Inventors:

Cary Hagan - Germantown TN, US
Harris Brian - Cordova TN, US

International Classification:

A61F005/00

US Classification:

606086000

Abstract:

Methods for treating osteolytic bone lesions of all kinds are disclosed. The method includes making two holes in the bone adjacent the lesion and first applying a negative pressure source to one hole and then injecting a flushing fluid into the other. The method also includes replacing the flushing fluid line with a source of, at least, bioimplantable material to fill the void left by the flushed out bone lesion.

US Classification:

623 1314, 128898, 606151, 606228

Abstract:

Methods for tendon and ligament repair using a scaffolding matrix material. The scaffolding matrix material is an off-the-shelf organic dermis from an unknown source which has been extra-operatively prepared so as to be devoid of viable cells which normally express antigens, and to promote natural healing of soft tissue via revascularization and repopulation. The scaffolding matrix material is used to join ruptured tendons or ligaments together and to join ligaments to bone.
