  • INCORPORATION BY REFERENCE
  • [0002]
    All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.
  • FIELD OF THE INVENTION
  • [0003]
    The present invention relates generally to devices that are implanted within the eye. More particularly, the present invention relates to devices that facilitate the transfer of fluid from within one area of the eye to another area of the eye.
  • BACKGROUND OF THE INVENTION
  • [0004]
    According to a draft report by The National Eye Institute (NEI) at The United States National Institutes of Health (NIH), glaucoma is now the leading cause of irreversible blindness worldwide and the second leading cause of blindness, behind cataract, in the world. Thus, the NEI draft report concludes, “it is critical that significant emphasis and resources continue to be devoted to determining the pathophysiology and management of this disease.” Glaucoma researchers have found a strong correlation between high intraocular pressure and glaucoma. For this reason, eye care professionals routinely screen patients for glaucoma by measuring intraocular pressure using a device known as a tonometer. Many modern tonometers make this measurement by blowing a sudden puff of air against the outer surface of the eye.
  • [0005]
    The eye can be conceptualized as a ball filled with fluid. There are two types of fluid inside the eye. The cavity behind the lens is filled with a viscous fluid known as vitreous humor. The cavities in front of the lens are filled with a fluid know as aqueous humor. Whenever a person views an object, he or she is viewing that object through both the vitreous humor and the aqueous humor.
  • [0006]
    Whenever a person views an object, he or she is also viewing that object through the cornea and the lens of the eye. In order to be transparent, the cornea and the lens can include no blood vessels. Accordingly, no blood flows through the cornea and the lens to provide nutrition to these tissues and to remove wastes from these tissues. Instead, these functions are performed by the aqueous humor. A continuous flow of aqueous humor through the eye provides nutrition to portions of the eye (e.g., the cornea and the lens) that have no blood vessels. This flow of aqueous humor also removes waste from these tissues.
  • [0007]
    Aqueous humor is produced by an organ known as the ciliary body. The ciliary body includes epithelial cells that continuously secrete aqueous humor. In a healthy eye, a stream of aqueous humor flows out of the anterior chamber of the eye through the trabecular meshwork and into Schlemm's canal as new aqueous humor is secreted by the epithelial cells of the ciliary body. This excess aqueous humor enters the venous blood stream from Schlemm's canal and is carried along with the venous blood leaving the eye.
  • [0008]
    When the natural drainage mechanisms of the eye stop functioning properly, the pressure inside the eye begins to rise. Researchers have theorized prolonged exposure to high intraocular pressure causes damage to the optic nerve that transmits sensory information from the eye to the brain. This damage to the optic nerve results in loss of peripheral vision. As glaucoma progresses, more and more of the visual field is lost until the patient is completely blind.
  • [0009]
    In addition to drug treatments, a variety of surgical treatments for glaucoma have been performed. For example, shunts were implanted to direct aqueous humor from the anterior chamber to the extraocular vein (Lee and Scheppens, “Aqueous-venous shunt and intraocular pressure,” Investigative Opthalmology (February 1966)). Other early glaucoma treatment implants led from the anterior chamber to a sub-conjunctival bleb (e.g., U.S. Pat. No. 4,968,296 and U.S. Pat. No. 5,180,362). Still others were shunts leading from the anterior chamber to a point just inside Schlemm's canal (Spiegel et al., “Schlemm's canal implant: a new method to lower intraocular pressure in patients with POAG?” Ophthalmic Surgery and Lasers (June 1999); U.S. Pat. No. 6,450,984; U.S. Pat. No. 6,450,984).
  • SUMMARY OF THE INVENTION

    One aspect of the invention provides an ocular implant having a first spine; a second spine; a first strut extending in an axial direction Z between the first spine and the second spine; a second strut extending in an axial direction Z between the first spine and the second spine; wherein an angular dimension θ of a first edge of each strut undulates as the strut extends in the axial direction Z between the first spine and the second spine; and wherein a radius r of an outer surface of each strut remains substantially constant as the strut extends the axial direction Z between the first spine and the second spine.
  • [0011]
    Yet another aspect of the invention provides an ocular implant having a first spine section; a second spine section; and a first frame extending between the first spine section and the second spine section, the frame having a diameter of between 0.005 inches and 0.04 inches, the ocular implant being adapted to be disposed within a canal of Schlemm in a human eye.
