Abstract: Microspheres to be implanted into a patient are metered and mixed with fluids, cells, or tissues withdrawn from the patient's own body, and reinserted into the patient's body to achieve augmentation, repair or other treatment of the patient's tissue.

Abstract: An injection apparatus including a first body portion with a first stopper and a second body portion with a second stopper is disclosed. The first body portion is capable of receiving a first material in a portion of the first body portion distal to the first stopper. The second body portion is fluidly coupled to the first body portion, and is capable of receiving the first material in a portion of the second body portion disposed proximally of the second stopper. The second body portion is also capable of receiving a second material in a portion of the second body portion disposed distally of the second stopper.

Abstract: An elongated syringe for administering a substance to a patient includes an elongated syringe chamber that may be inserted into a duct of a patient without unwantingly injuring the patient, a needle extending from the distal end of the syringe chamber, and a plunger rod extending from the proximal end of the syringe chamber. The syringe chamber may be flexible to accommodate curvatures of the duct of the patient. The syringe chamber includes a plurality of chamber compartments that will contain a fluid. At least one of the chamber compartments contains a fluid that is administered to a patient. The syringe chamber may include a driving piston located between two or more chamber compartments. The needle of the syringe may be a component of a transition-bore needle apparatus to facilitate delivery of a relatively viscous fluid from the syringe. The needle may also be flared at its proximal end so that the diameter of the proximal end of the needle is greater than the diameter of the distal end of the needle.

Abstract: An injection apparatus includes components that facilitate injection of relatively viscous materials into a patient. An injection apparatus may include a transition-bore needle apparatus, which has a proximal end, a distal end, and a lumen extending from the proximal end to the distal end, in which the diameter of the proximal end is greater than the diameter of the distal end. An injection apparatus may include a hand-held injection facilitation apparatus, which may be coupled to a syringe. The hand-held injection facilitation apparatus can include a pivot arm and a body with a rod disposed within the body and coupled to the pivot arm. Movement of the pivot arm results in a proximal or distal movement of the rod within the body to effectively cause material to be expelled from the syringe. An injection apparatus may include a transition-bore needle apparatus and a hand-held injection facilitation apparatus in combination.

Abstract: A surgical device for expanding and viewing tissue is disclosed. The surgical device includes a handle, an insertion probe, and at least one window disposed within the insertion probe. The handle has a proximal end and a distal end, and the handle is sized and shaped to be held by a surgeon. The insertion probe has a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end. The proximal end of the insertion probe is removably attached to the distal end of the handle. The window extends along a length of the longitudinal axis, and has an opening that is sufficient in size to allow tissue to prolapse through the window and into the insertion probe.
