Abstract
A tissue penetrating system includes a plurality of cartridges each with a distal port and a proximal port. A plurality of penetrating members are provided, each coupled to a cartridge and having a sharpened distal tip and a shaft portion slidably disposed within the cartridge. A seal is formed by a fracturable material between the penetrating member and the cartridge. The seal is positioned at one or both of a distal port or a proximal port of the cartridge.
Claims17
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 penetrating member driver, each penetrating member having a sharpened distal tip and a shaft portion slidably disposed within the cartridge;
- a plurality of analyte sensors each being associated with a penetrating member;
- 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
- a penetrating member position sensor coupled to the penetrating member driver, the position sensor utilizing position information of the each of a penetrating member to determine a depth of penetration through a skin surface.
