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.
Claims168
A tissue penetrating system, comprising:
- a plurality of cartridges each with a distal port and a proximal port;

A tissue penetrating system, comprising:
- a cartridge having a distal port and a proximal port;
- a plurality of penetrating members;
- a plurality of lumens between the distal port and the proximal port for slidably receiving a penetrating member;
- a sample chamber defined by the cartridge having an opening;

4 more elements
A tissue penetrating system, comprising:
- a plurality of cartridges;
- a penetrating member driver;
- a plurality of penetrating members coupled to the penetrating member driver, each of a penetrating member associated with a cartridge;
- a plurality of gas-tightly sealed enclosures coupled in an array, each of the enclosures fully containing at least one of the plurality of cartridges;
- the sealed enclosures configured to be advanceable on a transport device that individually releases the cartridges from the sacks and loads them individually onto the penetrating member driver.
2 more elements
A tissue penetrating system, comprising:
- a plurality of penetrating members each having a sharpened distal tip;
- a penetrating member driver;
- and
- a plurality of cartridges coupled in an array and each housing a penetrating member, each cartridge configured to permit the penetrating member driver to engage each of the penetrating members sequentially, each cartridge having a plurality of seals positioned to provide that the sharpened distal tip remains in a sterile environment before penetrating a target site, each penetrating being launched without breaking a seal.
1 more element
A tissue penetrating system, comprising:
- a plurality of cartridges each with a distal port and a proximal port;
- a plurality of penetrating members each associated with a cartridge, 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 each cartridge, the seal being positioned at least one of a distal port or a proximal port of the cartridge;
- and
- a cartridge transport device for moving each of the cartridges to a position that aligns the penetrating member with the penetrating member driver so that the penetrating member can be driven along a path into a target tissue.
2 more elements
A method of penetrating a tissue site, comprising:
- providing a tissue penetrating system that includes a cartridge, a sample chamber, a penetrating member and at least one seal that maintains the penetrating member in a sterile condition prior to launch of the penetrating member;
- fracturing at least a portion of the seal prior to launch of the penetrating member;
- launching the penetrating member to a target tissue;
- and
- receiving a body fluid in the sample chamber of the tissue penetrating system.