  • [0012]
    In some embodiments, the first spine section, the second spine section, and the first frame form portions of a single tubular wall. Each spine section may optionally have only a single spine. In some embodiments, each spine section has an arcuate shape in lateral cross section. In some embodiments, the first spine has a first circumferential extent and the first frame has a second circumferential extent, wherein the second circumferential extent is greater than the first circumferential extent.
  • [0013]
    In some embodiments, the first frame has a first strut and a second strut and may have only two struts. Each strut may optionally have an arcuate shape in lateral cross section.
  • [0014]
    In embodiments in which the first strut has a first edge (partially defining, e.g., a first opening in the ocular implant), an angular dimension θ of the first edge may undulate as the strut extends in an axial direction Z between the first spine and the second spine. An angular dimension θ of the first edge may also first increase, then decrease, as the strut extends in an axial direction Z between the first spine and the second spine. Also, a radius r of the first edge may remain substantially constant as the strut extends in axial dimension Z between the first spine and the second spine.
  • [0015]
    In some embodiments, the first strut has a thickness that is substantially constant in a radial direction. In some embodiments, the first strut has a width extending in an arc along a circumferential direction. In some embodiments, the first strut has a length extending in an axial direction that is generally parallel to a longitudinal axis of the ocular implant.
  • [0016]
    The first spine section and the second spine section may be axially aligned with one another. A shape of the second strut may also be a mirror image of a shape of the first strut.
  • [0017]
    Some embodiments of the ocular implant have a second frame extending between the second spine and a third spine. Some embodiments of the ocular implant have a first opening extending between the first edge of the first strut and the first edge of the second strut. In some embodiments, a second edge of the first strut and a second edge of the second strut defining a second opening. In some embodiments, the first strut, the second strut, the first spine section, and the second spine section all define a cylindrical volume.
  • [0018]
    Some embodiments of the ocular implant have a therapeutic agent (e.g., an anti-glaucoma drug such as a prostaglandin analog like latanprost) deposited on the frame and spine sections.
  • [0019]
    Still another aspect of the invention provides an ocular implant having a first spine; a second spine; a first frame comprising a first strut and a second strut; each strut extending in an axial direction Z between the first spine and the second spine; a first opening of the ocular implant extending between a first edge of the first strut and a first edge of the second strut; a second edge of the first strut and a second edge of the second strut defining a second opening; wherein an angular dimension θ of the first edge of each strut undulates as the strut extends in the axial direction Z between the first spine and the second spine; and wherein a radius r of an outer surface of each strut remains substantially constant as the strut extends the axial direction Z between the first spine and the second spine.

  • [0037]
    FIG. 2 is an isometric view of body 100 shown in the previous figure. In the embodiment of FIG. 2, body 100 is shaped to form an ocular implant 136 having an outer surface 138 defining a generally cylindrical volume. An inner surface 140 of body 100 defines an elongate channel 142. Ocular implant 136 may be inserted into Schlemm's canal of a human eye to facilitate the flow of aqueous humor out of the anterior chamber. This flow may include axial flow along Schlemm's canal, flow from the anterior chamber into Schlemm's canal, and flow leaving Schlemm's canal via outlets communicating with Schlemm's canal. When in place within the eye, ocular implant 136 will support trabecular mesh tissue and Schlemm's canal tissue and will provide for improved communication between the anterior chamber and Schlemm's canal (via the trabecular meshwork) and between pockets or compartments along Schlemm's canal.
  • [0038]
    Elongate channel 142 of ocular implant 136 fluidly communicates with a first opening 128 as well as inlet portion 101. Various fabrication techniques may be used to fabricate ocular implant 136. For example, ocular implant 136 can be fabricated by providing a generally flat sheet of material and laser cutting the sheet of material to form body 100 shown in FIG. 1. The body 100 may then be formed into a generally tubular shape as shown in FIG. 2. Any adjoining edges (such as edges 103) may be, optionally, welded. By way of a second example, ocular implant 136 may be fabricated by providing a tube and laser cutting openings in the tube to form the shape shown in FIG. 2.
  • [0039]
    As shown in FIG. 2, ocular implant 136 comprises a first spine 102 and a second spine 104. A first frame 106 of ocular implant 136 is disposed between first spine 102 and second spine 104.

    First strut 120 of first frame 106 comprises a first edge 124A and a second edge 126A. Second strut 122 has a shape that is a mirror image of the shape of first strut 120. In FIG. 2, first opening 128 of ocular implant 136 can be seen extending between first edge 124A of first strut 120 and a first edge 124B of second strut 122. A second edge 126B of second strut 122 and second edge 126A of first strut 120 define a second opening 130. Second opening 130 and additional openings (e.g., first opening 128) defined by ocular implant 136 allow aqueous humor to flow laterally across and/or laterally through ocular implant 136.
