摘要：
There is disclosed a method and apparatus for harvesting tissue using a cannula having a diameter of from 0.5 to 4.0 mm and of a length of from 25 to 20 cm to access by minimally invasive techniques a host to withdraw autogenous tissue processed to remove loose fat and/or fragmented tissue. Thereafter, the resulting tissue substrate is morcellated to form particulate tissue of a particle size of from 1 to 200 .mu.m. The particulate material is thence passed through screens having opening sizes of from 1 to 100 .mu.m to form a material of a size for introduction into a syringe of from 16 to 30 gauge for implantation in the host. The processed tissue may be admixed with extenders, gelling agents and the like.
