Abstract

Se provee una micro-aguja que es particularmente útil para la toma de muestra mínimamente invasiva de un fluido biológico y/o el suministro mínimamente invasivo de una droga u otra formulación a través de la piel. La micro-aguja tiene una estructura que tiene una base en un extremo proximal y un vértice en un extremo distal, y un lumen abierto que se extiende allí a través de ella y a través de la cual se puede transferir fluido. La estructura define un eje estructural que intersecta el eje luminal definido por el lumen abierto. El punto de intersección entre estos ejes está en un punto por debajo del vértice de la micro-aguja para proveer un ápice afilado en el extremo distal de la micro-aguja y define la configuración general del extremo distal de la micro-aguja, el cual puede ser seleccionado o hecho a medida de acuerdo con el uso pretendido para la micro-aguja. La micro-aguja puede ser integral con un dispositivo de medición para medir la concentración de un constituyente adentro de un fluido biológico del que se tomó muestra y/o con un depósito de fluido para contener un fluido a ser suministrado, y también puede usarse en conjunto con un medio de control a distancia. También se proveen métodos de hacer y usar la micro-aguja del presente, así como también equipos que comprende una o más micro-agujas.
