The invention provides for delivery, engineering and optimization of systems, methods, and compositions for manipulation of sequences and/or activities of target sequences. Provided are delivery systems and tissues or organ which are targeted as sites for delivery. Also provided are vectors and vector systems some of which encode one or more components of a CRISPR complex, as well as methods for the design and use of such vectors. Also provided are methods of directing CRISPR complex formation in eukaryotic cells to ensure enhanced specificity for target recognition and avoidance of toxicity and to edit or modify a target site in a genomic locus of interest to alter or improve the status of a disease or a condition.

Delivery, use and therapeutic applications of the CRISPR-Cas systems and compositions for HBV and viral diseases and disorders

The present invention relates to a catheter that has adjustable stiffness that enables a user to select the stiffness of at least one region of the catheter during insertion and navigation through a body lumen. A preferred embodiment of the invention works in combination with a guidewire to enable placement of the catheter at a position within the vascular system, for example, to enable treatment of a variety of medical conditions. The catheter can include segments that undergo relative movement in response to actuation by the user to adjust the flexibility of the at least one region, preferably located at or near the distal end of the catheter.
