Abstract: A bathing apparatus related to the present invention provided with an open portion in a bag having a content volume that allows a bather to enter in addition to being provided with hoses which supply and discharge a bathing liquid at suitable locations of a bathing bag that is provided with open/close portions in succession from the edge of the open portion which can maintain a water tight state when the open/close portions are closed. The bathing apparatus is characterized by the bathing bag and hoses connected using joints comprised by a joint portion disposed in one direction being linkable to a joint portion disposed in another direction which form a water passing state when linked together and when not linked together at least one of the joints being in a water non-passing state.

Abstract: A microcatheter for infusion in which a tip portion of its shaft 2 comprises a porous tubular structure 3 having no communicating pores is provided. It can be inserted into fine peripheral blood vessels along a guiding wire and/or on a blood stream, and thus a contrast medium, a curative drug, an embolismic substance or the like can be infused in the desired portion.

Abstract: An artificial vessel having a compliance and a stress-strain curve approximate to those of a vital vessel, which comprises a porous part of an elastomer having pores which communicate between the inside of the vessel and the outside of the vessel and a tubular part of fibers, said tubular part being in contact with and/or bonded to at least one part of the porous part. The artificial vessel can be prevented from breakage and damage at a high blood pressure and has an excellent durability.

Abstract: An artificial vessel prepared from a solution of a thermoplastic elastomer in a good solvent, comprising a skin layer on at least the inner surface of the vessel wall, and an interior region having a spongy structure characterized by cells surrounded by partition walls, wherein the inner surface, outer surface, and partition walls contain:(a) small pores of less than 1 .mu.m in diameter formed by replacement of the good solvent in the solution of the elastomer with a coagulating liquid for the elastomer;(b) large pores of 1 to 50 .mu.m in diameter which are in continuous communication with each other and communicate the inner surface of the vessel wall to the outer surface of the vessel wall, the large pores being formed by elution of pore-forming particles contained in the solution of thermoplastic elastomer,and wherein the porosity of the artificial vessel is 75 to 87.5% by volume, and the compliance of the artificial vessel is 0.1 to 0.8.

Abstract: An artificial vessel, wherein the vessel wall is made of an elastomer having a porous structure with pores at any part of the vessel wall from the inner surface to the outer surface and consists of at least 2 concentric layers, each layer having a substantially uniform porosity percentage, the inmost layer having a thickness of from 30 to 500 .mu.m and a porosity percentage of from 95 to 80% and other layers having a lower porosity percentage than that of the inmost layer, and the porosity of the whole vessel wall is from 90 to 75%.The artificial vessel may also be reinforced with tubular material made of fiber or with heat-set tubular material made of fiber.The artificial vessel of the present invention has a porosity, a compliance approximate to that of a vital vessel, and a contact surface with blood having an excellent blood compatibility.

Abstract: A heat resistant resin composition comprising a, polyamide imide resin having carboxyl groups and modified with an N-methylolated methacryl- or acryl- amide compound and, when desired, further with a bismaleimide compound. The composition has improved properties over conventional polyamide imide resins. When the composition is used, for example, in the form of a film for printed circuit boards, the film has improved heat resistance and enhanced flexural strength and is capable of withstanding soldering baths at high temperatures.