  • [0041]
    Ocular implant 136 can be fabricated from various biocompatible materials possessing the necessary structural and mechanical attributes. Both metallic and non-metallic materials may be suitable. Examples of metallic materials include stainless steel, tantalum, gold, titanium, and nickel-titanium alloys known in the art as Nitinol. Nitinol is commercially available from Memry Technologies (Brookfield, Conn.), TiNi Alloy Company (San Leandro, Calif.), and Shape Memory Applications (Sunnyvale, Calif.).
  • [0042]
    Ocular implant 136 may include one or more therapeutic agents. One or more therapeutic agents may, for example, be incorporated into a polymeric coating that is deposited onto the outer surfaces of the struts and spines of the ocular implant. The therapeutic agent may comprise, for example, an anti-glaucoma drug. Examples of anti-glaucoma drugs include prostaglandin analogs. Examples of prostaglandin analogs include latanprost.

The shape of ocular implant 136 may be described using the cylindrical coordinates shown in FIG. 4. These cylindrical coordinates include a radius r, an angle θ and an axial dimension Z. Cylindrical coordinates may be conceptualized as an extension of two dimensional polar coordinates to include a longitudinal or axial dimension Z. The two dimensions of a typical polar coordinate system are radius r and angle θ. In the embodiment of FIG. 4, dimension Z extends along a longitudinal axis 148 of cylindrical volume V.
  • [0047]

  • [0054]
    In the embodiment of FIG. 8, a blunt tip 252 is disposed at a distal end of ocular implant 236. In some useful embodiments of ocular implant 236, blunt tip 252 has a generally rounded shape. In the embodiment shown in FIG. 8, blunt tip 252 has a generally hemispherical shape. The generally rounded shape of blunt tip 252 may increase the likelihood that body 200 will track Schlemm's canal as ocular implant 236 is advanced into the canal during an implant procedure.
  • [0055]
    In FIG. 8, ocular implant 236 is pictured assuming a generally straight shape. Embodiments of ocular implant 236 are possible which have a generally curved resting shape. Ocular implant 236 may be fabricated, for example, by laser cutting a tube to create the shape shown in FIG. 8. When this is the case, it may be desirable to rotate a straight tubular workpiece during the laser cutting process. After the laser cutting process, the ocular implant can be heat-set so that the ocular implant is biased to assume a selected shape (e.g., a generally curved shape).
  • [0056]
    FIG. 9 is a plan view of ocular implant 236 shown in the previous figure. In the embodiment of FIG. 9, ocular implant 236 has an at rest shape that is generally curved. This at rest shape can be established, for example, using a heat-setting process. The ocular implant shape shown in FIG. 9 includes a distal radius RA, a proximal radius RC, and an intermediate radius RB. In the embodiment of FIG. 9, distal radius RA is larger than both intermediate radius RB and proximal radius RC. Also in the embodiment of FIG. 9, intermediate radius RB is larger than proximal radius RC and smaller than distal radius RA. In one useful embodiment, distal radius RA is about 0.310 inches, intermediate radius RB is about 0.215 inches and proximal radius RC is about 0.105 inches.
  • [0057]
    In the embodiment of FIG. 9, a distal portion of the ocular implant follows distal radius RA along an arc extending across an angle AA. A proximal portion of the ocular implant follows proximal radius RC along an arc extending across an angle AC. An intermediate portion of the ocular implant is disposed between the proximal portion and the distal portion. The intermediate portion follows radius RB and extends across an angle AB. In one useful embodiment, angle AA is about 55 degrees, angle AB is about 79 degrees and angle AC is about 60 degrees.
  • [0058]
    Ocular implant 236 may be used in conjunction with a method of treating a patient. Some such methods may include the step of inserting a core member into a lumen defined by ocular implant 236. The core member may comprise, for example, a wire or tube. The distal end of the ocular implant may be inserted into Schlemm's canal. The ocular implant and the core member may then be advanced into Schlemm's canal until the ocular implant has reached a desired position. The core member may then be withdrawn from the ocular implant.
  • [0059]
    FIG. 10 shows ocular implant 236 of the previous figure in place within a human eye. The eye of FIG. 10 includes an anterior chamber that is covered by a cornea. The iris of the eye is visible through the cornea and the anterior chamber. The anterior chamber is filled with aqueous humor which helps maintain the generally hemispherical shape of the cornea.
