Abstract
A tubular body for a medical device for insertion within a body passageway of a patient. The tubular body includes a tubular inner liner. A braided member is disposed along an outer surface of the liner. The braided member includes intersecting filaments and cells defined by the filaments. A securement mechanism, such as radiopaque solder, is disposed along a circumferential region of the braided member. The securement mechanism is attached to portions of the filaments and spans the cells that correspond to the circumferential region to inhibit relative movement of filament ends. An outer surface of the securement mechanism is sized to extend radially outward to a position up to an outer surface of the braided member to not add to the overall wall thickness of the tubular body. An outer jacket is positioned longitudinally around the braided member and connected to the inner liner.
