1. A stent device for treating an aneurysm comprising:
an expandable balloon with a channel extending through said expandable balloon from one side to another; and
a supporting stent connected to said expandable balloon,
wherein the supporting stent is, in an operative disposition, arranged at least partly within said channel of said expandable balloon when said expandable balloon is expanded,
wherein said supporting stent has walls which are permeable to blood,
wherein the expandable balloon is connected to the supporting stent only at or adjacent to a proximal end of said supporting stent, and
wherein the expandable balloon, in an insertion disposition, is arranged within the supporting stent, and the expandable balloon is eversible into an expanded state outside said supporting stent in the operative disposition.
2. The stent device of claim 1, wherein a relative position between the expandable balloon and the supporting stent in an axial direction of the stent device is variable, and
wherein in the insertion disposition, the expandable balloon and the supporting stent are arranged in line with each other.
3. The stent device of claim 1, wherein the channel of the expandable balloon is arranged in a center of the expandable balloon when the expandable balloon has a torus shape in the expanded state.
4. The stent device of claim 1, wherein the supporting stent has a variable diameter, said diameter being remotely controllable.
5. The stent device of claim 1, wherein the supporting stent is self-expandable, and automatically strives to resume an expanded state after being released from a compressed state.
6. The stent device of claim 1, wherein the supporting stent is formed of threads arranged in at least two interfoliated spirals.
7. The stent device of claim 6, wherein ends of the threads forming the at least two interfoliated spirals extend beyond the supporting stent, whereby a diameter of the supporting stent is remotely controllable by varying tension of the extending ends of the threads.
8. The stent device of claim 1, wherein a diameter of the supporting stent in the operative disposition is less than 2 cm.
9. A kit for treating an aneurysm, comprising:
a delivery sheath; and
a stent device according to claim 1, wherein the delivery sheath releasably accommodates the stent device.
10. The kit of claim 9, wherein the expandable balloon, in the insertion disposition, is connected to the supporting stent at one end and to the delivery sheath at an opposite end.
11. The kit of claim 10, wherein the connection between the expandable balloon and the delivery sheath is releasable.
12. The kit of claim 9, wherein at least one of the stent device and the delivery sheath comprises markers visible by external observation.
13. The kit of claim 9, further comprising an extraction sheath for removal of the stent device from the aneurysm.
14. The kit of claim 12, wherein the markers are visible, by fluoroscopic vision.
15. A method for treating an aneurysm, comprising:
inserting the kit according to claim 9 into the aneurysm;
pulling back the delivery sheath, thereby releasing the stent device; and
expanding the expandable balloon in the aneurysm, wherein a fluid communication through the aneurysm is created through the channel in the expandable balloon.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A system for controlling a power sliding door of a vehicle, comprising:
a motor supplied voltage from a power source mounted on the vehicle for opening or closing the power sliding door;
a motor drive circuit for driving the motor having at least a switch for switching direction of rotation of the motor and a switching element for regulating the voltage to be supplied to the motor to change a speed of the motor rotation; and
a motor-drive-circuit controller for outputting a command value to the motor drive circuit.
2. A system according to claim 1, further including:
means for detecting an openingclosing speed of the power slide door;
and wherein the motor-drive-circuit controller regulates the voltage to change the speed of the motor rotation such that the power sliding door is opened or closed at a speed inversely proportional to the detected speed of the power sliding door.
3. A system according to claim 1, further including a branch which is connected to the ground through a diode such that the diode is connected with its anode on the ground side.
4. A system according to claim 2, further including a branch which is connected to the ground through a diode such that the diode is connected with its anode on the ground side.
5. A system according to claim 1, further including;
current detecting means for detecting supply of current to the motor; and
faulty operation detecting means for detecting that faulty operation has occurred in the motor-drive-circuit controller.
6. A system according to claim 5, wherein the faulty operation detecting means detects that the faulty operation has occurred in the motor-drive-circuit controller if the current detecting means detects the supply of current to the motor when predetermined outputs are supplied to the switch and the switch element.
7. A system for detecting faulty operation of a power sliding door of a vehicle, comprising:
a motor supplied voltage from a power source mounted on the vehicle for opening or closing the power sliding door;
a power-sliding door controller provided in a motor current supply circuit for supplying current to the motor having at least a switch for switching direction of rotation of the motor and a switching element for regulating the voltage to be supplied to the motor to change a speed of the motor rotation;
current detecting means for detecting supply of current to the motor; and
faulty operation detecting means for detecting that faulty operation has occurred in the power-sliding door controller.
8. A system according to claim 7, wherein the faulty operation detecting means detects that the faulty operation has occurred in the power-sliding door controller if the current detecting means detects the supply of current to the motor when predetermined outputs are supplied to the switch and the switch element.
