## Abstract

The bioinjection device has a housing including a pistol grip and an elongated barrel. 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 having a unitary structure containing a medicament disposed about the opening at the distal end of the elongated barrel, the tip removably attachable to the distal end of the elongated barrel, the medicament being disposed in the most distal portion of the tip before use of the bioinjection device, the tip including an aperture for dispensing the medicament; and
a spring-biased actuator coupling the trigger with the inner shaft, the spring-biased actuator forcing the medicament contained in the tip through the aperture 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, wherein the tip includes a plurality of apertures for dispensing medicament.

### Claim 3 (depends on 2)

The bioinjection device of claim 2, further comprising a directional control member associated with the plurality of apertures that is operative to selectively control the amount of dispersion of medicament from each of the plurality of apertures.

### Claim 4 (depends on 3)

The bioinjection device of claim 3, wherein the directional control member is rotatable to close at least one aperture out of the plurality of apertures while leaving at least another one aperture out of the plurality of apertures in an open position for dispensing the medicament.

### Claim 5 (depends on 3)

The bioinjection device of claim 3, wherein the directional control member is used to control the location or angle of dispersion of the medicament.

### Claim 6 (depends on 2)

The bioinjection device of claim 2, wherein the plurality of apertures are located along the tip equal-distant about the circumference of the tip.

### Claim 7 (depends on 1)

The bioinjection device of claim 1, wherein the aperture has a diameter between 10 millimeters and 17 millimeters.

### Claim 8 (depends on 1)

The bioinjection device of claim 1, wherein the aperture is 5 millimeters in length.

### Claim 9 (depends on 1)

The bioinjection device of claim 1, wherein the medicament can be prepared to a desired specification during a procedure.

### Claim 10 (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.
