Title:
POLYMER COMPOUND FOR MEDICAL USE AND COMPOSITION AND DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/146897
Kind Code:
A1
Abstract:
Provided are: a polymer compound capable of suppressing activation of the coagulation system, the complement system, or the platelet system when brought in contact with in vivo tissue and/or blood, as a result of being capable of containing intermediate water; and a composition and a device that use same. The polymer compound includes a repeated unit indicated by general formula (A), is used in contact with in vivo tissue and/or blood, and is characterized by having a temperature range of -80°C to -25°C in which heat is generated and by having a temperature range of at least -25°C and less than 0 °C in which heat is absorbed, in a step in which the polymer compound having been hydrated at a prescribed hydration rate is cooled to -100°C then heated at a temperature increase of 5.0°C/min. (In the formula, R indicates a C1-20 hydrocarbon group.)
