Abstract
A device for locating a puncture hole in a liquid-carrying vessel such as a blood vessel comprises a hollow tube 92 having front and rear openings respectively at opposite ends of the tube to allow the tube to slide along a guidewire passing through the tube. The front opening 96 comprises a first portion 96A for slidably accommodating the guidewire and a second portion 96B to allow liquid from the vessel to flow back through the tube. The device is configured, e.g. by a constriction 96C, such that a guidewire at least above a certain diameter in the first portion 96A of the front opening is restrained against moving into the second portion 96B. Alternatively, the first and second portions 96A, 96B of the front opening may be independent of one another.
