Hybrid power supply for surgical implants

Abstract

A hybrid power system for delivering an implant to the eye using hydraulic fluid flow or pressure. The implant can be stored, advanced, and delivered to the eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger can rigidly advance the implant to a sealed position in a first stage, and then the implant can be advanced into the eye by fluid pressure or fluid flow in a second stage. The power system can provide a first cell having a first power density and a second cell having a second power density, the second power density being greater than the first power density. A controller can use the first cell during the first delivery stage and the second cell during the second delivery stage.

Description

Technical Field

[0001] This application claims the benefit of priority of U.S. Provisional Patent Application No. 63 / 129,026, filed on December 22, 2020, entitled "HYBRID POWER DELIVERY FOR SURGICAL IMPLANTS", where the inventors are Austin Xavier Rodeheaver, Todd Taber, Roderick Van Der Bergh, Marshall Keith Proulx, Grant Corthorn, Chris Hemmingway, and Martin Orrell, and the entire disclosure of which is incorporated herein by reference as if fully and completely set forth herein.

[0002] The invention described in the appended claims generally relates to ophthalmic surgery. More particularly, without limitation, the claimed subject matter relates to systems, devices, and methods for implanting an implant into an eye.

Background Art

[0003] The human eye is susceptible to many diseases that can cause anything from mild degradation to complete loss of vision. Contact lenses and glasses can compensate for some diseases, but in other cases, ophthalmic surgery may be required. In some instances, implants may be beneficial or desirable. For example, an intraocular lens can replace a cloudy natural lens within the eye to improve vision.

[0004] The benefits of intraocular lenses and other implants are known, but improvements in delivery systems, components, and processes continue to be made to improve outcomes and benefit patients.

Summary of the Invention

Means for Solving the Problems

[0005] [[ID=二十九]] Novel and useful systems, apparatus and methods for ophthalmic surgery are described in the attached claims. Exemplary embodiments are also provided to enable those skilled in the art to fabricate and use the claimed subject matter.

[0006] For example, some embodiments may include, or may be essentially, a device for delivering an implant, such as an intraocular lens. In more detailed examples, the device may include a rigid plunger for advancing the implant. Some embodiments may additionally include a bore passing through the rigid plunger, which may allow a working fluid to advance the implant into the eye by fluid pressure. For example, a hollow rigid plunger may be used to first advance the intraocular lens to a point in the delivery lumen where a seal is created around the intraocular lens. The lens can then be advanced for delivery by fluid pressure by passing a working fluid through the hollow bore of the plunger.

[0007] Some embodiments may include, or may be essentially, a hybrid power module having a primary cell and a secondary cell. In some embodiments, for example, the primary and secondary cells may be a primary battery and a secondary battery, having different power densities. In other examples, the primary cell may be a battery, and the secondary cell may be a capacitor. Each cell may provide separate power supply capabilities at different points in time during the delivery procedure. For example, the primary cell may provide relatively low power for the initial movement of the implant over a relatively long range in a first stage, and the secondary cell may provide relatively high peak power for the delivery of the implant through the delivery lumen in a second stage.

[0008] More generally, some embodiments may include, or may be essentially, a device for operating an implant delivery device. Such embodiments may include a motor, a primary cell, a secondary cell, and a controller. The motor may be configured to be coupled to the implant delivery device. The primary cell may have a first energy density and a first power density, and the secondary cell may have a second energy density and a second power density. The controller may be coupled to the motor, the primary cell, and the secondary cell. The controller may be configured to selectively couple the primary cell to the motor in a first delivery range, couple the secondary cell to the motor in a second delivery range, and couple the primary cell to the secondary cell over a charging period. In more detailed embodiments, the second power density may be greater than the first power density.

