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.

Guide cap and loading system for loading implant into delivery system

A drive handle and system for delivering an implant are disclosed. The drive handle includes a manual control unit, an electrical control unit and a transmission mechanism. The manual control unit is connected to the transmission mechanism to actuate the transmission mechanism to drive a delivery catheter for delivering the implant. The electrical control unit is connected to the transmission mechanism to actuate the transmission mechanism to drive the delivery catheter. The drive handle is switchable between a manual drive/control mode and an electrical drive/control mode to drive the delivery catheter to deliver the implant. The operation is simple, and the operating physician can take full advantage of the two modes to perform the surgical procedure based on his/her own operational preferences. This can result in higher surgical accuracy. Further, by providing these two modes, the apparatus has an increased the security and a reduced surgical risk.

Driving handle for delivering implant, and delivery system

An implant capsule () and an implant delivery system are disclosed. The implant capsule () includes, sequentially from a proximal end to a distal end, a flexural section (-), a reinforcement section (-) and a radiopaque reinforcement ring (-). The reinforcement section (-) has higher strength than the flexural section (-). The implant delivery system includes the implant capsule (). The implant capsule () can ensure the implant to be deployed in a coaxial condition and prevent over-expansion due to large expansion forces exerted by a stent of the implant.

A device and method for loading an implant into a delivery system are disclose which are capable of simplifying operations required in interventional surgery using the implant. The device includes a guide cap (), a guider () and a guiding tube (). The guide cap () has a conical section () and a straight or conical tube () in communication with a small open end () of the conical section, and the conical section has a large open end () that flares outward, thereby forming a flange () facing the tube (). The guider () has tapered sections () that are tapered along an axis of the guider and thus form large and small open ends (). The small open end () has a diameter greater than a diameter of the small open end () of the conical section of the guide cap (). The guide cap () and the guider () are so sized that the flange () can cover and be locked to the guider (), with an end portion of the straight or conical tube () protruding from the small open end () of the guider (). The guiding tube () is a round tube with two open ends, in which the first open end has a diameter greater than the diameter of the small open end () of the conical section of the guide cap and smaller than the diameter of the small open end () of the guider.

Device and method for loading implant into delivery system

An electric handle for delivering an implant is disclosed. The electric handle () includes an electric control unit (), a power-driven transmission mechanism (), a handle housing (), an outer tube anchor () and an inner tube anchor (), wherein: the electric control unit () is operatively coupled to the power-driven transmission mechanism () to actuate the power-driven transmission mechanism (); the power-driven transmission mechanism () is supported within the handle housing () and moveable together with the outer tube anchor (); the inner tube anchor () is disposed within the handle housing () and is configured to hold an inner tube () of a delivery system; and the outer tube anchor () is configured to hold an outer tube () of the delivery system and is fixed to an end of the outer tube (). A delivery system used especially for delivery of prosthetic valves is also disclosed, including an outer tube (), an inner tube (), an expandable implant () and the electric handle ().

Electric handle for implant delivery and delivery system

An implant delivery system is disclosed which includes an inner tube assembly, an outer tube assembly and a functional handle. The functional handle includes a threaded rod, a push-pull control member, a casing tube, a displacement tube, an inner tube fixing member, an outer tube fixing member and a stability tube fixing member. The threaded rod extends through a bore of the displacement tube. A fastener of the push-pull control member is able to engage a thread provided on a leading portion of the threaded rod. A trailing portion of the threaded rod is provided with a knob. The push-pull control member includes a fastener, springs and a button. The fastener is able to extend through a slot to engage a thread of the threaded rod in the displacement tube. The springs are configured to cause an automatic locking of the fastener and the threaded rod. The button is provided on the fastener. A cylindrical shell drives the displacement tube to move forward or backward along its longitudinal axis to cause the outer tube assembly to accordingly advance or retract. The delivery system can quickly, stably and accurately insert an implant into a target location.
