摘要:
The implant includes an outer layer of ePTFE which exhibits extensibility normally not associated with ePTFE. The ePTFE is reduced in length by deforming the fibrils between the nodes while maintaining the nodes in a substantially flat configuration. Various implant configurations that can include the outer layer described are also disclosed.
摘要:
A catheter is usable to treat a hollow anatomical structure (HAS). The catheter comprises one or more shafts which extend away from a proximal end of the catheter toward a distal end thereof. The catheter further comprises an HAS constriction energy source located at or near the distal end of the catheter. The catheter further comprises at least one radially expandable transmural fluid delivery channel located in the catheter near the HAS constriction energy source.
摘要:
A liquid transfer connector comprises an enclosure holding a transfer needle and an exhaust needle. A container of donor liquid may be attached to an inlet end of the transfer needle and a container holding a recipient liquid may be attached to an outlet end of the transfer needle and an inlet end of an exhaust needle. The exhaust needle has an outlet end within the connector which releases displaced fluid into an absorbent mass which sequesters the fluid to prevent leakage.