[0009] Some embodiments of a device for delivering an implant to the eye may include a nozzle having a delivery lumen, an implant compartment coupled to the nozzle, an actuator, a motor configured to be coupled to the actuator, a primary cell, and a secondary cell. A controller may be coupled to the motor, the primary cell, and the secondary cell. The controller may be configured to selectively couple the primary and secondary cells to the motor. In some embodiments, the controller may couple the primary cell to the motor to operate the actuator to drive the implant from a first position to a second position, and the secondary cell to the motor to operate the actuator to drive the implant to a third position. In more detailed embodiments, the actuator may include a push rod configured to engage with the implant. For example, the push rod may be a rigid plunger in some embodiments. Additionally, some embodiments of the actuator may include a bore passing through the push rod, which may be fluidly coupled to the delivery lumen in the nozzle. For example, the push rod may be a hollow rigid plunger in some embodiments. The implant may be a lens in some embodiments.

[0010] A method for delivering or removing an implant from a delivery system may include providing the implant to the implant compartment, applying a first delivery force to advance the implant from the implant compartment to the delivery lumen using a rigid push rod, and applying a second delivery force to advance the implant through the delivery lumen. The second delivery force may be greater than the first delivery force. In some embodiments, the push rod may include or be essentially a rigid plunger. In more detailed embodiments, the method may additionally include moving a working fluid through a bore in the rigid plunger with the second delivery force.

[0011] Features, elements, and aspects described in relation to some embodiments may be omitted, combined, or replaced by alternative features. Other features, purposes, advantages, and preferred modes of fabricating and using the claimed subject matter are described in more detail below with reference to the accompanying drawings of exemplary embodiments.

[0014] The following description of exemplary embodiments provides information that will enable those skilled in the art to fabricate and use the subject matter described in the appended claims, although certain details already known in the art may be omitted. Therefore, the following detailed description is illustrative and not limiting.

[0015] Exemplary embodiments may also be described herein with reference to the spatial relationships between various elements or the spatial orientation of various elements depicted in the accompanying drawings. Generally, such relationships or orientations assume a coordinate system that corresponds to or is relative to a patient in an implant-receiving position. However, as will be understood by those skilled in the art, this coordinate system is not a strict definition but merely a descriptive convenience.

[0016] FIG. 1 is a schematic diagram of a system 100 capable of inserting an implant into an eye. In some embodiments, system 100 may include two or more modules, which can be configured to be appropriately coupled and decoupled for storage, assembly, use, and disposal. For example, as shown in FIG. 1, some embodiments of system 100 may include a nozzle 105, an implant compartment 110 coupled to the nozzle 105, and an actuator 115 coupled to the implant compartment 110. In some embodiments, system 100 may additionally include a drive module 120 configured to engage the actuator 115.

[0017] The nozzle 105 generally includes a tip adapted for insertion through an incision into the eye. The size of the tip can be adapted to surgical requirements and techniques as needed. For example, a small incision is generally preferred to shorten or minimize healing time. In some examples, an incision less than 3 millimeters may be preferred, and in some embodiments, the tip of the nozzle 105 may have a width less than 3 millimeters.

[0018] The implant compartment 110 generally represents a variety of devices suitable for storing the implant prior to delivery into the eye. In some embodiments, the implant compartment 110 may be configured, additionally or alternatively, to prepare the implant for delivery. For example, some embodiments of the implant compartment 110 may be configured to be actuated by a surgeon or other operator to prepare the implant for delivery by subsequent operation of the actuator 115. In some examples, the implant compartment 110 may be configured to actively deform, extend, expand, or otherwise manipulate the features of the implant before advancing the implant into the nozzle 105. For example, the implant compartment 110 may be configured to expand or widen one or more features, such as a support for an intraocular lens.

[0019] The actuator 115 is generally configured to advance the implant from the implant compartment 110 to the nozzle 105 and then from the nozzle 105 through the incision into the eye.

[0020] The drive module 120 is generally operable to actuate the actuator 115. In some examples, the drive module 120 can be operated by electrical, mechanical, hydraulic or pneumatic power or combinations thereof, or by some other means. In some examples, the drive module 120 can be manually operated. According to other implementations, the drive module 120 can be an automated system.

