Abstract
A needle biopsy system for marking a sampling site is described.
Claims34
A needle biopsy system, comprising:
- a sampling portion locatable inside the body and including a stylet having a sampling region and a cannula, the stylet and cannula relatively moveable along the stylet axis to position the cannula over the sampling region, and
- a sample marker locatable in and releasable from the sampling portion.
A method of biopsy treatment, comprising:
- providing a needle biopsy device including a sampling portion with a stylet having a sampling region and a cannula, the stylet and the cannula relatively moveable to position the stylet over the sampling region,
- inserting the stylet into a tissue mass,
- causing relative motion between the stylet and the cannula to locate the cannula over the sampling region, and
- while removing the stylet from the tissue, delivering a marker from the sampling portion into the tissue.

A method of biopsy treatment, comprising:
- taking multiple biopsy samples from a tissue,
- marking the location of each of said multiple samples by contemporaneously with the taking of each sample, releasing a marker in the tissue mass, the marker being detectable by ultrasound, x-ray, or magnetic resonance imaging,
- analyzing the tissue samples, and
- treating tissue corresponding to the location of at least one of the samples.
