The invention refers to endovascular catheters and methods useful to endovascular surgery. In particular, it refers to support catheters with balloons that are used for the placement or the forwarding of the guidewire through demanding tortuosity and important vascular stenoses in cases where the guidewire needs the best possible backup support of the catheter. This is achieved with the development of an endovascular support catheter with a mobile balloon, which has the ability to move along the body of the catheter, at its distal part. The movement of the balloon is achieved with the use of two mobile external rings, one inner wire circuit, and one control handle which is found at the proximal end of the device. The mobile balloon allows the catheter to move inside the vessel even when it is inflated and basically anchored within the vessel.

The present invention discloses a device for the collection and scavenging of biological samples, and drug delivery for upper and lower respiratory tracts and hollow organs. The device comprises a distal balloon assembly (101) comprising distal carrier disc (101a) and a distal balloon (102), a proximal balloon catheter assembly (103) comprising proximal carrier disc (103a) and a proximal balloon (104), an inflation tube (108), a double lumen catheter (105) with an outer tube (105a) and an inner tube (105b), an agitator (106) working by methods such as ultrasonication, vibration, rotation, to-and-fro movements, pulsations etc, a flexible rod (107) to mount the agitator (106). Thus, the invention provides the device or a catheter with balloons to isolate pathogens or viruses from nasal cavity, nasopharynx, or relevant segment of hollow organs, with or without the use of water or similar liquids.

The balloon catheter of the present invention is provided with a balloon base at a front end of a tubular catheter body having a predetermined length. The balloon base includes a cylindrical base having a larger diameter than an outer diameter of the catheter body, and a lumen having substantially the same diameter as the outer diameter of the catheter body is formed on the base over an entire length with both ends opened. A central axis of the lumen is inclined at a predetermined angle with respect to a central axis of the base concentric with a central axis of the catheter body, and an outer peripheral surface is formed in parallel with the central axis of the base. The balloon is provided on the outer peripheral surface of the parallel base to obliquely inflate with respect to the central axis of the catheter body during inflation.