[0021] Generally, the components of the system 100 can be directly or indirectly coupled. For example, the nozzle 105 can be directly coupled to the implant compartment 110 and indirectly coupled to the actuator 115 through the implant compartment 110. The coupling can include fluid, mechanical, thermal, electrical or chemical bonds (such as chemical adhesion) or in some situations some combinations of the bonds. For example, the actuator 115 can be mechanically coupled to the drive module 120 and mechanically and fluidly coupled to the nozzle 105. In some embodiments, the components can also be coupled by physical proximity, integration into a single structure or formation from a single piece of material.

[0022] FIG. 2 is a schematic diagram of an example of a delivery module 200 that may be related to some embodiments of the system 100. In the example of FIG. 2, the delivery module 200 includes the nozzle 105, the implant compartment 110, and the actuator 115. The nozzle 105 of FIG. 2 has a delivery lumen 205 and the implant 210 is disposed within the implant compartment 110.

[0023] The actuator 115 in Figure 2 generally includes a housing 215 and a push rod, such as a plunger 220, located within the housing 215. In some embodiments, the plunger 220 or other push rod may be made of a substantially rigid material, such as a medical-grade polymer material. In the example in Figure 2, the actuator 115 further includes a bore 225 through which the plunger 220 passes and a drive interface 230. A plunger seal 235 may be located within the housing 215 and coupled to the plunger 220. A drive seal 240 may also be located within the housing 215.

[0024] As shown in the example in Figure 2, the drive seal 240 may be positioned between the plunger seal 235 and the drive interface 230, and the fluid chamber 250 may be defined within the housing 215 between the plunger seal 235 and the drive seal 240. In the exemplary configuration of Figure 2, the plunger seal 235 is configured to provide a fluid seal across the housing 215 and substantially prevent the movement of fluid from the fluid chamber 250 to the bore 225. The drive seal 240 may also be configured to provide a fluid seal across the housing 215 and substantially prevent the movement of fluid from the fluid chamber 250 to the drive interface 230.

[0025] Figure 3 is a detailed view of the actuator 115 of Figure 2, showing additional details that may be relevant to several embodiments. For example, the housing 215 of Figure 3 further includes a plunger interface 305 and a bypass channel 310 positioned between the plunger interface 305 and the drive interface 230. The bypass channel 310 can take various forms. For example, the bypass channel 310 may include a projection of the housing 215, as shown in Figure 3. In other examples, the bypass channel 310 may include a groove or recess on the inner surface of the housing 215. In some embodiments, the bypass channel 310 may include multiple channels. For example, in some embodiments, multiple channels may be arranged circumferentially around the housing 215.

[0026] The plunger 220 generally has a first end 315 and a second end 320, the first end 315 generally located adjacent to the plunger interface 305. The bore 225 generally penetrates the plunger 220 longitudinally from the first end 315 to the second end 320.

[0027] In some embodiments, the actuator 115 may additionally include a nozzle seal 325 and a bypass seal 330. Each of the nozzle seal 325 and the bypass seal 330 is generally configured to form a seal between a portion of the plunger 220 and the housing 215, substantially preventing the movement of fluid beyond the seal. As shown in the example in Figure 3, one or both of the nozzle seal 325 and the bypass seal 330 may be ring seals, such as O-rings, circumferentially positioned around a portion of the plunger 220. In other examples, umbrella seals may be preferred. In more detailed embodiments, the nozzle seal 325 may be positioned close to the first end 315 of the plunger 220, and the bypass seal 330 may be positioned close to the second end 320 of the plunger 220.

[0028] The drive interface 230 in Figure 3 includes a cap 335 and an aperture 340. The cap 335 may be coupled to the end of the housing 215 to hold the drive seal 240 and other components within the housing 215.

[0029] Figure 4 is a schematic diagram of an example of the drive module 120 of Figure 1, showing additional details that may be relevant to several embodiments. For example, the drive module 120 of Figure 4 generally includes a power module 400 and a motor 405 coupled to the power module 400. A drive shaft 410 may be coupled to the motor 405. In some embodiments, the drive shaft 410 may include or be essentially a lead screw. In some embodiments, the drive shaft 410 may be coupled to an actuator interface 415. The drive module 120 may also include a switch 420 for variable control of the speed of the motor 405 and an encoder wheel 425 for measuring the movement of the drive shaft 410.

