Medical device

Medical device

The invention relates to a medical device for placement in the body, in particular in a body vessel of a patient. The device includes a substrate ( 1 ), which is suitable for long-term placement, whose biocompatible properties have been modified by bombarding its surface ( 2 ) with foreign ions ( 3 ). The foreign ions ( 3 ) are thus embedded in the substrate ( 1 ) and form a boundary layer ( 5 ) that inhibits the diffusion of substrate ions ( 4 ) between the surface ( 2 ) and the interior ( 6 ) of the substrate ( 1 ).

Balloon catheter

The invention relates to a balloon catheter for the placement of stent grafts ( 1 ) with a proximal ( 7 ) and at least one distal balloon ( 8 ), a multi-lumen shaft ( 5 a ) having one lumen ( 6 ) sized to accommodate a guidewire and at least two lumina ( 5 a, 5 b ) for individually applying hydraulic pressure to the balloons, with lumina ( 5 b, 6 ) accommodating the guidewire and one or several distally arranged balloons ( 8 ) being passed through the proximal balloon ( 7 ) and the stent graft ( 1 ) being crimped onto the balloons ( 7, 8 ).
