Abstract:
1. A tissue penetrating system, comprising: a plurality of cartridges each with a distal port and a proximal port; a plurality of penetrating members each coupled to a cartridge and a drive force generator, each penetrating member having a sharpened distal tip and a shaft portion slidably disposed within the cartridge; a seal formed by a fracturable material between the penetrating member and the cartridge, the seal being positioned at least one of a distal port or a proximal port of the cartridge and sealing the penetrating member prior to launch of the penetrating member through a skin surface; and a user interface coupled to a processor that includes control instructions, wherein the processor through the control instructions provides an input to the drive force generator of, a depth of penetration of a penetrating member through a skin surface by using a distance from a tip of the penetrating member to the target tissue prior to initiation of penetrating member movement, in combination with knowing acceleration and displacement of the penetrating member, in combination with knowing an initial start position of the penetrating member.
