摘要:
The present invention relates to a stabilizer composition for weather-resistant halogen-containing thermoplastic resin compositions, in particular based on PVC. The stabilizer composition according to the invention contains at least one natural or synthetic hydrotalcite, at least one basic calcium-aluminum-hydroxy compound, selected from basic calcium-aluminum-hydroxy-phosphites and basic calcium-aluminum-hydroxy-carboxylates, and at least one polyol and/or at least one hydroxy group-containing isocyanurate.
摘要:
The present invention relates to a stabilizer composition for halogen-containing thermoplastic resins, the stabilizer composition comprising (a) calcium hydroxide and/or calcium oxide which may optionally be surface-modified; and (b) a hydroxyl group-containing isocyanurate. This stabilizer composition is particularly suited for weather-resistant halogen-containing resin compositions, such as rigid PVC.

摘要:
A catheter for delivering a therapeutic or diagnostic agent to a branch blond vessel of a major blood vessel comprises an elongated shaft having at least one lumen in fluid communication with an agent delivery port in a distal section of the shaft, an expandable tubular member on the distal section of the shaft, and a radially expandable member on the tubular member. The tubular member is configured to extend within the blood vessel up-stream and down-stream of a branch vessel, and has an interior passageway which is radially expandable within the blood vessel to separate blood flow through the blood vessel into an outer blood flow stream exterior to the tubular member and an inner blood flow stream within the interior passageway of the tubular member.

Two renal delivery members have two distal ports that are adapted to be positioned within two renal arteries via their corresponding renal ostia at unique locations along an abdominal aortic wall. A proximal coupler assembly is outside the body and is coupled to deliver material to the two distal ports for bi-lateral renal therapy. One or both of the delivery members may be self-cannulating into the corresponding renal ostium, or may be controllably steered into the respective ostium. Non-occlusive anchors may be coupled with one or both of the delivery members at anchoring positions in the renal artery or abdominal aorta to secure the renal delivery member within the renal artery. Renal-active fluid agents are coupled to the bi-lateral delivery system. Another renal therapy system cannulates a renal vein from the vena cava and controls a retrograde delivery of agents to the respective kidney.
