Abstract: A wiggle catheter (a dilator) is disclosed to facilitate advancing catheters after puncturing a blood pathway, including without limitation navigation of noncompliant hardware through a diseased lumen. The wiggle catheter includes a proximal section, a distal section, and an intermediate section disposed between the proximal section and the distal section, the intermediate section may include a plurality of angulated kinks along the long axis of the catheter, the angulated kinks having substantially the same diameter at the outer edge of the kinks, said diameter of the outer edge of the kinks being substantially same as the inner diameter of an introducer sheath whereby the wiggle catheter may be positioned inside the introducer sheath with the outer edges of the kinks in close proximity to the inner surface of the introducer sheath. The wiggle catheter may also include a sinusoidal waveform like structure or a helical or spiral structure.

Abstract: Disclosed are methods and devices for obtaining patent hemostasis of the radial artery by compressing the uninstrumented ulnar artery to increase radial artery flow. The device comprises a band having an inflatable bladder for applying blunt pressure to the ulnar artery. The method comprises applying a pressure to the homolateral ulnar artery and applying a pressure to the radial artery at the access site to obtain hemostasis at the access site.

Abstract: A present invention method of obtaining patent hemostasis of the radial artery by compressing the uninstrumented ulnar artery to increase radial artery flow while applying pressure to the radial artery access site; the invention further concerns a device for applying blunt pressure to the ulnar artery, and a method of use.
