| 20100138163 | METHODS, SYSTEMS, AND COMPUTER READABLE MEDIA FOR MONITORED APPLICATION OF MECHANICAL FORCE TO SAMPLES USING ACOUSTIC ENERGY AND MECHANICAL PARAMETER VALUE EXTRACTION USING MECHANICAL RESPONSE MODELS - The subject matter described herein includes methods, systems, and computer readable media for monitored application of mechanical force to samples using acoustic energy and mechanical parameter value extraction using mechanical response models. One aspect of the subject matter described herein includes a method for determining mechanical property parameters of a sample. The method includes applying acoustic energy to a sample to apply a mechanical force to the sample. The method further includes measuring a response by the sample during the application of the acoustic energy to determine a value for a first mechanical property parameter of the sample. The method further includes measuring a recovery response of the sample following cessation of the application of the acoustic energy to determine a value for at least one second mechanical property parameter of the sample. The method further includes determining a value for at least one additional mechanical property parameter of the sample based on a mathematical relationship between the first, at least one second, and at least one additional mechanical property parameter. | 06-03-2010 |

| 20090112181 | Device and method for delivering or withdrawing a substance through the skin - An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. A device includes a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. | 04-30-2009 |
| 20090270792 | MICROPROTRUSION ARRAYS AND METHODS FOR USING SAME TO DELIVER SUBSTANCES INTO TISSUE - Improved microprotrusion abrasion devices having fluid retaining or directing patterns, and specific design parameters and method for delivery of substances into the skin. Various configurations of such devices are disclosed, including domed, channeled, patterned and stepped. | 10-29-2009 |
| 20100292648 | Device and method for delivering or withdrawing a substance through the skin - An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. A device includes a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. | 11-18-2010 |
| 20110098641 | DISPOSABLE INJECTION DEVICE - An injection device is provided. The device includes a housing having a first end defining a first opening. A plunger is received within the first opening of the housing to move between first and second positions. A cartridge is disposed in the housing and has an interior serving as a reservoir for a drug. A delivery needle is disposed within the housing and is in fluid communication with the reservoir via an interruptible fluid channel. A locking mechanism is disposed in the housing. In the first position of the plunger the delivery needle is enclosed by the plunger and in the second position of the plunger the delivery needle is placed in an injection position and the plunger activates the locking mechanism whereby when the plunger returns to the first position the locking mechanism prevents the needle from being placed in the injection position. | 04-28-2011 |

| 20100030148 | Intradermal Delivery Device With Crenellated Skin Engaging Surface Geometry - An apparatus for delivering or withdrawing a fluid through at least one layer of the skin is provided. The device may include a body having a top face, a bottom face, a side edge and at least one channel. The bottom face includes a first surface area and a second surface area adjacent to and recessed at a first distance from the first surface area. The bottom face further includes at least one raised protrusion disposed on the second surface area. The protrusion has a height from the first surface greater than the first distance. At least one dermal-access member is provided in the protrusion and is in fluid communication with the channel to deliver or withdraw the fluid. | 02-04-2010 |
| 20100286605 | VALVE FOR MIXING OF SUBSTANCES - A valve is provided herein for permitting mixing of at least two components, the valve including a body configured for slidable liquid tight engagement with an injector or drug cartridge barrel. The body includes a proximal end, a distal end, and a channel extending therebetween, the channel having a proximal portion and a distal portion. A poppet is sealingly and slidably disposed in the channel to selectively move between first and second positions. The poppet includes a proximal end, a distal end, and a fluid channel, the fluid channel being defined in the poppet and extending from an outlet opening located distally of the distal end of the body. With the poppet being in the first position, the poppet defines a liquid tight seal in the channel such that liquid flow through the channel is prevented. With the poppet being in the second position, the fluid channel is in communication with the proximal portion of the channel so as to define a liquid flow path from the proximal portion of the channel to the outlet opening. Advantageously, with the subject invention, a valve is provided which permits controlled separation and mixing of substances in a standard injector or drug cartridge barrel, without any modification required thereto. | 11-11-2010 |

| 20110071494 | Intradermal Delivery Device - A system and method is provided for an injectable substance delivery device comprising a limiter, shoulder or post, that controls how deep the needle is inserted into the tissue. The limiter is sized in proportions that control the maximum insertion depth of the needle into the tissue without excessively restricting the complete insertion of the needle. The system and method further comprises an normalization or stabilizer ring that prevents distortion of the tissue in the vicinity of the infusion, so that the needle length is the major determining factor as to how deep the infusion is delivered. | 03-24-2011 |
