摘要： A vasculature occlusion device detachment system including a heating element of a predetermined resistivity. A coil securing suture terminates in a proximal bead retained within the heating element while the distal end of the coil securing suture extends beyond the distal end of the heating element and is attached to the proximal end of the vasculature occlusion device. The coil securing suture is independently rotatable of the heating element 360 degrees about a longitudinal axis extending therethrough the heating element. A power source applies electrical current to the heating element via an electrically conductive corewire and separate insulated electrically conductive wire to increase its resistance and, as a result of the heat produced, sever the coil securing suture.

摘要： An endovascular surgical tool includes a flexible, electrically-conductive corewire, a return conductor, a resistive heating element attached to the distal end of the corewire, and a therapeutic payload attached to the loop of the resistive heating element by a coil connecting member. The corewire includes at least one segment at its distal end which transitions from the substantially uniform cross-section of its proximal end to a smaller distal cross-section. The return conductor is electrically insulated from and bonded to the corewire. The resistive heating element includes a first terminal electrically connected to the corewire, a second terminal electrically connected to the return conductor, a helical coil, and a loop. The helical coil and the loop are electrically in series between the first terminal and the second terminal. The coil connecting member has a release temperature lower than a loop melting temperature of the loop of the resistive heating element.

摘要： A balloon guide catheter 100a having a substantially tubular body 115, an inflation lumen 117, and a balloon 113. The tubular body can include an inner hollow lumen 114 and a distal end. The inflation lumen can have a distal end and a proximal section. The distal end of the inflation lumen can be in connection with the tubular body approximate to the distal end of the tubular body. The proximal section of the inflation lumen can extend a majority of the length of the tubular body and can be moveable in relation to the tubular body. The inflation lumen can be positioned within an inner hollow lumen of a tubular body of the catheter or external to the tubular body, thereby enhancing flexibility of the catheter.

摘要： A vasculature occlusion device detachment system including a heating fuse element made of a material that melts when a current is applied that exceeds a predetermined maximum current threshold. An electrically conductive corewire connected proximate its distal end directly to the heating fuse element at a first electrical connection joint, while a separate insulated electrically conductive wire is electrically connected directly to the heating fuse element at a second electrical connection joint. An inner insulation sleeve placed over a distal section of the corewire covers the first electrical connection joint and is disposed between the insulated electrically conductive wire and the electrically conductive corewire. An outer insulation sleeve is disposed over a distal section of an assembly including the insulated electrically conductive wire, the inner insulation sleeve and the electrically conductive corewire. The outer insulation sleeve covers the second electrical connection joint.
