Embodiment Construction

[0036] figure 1 The first embodiment of the device according to the invention for checking the function of the aortic valve 11 shown in , has a housing, generally designated with 1 , and a sealing device, generally designated with 7 , as essential elements.

[0037]In order to test the function of the aortic valve 11 , according to a first application, the device according to the invention is placed on the free end of a tubular graft 10 . The tubular graft 10 consists of plastic and is sutured at its lower end facing away from the upper free end to the end of the patient's dissected aorta. Furthermore, in this lower region there is additionally a vascular connection 25 to the cardiovascular system of the patient, which is likewise sutured to the tubular graft 10 during the entire operation. Both the vascular connection 25 and the connection between the tubular graft 10 and the aortic wall 26 must be designed absolutely liquid-tight.

Abstract

The invention relates to a device for testing the functioning of an aortic valve by placing the device on the free end of a cylindrical tubular prosthesis inserted into the aorta, said tubular prosthesis being connected, with its other end, to the aortic wall in the region of the aortic valve. According to the invention, the device consists of a multi-part housing provided with at least one through-flow channel for a control liquid, the housing being provided, on its lower side facing the free end of the tubular prosthesis, with a peripheral sealing device that can be placed around the edge ofthe tubular prosthesis, and at least one pressure-measuring sensor and at least one optical sensor element for video recording being arranged on the lower side.

Description

technical field [0001] The invention relates to a device for checking the function of the aortic valve, wherein the function of the aortic valve is checked by fitting the device over the free end of a cylindrical tubular graft inserted into the aorta, said tubular graft With its other end it is connected to the aortic wall in the region of the aortic valve. Background technique [0002] A device of the type mentioned at the outset is, to the applicant's knowledge, hitherto unknown in the prior art in the medical field. [0003] As a rule, in operations in the area of ​​functionally impaired aortic valves, a tubular graft inserted in a corresponding diameter dimension adapted to the patient's vessel diameter is sutured to the vessel wall and establishes a correspondence with the cardiovascular circulatory system. connect. [0004] The tightness of the connection established between the tubular graft and the body tissue is checked visually if all sutures have been completed ...
