It means that the tissue removed during the D&C represented some of the tissues you'd find during a pregnancy, but there's no mention of an embryo.
Chorionic villi are of fetal origin and eventually form the placenta
A chorionic villi sampling can be performed as early as week 10 of the pregnancy.
The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta. APEX~ a few days after fertilization

Chorionic villi & Decidua Basalis

Amniocentesis and chorionic villi sampling.
The tissue can be tested for genetic defects.
Chorionic villi & Decidua Basalis
The three types of villi are: Intestinal villi-microscopic finger like projections on the inner surface of the ileum. Chorionic villi-villi on the outermost membrane of the foetus. Arachnoid villi-villi on the arachnoid membrane of the brain.
The endometrium begins to form shortly after the fertilized egg (blastocyst) implants into the uterine wall (endometrium). This typically occurs 3-4 days after fertilization. After implantation, the endometrium is called the Decidua, and basalis is the portion directly under the blastocyst. The Basalis joins the chorionic villi to make the placenta. APEX~ a few days after fertilization
Chorionic villus sampling involves the removal of a small amount of tissue directly from the chorionic villi (minute vascular projections of the fetal chorion that combine with maternal uterine tissue to form the placenta).
