    Abstract: A process for preparing coating compositions of a commingled hydrogel of a polyurethane-polyurea polymer hydrogel and a poly(N-vinylpyrrolidone) polymer hydrogel; a process for making materials composed of a polymeric plastic or rubber substrate or a metallic substrate, with a coating of the commingled hydrogel thereon; and a process for making medical devices with a coating of the commingled hydrogel thereon, are disclosed. The coating compositions tenaciously adhere to the substrate materials and medical devices to which they are applied due to bonding of a tie coat to a reactive substrate surface and due to the commingling of the two hydrogel components. The coating compositions and coated materials and medical devices are non-toxic and biocompatible, making them ideally suited for use in applications such as for catheters, catheter balloons and stents. In such applications, the coating compositions, coated materials, and coated medical devices made therefrom demonstrate low coefficients of friction in contact with body fluids, especially blood, as well as a high degree of wear permanence over prolonged use. The commingled hydrogel coatings are capable of being dried to facilitate storage of the devices to which they have been applied, and can be instantly reactivated for later use by exposure to water.

    Abstract: A system and method to position and orient an excised breast tissue specimen on a support structure in a duplicate anatomic orientation relative to the operated breast is provided. One embodiment of the system includes an anatomically representative map of the breast under investigation. The system allows a surgeon to suture, ink, or otherwise fix the excised specimen on the map in accordance to its original position and orientation in the operated breast or organ. A radiogram of the excised specimen can be taken that shows the location of calcifications on a grid with radiopaque markers. The system allows a pathologist to cut through the specimen utilizing the map as a template in order to perform histological analysis and correlate the position and orientation of each slice to its anatomic position in the breast and thereby direct a precise and anatomically accurate re-excision by the surgeon if so required.

    Abstract: Apparatus and methods are provided for applying a radially uniform radiation dose to an intravascular treatment region to inhibit hyperplanes, and specifically to reduce “candy-wrapper” ends, following intravascular intervention. An embodiment of the apparatus comprises a catheter body having a proximal end and a distal end, a pair of axially spaced apart radiation shields on the catheter body, and a radiation source. The radiation source applies a radiation dose which is substantially uniform in a radial direction over an entire distance between the axially spaced apart shields.
