The proposal is for a holding element (100) which can be screwed into the internally threaded bore (14) of the implant (1) even during production of the latter and can thus be used to grip or hold the implant for the following production phases. Furthermore, the holding element (100) serves to fix an implant (1), which is screwed thereto, inside an ampoule (200) and for the application of a screwing-in tool for implantation. The particular feature of the ampoule (200) lies in the fact that it has a large-area, lateral cutout (231) in the casing and also a fixing part (210) for accommodating the holding element (100) in a clamped manner. The implant (1) can thus be pulled laterally out of the ampoule (200). The devices facilitate handling of the implant (1) during production and insertion into the bone.

A minimally invasive approach for surgery on portions of the heart and great vessels. A parasternal incision is made extending across a predetermined number of costal cartilages, e.g., a right parasternal incision extending from the lower edge of the second costal cartilage to the superior edge of the fifth costal cartilage. One or more costal cartilages, e.g., the third and fourth, are then excised to provide access to the portion of the heart or great vessels of interest, for example between a point approximately three centimeters above supra annular ridge and the mid ventricular cavity, and a desired procedure completed. A minimally invasive procedure for repair or replacement of the aortic valve is disclosed that includes making a transverse incision of about 10 cm in length over the second or third intercostal space in the thorax of the patient, dividing the sternum transversely following the incision, retracting the transversely divided sternum, exposing the ascending aorta, and incising the ascending aorta to provide access to an area adjacent the aortic valve.

Methods and systems for re-entering the true lumen of a vessel after subintimally bypassing an occlusion in a blood vessel. A guidewire is positionable within a subintimal tract in a wall of the blood vessel with a distal end located beyond the occlusion. A hollow lumen of the guidewire includes a retractable blade slidably exposable adjacent a distal end thereof for rotary cutting or scoring the intima layer of the vessel wall to create a transverse cut or line of weakness in the intima. A balloon catheter is subsequently trackable over the guidewire and once inflated tears or otherwise ruptures the transverse cut, thereby creating or enlarging a passageway into the true lumen of the blood vessel beyond the occlusion.
