INTRODUCER SHEATH WITH BRAIDED FILAMENT SECUREMENT MECHANISM

摘要

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.

主权项

1. A method for manufacturing a tubular body for a medical device, comprising:
applying solder to a circumferential region of a braided member for an axial length, wherein the braided member includes a plurality of intersecting filaments and a plurality of cells defined by the intersecting filaments, wherein the solder rigidly fuses portions of the intersecting filaments and spans the cells, wherein an outer surface of the braided member is positioned at or beyond an outer surface of the securement mechanism; positioning the braided member over at least a portion of an inner liner tube; and securing an outer layer tube over the inner liner tube and the braided member.
