Publication number: 20040236343Abstract: An insertion tool containing an elastomeric band, ejection pin and cartridge assembly for holding a transcornea shunt during insertion procedures. The proximal flange of the shunt is gently held in a visible position within an adjustable opening in the elastomeric band at the distal end of the ejection pin. A slide mechanism is provided along the exterior surface of the insertion tool to drive the cartridge assembly which applies tension to the elastomeric band, increasing the opening diameter securing the shunt and allowing gentle release of the shunt when desired. Alternative embodiments of the insertion tool utilize severable fibers, a transparent split-mylar sheet or diaphragm, a cantilever fork, a collet assembly or an elastomeric grip collet to gently hold and release the shunt during insertion.Type: ApplicationFiled: May 23, 2003Publication date: November 25, 2004Inventors: Jon B. Taylor, Edwin G. Lee, Margaret B. Mulhern, Timothy J. Morrill, Dana M. Cote

Patent number: 6371966Abstract: A corneal incision device of the present invention includes a surgical blade and a frame having an inner surface with a configuration that is generally in the shape of a ring-like segment of a hollow sphere. The frame has an aperture therein to allow the surgical blade to be inserted through the frame beyond the inner surface. The aperture is sized and shaped to allow movement of the surgical blade in one axis. The device may have a protuberance affixed to the inner surface of the frame adjacent to the aperture disposed to distort a surface of a patient's eye when the device is selectively positioned on the eye by a practitioner. The device has provisions for holding, advancing and withdrawing the surgical blade through the aperture, disposed on the frame. The device is releasably retained on the patient's eye by fixation elements disposed on the inner surface of the frame. There is a handle affixed to the frame to facilitate the practitioner's manipulation of device.Type: GrantFiled: February 10, 2000Date of Patent: April 16, 2002Assignee: Becton, Dickinson and CompanyInventors: Robert W. Pierce, Joseph F. Keenan, Dana Michael Cote, Edwin G. Lee

Patent number: 6306155Abstract: A capsulorhexis forceps is described which includes a unique removable hub and handle. The hub allows the use of the forceps as a cystotome in addition to a forceps. The hub design comprises a coaxial wire inside a cannula which provides minimal trauma when the forceps is opened and closed for repositioning during the capsulotromy. The hub is also replaceable and disposable after use. This flexibility in hub replacement allows the surgeon to use the forceps either in the initial open or closed position. The handle also may provide a constant grip force to the corneal flap independent of manual actuation force of the forceps.Type: GrantFiled: October 25, 1999Date of Patent: October 23, 2001Assignee: Becton, Dickinson and CompanyInventors: Lamar Chandler, Edwin G. Lee, Thomas Mc Linden, Aaron Szymanski

Patent number: 6171324Abstract: A corneal marker and a method of using a corneal marker are disclosed. The corneal marker includes a handle having a head coupled thereto. The inferior surface of the head includes a set of protuberances which form marking surfaces adapted to simultaneously engage corneal tissue. The marking surfaces form opposing sets of marks which allow a surgeon to form an incision of precise length and width. An alignment line on the superior and/or front surface of the marker facilitates the positioning thereof. A method of performing clear corneal surgery following the application of markings to the cornea is also provided.Type: GrantFiled: September 30, 1998Date of Patent: January 9, 2001Assignee: Becton, Dickinson and CompanyInventors: Dana Michael Cote, Joseph Francis Keenan, Michael Joseph Murphy, Edwin G.

Patent number: 5972011Abstract: The multi-plane corneal incision form of this invention includes a frame member in the shape of a segment of a hollow sphere that fits over a patient's cornea. The inner surface of the frame member includes a protuberance that distorts the cornea when the frame member is placed against the patient's cornea. The frame member also includes an aperture adjacent to the protuberance to allow a surgical blade to pass therethrough. By carefully configuring the protuberance and aligning the aperture, a physician can insert a surgical blade into the aperture and through the distorted cornea in a planar fashion that results in a multi-plane incision in the cornea once the frame member is removed from contact with the patient's cornea.Type: GrantFiled: October 23, 1998Date of Patent: October 26, 1999Assignee: Becton Dickinson and CompanyInventors: Robert W. Pierce, Edwin G. Lee, Dana M. Cote

Patent number: 5924206Abstract: The reusable device handle of this invention includes a nosepiece, a body, an activation rod, an ejector rod and a biasing mechanism. The nosepiece and the body are generally hollow. The nosepiece is connected to the body. The activation rod and the ejector rod are connected together and are disposed in the nosepiece and the body. The biasing mechanism is disposed in the body and biases the activation rod toward the proximal end of the body so that the proximal portion of the activation rod extends proximally from the proximal end of the body. The distal end of the nosepiece is designed to accept a cartridge therein that holds a blade or some other tool. The cartridge can be removably connected to the nosepiece. By pressing the proximal end of the activation rod, the distal end of the ejector rod contacts the cartridge and ejects the cartridge from the nosepiece.Type: GrantFiled: September 30, 1997Date of Patent: July 20, 1999Assignee: Becton, Dickinson and CompanyInventors: Dana M. Cote, Edwin G. Lee, Robert W. Pierce
