A trigger is pivotally mounted to the housing. An inner shaft having a distal end is slidable between a first position in which the distal end of the inner shaft is disposed in the barrel and a second position in which the distal end of the inner shaft extends past an opening in the end of the barrel. A tip containing a medicament is disposed about the opening of the elongated barrel. The tip includes at least one aperture for dispensing the medicament. One can inject the medicament from the tip into a bone fracture or degenerative bone tissue during surgery by actuating the trigger of the bioinjection device. A configurable tip may be employed to control the amount and direction of dispersion of such medicament. ## Claims ### Claim 1 A bioinjection device, comprising: a housing having a handle member and an elongated barrel connected to the handle member, the elongated barrel having a channel and a distal end defining an opening; a trigger pivotally mounted on the housing; an inner shaft having an end portion, the inner shaft is received within the elongated barrel, the inner shaft being slidable along the channel of the elongated barrel between a first position in which the end portion of the inner shaft is retracted within the elongated barrel and a second position in which the end portion of the inner shaft extends past the opening at the distal end of the elongated barrel; a tip positioned at the most distal end of the bioinjection device, the entire tip removably attachable to the distal end of the elongated barrel, the tip containing a medicament, the medicament being disposed in the most distal portion of the tip before use of the bioinjection device, and the tip including a plurality of apertures for dispensing the medicament; and a spring-loaded actuation mechanism coupling the trigger with the inner shaft to force the medicament contained in the tip through the plurality of apertures of the tip into a body tissue positioned adjacent to the tip when the trigger is actuated. ### Claim 2 (depends on 1) The bioinjection device of claim 1, further comprising a directional control member that is operative to selectively control the amount of dispersion of medicament from each of the plurality of apertures. ### Claim 3 (depends on 2) The bioinjection device of claim 2, wherein the directional control member is rotatable to close at least one aperture of the plurality of apertures while leaving at least another one aperture of the plurality of apertures in an open position for dispensing the medicament. ### Claim 4 (depends on 2) The bioinjection device of claim 2, wherein the directional control member is used to control the location or angle of dispersion of the medicament. ### Claim 5 (depends on 1) The bioinjection device of claim 1, wherein the plurality of apertures are located along the tip equal-distant about the circumference of the tip. ### Claim 6 (depends on 1) The bioinjection device of claim 1, wherein the plurality of apertures has a diameter between 10 millimeters and 17 millimeters. ### Claim 7 (depends on 1) The bioinjection device of claim 1, wherein the plurality of apertures is 5 millimeters in length. ### Claim 8 (depends on 1) The bioinjection device of claim 1, wherein the medicament can be prepared to a desired specification during a procedure. ### Claim 9 (depends on 1) The bioinjection device of claim 1, wherein the medicament is comprised of one or more from the group comprising autograft, allograft and BMP. ### Claim 10 A bioinjection device, comprising: a housing having a handle member and an elongated barrel connected to the handle member, the elongated barrel having a channel and a distal front end defining an opening; a trigger pivotally mounted on the housing; an inner shaft having an end portion received within the channel of the elongated barrel, the inner shaft being slidable between a first position in which the end portion of the inner shaft is retracted within the elongated barrel and a second position in which the end portion of the inner shaft extends past the opening at the distal front end of the elongated barrel; a tip positioned at the most distal end of the bioinjection device, the entire tip removably attachable to the distal front end of the elongated barrel, the tip containing a medicament, the medicament being disposed in the most distal portion of the tip before use of the bioinjection device, and the tip having a plurality of apertures for enabling dispensing of the medicament there-through and into a body tissue positioned adjacent to the tip when the inner shaft is in the second position; and the plurality of apertures each having an initial sealed state so that one of more of the plurality of apertures can subsequently be opened by a user of the bioinjection device to control the direction of dispersion of the medicament through the one or more of the plurality of apertures. ### Claim 11 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures have a diameter between 10 millimeters and 17 millimeters. ### Claim 12 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures are 5 millimeters in length. ### Claim 13 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures are located along the tip equal-distant about the circumference of the tip. ### Claim 14 (depends on 10) The bioinjection device of claim 10, wherein each of the plurality of apertures are sealed using one or more materials in the group comprising foil, plastic, silicon, polymers, acrylics, and metal strips. ### Claim 15 (depends on 10) The bioinjection device of claim 10, wherein each of the plurality of apertures may be selectively opened, perforated, or removed to control the direction or angle of medicament dispersion. ### Claim 16 (depends on 10) The bioinjection device of claim 10, wherein the medicament includes of one or more from the group comprising autograft, allograft and BMP. ### Claim 17 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures vary in size, one from the other. ### Claim 18 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures vary in shape, one from the other. ### Claim 19 (depends on 10) The bioinjection device of claim 10, wherein the plurality of apertures are all of the same shape.
