Means For Removing, Inserting Or Aiding In The Removal Or Insertion Of Eye Lens Material Patents (Class 606/107)
  • Patent number: 10368912
    Abstract: A fluid management system for use with a fluid reservoir includes an inflow pump and an outflow pump. The inflow pump is connectable to a probe for delivering a distention fluid to a body cavity. The outflow pump removes the distention fluid through the same probe, thus establishing a re-circulating volume of distention fluid within the body cavity. The removed fluid is filtered and returned to a fluid reservoir for eventual recycling to the body cavity. A controller adjusts the flow rates of the inflow pump and the outflow pump to maintain a pre-selected fluid pressure or volume within the body cavity.

  • Patent number: 10299809
    Abstract: A two phase method for reducing the formation of biofilm includes an evacuation of ambient air from a region about the surgical or treatment site, to extract airborne or aerosolized bacteria ejected from the site by the treatment. The extracted bacteria are prevented from settling back onto the cleansed tissue surface, thus at least reducing colonial bacteriological growth and concomitantly exuded biofilm material. A second phase involves the attachment of one or more ultrasonic transducers to the patient over or near a surgical treatment site after the surgery is terminated. Each applied ultrasonic transducer is used to vibrate the patient's tissues at the treatment site to disrupt biofilm formation.

  • Patent number: 9895258
    Abstract: Described here are systems and methods for accessing Schlemm's canal and for delivering an ocular device or fluid composition therein. The ocular devices may maintain the patency of Schlemm's canal without substantially interfering with transmural fluid flow across the canal. The fluid composition may be a viscoelastic fluid that is delivered into the canal to facilitate drainage of aqueous humor by disrupting the canal and surrounding trabeculocanalicular tissues. Tools for disrupting these tissues and minimally invasive methods for treating medical conditions associated with elevated intraocular pressure, including glaucoma, are also described.

  • Patent number: 9861470
    Abstract: An IOL inserter for delivering an intraocular lens (IOL) into the eye of a subject, has a handpiece with a generally tubular barrel, a nosepiece coupled to the distal end of the handpiece; and a plunger having a spiral groove. The plunger translates longitudinally within the barrel and passes through a piston with an O-ring that frictionally engages an inner surface of the barrel. The spiral groove interacts with a pin or tooth in the bore of the piston. The plunger may have a drive cap and a cover fixed on the proximal end of the drive cap. The distal end of the plunger may engage having an enlarged head that receives the distal end of the plunger. The distal end of the pushrod may have a bifurcated tip capable of contacting and urging an IOL from the inserter during the implant procedure.
