A delivery system includes a rigid shaft, an imaging core, and an interventional core. The rigid delivery shaft has a proximal end, an angled distal tip, and an axial passage therethrough. The imaging core comprises an ultrasound imaging insert disposed within the axial passage. The imaging insert has an ultrasound array within a distal portion thereof, wherein the ultrasound array is tilted relative to a shaft axis. The interventional core comprises a curved ablation needle coupled to the rigid shaft. An angle of needle curvature may be inversely proportional to the ultrasound array tilt and tip angle.

The present invention involves systems and methods of linking a unique identifier with a package identifier to provide confirmation of the delivery of the package to a certain location or individual. The unique identifier may be associated with a location or an individual. In one embodiment, it is a barcode and the package identifiers are barcodes as well. The barcodes are scanned by a service provider using a hand-held data acquisition and storage device thereby linking the unique identifier to the package identifiers. The information is transferred from the hand-held device to a database where it is used to compile reports for and provide information to the service provider, the shipper, and the recipient of the packages. The invention may be incorporated into an inventory management system such that when confirmation of actual delivery has been received, the recipient will release payment to its vendors.
摘要:
Interventional catheter-based systems and methods are described herein for use in generating an initial pathway through vascular occlusions. The catheter systems generally include two elements. A first element is a Blunt Dissection Catheter including a manually actuated assembly located at the distal tip of the Blunt Dissection Catheter that performs blunt dissection in the vascular occlusion to produce a dissection track, or small pathway through the occlusion. The second element is a Sheath Catheter that serves as a conduit within which the Blunt Dissection Catheter is freely advanced, retracted and rotated. The first and second elements are used in some combination to cross vascular occlusions in both the coronary and peripheral vasculature.
