1. A storage apparatus for storing data comprising:
a backup processing unit that stores data stored in a first memory into a second memory as backup data upon occurrence of a power failure;
a restore processing unit that upon recovery from the power failure restores the backup data backed up in the second memory to the first memory and erases the backup data stored in the second memory; and
an erasure processing termination unit that, upon a power failure occurring during erasure processing for erasing the backup data stored in the second memory, terminates the erasure processing; and
a re-backup processing unit that re-backs up data in the first memory corresponding to the backup data erased from the second memory before the erasure processing is terminated by the erasure processing termination unit to a location in the second memory subsequent to a last location that contains the backup data which has not been erased by the erasure processing.
2. The storage apparatus according to claim 1, wherein the restore processing unit restores the backup data stored by the backup processing unit after restoring of the backup data re-backed up by the re-backup processing unit is completed.
3. The storage apparatus according to claim 2,
wherein, subsequent to restoring of the backup data including the re-backed up backup data, upon a power failure occurring during execution of erasure processing executed by the restore processing unit, the erasure processing termination unit terminates the erasure processing, and
wherein the re-backup processing unit re-backs up data in the first memory corresponding to the backup data erased from the second memory before the erasure processing is terminated by the erasure processing termination unit to a location in the second memory subsequent to a last location that contains the re-backed up data which has not been erased by the erasure processing.
4. A method of backing up in a storage apparatus, the method comprising:
storing data stored in a first memory into a second memory as backup data upon occurrence of a power failure;
restoring, upon recovery from the power failure, the backup data backed up in the second memory to the first memory and erasing the backup data stored in the second memory;
terminating, upon a power failure occurring during erasure processing for erasing the backup data stored in the second memory, the erasure processing; and
re-backing up data in the first memory corresponding to the backup data erased from the second memory before the erasure processing is terminated in the terminating operation to a location in the second memory subsequent to a last location that contains the backup data which has not been erased by the erasure processing.
5. The method of backing up in a storage apparatus according to claim 4, wherein in the restoring operation the backup data stored in the backing up operation is restored after restoring of the backup data re-backed up in the re-backing up operation is completed.
6. The method of backing up in a storage apparatus according to claim 5,
wherein subsequent to restoring of the backup data including the re-backed up backup data, upon a power failure occurring during execution of erasure processing executed in the restoring operation, the erasure processing is terminated, and
wherein in the re-backing up operation data in the first memory corresponding to the backup data erased from the second memory before the erasure processing is terminated in the erasing operation is re-backed up to a location in the second memory subsequent to a last location that contains the backup data which has not been erased by the erasure processing.
7. A method of backing up in a storage apparatus, the method comprising:
terminating, upon a power failure occurs during erasure processing of stored backup data, the erasure processing; and
backing up data corresponding to erased backup data before the erasure processing is terminated to a location in a memory subsequent to a last location that contains backup data that was not erased by the erasure processing.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An endovascular delivery system comprising:
a stent delivery catheter, and
an imaging catheter,
wherein one of the stent delivery catheter or the imaging catheter is received within the other.
2. The delivery system of claim 1, wherein the imaging catheter is received within the stent delivery catheter.
3. The delivery system of claim 2, wherein the stent delivery catheter is adapted to deliver an implantable valve comprising a stent frame.
4. The delivery system of claim 3, wherein the implantable valve and stent delivery catheter is adapted for transcatheter aortic valve replacement (TAVR) applications.
5. The delivery system of claim 1, wherein the imaging catheter is an ultrasound imaging catheter.
6. The delivery system of claim 1, wherein the stent delivery catheter and an imaging probe of the imaging catheter are set at a fixed position relative to each other.
7. The delivery system of claim 1, wherein the stent delivery catheter and an imaging probe of the imaging catheter are free to move relative to one another in the delivery system, wherein the relative position between the stent delivery catheter and the imaging probe is tracked.
