An intraosseous access device is operable to provide access to a sternal intraosseous space in a first mode of operation and operable to provide access to a peripheral intraosseous space in a second mode of operation. The device includes an outer sleeve, an inner penetrator hub, and an outer penetrator hub. A protective shield is telescopically coupled to the outer sleeve. The protective shield is operable to move from an expanded position to a retracted position in both the first and second modes of operation. A bone probe ring is disposed within the protective shield and configured to move between an extended position and a retracted position in both the first and second modes of operation. An actuator is operable to manually move the protective shield and the bone probe ring to the retracted position when in the second mode of operation.

Disclosed is a medical thread insertion instrument including: a medical thread having an outer surface thereof on which barbs are formed; a needle part having a cavity therein so that the medical thread is able to be inserted, the needle part including a needle having a predetermined length (L1); and a tube part having a cavity therein so that the needle is able to be inserted, the tube part being inserted into an inner side of the skin and including a tube having a length (L2) shorter than the length (L1) of the needle.

A device for needle biopsy is presented. The device includes a handle member having proximal and distal portions. A proximal handle member is disposed to the proximal portion of the handle member and a distal handle member is disposed to the distal portion of the handle member. A sheath lumen is disposed within the handle member and extends from the distal portion of the handle member. A needle housing member is partially disposed to the proximal portion of the handle member and a needle is disposed within the sheath lumen. A plurality of protrusions is disposed upon the needle. A needle protection member is partially disposed to the distal portion of the needle housing member. The needle protection member includes a needle protection hub and a needle protection shaft.

A staple cartridge assembly for use with a surgical stapler. The assembly has a cartridge body having a support portion with a plurality of staple cavities with openings. There is also a plurality of staples, wherein at least a portion of each the staple is removably stored within a staple cavity. Each the staple is movable between an unfired position and a fired position, and is deformable between an unfired configuration and a fired configuration. The assembly also includes a compressible tissue thickness compensator configured to be captured within the staples. The compressible tissue thickness compensator at least partially covers the staple cavity openings. The compressed tissue thickness compensator is configured to assume different compressed heights within different staples. The compressible tissue thickness compensator comprising a lyophilized foam having an anti-microbial agent embedded therein.

A self-adjusting device configured to be placed in contact with tissue/organ and apply mechanical force to the tissue/organ to achieve an improvement of functioning of the tissue/organ. The self-adjusting capabilities can be carried out by three functional subsystems that can be packaged either in a single, integrated system or in separate modules. A sensing subsystem senses the tissue/organ and sends at least one type of sensing signal characteristic of functioning of the tissue/organ to a controlling subsystem. The controlling subsystem processes the signal with an algorithm to determine if a configuration of the device needs to be changed or a force applied to the tissue/organ needs to be changed. An actuating subsystem can be controlled by the controlling subsystem to affect the configuration/force change when needed. A feedback loop is provided to keep the controlling subsystem up to date as to the state of the actuating subsystem.

A fastener cartridge can comprise fastener cavities arranged in longitudinal rows. A first fastener having a first configuration and a second fastener having a second configuration can be stored within a longitudinal row. First fasteners having a first configuration can be stored within a first longitudinal row and second fasteners having a second configuration can be stored within a second longitudinal row. Each first fastener can have a proximal leg, or leg portion, extending at a first proximal angle and a distal leg, or leg portion, extending at a first distal angle and each second fastener can have a proximal leg, or leg portion, extending at a second proximal angle and a distal leg, or leg portion, extending at a second distal angle. The first proximal angle can be different than the second proximal angle and/or the first distal angle can be different than the second distal angle.

A fastener cartridge comprising a cartridge body comprising a tissue-supporting deck, a longitudinal slot, cavities, and ridges protruding from the tissue-supporting deck is disclosed. The fastener cartridge further comprises fasteners positioned in the cavities, drivers supporting the fasteners, and a sled configured to engage the drivers to fire the fasteners from the cavities during a firing stroke. The sled comprises a central portion and ramps. The ramps comprise a first ramp on a first side of the central portion, a second ramp on the first side of the central portion, a third ramp on a second side of the central portion, and a fourth ramp on the second side of the central portion. The first ramp, the second ramp, and the third ramp are longitudinally-staggered. The central portion comprises a hump intermediate the first ramp and the third ramp, and a stabilizer extending from the hump distally beyond the ramps.
