  • Publication number: 20080064984
    Abstract: An apparatus for removing tissue and/or other material from a patient, particularly a breast of a patient, is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to draw soft tissue into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration.

  • Publication number: 20080035158
    Abstract: Apparatus and methods are provided for treating sleep apnea, snoring, and the like using an implant within an oropharyngeal region adjacent an anterior longitudinal ligament. The implant includes an endless loop defining a curved central region between first and second regions in a horizontal plane. The central region is vertically narrow relative to the first and second regions, and the first and second regions are compressible vertically to allow the first region to be directed through or behind the ligament adjacent the oropharyngeal region such that the central region is disposed within or behind the ligament. The first region is resiliently expandable after passing through or behind the ligament to contact tissue adjacent the oropharyngeal region. The first and second regions are compressible into a ā€œCā€ shape within the horizontal plane, yet biased to expand and apply a force to dilate the tissue adjacent the oropharyngeal region.

  • Publication number: 20070255172
    Abstract: An apparatus and method for removing intervertebral disc material, particularly nucleus pulposus, from a patient is provided. The apparatus generally includes a handpiece and a tissue removal mechanism connected thereto. The tissue removal mechanism includes a cannula adapted to be inserted into an intervertebral disc and having an open distal tip and an outer diameter of less than about 5 mm, or less than about 2 mm. The mechanism further includes a rotatable element having a distal portion with helical threading. The distal portion of the rotatable element extends beyond the open distal tip of the cannula in order to allow tissue to prolapse between turns of the helical threading. The apparatus is designed to aspirate nucleus pulposus into the cannula upon rotation of the rotatable element and without the need for supplemental sources of aspiration. The invention further provides a method for monitoring intervertebral disc pressure before, during and/or after a treatment procedure.

  • Publication number: 20070197853
    Abstract: Spinal disc therapy systems in accordance with the present invention generally include an implant element structured to have a therapeutic effect on a human or animal body when implanted into an intervertebral disc annulus or intervertebral disc nucleus. The implant element may include a biochemically active agent that provides pain relief, inflammation relief or other benefit to the human or animal body. The implant element may be mechanically active or mechanically activatable in being effective in providing a therapeutic effect to the human or animal body when implanted in the intervertebral disc. For example, the implant element may include a mechanically active or mechanically activatable component that radiates wave energy, for example, in the form of electrical or magnetic energy, into the body.

  • Publication number: 20050199248
    Abstract: An apparatus and method for treating sleep apnea and/or snoring is provided. The apparatus includes an appliance sized and structured to be placed in the pharyngeal region of a human or animal and being effective in treating sleep apnea and/or snoring, for example in maintaining openness of an oropharyngeal region of a human or animal during natural sleep, advantageously while not interfering with normal functioning of the epiglottis. Preferably, the appliance is non-circumferential in form and includes rounded, spaced apart end portions.
