The present technology is directed to an adjustable power intraocular lens comprising a container, an optical fluid in the container, and a transport substance in solution with the optical fluid. The container has an optical component and a peripheral component extending around at least a portion of the optical component. The optical component has an anterior optical element, a posterior optical element, and a fluid chamber having a chamber volume between the anterior optical element and the posterior optical element. The transport substance is configured to pass through the container. The adjustable power intraocular lens further comprises volume control elements in the container. The volume control elements are configured to be activated by a non-invasive energy and upon activation release the transport substance into the optical fluid to decrease the chamber volume and/or absorb the transport substance from the optical fluid to increase the chamber volume.

Intraocular drainage devices are provided. An intraocular drainage device includes a drainage tube that provides for increased drainage of aqueous humour from the anterior chamber of the eye. A self-clearing device is disposed within the drainage tube. The self-clearing device provides an increased fluid flow path within the drainage tube in response to clotting from the body or clogging from debris in the aqueous humour. Methods of manufacturing intraocular drainage devices and methods of inserting intraocular drainage devices into the eye are also provided.

An apparatus for influencing an intraocular pressure (IOP) of an eye with a controllable discharge device which is configured to discharge a liquid from at least one area of the eye. The apparatus includes a first sensor device which captures at least one first value that is characteristic for the IOP of the eye, and a second sensor device, which captures at least one second value that is characteristic for a pressure acting on the eye, and a control device which controls the discharge device at least at times taking account of the first characteristic value and the second characteristic value, wherein the second characteristic value is characteristic for an intracranial pressure and/or cerebrospinal pressure.

The present technology is directed to adjustable flow glaucoma shunts and methods for making and using such devices. In many of the embodiments described herein, the shunts include a generally flat frame. The frame can include an elongated portion having a lumen extending therethrough and a bladder portion defining an interior chamber that is in fluid communication with the lumen. When implanted in a patient's eye, aqueous can drain from the anterior chamber to a target outflow location via the lumen and interior chamber. In some embodiments, the shunts include a flow control assembly positioned within the interior chamber of the bladder portion to control the flow of aqueous through the lumen.

An occlusion system implantable in a human or animal body, including a fluidic circuit which includes an inflatable occlusive sleeve, a reservoir with variable volume filled with a fluid. The reservoir includes a fixed portion and a movable portion, an actuator mechanically coupled with the movable portion of the reservoir to linearly displace the movable portion relative to the fixed portion for adjusting the volume of the reservoir. The actuator and the reservoir are laid out in a sealed casing containing a gas. A sensor mechanically bound to the actuator and/or to the movable portion, measures a traction and/or compressive force of the movable portion of the reservoir. Also included is a device for measuring the fluid pressure in the fluidic circuit.

According to an aspect, an implant includes an inflatable member and a pump assembly configured to facilitate a transfer of a fluid from the reservoir to the inflatable member. The inflatable member has a sidewall that defines a lumen and a porous structure disposed within the lumen.

A blood flow control device having a catheter adapted to be advanced into a blood vessel to a blood flow control site within the blood vessel; an expandable anchor supported by the catheter, the expandable anchor being adapted to expand to engage a wall of the blood vessel, the expandable anchor having a blood impermeable wall defining an adjustable blood flow path extending through the expandable anchor from a proximal opening to a distal opening, the catheter being disposed outside of the adjustable blood flow path; a flow control element supported by the catheter, the flow control element being adapted to change a dimension of the adjustable blood flow path to change a rate of blood flow through the blood flow path; and a blood flow control actuator disposed at a proximal section of the catheter and adapted to actuate the flow control element.

A medical implant system for implantation in a patient to treat erectile dysfunction includes a first fluid path, an inflatable penile prosthesis cylinder, an electric pump, and implant controller, and an implantable power supply. The inflatable penile prosthesis cylinder is in fluid communication with the first fluid path and is configured for implantation in a corpus cavernosum of a patient. The electric pump is in fluid communication with the first fluid path. The implant controller is electrically coupled to the pump and is configured to activate the pump to drive a flow of fluid through the first fluid path and into the cylinder. The implantable power supply provides electrical power to the pump.

An implanted intraocular shunt can be manually manipulated, without surgical intervention, to modify the flow resistance of the shunt, thereby providing relief from high intraocular pressure while avoiding hypotony. For example, through application of pressure along a surface of the eye, a portion of the shunt can be displaced or separated relative to the shunt, thereby decreasing a flow resistance of the shunt.

An endoluminal valve (30) for controlling fluid flow during a surgical procedure is integrated into an access branch (24) of a tubular prosthetic device (10), the access branch (24) receiving a delivery system (100) including a shaft (110), a housing (112) with a depressible finger actuator (122) configured to contact a resilient wall surface (38) of inwardly tapering closure elements (40) of the integrated valve (30), and a fluid venting plug (133) on the shaft (110) which removably seats in an access opening (34) at the proximal end (32) of the endoluminal valve (30), wherein the proximal end (32) is secured within a lumen (26) of the access branch (24) and a distal end (36) of the endoluminal valve (30) located within the lumen (26) comprises self-sealing edges (42) coming together to form a flow-inhibiting seal.
