20080215078 | SURGICAL BLADE AND TROCAR SYSTEM - The present invention provides an improved surgical blade and trocar system for accessing the retina and other parts of the eye while doing vitreo-retinal and cataract surgeries, including surgeries for macular degeneration. The eye surgeon uses an improved surgical blade for vitreo-retinal and cataract surgeries having a generally flat, V-shaped, W-shaped, or “extended W” shaped cross-section. Using the improved surgical blade, the surgeon creates a multi-planar, self-sealing surgical wound, first by directing the surgical blade substantially perpendicular to the eye surface, then redirecting the blade to follow the general curvature of the eye globe, and finally redirecting the blade to enter the interior of the eye. The improved surgical blade is used with an improved trocar system having two main parts-a relatively rigid, wide-mouthed outer segment and a generally thin-walled, collapsible plastic polymer or metal mesh sleeve that spans the surgical wound and substantially molds to its contour. The improved surgical blade and trocar system can be adapted for use in either vitreo-retinal or cataract surgeries. | 09-04-2008 |

The system includes a control unit that can determine a position of the distal end of the cutting implement relative to a reference surface based on input from the optical coherence tomography system. The control unit can control the cutting implement to compensate for relative motion between the tool body and the reference surface, and can maintain a predetermined depth of the distal end of the cutting implement with respect to the reference surface. | 10-22-2015 |
20150313627 | CATHETER HAVING TAPERED GUIDE SURFACE - A catheter assembly includes a catheter body having a catheter lumen. A manifold assembly is coupled with a proximal catheter portion. A manifold lumen extends through the manifold assembly, and the manifold lumen includes an assembly cavity extending around the proximal catheter portion. A fluid jet loop is coupled with a high pressure tube at a distal catheter portion. The catheter assembly further includes a tapered loop guide surface. | 11-05-2015 |
20150366714 | ELECTRONIC EYE MARKING DEVICE - An electronic eye marking device for marking reference points on a patient's eye in preparation for refractory eye surgery. The device senses its spatial orientation and compares it to the desired target spatial orientation necessary to the patient's eye. The device provides audible and/or visual signals to the user indicating whether the eye marking device is positioned within a predetermined range of the desired target spatial orientation, and it alters the audible and/or visual signals in response to changes in the sensed spatial orientation of the device, thereby providing the user indication of movement closer to, or further from, the desired target spatial orientation. | 12-24-2015 |
20160022489 | EYE SURGICAL CUTTING TOOL - An eye surgical cutting tool includes a tubular outer part and an axially movable tubular inner part arranged in the outer part. The outer part has a closed distal end, and the inner part has an open distal end. Both parts have an opening in the tube. Both openings are bounded on the distal side by a distal cutting edge in the respective tube. The axial position of the distal cutting edge of the inner part as a function of the circumferential direction initially proceeds towards the proximal end, and then back to the distal end again. The tool is provided with suction means to have, during use of the cutting tool, ocular tissue extended through the opening of the outer part into the interior of the outer part and to convey severed tissue via the interior of the inner part to a proximal end of the inner part. | 01-28-2016 |
20160067096 | TREPHINE GUIDE - There is disclosed a trephine guide having an upper guide member having a first substantially circular guide aperture and a first circumferential portion and a lower guide member having a second substantially circular guide aperture and a second circumferential portion. The upper and lower guide members are connected in a spaced apart configuration by at least one arm extending from the first circumferential portion to the second circumferential portion, such that the first and second guide apertures are substantially concentric, thereby to allow a trephine to pass through the upper and lower guide members. The at least one arm has a width that extends over less than three quarters of the circumference of the first or second circumferential portions to allow good visibility to a trephine blade. | 03-10-2016 |
20160120570 | MEDICAL DEVICE AND TREATMENT METHOD - A treatment method and medical device are disclosed for cutting a substance inside a body lumen. The medical device includes a drive shaft that is rotatable; a strut that is rotatably connected to a distal side of the drive shaft, that extends along a rotation axis, and whose central portion is expandable radially outward; and a support portion that is rotatably connected to the distal side of the drive shaft, that is formed in a mesh shape and a tubular shape while including multiple gaps, at least a portion of which is positioned on a radially inner side of the strut, and that is expandable radially outward by a central portion in a direction extending along the rotation axis being bent. | 05-05-2016 |
