A fixing device capable of being fixed, by simple fixing, to a living body without causing an occurrence of inflammation is provided. The fixing device 3 is fixed beneath the skin of the living body and includes a porous portion 31a capable of inducing cells thereto and a flat portion 31b that allows the cells to be adhered thereto, the porous portion 31a and the flat portion 31b are provided adjacent to each other, and a virtual surface SF1 of the porous portion 31a and a surface SF2 of the flat portion 31b are substantially flush with each other.

The present disclosure provides medical devices, systems and methods and in particular to devices and methods useful for anchoring graft materials to bodily structures.

An apparatus for protecting heart tissue from an implanted inlet element of a blood pump. The apparatus includes a flange member having a first radially constricted configuration and a second radially expanded configuration, the flange member being biased in its second radially expanded configuration. The flange member defines an opening there through sized to receiving the inlet element of the blood pump. A retaining element extending from the flange member is included, the retaining element being flexible and sized to be disposed about at least a portion of the inlet element.

A dual lumen drainage cannula configured for use in a veno-arterial extracorporeal membrane oxygenation (VA ECMO) system includes a first drainage tube having a proximal end, a distal end, and at least one aperture defined in the distal end. The dual lumen drainage cannula further includes a second drainage tube having a proximal end, a distal end, and at least one aperture defined in the distal end. The dual lumen drainage cannula further includes an outlet fitting in fluid communication with the first drainage tube and the second drainage tube. The distal end of the second drainage tube is joined to a portion of the first drainage tube between the proximal and distal ends of the first drainage tube.

A blood pump for supporting a patient's heart includes a flow cannula having a distal portion including a distal end and a proximal portion including a proximal end opposite the distal end, the distal end of the flow cannula configured to be connected to the patient's heart or a blood vessel to establish fluid communication between the blood pump and the patient's heart and blood vessel, respectively. The flow cannula further includes an intermediate portion attached to the distal portion and the proximal portion, wherein the intermediate portion allows twisting thereof with a lower force than the distal portion and the proximal portion. The intermediate portion can be fully occluded by twisting it. At least a portion of the intermediate portion either alone or in combination with the distal portion is adapted to be permanently attached to the patient's heart or a blood vessel.

A vascular coupling device (10), comprising a first and a second coupling element (21, 22) wherein each one of said first and second coupling elements (21, 22) has an external surface (23′, 23″) facing an external side, a coupling surface (25′, 25″) facing a coupling side, a central opening (27′, 27″), and a first and a second tubular connecting element (31, 32). Each one of said first and second tubular connecting elements (31, 32) is arranged in a corresponding central opening (27′, 27″) of the first and second coupling elements (21, 22) respectively, and with second open ends (37, 38) protruding through said central openings (27′, 27″) on said external side of each of said first and second coupling elements (21, 22). The first and second coupling elements (21, 22) being removably connected to each other into a locked configuration, or disconnected from each other into an unlocked configuration by means of a first and second locking structure (41, 42) being arranged on a centerline A and opposite to each other on an outer perimeter of said vascular coupling device (10). The vascular device further comprises a fail-safe arrangement comprising first and second cut-in portions (91, 92) arranged on said first coupling element (21) configured to receive first and second projecting elements (93, 94) arranged on said second coupling element (22), thereby preventing erroneous connection of said first and second coupling elements (21, 22) to each other.
