Method of controllably directing a device into a human vessel

摘要

A method of controllably directing an elongate device into a vessel network including the steps of: obtaining a tubular component with a tubular wall bounding a passageway and having an aperture between spaced ends; directing an introducing member into the vessel network towards a target site; placing the introducing member and tubular component in an operative relationship wherein at least a portion of the introducing member resides within the passageway; relatively repositioning the introducing member and tubular component by guided movement, one against the other, to place the aperture at an introduction location; and directing the device through the passageway to and through the aperture to the target site.

1. A method of controllably directing an elongate device into a vessel network in a human body to access a predetermined target site, the method comprising the steps of:
obtaining a tubular component comprising a tubular wall with a length between spaced ends, the tubular wall bounding a passageway and having an aperture between and spaced from each of the spaced ends; obtaining an introducing member; directing the introducing member into the vessel network towards the target site; placing the introducing member and the tubular component in an operative relationship wherein at least a portion of the introducing member resides within the passageway; relatively repositioning the introducing member and tubular component by guided movement, one against the other, to place the aperture at a predetermined introduction location within the vessel network; and directing the elongate device through the passageway to and through the aperture to the target site.
