Steerable sheath assembly and methods of making a steerable sheath

A steerable sheath assembly, comprising:

• an inner tubular sleeve;
• at least one tubular member positioned alongside the inner tubular sleeve;
• a reinforcing braid disposed over the inner tubular sleeve and the at least one tubular member;
• an outer tubular sleeve disposed over the reinforcing braid;
• and
• a proximal hub structure overmolded onto the outer tubular sleeve;
• wherein the proximal hub structure comprises a separate lumen extending from each tubular member of the at least one tubular member through a distal portion of the proximal hub structure to an exterior of the proximal hub structure at a location distal of a proximal end of the proximal hub structure.

A method of making a steerable sheath assembly, comprising:

• positioning an inner tubular sleeve on a mandrel;
• disposing at least one tubular member alongside the inner tubular sleeve, each tubular member of the at least one tubular member having a core wire disposed therein;
• disposing a reinforcing braid over the inner tubular sleeve and the at least one tubular member;
• disposing an outer tubular sleeve over the reinforcing braid;
• and
• overmolding a proximal hub structure onto a proximal end of the outer tubular sleeve and a proximal portion of each tubular member of the at least one tubular member;
• wherein the proximal portion of each tubular member of the at least one tubular member extends through a distal portion of the proximal hub structure to an exterior of the proximal hub structure at a location distal of a proximal end of the proximal hub structure.
