A surgical sizer for creating a tissue pocket for an implantable medical device may include a replica of the device and a (preferably ergonomic) handle portion, optionally with marking features that facilitate marking the tissue for precise implant placement and alignment.

Instruments and methods for surgical sizing and marking

Surgical introducers aid surgeons in the implantation of medical devices. The introducer provides support and an even distribution of force for ease of insertion and prevention of damage to the medical device while protecting the tissue into which the device is implanted. A representative embodiment includes or consists of a locking device, a pair of forceps, a specially configured and/or angled head with a seat for the device to be implanted, and a gripping area.

Surgical implantation instrument

A system for refilling the drug reservoir of an implanted drug pump device may facilitate wireless data exchange between the refill system and the implanted device, e.g., to verify proper drug selection prior to commencement of the refill process. Via the wireless link, the drug pump device and refill system can exchange data such as, for example, refill information (including, e.g., a type of drug), a drug pump device history, a drug dosage log, and/or a drug-delivery protocol. Further, the refill system can facilitate reprogramming the implanted device wirelessly.

Implantable drug pumps and refill devices therefor

In various embodiments, a drug-delivery device includes one or more reservoirs that may each contain a therapeutic agent for delivery to a patient.

Apparatus and methods for delivering therapeutic agents

In various embodiments, a tool is employed in filling a drug-delivery device. The tool may include, for example, a needle that is admitted through a fill port of the drug-delivery device.

Implantable drug-delivery devices, and apparatus and methods for filling the devices

An implantable device has an outer shell that includes an aperture through the housing of the device and, spanning the aperture, a membrane structure permeable to gas but not to liquid. In this way, excess gas may be vented from the device. The membrane and aperture are designed to discourage or even prevent tissue ingrowth.

Vented implantable drug-delivery device and related methods

Advances in filling apparatus, handheld tools, surgical techniques and intraoperative biometry for implanting and adjusting an accommodative liquid lens are disclosed. The lens may be attached to or retained within a handheld surgical tool, which can be fluidly connectable to a filling console to fill the lens with a liquid. In various embodiments, a filling console facilitates aspirating liquid out of the lens in order to ensure the absence of residual bubbles and filling of the lens with fluid during surgery, as well as during post-operative adjustments to the lens. Actuated by the surgeon, the filling console can aspirate fluid from the lens and inject fluid into the lens following insertion thereof.

Filling and implanting accommodative intraocular lenses

Embodiments of method of manufacturing an implantable pump, including providing an upper layer comprising a dome structure for housing a drug chamber and a cannula in fluid communication with the drug chamber, providing a middle deflection layer adjacent the drug chamber, providing a bottom layer comprising electrolysis electrodes, and bonding the upper layer, middle deflection layer, and bottom layer to form the pump.

Drug-delivery pumps and methods of manufacture

Embodiments of the present invention utilize a closed-loop feedback control system to ensure accurate drug delivery. This control system may, for example, utilize a flow sensor to measure the volume of delivery and an intelligent control algorithm to anticipate and compensate for overdoses and underdoses. Feedback control systems in accordance herewith can be applied to any piston- or plunger-driven pump system utilizing sensors that measure flow directly or indirectly. In some embodiments, adjustments are made during a 'priming' stage when liquid is pumped through the internal fluid path but does not exit the pump.

Drug-delivery pump with intelligent control

In various embodiments, implants including reservoirs, such as intraocular lenses, feature flexible membranes and valves integrated therewith, the valves having apertures that are normally closed.

Flexible valve structure for implantable reservoir

In various embodiments, an implantable pump includes a cannula. The pump (e.g., the cannula thereof) may include, for example, flow sensors, pressure sensors, filters, and/or other components.

Implantable pumps and cannulas therefor

A removable material is deposited or otherwise applied to a flat substrate surface in a pattern corresponding to desired corrugations in a membrane, e.g., a deflection diaphragm. The applied material serves as a scaffold for a polymeric material, which is applied thereover, and following cure or hardening, the polymeric material is removed to form a finished corrugated membrane.

Method of making a corrugated deflection diaphragm

Implantable drug-delivery pump

The lens geometry and power of an intraocular lens is optimized to provide both distance and near vision correction for a patient. The optimization may be based on one or more measured accommodation-related parameters and one or more estimated accommodation-related parameters. An accommodative amplitude may be predicted based on the measured and estimated accommodation-related parameters, and the optimized the intraocular lens geometry and power established based thereon.
