Claims3
A method of producing a bioabsorbable membrane, the method comprising:
- forming a liquid membrane by spin-coating a coating liquid containing a first bioabsorbable polymer and a solvent;
- and
- forming a dense layer by causing a porous membrane containing a second bioabsorbable polymer to contact the liquid membrane.
A bioabsorbable membrane comprising:
- a dense layer containing a first bioabsorbable polymer;
- and
- a porous membrane containing a second bioabsorbable polymer,
- wherein the dense layer has an average thickness of 10 μm or more and 500 μm or less, and a percentage of an average deviation of thicknesses to the average thickness is 20% or less.
