Abstract: Devices, systems, and methods are disclosed that help deliver catheters or other medical devices to locations within a patient's body. The device comprises a transporter catheter having a proximal end and a distal end, at least a first balloon located at the distal end, substantially at a tip of the transporter catheter, and at least a second balloon located between the distal end and the proximal end of the transporter catheter. The first balloon is an orienting balloon and the second balloon is an anchor balloon. The transporter catheter may include a single lumen or more than one lumen. The transporter catheter may include a shaft comprising an inner layer and an outer layer, the inner layer may be made of a material more flexible than the material of the outer layer. The outer layer may also comprise a braided wire assembly, said braided wire assembly being formed by braiding a plurality of flat wires or circular wires. The braided wire assembly may wrap around the inner layer.

Abstract: Devices, systems, and methods are disclosed that help deliver catheters or other medical devices to locations within a patient's body. The device includes a transporter catheter having a proximal end and a distal end, at least a first balloon located adjacent to the distal end, and at least a second balloon located between the first balloon and the proximal end of the transporter catheter.

Abstract: A hemostatic device is provided to stop bleeding at a puncture site on an artery of a patient, the device comprising a transparent flexible band to be wrapped at the site where the bleeding is to be stopped, a curved compression member having an inner peripheral side and possessing a first curved portion in its first half and a second curved portion in its second half, a first balloon provided on the inner peripheral side in the first half of the curved compression member and a second balloon provided on the inner peripheral side in the second half of the curved compression member. The bleeding from a first artery is stopped by compressing the first artery at the puncture site using inflation of the first balloon and blood flow in the first artery is increased by compression of a second artery using inflation of the second balloon.

Abstract: An introducer sheath is provided to facilitate placement of two or more catheters in a patient's vasculature. The introducer sheath includes at least one internal partition thereby providing at least two lumens and the at least one internal partition is made of an elastic material. The internal partition may be made of materials such as polyurethane, silicone, or thermoplastic polymer. The internal partition may also have an expandable fold. The wall of the sheath may also have an expandable fold. An exemplary procedure where an introducer sheath of the present invention may be used is percutaneous coronary intervention on chronic total occlusion in a coronary artery. The introducer sheath of the present invention may also be used to deliver an implant mounted on a catheter.
