Intravascular device with an improved attachment of its elements and a method of manufacturing thereof

An intravascular device, comprising:

• a vascular catheter comprising a catheter jacket, an inner catheter element surrounded by the catheter jacket, and a distal connection portion, the distal connection portion comprising an extended portion of the inner catheter element extending distally beyond a distal end of the catheter jacket, and the inner catheter element comprising a first element and a second element, both being concentrically disposed within the catheter jacket;
• a tool attached to, and extending from, the distal connection portion of the vascular catheter, the tool comprising a proximal connection portion, wherein a proximal end of the proximal connection portion of the tool abuts a distal end of the second element, wherein the first element is disposed within the second element;
• and
• an attachment between the tool proximal connection portion and the vascular catheter distal connection portion adapted to keep the tool connected to the vascular catheter, the attachment having an outer diameter substantially equal to an outer diameter of the vascular catheter.
