Flow regulating implant, method of manufacture, and delivery device

Номер: US20120053505A1
Автор: Ira Yaron, Orit Yarden
Принадлежит: Optonol Ltd

An implant includes a tube for permitting fluid flow. A flow controlling rod may be inserted within the tube passage. One or more holes around the circumference of the tube may be selectively permanently or temporarily occluded to give desired flow characteristics. A delivery device for implanting the implant may include a central bore in which a retractable wire is located. The retractable wire penetrates a tube passage of the implant. After the implant is in position in the eye, the retention wire is retracted out of the implant. In a method for manufacturing an implant, two tubes of different diameters are utilized. The smaller tube fits inside the longitudinal bore of the larger tube. When the tubes are cut, the smaller tube forms the tube of the implant and the remaining portions of the larger tube form the retention projection and/or disk of the implant.

One method involves introducing an implant, with proximal and distal ends, into the anterior chamber and penetrating eye tissue using an implant distal portion. The implant is advanced from the anterior chamber into the penetrated eye tissue to locate the distal and proximal ends respectively in the physiologic outflow pathway and the anterior chamber. Aqueous humor is conducted between the proximal and distal ends.

A fenestration system can include: a drainage screwdriver; a drainage screw removably receivable onto the drainage screwdriver; and a drainage cap removably coupleable with the drainage screw when the drainage screw removed from the drainage screwdriver. The drainage screwdriver can receive the drainage screw so that the drainage screw can be screwed through tissue and/or cyst or abscess sac. The drainage screwdriver can then release the drainage screw so that it is inserted into the tissue, cyst, or abscess so as to be capable of drainage. A lumen in the drainage screw can function similarly to a drainage tube. The drainage cap can be applied to the drainage screw to close the lumen to inhibit other fluids or particles from entering into the tissue, cyst, or abscess via the lumen.

Micromechanic passive flow regulator

Номер: US20120316492A1
Автор: Eric Chappel
Принадлежит: Debiotech SA

The invention concerns a flow regulator, made of a stack of 3 plates, respectively a top plate including a flexible membrane ( 1 ), a middle plate ( 2 ) with pillars and through holes and a bottom plate ( 3 ) with fluidic ports, micro channels and through holes ( 8,9,12 ). The principle is based on the deformation of the membrane due to the pressure of the liquid. The membrane goes in contact with the pillars of the middle plate, obstructing gradually the through holes of the pillars. The device is designed to keep the flow constant in a predefined range of pressure. The device is dedicated to ultra low flow rate up to 1 ml per day or below, typically for drug infusion. Plastic flow regulators comprise preferably several independent valves coupled in parallel. The membrane plate is therefore made of several flexible membranes obstructing gradually the flow by increasing the pressure. Stress limiters are used to avoid plastic deformation of the membrane. For implanted pump, the use of a flow regulator instead of a flow restrictor has several advantages, including the possibility to reduce significantly the reservoir pressure and to generate directly the pressure during the pump filling by using an elastic drug reservoir.

Автор: Michael DeFusco, Stephen F. Wilson
Принадлежит: Codman and Shurtleff Inc

A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.
