In some embodiments (e.g. for improved cleanability) the peak structures of the microstructured surface have a side wall angle of greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-comers elements. The microstmctured surface of the medical diagnostic device typically comes in contact with multiple patients during normal use of the device, such as a stethoscope diaphragm. The microstmctured surface exhibits better microorganism (e.g. bacteria) removal when cleaned and/or provides a reduction in microbial touch transfer. Also described are methods of making and methods of use.

Microstructured surface with increased microorganism removal when cleaned, articles and methods

Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Surgical cassette

A cassette having a molded flow channel contained on an elastomeric sheet that is bonded or mechanically attached to a rigid substrate. The flow channel projects outwardly from the exterior of the cassette so that a peristaltic pump having pump head rollers mounted radially from the axis of rotation of the pump motor compress the elastomeric flow channels against the rigid substrate during operation.

Fluid pressure sensing chamber

A pressure sensing chamber having a tubing extension with a reduced diameter portion extending through the chamber. The tubing contains a plurality of ports so as to allow the purging of air from the chamber, but the ports are sized so that bubbles entering the tubing cannot easily flow into the chamber. The reduced diameter portion creates a pressure differential between the holes. This differential pressure creates flow through the chamber under high liquid flow and turbulent liquid flow events.

Method of testing a surgical system

A method of testing a surgical system that takes advantage of the fact that in a balanced irrigation/aspiration system (inflow≧outflow) the duration of the aspiration pressure recovery to the irrigation fluid source pressure immediately following pump stop is independent of pump run time. This method provides a more reliable way of detecting restricted irrigation flow configurations not detectable by the current methods, such as marginal irrigation flow cases that could potentially lead to surgical complications (e.g. chamber collapse during post-occlusion break surge).

Method of testing a surgical system

A method for direct indication of the IOP level without requiring an additional pressure transducer being introduced into the irrigation path. The method of the present invention estimates resistance ratio for a particular setup, and thus does not assume a typical value; the estimation is performed in a pre-operational configuration that is the closest possible to the surgical configuration.

Surgical cassette

Cassette information that may be encoded include features such as lot number and performance characteristics, such as pressure sensor calibration data, flow and pressure data and any other performance characteristics of the cassette captured during testing of the cassette at manufacture.

Ophthalmic fluidics system with eddy current pressure sensor

Systems and methods are disclosed for measuring fluid pressure in an ophthalmic surgical system. An example system comprises a fluid flow path and a pressure sensor system for measuring pressure in the fluid flow path. The pressure sensor system comprises a conductive, movable diaphragm having a first side and a second side, the first side of the diaphragm facing the fluid flow path, and an eddy current position sensor positioned on the second side of the diaphragm without contacting the diaphragm. The eddy current position sensor comprises a position sensor coil activatable by high frequency alternating current and signal conditioning electronics capable of sensing inductance or impedance or resonant frequency variation in the position sensor coil as a gap between the diaphragm and the position sensor coil changes and of translating that variation into a displacement signal correlated to fluid pressure. A method of measuring fluid pressure may be performed using one or more of the systems described herein.

The pressure sensor is adapted to monitor for an occlusion in the aspiration line upstream of the first aspiration pump. The second aspiration pump may be operated at the same flow rate as the first aspiration pump and/or to maintain a constant pressure between the second aspiration pump and the first aspiration pump. Systems and methods as disclosed allow for a handpiece pump located close to the working tip while providing reliable occlusion detection with a pressure sensor located away from the handpiece.
