ADJUSTABLE VASCULAR RING, MEANS FOR TREATING SFS SYNDROME AND IMPLANTABLE KIT INCLUDING SAID RING, MOLD AND METHOD FOR OBTAINING SUCH RING.

摘要

The invention relates to a perivascular ring having an inner diameter adjustable by inflation/deflation and adapted to be implanted and closed about a vessel for controlling the inner diameter of said vessel and thus the flow and/or pressure of a fluid flowing in said vessel. The ring of the invention is capable of regulating blood flow to the liver, in particular after an hepatectomy or hepatic transplant, and to substantially improve the survival chances of the patient. The ring according the invention has an adjustable inner diameter (∠i) for implantation and locking about a vessel.

The WEB PROCESSING APPARATUSES, METHODS AND SYSTEMS provides for processing of web material, such as of tipping paper. An exemplary embodiment is an apparatus including a first roller component that manipulates a pair of tipping paper strips having a first lateral separation, where the pair of tipping paper strips traverse a first path. The apparatus further includes a second roller component that is located above the first roller component at a predefined height and has an orientation that is substantially perpendicular to the first roller component. The second roller component is configured to manipulate the pair of tipping paper strips traversing along the first path to a second path that returns the pair of tipping paper strips back to the first roller component. The pair of tipping paper strips returning to the first roller component include a second lateral separation. The apparatus comprises a drive configured to convey the web materials over the first and second set of rollers at speed between 3000-300 000mm/minute.