[0030] Figure 5 is a schematic diagram showing an example of a power module 400 that may relate to several examples of the drive module 120. In the example of Figure 5, the power module 400 generally includes a primary cell 505, a secondary cell 510, and a controller 515 coupled to the primary cell 505 and the secondary cell 510. The primary cell 505 in Figure 5 may have a first energy density and a first power density, and the secondary cell 510 may have a second energy density and a second power density. In some embodiments, the first energy density may be greater than the second energy density, and the second power density may be greater than the first power density. For example, the primary cell 505 may be a battery that can provide a relatively high energy density and a low power density, and the secondary cell 510 may be a capacitor that can provide a relatively high power density and a low energy density. In some examples, the primary cell 505 may be a lithium-ion battery, and the secondary cell 510 may be a supercapacitor. As shown in Figure 5, some embodiments may additionally include a user interface 520, one or more power adjustment units 525, and one or more electronic switching elements such as solid-state relays 530.

[0031] The controller 515 may be configured to selectively couple the primary cell 505 to the motor 405 in a first delivery range and to couple the secondary cell 510 to the motor 405 in a second delivery range. For example, in some embodiments, the controller 515 may control a solid-state relay 530 to couple and disconnect the motor 405 to the primary cell 505 and the secondary cell 510. In some embodiments, the higher energy density and lower power density of the primary cell 505 can provide the motor 405 with relatively lower power over a longer duration, while the lower energy density and higher power density of the secondary cell 510 can provide the motor 405 with relatively higher power over a shorter duration. The controller 515 may also be configured to selectively couple the primary cell 505 to the secondary cell 510 over a charging period so that the primary cell 505 can charge the secondary cell 510. In some embodiments, the power module 400 may also include a switchable load resistor that can reduce leakage current during storage and autoclave cycles. Additionally or alternatively, the controller 515 may selectively couple the secondary cell 510 to a resistor in order to discharge the secondary cell 510. For example, the secondary cell 510 may be discharged before the autoclave cycle. A thermoelectric generator may also be used to charge the primary cell 505, the secondary cell 510, or both during the autoclave cycle.

[0032] Figure 6 is a simplified chart showing exemplary power profiles that may be relevant to several embodiments of the power module 400 of Figure 5. More specifically, the chart in Figure 6 shows the power that motor 405 can provide when motor 405 is selectively coupled to primary cell 505 and secondary cell 510 over different delivery ranges.

[0033] In some embodiments, the delivery range may be based on the movement of the drive shaft 410. For example, an encoder wheel 425 may provide the controller 515 with a signal indicating the position of the drive shaft 410, such as the distance of the drive shaft 410 from a nominal starting point D0. Additionally or alternatively, the delivery range may be based on an energy measurement, such as a current measured from the motor 405. For example, a current sensor (not shown) may provide the controller 515 with a signal indicating the power demand from the motor 405, and the controller 515 may switch between the primary cell 505 and the secondary cell 510 over different delivery ranges based on this signal. In the example in Figure 6, the controller 515 can couple the primary cell 505 to the motor 405 in a first delivery range of D0 to D1, and the motor 405 can provide delivery force to the drive shaft 410 in a first force range of F0 to F1. In the second delivery range D1-D2, the controller 515 can switch the motor 405 to the secondary cell 510, and the motor 405 can provide a delivery force to the drive shaft 410 in the second force range F1-F2. In the third delivery range D2-D3, the controller 515 can switch the motor 405 back to the primary cell 505, and the motor 405 can provide a delivery force in the first force range F0-F1. In the example in Figure 6, the second delivery range D1-D2 is shorter than the first delivery range D0-D1, and the first force range F0-F1 is smaller than the second force range F1-F2.

