Abstract
A tissue penetration device includes a penetrating member driver and a cartridge. A plurality of penetrating members are integrated with the cartridge. Each penetrating member is coupled to the penetrating member driver when advanced along a path into a tissue target. A penetrating member sensor is coupled to the plurality of penetrating members. The penetrating member sensor is configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.
Claims170
A tissue penetration device, comprising:
- a penetrating member driver;
- a cartridge;
- a plurality of penetrating members integrated with the cartridge, each of penetrating member coupled to the penetrating member driver when advanced along a path into a tissue target;
- and
- a penetrating member sensor coupled to the plurality of penetrating members, the penetrating member sensor configured to provide information relative to a depth of penetration of a penetrating member through a skin surface.
A tissue penetrating system, comprising:
- a plurality of penetrating members;
- a penetrating member driver coupled to the plurality of penetrating members;
- a cartridge transport device;
- and
- a plurality of cartridges each associated with a penetrating member, the cartridge transport device being configured to move each cartridge to a position aligning a penetrating member with the penetrating member driver to drive the penetrating member along a path into a target tissue site.
A tissue penetrating device, comprising:
- a penetrating member;
- a penetrating member driver coupled to the penetrating member;
- a penetrating member sensor coupled to the penetrating member, the penetrating member sensor configured to provide information relative to a depth of penetration of a penetrating member through a skin surface;
- and
- a processor coupled to the penetrating member sensor, the processor producing a signal indicative of a change in direction and magnitude of force exerted on the penetrating member, the processor further configured to cause application of a braking force to the penetrating member.
A skin penetrating device, comprising:
- a penetrating member driver;
- a penetrating member coupled to the penetrating member driver;
- and
- a damper coupled to the penetrating member driver for preventing multiple oscillations of the penetrating member in the tissue target once the penetrating member has reached a desired depth.
A method of penetrating a target tissue, comprising:
- advancing a penetrating member through the target tissue;
- stopping the penetrating member at a desired depth below a skin surface without multiple oscillations against the skin surface;
- and
- withdrawing the penetrating member from the target tissue.
A method of penetrating a target tissue, comprising:
- providing a tissue penetrating system including a penetrating member driver, a plurality of cartridges, a plurality of penetrating members each associated with a cartridge, a plurality of sample chambers each associated with a penetrating member, and a penetrating member sensor;
- advancing a penetrating member from a cartridge into the target tissue;
- withdrawing the penetrating member from the target tissue;
- and
- receiving an analyte sample in a sample chamber.
