摘要：
1. The catheter apparatus, comprising: a tubular housing having a distal end, a proximal end and a lumen formed by them and means for activation in order to selectively transfer the tubular body in a first state and a second state, wherein in the first state, the tubular body has a first stiffness value metric that is below a predetermined threshold for the passage and wherein in the second state the tubular body has a second stiffness value of the metric that is higher than a predetermined threshold zhestkosti.2. Catheter apparatus comprising: a tubular housing having a distal end, a proximal end and a lumen formed by them and means for activation in order to selectively transfer the tubular body in a first state and a second state, wherein in the first state, the tubular body has a first stiffness value of the metric, wherein in the second state the tubular body has a second stiffness value metric which is greater than the first value and wherein the activation means includes a controller communicatively coupled to the tubular body and adapted to place the tubular body to a second state, subjecting at least a portion of the catheter device temperatury.3 reduction or change.
