Abstract
Abstract A temporary implant for tendon surgery which comprises a generally cylindrical tube of a continuous filamentary material, said cylindrical tube having openings on the surface thereof defined by said filamentary material; a generally flat planar member composed of a resilient yieldable filamentary material, which member can be used as a temporary implant in tendon surgery; a generally cylindrical tube in the form of a continuous filamentary material, which material runs in an undulating, sinuous path, the apex and the nadir of the path of the filamentary material being brought toward one another in a generally facing relationship to define a substantially enclosed area having spaces between the filamentary material; a transplant comprising a substantially enclosed generally cylindrical object constructed of a filamentary material, which filamentary material runs continuously in an arcuate path from a point of said cylindrical object to a point substantially 360* away on the surface of said object, at which point it reverses its direction and travels in an arcuate path substantially 360* away on the surface of said object, at which point it reverses itself; an improvement in surgically repairing broken tendons which comprises disposing about the junction of the repaired tendon a temporary implant comprising a generally cylindrical tube of a continuous filamentary material, said cylindrical tube having openings on the surface thereof defined by said filamentary material, and after the junction in the tendon has substantially healed, removing said cylindrical tube by pulling an end of said filamentary material to thereby sever adhesions formed between the tendon and neighboring tissue material; in a process for the surgical correction of at least one severed tendon where the tendon is disposed close to but out of contact relationship to a second tendon, the improvement for surgically repairing said tendon which comprises disposing between the severed tendon and the adjoining tendon a generally flat planar member composed of yieldable filamentary material, allowing the junction of the severed tendon to heal, and, thereafter, removing said generally flat planar member by pulling an end of said filamentary material.
