US 2018/0369004 A1 · GUIDE CAP AND LOADING SYSTEM FOR LOADING IMPLANT INTO DELIVERY SYSTEM

Abstract

A guide cap and a loading system for loading an implant into a delivery system are disclosed which are capable of simplifying operations required in interventional surgery using the implant. The guide cap has a lumen passing therethrough and includes: a conical section; a straight or conical tube in communication with a small open end of the conical section; and a flange, wherein a large open end of the conical section flares outward and thereby forms the flange. The loading system includes a guider and the guide cap. During the process of loading the implant into the delivery system, the guide cap enables the valve prosthesis to be coupled to the connector of the delivery system and allows the valve prosthesis to be compressed so as to be entirely capsuled in the delivery system with relatively easy and quick operations, thereby reducing surgery time during its clinical use.

A loading system for loading an implant into a delivery system, comprising a guider and a guide cap, wherein the guide cap having a lumen passing therethrough and comprising:

a conical section;
a straight or conical tube in communication with a small open end of the conical section;
and
a flange, wherein a large open end of the conical section flares outward and thereby forms the flange,
wherein the guider has a circumferential surface tapered along an axis of the guider and thus forms a large open end at a first edge and a small open end at a second edge of the circumferential surface, the small open end of the guider having a diameter greater than a diameter of the small open end of the conical section of the guide cap;
and
wherein the guide cap and the guider are so sized that the flange is able to cover the large open end of the guider, with an end portion of the straight or conical tube protruding from the small open end of the guider.
