Abstract: This application relates to a device for the local delivery of a substance to a mammary duct by ductal cannulation via an orifice on a nipple, wherein the substance may any substance or combinations of substances, such as for example, compositions capable of forming a solid or semisolid gel within the ducts, a marker, and/or an active agent which is preferably effective in treating and/or preventing breast cancer. More particularly, a device is disclosed comprising a probe for locating the orifice on the nipple, wherein the device is further configured to cannulate the duct and allow local delivery of a substance(s).

Abstract: A hollow medical device includes a coil member having a distal end, a proximal end, a plurality of turns extending therebetween, and a lumen extending through the turns. The coil member further includes at least one weld extending from one turn to an adjacent turn.

Abstract: A catheter includes a distal end, a proximal end, an outer tube extending from the distal end to the proximal end, and an inner tube extending through the outer tube. The distal end including a corrugated section attached to an end of the inner tube and an asymmetric balloon attached to the outer tube and configured to deflect the distal end of the catheter.

Abstract: A guidewire extension assembly for use in angioplasty to facilitate exchanging a balloon dilitation catheter that includes a guidewire and an extension wire that are releasably connected thus avoiding the need to use a separated exchange wire. The proximal end of the guidewire and the distal end of the extension wire either have one or more slots or one or more keys and when joined together cream a guidewire extension system utilizing a keyed joint connection. The key, when inserted in the slot, is held in place by frictional engagement to connect the distal end of the extension wire to the proximal end of the guidewire. The keyed connection between the guidewire and the extension wire makes it simple to attach the wires together, transfers torsional forces between the wires without the fear of the wires coming apart or unscrewing and is readily disconnected/reconnected when required.
