20120000487 | CANNULA CLEANING DEVICE - A method for making a device for cleaning the cannula of a medical instrument and for cleaning a cannula with the device in which the distal end of an elongated support and guiding member, having proximal and distal ends, is secured in a cleaning element formed of a substantially reticulated hydrophobic polyurethane foam having a plurality of pores within its structure which define surfaces in the foam. The surfaces of the polyurethane foam are coated with a hydrophilic polyurethane coating and a liquid enzymatic cleaning solution is absorbed in the coating and then dried. When used to clean a cannula the cleaning element is immersed in water to wet the enzymatic cleaner inserted into the cannula and manipulated from the proximal end of the elongated support. | 01-05-2012 |

20140256025 | METHODS AND ENZYMATIC DETERGENTS FOR REMOVING BIOFILM - A composition for cleaning a medical instrument having a surface at least partially covered by a biofilm. The composition may include a first enzyme having a weight of less than about 10% of the total weight of the composition, a second enzyme having a weight of less than about 10% of the total weight of the composition, and a surfactant having a weight less than about 10% of the total weight of the composition. The second enzyme may be different from the first enzyme. Additionally, the composition may have a pH ranging from about 4 to about 12, and the composition may be configured to remove greater than about 90% of the biofilm from the medical instrument in less than about 10 minutes. | 09-11-2014 |

20130063321 | MULTI-ARM CONFORMAL SLOT ANTENNA - An octave bandwidth conformal cavity-backed slot antenna includes a ground plane with a number of different length slits that come together at the central feedpoint. The slit length varies from one-half a wavelength at the highest frequency at which the antenna is to operate for the short side to one wavelength at the highest frequency for the long side, with the proximal ends of the slits having a common feedpoint. Such slot antennas may be arrayed in a quad configuration. Because the trapezoidal envelope of the antenna induces the phase-center to shift with frequency, when two are arrayed with short sides adjacent, the spacing between them results in a phase center from one antenna to the next that is effectively within half a wavelength at all frequencies. | 03-14-2013 |
