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.

The devices and methods described herein relate to improved structures for removing obstructions from body lumens. Such devices have applicability in through-out the body, including clearing of blockages within the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

A device for loading a prosthesis onto a delivery system includes a first housing having a central bore. One or more actuators on the first housing may be actuated radially inward to selectively compress a discrete portion of the prosthesis disposed in the central bore.

A radio frequency ablation medical device includes a guide wire; a catheter configured to be movable to a lesion site of a tissue along the guide wire and having at least one electrode configured to generate heat according to an application of power; and a stent configured to be unfolded when protruding out of the catheter through an end portion of the catheter or recaptured in the end portion of the catheter when entering an inside of the catheter. The stent serves to transfer heat generated by the electrode to the lesion site in an unfolded state when getting out of the catheter.

The present embodiments provide systems and methods for treating a medical condition. In one embodiment, the system comprises a stent having proximal and distal regions, and further having a delivery state and an expanded state. A therapeutic agent is disposed on a segment of the stent. The stent is disposed around an exterior surface of a core assembly in the delivery state. A coupling assembly releasably secures the proximal region of the stent to the exterior surface of the core assembly. The coupling assembly secures the stent to the core assembly for a predetermined period while the stent is in the expanded state and during release of the therapeutic agent at a target site. The coupling assembly further enables the stent to be disengaged from the core assembly and deployed in a bodily passageway.

Described herein are systems and methods for the treatment of branching blood vessels. The system can be introduced percutaneously or by surgical cutdown into a patient's arterial system. The bifurcation from the aorta to the iliac arteries (aortic bifurcation) is used as an example of a branching blood vessel which can be treated with the systems described herein. Also, described herein are methods for assembling the medical devices.
