Title: Formulations limiting spread of pulmonary infections
Inventor: STONE HOWARD A
IPC: A61K31/355
Filed: 2003-05-01
Abstract: Formulations have been developed for pulmonary delivery to treat or reduce the infectivity of diseases such as viral infections, especially tuberculosis, SARS, influenza and respiratory synticial virus in humans and hoof and mouth disease in animals. Formulations for pulmonary administration include a material that significantly alters physical properties such as surface tension and surface elasticity of lung mucus lining fluid, which may be a surfactant and, optionally, a carrier. The formulation may be administered as a powder where the particles consist basically of the material altering surface tension. The carrier may be a solution, such as an alcohol, although an aqueous solution may be utilized, or a material mixed with the material altering surface tension to form particles. These may include proteins such as albumin or polysaccharides such as dextran, which also has surface active properties, or polymers such as polyethylene oxide (PEO) or biodegradable synthetic polymers which can be used to encapsulate or deliver the materials to be delivered. Drugs, especially antivirals or antibiotics, may optionally be included with the formulation. These may be administered with or incorporated into the formulation.

Title: Elastomerically recoverable eptfe for vascular grafts
Inventor: SOWINSKI KRZYSZTOF
IPC: A61L27/00
Filed: 2003-05-01
Abstract: This invention relates to an elastomerically recoverable PTFE material that includes a longitudinally compressed fibrils of ePTFE material penetrated by elastomeric material within the pores defining the elastomeric matrix. The elastomeric matrix and the compressed fibrils cooperatively expand and recover without plastic deformation of the ePTFE material. This invention was used for various prosthesis, such as vascular prosthesis like a patch, a graft and an implantable tubular stents. Furthermore, this invention discloses a method of producing the elastomerically recoverable PTFE material which include the steps of: providing the specified ePTFE, defined by the nodes and fibrils, to meet the desired end use; longitudinally compressing the fibrils of the ePTFE, the pore size sufficiently enough to permit penetration of the elastomeric material; applying the elastomeric material within the pores to provide a structurally integral elastomerically recoverable PTFE material defining an elastomeric matrix. The elastomeric material is applied to the ePTFE by dip, brush or spray coating techniques. The compression step and the application steps are interchangeable to produce the desired properties for the end use material. Finally, the elastomeric material is dried within the pores of the longitudinally compressed ePTFE to solidify the elastomeric matrix.

Title: Partial fragmentation and deformation bullets having an identical point of impact
Inventor: SCHIKORA IRENE
IPC: F42B12/34
Filed: 2003-04-30
Abstract: Especially in hunting, the choice of bullets has to be such that it is in keeping with the wild animals to be hunted. According to the desired effect on the target, deformation bullets or partial fragmentation bullets are used.  Since both types of bullets are different, the position of the point of impact from the same weapon is different. According to the type of bullet used, the weapon must be oriented differently in relation to the target. This can be obstructive and if insufficient attention is paid, can result in misses.  According to the invention, a shell-less cored steel bullet is used as a deformation bullet (1) or partial fragmentation bullet (2), having an identical caliber and a closed cavity (4) in the tip (3) of said bullet. In order to achieve the same point of impact of said bullets (1,2) on the target, while maintaining the effect of the respectively selected bullet during the same handling of the weapon, during the same setting of the target in an identical position, the external volume, centre of gravity, mass and base copper-tin alloy are identical and the cavity (E) in the tip (3) of the bullet, consisting of a combination of cylindrical and conical sections (10, 12, 13; 20), in addition to the composition of the bullet material, are adapted to the effect of said bullet.