  • [0060]
    Whenever a person views an object, he or she is viewing that object through the cornea, the aqueous humor, and the lens of the eye. In order to be transparent, the cornea and the lens can include no blood vessels. Accordingly, no blood flows through the cornea and the lens to provide nutrition to these tissues and to remove wastes from these tissues. Instead, these functions are performed by the aqueous humor. A continuous flow of aqueous humor through the eye provides nutrition to portions of the eye (e.g., the cornea and the lens) that have no blood vessels. This flow of aqueous humor also removes waste from these tissues.
  • [0061]
    Aqueous humor is produced by an organ known as the ciliary body. The ciliary body includes epithelial cells that continuously secrete aqueous humor. In a healthy eye, a stream of aqueous humor flows out of the eye as new aqueous humor is secreted by the epithelial cells of the ciliary body. This excess aqueous humor enters the blood stream and is carried away by venous blood leaving the eye.
  • [0062]
    The structures that drain aqueous humor from the anterior chamber include Schlemm's canal and a large number of veins that communicate with Schlemm's canal via a plurality of outlets. In FIG. 10, Schlemm's canal 20 can be seen encircling the iris of the eye. Ocular implant 236 may be inserted into Schlemm's canal 20 to facilitate the flow of aqueous humor out of the anterior chamber. This flow may include axial flow along Schlemm's canal, flow from the anterior chamber into Schlemm's canal, and flow leaving Schlemm's canal via outlets communicating with Schlemm's canal. When in place within the eye, ocular implant 236 will support trabecular mesh tissue and Schlemm's canal tissue and will provide for improved communication between the anterior chamber and Schlemm's canal (via the trabecular meshwork) and between pockets or compartments along Schlemm's canal.
  • [0063]
    FIG. 11 is an enlarged plan view showing a portion of the eye shown in the previous figure. With reference to FIG. 11, it will be appreciated that ocular implant 236 extends through Schlemm's canal 20 across an angle G. Various implant sizes are possible, and different implant sizes may span a different angle G when placed in Schlemm's canal. Examples of angular spans that may be suitable in some applications include 60°, 90°, 150° and 180°.
  • [0064]
    In FIG. 11, an inlet portion 250 of ocular implant 236 is shown extending through trabecular mesh 22. Aqueous humor may exit anterior chamber 24 and enter Schlemm's canal 20 by flowing through inlet portion 250 of ocular implant 236. Aqueous humor may also exit anterior chamber 24 and enter Schlemm's canal 20 by flowing through the trabecular mesh 22 of the eye. With reference to FIG. 11, it will be appreciated that the spines of ocular implant 236 support trabecular mesh 22.
  • [0065]
    Aqueous humor exits Schlemm's canal 20 by flowing through a number of outlets. After leaving Schlemm's canal 20, aqueous humor travels through a network passages and veins and is absorbed into the blood stream. Schlemm's canal typically has a non-circular cross-sectional shape whose diameter can vary along the canal's length and according to the angle at which the diameter is measured. In addition, there may be multiple partial pockets or partial compartments (not shown in these figures) formed along the length of Schlemm's canal. The shape and diameter of portions of Schlemm's canal and the existence and relative location of partial pockets or compartments may limit or prevent fluid flow from one point of Schlemm's canal to another. Hence, each outlet from Schlemm's canal may drain only a portion of Schlemm's canal. This condition may be improved by placing ocular implant 236 in Schlemm's canal. Ocular implant 236 shown in FIG. 11 includes a plurality of struts, spines and openings. When in place within the eye, ocular implant 236 will support trabecular mesh tissue and Schlemm's canal tissue and will provide for improved communication between the anterior chamber and Schlemm's canal and between pockets or compartments along Schlemm's canal.
  • [0066]
    In FIG. 11, first opening 228 of ocular implant 236 is shown facing radially outward in Schlemm's canal 20. Aqueous humor can exit Schlemm's canal 20 by flowing through outlets that radiate away from and communicate with Schlemm's canal 20. After flowing through these outlets, this excess aqueous humor can enter the venous bloodstream be carried out of the eye by venous blood flow. The diameter of ocular implant 236 can range from 0.005 inches to 0.04 inches, preferably from 0.005 inches to 0.02 inches, in order to lie within and support Schlemm's canal.
  • [0067]
    While exemplary embodiments of the present invention have been shown and described, modifications may be made, and it is therefore intended in the appended claims to cover all such changes and modifications which fall within the true spirit and scope of the invention.
