Abstract: A covered vascular filter can be placed in a blood vessel, for the purpose of intercepting thrombus. The filter may be introduced to a desired site for medical treatment through a catheter which defines a lumen or passage and a distal port or opening. The filter tends to resiliently expand from a compressed shape when it is inside the catheter lumen, to an expanded shape when the filter is pushed from the catheter lumen. A cover or sleeve over those portions of the filter that would otherwise contact the vessel wall tends to reduce pressure on the vessel wall. The sleeve also tends to resist growth of the vessel wall among the elements of the filter, called endothelialization. In other words, the sleeve resists incorporation of the filter elements into the vessel wall, enabling the filter to be retrievable for a longer time. The various features of the present invention may be used singly or in any combination, as desired in a particular vascular filter.

Abstract: The present invention relates to a safety cartridge for a medical filter which can be inserted through a percutaneous access point, via a catheter or introducer, and placed in a blood vessel or other body passage. Filters may have features which are not longitudinally symmetrical, such as anchors or barbs which angle toward one end, or a retrieval hook at only one end. Depending on the physician's selection of the access point, the filter may be introduced to a desired site for treatment from opposing directions. However, it is desirable to introduce the filter with the desired alignment (inserting the desired end in first) regardless of where the selected access point is, and accordingly regardless of which direction of approach to the desired site. As a result, it is desirable to provide a safety cartridge. Cartridges hold filters in an initial compressed shape during storage and insertion into the patient.

Abstract: Certain organic compounds derived from urea or thio-urea having insectical activity and methods of their preparation are disclosed. The compounds according to the invention have been found to interfere with the mechanism of metamorphoses which occurs in insects. Hence, the substances according to the invention are specifically active against insects. Owing to this specificity and because of the absence of phytotoxicity effects, the compounds of this invention are of prime importance.

Abstract: Benzoyl phenyl urea or thiourea derivatives are used as active substances in insecticidal compositions.

Abstract: It has been found that novel pyrazoline compounds have a strong and specific biocidal activity against arthropods and especially insects. In addition to their more direct biocidal activity the novel compounds influence the pattern of motion of arthropods, which results in uncoordinated movements. A highly active substance is, for example, 1-(4-chlorophenylcarbamoyl)-3-(4-chlorophenyl)-5-(4-isopropoxyphenyl)-.DEL TA..sup.2 -pyrazoline. After the substances have been worked up into preparations they can be used for controlling arthropods and especially insects which are pests in agriculture and horticulture and in industrial products.
