Embodiment

[0195]As an illustrative example, the polyetherimides used to form the devices of the present disclosure can exhibit different properties as shown in Tables 2 and 3 than other control polymers, as shown in Tables 2-3 ( PEI-polyetherimide; PPSU-polyphenylsulfone; PSU-polysulfone; PEEK-polyether ether ketone; TPU-thermoplastic polyurethane).

[0196] The following data apply: Tensile stress in millimeters per minute (mm / min), kilogram-force-centimeter (cm-kgf / cm), kilogram-force per square centimeter (kgf / cm 2 ) to obtain. Heat deflection temperature (HDT) is measured in megapascals (MPa). Volume resistivity is measured in ohm-centimeters (Ohm·cm).

Abstract

Devices prepared from resins are disclosed. In one aspect, a spinal cage is disclosed for implantation between two adjacent vertebrae, the spinal cage formed from a polymer composition comprising a polyetherimide, polyether ether ketone or other biocompatible resin, the spinal cage formed from a process comprising: receiving an input relating to design specifications of the spinal cage; and causing formation of at least a portion of the spinal cage based upon the input and using one or more of an additive and subtractive process.

Description

technical field [0001] The present disclosure relates generally to implantable medical devices and surgical instruments having improved properties, and more particularly to spinal fusion systems and methods of manufacture thereof, the spinal fusion systems comprising a spinal frame having improved mechanical strength and Biocompatibility while promoting fusion between vertebrae. Background technique [0002] Disc degeneration is an increasingly common problem that many people suffer from. Typically, the spinal problem is resolved by removing the damaged or defective disc material and replacing it with a spinal implant that fuses two adjacent vertebrae. [0003] Spinal fusion techniques, such as intervertebral fusion, involve the placement of bone grafts between vertebrae in the area occupied by intervertebral discs. The damaged disc is completely removed in preparation for spinal fusion. A spinal brace is then placed between the vertebrae to maintain spinal alignment and ...
