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.

Abstract: A needle guidance attachment device for an endoluminal ultrasound probe that allows removal of the probe while the needle is in position in the tissue. The device includes an elongated needle carrier having a longitudinal slot with a transverse opening. The carrier includes a pair of retaining bands adapted to fit around a cylindrical-shaped ultrasound transducer and to orient the needle carrier along the longitudinal axis of the probe. An elongated cover is slidably coupled to the carrier in a longitudinal orientation such that at least a portion of the slot is covered in a first, closed position and uncovered in a second, opened position. The cover moves between its open and closed position axially about the longitudinal axis of the needle carrier.
