DEVICES FOR PREVENTING TISSUE ADHESION. |
摘要 |
A device for preventing adhesions or binding of tissue to tissue or of tissue to bone which comprises a composite of a first layer and a second layer, each of which comprises a biodegradable polymer. The first layer is selected from the group consisting of a non-porous layer and a porous layer having a pore size no greater than 3 mu . The second layer has pores which have a pore size of from about 30 mu to about 250 mu . Such a composite device provides for tissue growth into the second layer, while the first layer acts as an adhesion-preventing barrier, and enables attachment of the device to tissue without suturing. Alternatively, the device comprises the first layer hereinabove mentioned and a second layer which is an adherence layer and which adheres to tissue and/or bone. |
