    摘要： An orthopedic implant comprising a deformable, expandable implant body configured for treating abnormalities in bones, such as compression fractures of vertebra, necrosis of femurs and the like. An exemplary implant body comprises a small cross-section threaded element that is introduced into a bone region and thereafter is expanded into a larger cross-section, monolithic assembly to provide a bone support. In one embodiment, the implant body is at least partly fabricated of a magnesium alloy that is biodegradable to allow for later tissue ingrowth.

    摘要： Systems and methods for delivering bone cement into a bone can include a handle body defining a flow path, a thermal emitter in the handle body to apply energy to bone cement passing through the flow path, a source of bone cement and an injection cannula. The cannula can be in communication with the flow path such that inserting the cannula into a bone can allow a flow of bone cement therethrough to an opening at a distal end of the cannula. Other systems and methods for delivering bone cement into a bone can include an injector body with a handle portion, and a cannula, a bone cement container, a low pressure drive mechanism configured to effect a flow of bone cement from said container to the injector body and a high pressure drive mechanism configured to effect a flow of bone cement through the injector body into the bone.

    摘要： The present invention relates in certain embodiments to systems and methods for use in osteoplasty procedures, such as vertebral compression fractures. One system for injecting a bone fill material includes a container carrying a bone fill material. An elongated introducer configured for introduction into a vertebral body is coupleable to the container to allow a flow of the bone fill material therethrough. A cooling mechanism is coupled to the container and is configured to cool the bone fill material in the container to extend the working time of the bone fill material. One method for treating a vertebra includes providing a bone fill material, cooling the bone fill material to stall the polymerization of the bone fill material, heating the bone fill material to accelerate the polymerization of the bone fill material and delivering the bone fill material into a vertebral body.

    摘要： A medical instrument coupled to first and second energy means and a computer controller for the controlled volumetric removal of thin tissue layers. The system provides a source for introducing a gas to controllably form and capture transient gas volumes in a microchannel structure at the working surface of the instrument that interfaces with a targeted tissue site. Each of the microchannel features of the working surface carries an electrode element coupled to the electrical source. The energy may be applied to the targeted site in either of two modes of operation, depending in part on voltage and repetition rate of energy delivery. In one mode of energy application, electrical potential is selected to cause an intense electrical arc across the transient ionized gas volumes to cause an energy-tissue interaction characterized by tissue vaporization. In another preferred mode of energy delivery, the system applies selected levels of energy to the targeted site by means of an energetic plasma at the instrument working surface to cause molecular volatilization of surface macromolecules thus resulting in material removal. Both modes of operation limit collateral thermal damage to tissue volumes adjacent to the targeted site. Another preferred embodiment provides and an ultrasound source or other vibrational source coupled to the working end to cause cavitation in fluid about the working end.

    摘要： An electrosurgical working end for automatic modulation of active Rf density in a targeted tissue volume. The working end of the probe of the present invention defines a tissue-engagement surface of an elastomeric material with conductive elements that extend therethrough. In one embodiment, the expansion of the elastomeric material can de-couple the conductive elements from an interior electrode based temperature to modulate current flow. In another embodiment, the elastomeric material can couple and de-couple the conductive elements from an interior electrode based engagement pressure to modulate current flow.

    摘要： A vaso-occlusive system comprising a catheter with a working end that carries a fluid media for introduction into an aneurysm. The fluid media carries a volume of microspheres, wherein each microsphere has a sacrificial shell or coating that surrounds an interior core portion of the microsphere. The core portions of the microspheres comprise either a first or second polymerizing composition, wherein interaction of such binary compositions will cause polymerization of the media into a gel or solid media that will occlude the aneurysm. An energy delivery means is provided within the catheter working end to cause removal of the sacrificial coatings of the volume of microspheres to thereby induce the polymerization process.

    摘要： A surgical system for controlled application of ultrasound energy to engaged tissue volumes for creating effective biological welds or seals in tissue. The invention provides an ultrasound transmission assembly including piezoelectric elements coupled to an elongate waveguide that is reciprocatable in an interior of an introducer. The reciprocatable waveguide assembly of the invention is adapted to have multiple functionality: (i) to couple ultrasound energy to both opposing jaws to thereby deliver energy to both sides of engaged tissues to create uniform thermal weld effects; (ii) to apply very high compressive forces to captured tissues over the length of elongate jaws by engaging substantially the entire length of the jaws, and (iii) to transect the captured tissues contemporaneous with the delivery of energy to create the thermal weld. The invention further provides for use of other energy sources to deliver thermal energy to tissue, for example microwave energy, Rf energy and laser energy, either in combination with ultrasound energy or independently.
