so that the lumen of the receiving tube, the first central through hole, and the gripping channel are coaxially connected, and the plurality of second limiting grooves are arranged in a one-to-one correspondence with the plurality of first limiting grooves. By using the loading system to grip a heart valve prosthesis with a flange and a gripper, and loading the gripped heart valve prosthesis into the delivery device, the loading quality can be effectively improved.