[0034] Figures 7A–7C are schematic diagrams illustrating an exemplary method for ejecting the implant 210 from the system 100. First, the various components of the system 100 can be assembled as needed. For example, the nozzle 105, implant compartment 110, and actuator 115 can be coupled to each other as shown in Figure 7A. The drive module 120 can also be coupled to the actuator 115 through the drive interface 230. For example, the drive shaft 410 may be configured to directly engage with the drive seal 240 through the drive interface 230, as shown in Figure 7A. In other examples, the actuator interface 415 may be configured to engage with the drive seal 240 through the drive interface 230. In some embodiments, the drive interface 230 may include an opening configured to receive the drive shaft 410, the actuator interface 415, or both.

[0035] The implant 210 may be provided within the implant compartment 110, as shown in the example in Figure 7A. In some embodiments, the implant 210 may include an intraocular lens that may have a shape similar to the shape of the natural lens of the eye and may be made from many materials. In the example in Figure 7A, the implant 210 exemplifies an intraocular lens having an optical body 705, an anterior support portion 710, and a posterior support portion 715. Examples of preferred materials may include silicone, acrylic, and combinations of such preferred materials. In some examples, the implant 210 may include a fluid-filled intraocular lens, such as a fluid-filled multi-level accommodative intraocular lens.

[0036] The plunger 220, plunger seal 235, and drive seal 240 are generally movable within the housing between a first position, as shown in the example in Figure 7A, and other positions shown in Figures 7B to 7C.

[0037] In some examples, the working fluid 720 may be stored in the fluid chamber 250. In the first position in Figure 7A, the plunger seal 235 fluidly isolates the bore 225 from the working fluid 720 in the fluid chamber 250, which may allow the working fluid 720 to be stored in the fluid chamber 250 in the first position. In some examples, the nozzle seal 325 and the first end 315 of the plunger 220 may protrude into the implant compartment 110 in the first position, as shown in Figure 7A, thereby forming a seal in the implant compartment 110 behind the implant 210. In some examples, the first end 315 of the plunger 220 may also engage with the implant 210 in the first position. In other examples, the nozzle seal 325 and the first end 315 may be housed in the housing 215 in the first position.

[0038] In some embodiments, the drive module 120 can move the drive shaft 410 against the drive seal 240, thereby rigidly moving the plunger 220, plunger seal 235, drive seal 240 and working fluid 720 to maintain a fixed relationship as shown in Figure 7B. For example, the controller 515 can engage the motor 405 with the primary cell 505 to provide a delivery force to the drive shaft 410 in a first range of F0 to F1, and the delivery force of the drive shaft 410 can move the plunger 220, plunger seal 235, drive seal 240 and working fluid 720 from a first position in Figure 7A to a second position in Figure 7B. In some embodiments, the movement from the first position to the second position may correlate with the movement of the drive shaft 410 over a first delivery range of D0 to D1 in Figure 6.

[0039] In the position shown in Figure 7B, the implant 210 is advanced into the delivery lumen 205, thereby forming a fluid seal between the implant 210 and the delivery lumen 205. In some examples, the implant 210 can be fully positioned within the delivery lumen 205. In the second position, the bypass channel 310 fluidly connects the bore 225 to the fluid chamber 250 around the plunger seal 235. When the drive shaft 410 and drive seal 240 pressurize the working fluid 720 in the fluid chamber 250, the working fluid 720 can move into the bore 225 through the bypass channel 310 at a higher flow rate without obstruction.

[0040] The plunger 220 may be held in the second position in Figure 7B against further force applied to the drive seal 240. For example, in some embodiments, the second end 320 of the plunger 220 may be flared, and the plunger interface 305 may be configured to engage with the second end 320 to limit its forward movement. Additionally or alternatively, the implant compartment 110 or nozzle 105 may include a plunger stopper 725 configured to engage with a portion or feature of the plunger 220, such as the second end 320 of the plunger 220, to prevent further forward movement. In yet another example, some embodiments of the delivery lumen 205 may be tapered, thereby preventing further forward movement of the plunger 220 into the delivery lumen 205. For example, the diameter of the delivery lumen 205 may decrease as it moves away from the implant compartment 110.

