1. An apparatus for performing genetic transformation of a living organism in vivo by accelerating carrier particles coated onto a carrier sheet into the organism comprisinga manually manipulable handle;
- a body member mounted on the handle and of a size and shape so as to be readily carried and manually handled;
a carrier sheet;
the body member having an interior and a spark discharge chamber formed in the interior, the spark discharge chamber including a carrier sheet mounting location for mounting the carrier sheet thereon, the spark discharge chamber constructed so to present a shock wave to the carrier sheet mounting location;
a pair of electrodes extending into the body member and into the discharge chamber;
a carrier sheet retaining means removably attachable to the body member and located over the carrier sheet mounting location;
said carrier sheet retaining means includinga retaining screen located spaced from the carrier sheet so that the carrier sheet will impact the retaining screen when accelerated from the carrier sheet mounting location;
a support unit including a source of electrical discharge energy; and
an umbilical connecting the electrode to the support unit, so that electrical energy can be supplied to the electrodes for initiating an electric spark discharge between the electrodes while permitting the body member to be readily placed adjacent the organism to be transformed.

Abstract
An apparatus for the particle mediated genetic transformation of organisms in vivo has two parts, a support unit and a hand unit. The hand unit is of a convenient hand manipulable size so that it can be placed readily against the organism the cells of which are to be transformed. The hand unit is connected to the support unit by a flexible umbilical so that the hand unit can be placed where desired. The apparatus is particularly well adapted for the convenient transformation of somatic cells of whole animals or humans.

6. An apparatus for performing a genetic transformation of a living organism by the acceleration of carrier particles comprising:
-
a support unit constructed and arranged so as to supply a motive force for accelerating carrier particles into the organism; and hand-held means comprising a body member, a carrier sheet, and a retaining screen for retaining the carrier sheet attached to the body member, the body member having formed in it a discharge chamber constructed so as to generate a shock wave from said motive force and to direct shock wave therein toward the carrier sheet and constructed so as to hold the carrier sheet thereon in such a way that the shock wave will be applied to accelerate the carrier sheet, the retaining screen arranged so as to retain the carrier sheet after it is accelerated so that the carrier particles are separated therefrom; and umbilical means for transmitting the motive force from the support unit to the hand-held unit. - View Dependent Claims (7, 8, 9, 10)
