Abstract
Systems for treating and/or preventing fractures include at least one needle sized and configured to be placed into target bone and at least one implantable pin configured to be releasably held in a first needle of the at least one needle. The systems also include at least one delivery device of injectable material configured to couple to the first needle while the first implantable pin is held in the first needle whereby the at least one delivery device and a respective needle cooperate to serially provide an external column of the injectable material about the at least one implantable pin.
Claims41
A medical implant system for structurally augmenting bone or treating a fracture, comprising:
- at least one needle sized and configured to be placed into target bone;
- at least one implantable pin, a first implantable pin of the at least one implantable pin configured to be releasably held in a first needle of the at least one needle;
- and
- at least one delivery device of injectable material configured to couple to the first needle while the first implantable pin is held in the first needle whereby the at least one delivery device and the first needle cooperate to provide an external column of the injectable material about the first implantable pin.
An implantable medical truss system for target bone, comprising:
- a plurality of spaced apart implantable pins adapted to reside in the target bone, wherein, in position, the implantable pins are configured to have different and intersecting trajectories, wherein the implantable pins comprise a cross-sectional shape having an outer perimeter defined by a plurality of valleys and projections, and wherein, in position, at least some of the implantable pins are configured to have segments that couple to each other and/or that overlap with each other in different planes.
A method of treating a fracture and/or structurally reinforcing target bone, comprising:
- placing a needle in target bone;
- inserting an implantable pin into the needle prior to, during, or after the needle is placed in the target bone;
- flowably delivering a biocompatible and/or non-cytotoxic material into the needle and about the implantable pin while the implantable pin is held in the needle to provide an external column of the injectable material about the implantable pin;
- and
- withdrawing the needle from the target bone during the flowable delivery while leaving the implantable pin in position in the bone channel thereby implanting the implantable pin in the target bone with the external column of biocompatible and/or non-cytotoxic material coupled to the implantable pin and adjacent bone.