[0041] With the plunger 220 held, the additional pressure applied to the working fluid 720 by the drive seal 240 can move the working fluid 720 through the bypass channel 310 and the bore 225, as shown in the example in Figure 7C. The movement of the working fluid 720 from the bore 225 into the delivery lumen 205 under pressure from the drive seal 240 can increase the pressure and flow rate of the working fluid 720 in the delivery lumen 205 behind the implant 210, thereby allowing the implant 210 to advance further through the delivery lumen 205 until the implant 210 is ejected. In some embodiments, additional force from the drive shaft 410 may be advantageous in moving the working fluid 720 through the bore 225 and the delivery lumen 205 behind the implant 210, and in moving the implant 210 through the delivery lumen 205. To provide additional force, the controller 515 may switch the motor 405 to the secondary cell 510 to increase the power density available to the motor 405. For example, the secondary cell 510 may provide a higher power density than the primary cell 505, by providing a delivery force in a second range F1-F2 which can correlate with a second delivery range D1-D2 in Figure 6, and can be used to drive the drive shaft 410 from a second position in Figure 7B to a third position in Figure 7C.

[0042] Figures 8A and 8B are schematic diagrams further illustrating exemplary use of the system 100 for delivering an implant 210 into an eye 800. As shown, for example, an incision 805 may be made within the eye 800 by a surgeon. In some examples, the incision 805 may be made through the sclera 810 of the eye 800. In other examples, the incision may be formed in the cornea 815 of the eye 800. The incision 805 may be sized to allow insertion of a portion of the nozzle 105 to deliver the implant 210 into the lens capsule 820. For example, in some examples, the size of the incision 805 may have a length of less than about 3000 microns (3 millimeters). In other examples, the incision 805 may have a length of about 1000 to about 1500 microns, about 1500 to about 2000 microns, about 2000 to about 2500 microns, or about 2500 to about 3000 microns.

[0043] After the incision 805 is made, the nozzle 105 can be inserted through the incision 805 into the internal portion 825 of the eye 800. The system 100 can then eject the implant 210 into the lens capsule 820 of the eye 800 through the nozzle 105, as substantially described above with reference to Figures 7A-7C. In some applications, the implant 210 may be delivered in a folded configuration with one or more anterior support 710 and posterior support 715, and can return to its initial unfolded state within the lens capsule 820, as shown in Figure 8B. The lens capsule 820 can hold the implant 210 within the eye 800 in relation to the eye 800 such that the optics 705 refract light directed towards the retina (not shown). The anterior support 710 and posterior support 715 can engage with the lens capsule 820 to fix the implant 210 within the lens capsule 820. After the implant 210 is placed inside the lens capsule 820, the nozzle 105 can be removed from the eye 800 through the incision 805, and the eye 800 can heal over a period of time.

[0044] The systems, apparatus, and methods described herein may offer significant advantages. For example, some embodiments may be particularly advantageous for the delivery of intraocular lenses, including fluid-filled accommodative lenses, which may present unique challenges in delivery. Some embodiments can compress relatively large lenses to pass through an acceptablely small incision, manage deformation caused by fluid movement during compression and exiting the nozzle, and perform delivery in a predictable and controlled manner. Additionally, some embodiments can reduce the complexity of the system and the number of delivery steps while maintaining consistency in support position. Some embodiments may also reduce the amount of working fluid for delivery.

[0045] Additionally or alternatively, some embodiments may provide a hybrid power supply that may be advantageous for delivering several implants. For example, some embodiments of the power module 400 may provide both relatively lower power over longer distances and relatively higher peak power over shorter distances. In some embodiments of the system 100, the implant 210 may be larger than the delivery lumen 205 and may benefit from the hybrid power profile provided by some embodiments of the power module 400, which can provide lower power for moving the implant 210 into the delivery lumen 205 and even higher power for moving the implant 210 through the delivery lumen 205. Hybrid power may also accommodate long-term low-level energy requirements, which may be advantageous for some embodiments. More detailed benefits may include reducing the cost and complexity of batteries and other power cells.

[0046] In some embodiments, the operating force experienced by the operator can also be reduced. For example, the surgeon may only feel the operating force of the switch, which may be significantly smaller compared to some types of mechanical drive systems.
