Medical devices and applications of polyhydroxyalkanoate polymers

Devices formed of or including biocompatible polyhydroxyalkanoates are provided with controlled degradation rates, preferably less than one year under physiological conditions. Preferred devices include sutures, suture fasteners, meniscus repair devices, rivets, tacks, staples, screws (including interference screws), bone plates and bone plating systems, surgical mesh, repair patches, slings, cardiovascular patches, orthopedic pins (including bone filling augmentation material), adhesion barriers, stents, guided tissue repair/regeneration devices, articular cartilage repair devices, nerve guides, tendon repair devices, atrial septal defect repair devices, pericardial patches, bulking and filling agents, vein valves, bone marrow scaffolds, meniscus regeneration devices, ligament and tendon grafts, ocular cell implants, spinal fusion cages, skin substitutes, dural substitutes, bone graft substitutes, bone dowels, wound dressings, and hemostats. The polyhydroxyalkanoates can contain additives, be formed of mixtures of monomers or include pendant groups or modifications in their backbones, or can be chemically modified, all to alter the degradation rates. The polyhydroxyalkanoate compositions also provide favorable mechanical properties, biocompatibility, and degradation times within desirable time frames under physiological conditions.

High frequency thermal ablation of cancerous tumors and functional targets with image data assistance

This invention relates to the destruction of pathological volumes or target structures such as cancerous tumors or aberrant functional target tissue volumes by direct thermal destruction. In the case of a tumor, the destruction is implemented in one embodiment of the invention by percutaneous insertion of one or more radiofrequency probes into the tumor and raising the temperature of the tumor volume by connection of these probes to a radiofrequency generator outside of the body so that the isotherm of tissue destruction enshrouds the tumor. The ablation isotherm may be predetermined and graded by proper choice of electrode geometry and radiofrequency (rf) power applied to the electrode with or without temperature monitoring of the ablation process. Preplanning of the rf electrode insertion can be done by imaging of the tumor by various imaging modalities and selecting the appropriate electrode tip size and temperature to satisfactorily destroy the tumor volume. Computation of the correct three-dimensional position of the electrode may be done as part of the method, and the planning and control of the process may be done using graphic displays of the imaging data and the rf ablation parameters. Specific electrode geometries with adjustable tip lengths are included in the invention to optimize the electrodes to the predetermined image tumor size.

Generation of a computerized bone model representative of a pre-degenerated state and useable in the design and manufacture of arthroplasty devices

Disclosed herein is a method of generating a computerized bone model representative of at least a portion of a patient bone in a pre-degenerated state. The method includes: generating at least one image of the patient bone in a degenerated state; identifying a reference portion associated with a generally non-degenerated portion of the patient bone; identifying a degenerated portion associated with a generally degenerated portion of the patient bone; and using information from at least one image associated with the reference portion to modify at least one aspect associated with at least one image associated the generally degenerated portion. The method may further include employing the computerized bone model representative of the at least a portion of the patient bone in the pre-degenerated state in defining manufacturing instructions for the manufacture of a customized arthroplasty jig. Also disclosed herein is a customized arthroplasty jig manufactured according to the above-described method. The customized arthroplasty jig is configured to facilitate a prosthetic implant restoring a patient joint to a natural alignment. The prosthetic implant may be for a total joint replacement or partial joint replacement. The patient joint may be a variety of joints, including, but not limited to, a knee joint.
