Device and method for opening blood vessels by pre-angioplasty serration and dilatation of atherosclerotic plaque

ActiveUS20090240270A1Safely and accurately dilated and stretchedDilated more evenly and smoothlyBalloon catheterCannulasBlood vessel spasmPercutaneous angioplasty
A device and method for intravascular treatment of atherosclerotic plaque perforates the plaque with microperforations by small sharp spikes to act as serrations for forming cleavage lines or planes in the plaque. In preferred embodiments, expansion may be obtained by mechanical apparatus, expansion balloon, or balloon-assisted deployment. The plaque treatment enables a subsequent balloon angioplasty to be performed without creating substantial dissections and at low balloon pressure so as to avoid injury to the arterial wall. The plaque treatment may include dilatation of the plaque at low pressure, sufficiently that no subsequent balloon angioplasty is needed. The plaque preparation may be followed by applying one or a few ring tacks to secure the compressed plaque with minimal emplacement of foreign material.

Hospital day gown

A hospital gown closes along the side and across the rear of the shoulder of the person wearing the gown. The side closure combined with different arm closures allows the gown to be used by the patient and the medical staff in different ways. The gown can be placed onto the patient without requiring the patient to sit up. The gown can be draped over the patient like a blanket. The gown can be removed from a patient while the patient is lying down in bed. The side opening of the gown allows the gown to be placed over a patient who is lying on his back without immediately wrapping the gown around the patient's body. When the patient is up and walking, the side closure and a long waist tie provide modesty.
