ABSTRACT:
A needle biopsy guide system is disclosed for attachment to an endoluminal ultrasound probe or like sonographic instrument. The device includes a biopsy-guide attachment that allows for trocar catheter placement for abscess drainage or like procedures, using the transvaginal or transrectal route under sonographic control. The device has a base portion, which is attachable to an ultrasound probe. A removable retainer is provided that slides into the base unit to hold a biopsy needle in place. A physician may locate the target area in the body with the ultrasound probe, insert the biopsy needle into the target area, and then remove the insert (retainer) from the base unit and ultrasound probe, and leave the biopsy needle in place in the body.
