This assembly includes a tubular body and a cap attached to the tubular body to define a chamber for an active material. The tubular body includes a transverse wall and a peripheral wall and the cap includes a base wall and a side wall. The chamber is delimited by a part of the tubular body including the transverse wall and is closed by the cap. The side wall of the cap on its periphery includes a plurality of longitudinal features in relief which cooperate by mutual engagement with complementary longitudinal features in relief provided on the peripheral wall of the tubular body substantially parallel to its longitudinal axis (X.sub.2).

Stapling devices and staple cartridges are disclosed. A stapling device can include a jaw configured to sequentially receive a plurality of dissimilar staple cartridges having different bioabsorbable components. An adjustment module can implement a firing control algorithm based on which dissimilar staple cartridge is received in the jaw. A staple cartridge can include staples comprised of a bioabsorbable metal alloy and configured to degrade at a staple degradation rate over an expected staple life in the patient. A staple cartridge can also include an implantable layer comprised of a bioabsorbable polymer and configured to degrade at a layer degradation rate over an expected layer life in the patient. The staple degradation rate and the implantable degradation rate can be different. The implantable layer can mechanically support at least a portion of a staple for a time in the expected staple life.

A method of pairing bioabsorbable staples in a staple cartridge with the tissue being treated such that the staples are structurally sufficient during the healing window of the tissue but completely bioabsorb shortly thereafter.

A surgical instrument comprising a handle, an elongate shaft, an end effector, an articulation joint, an articulation knob, an articulation member, and an articulation lock is disclosed. The end effector is rotatably coupled to the elongate shaft by the articulation joint. The articulation knob is rotatable between an un-rotated position and rotated positions. The articulation lock comprises a lock member configured to move between a locked position where the lock member is engaged with a detent of the end effector and an unlocked position where the lock member is disengaged from the end effector. The lock member is movable between the locked position and the unlocked position by the articulation knob. The articulation member is moved from a proximal position toward a distal position to articulate the end effector when the articulation knob is moved from the un-rotated position toward a rotated position.

A surgical staple comprising a substrate and one or more coatings which slows the bioabsorption of the substrate. The coating can be selected so as to affect the environment surrounding the staple once the staple is implanted in the patient. The effect on the environment can cause the bioabsorption to occur within a desired time frame.

A staple cartridge comprising a cartridge body comprising a longitudinal slot, a deck surface, and a plurality of staple cavities defined in the cartridge body is disclosed. The cartridge body further comprises a plurality of projections extending from the deck surface. A surface of each projection is flush with one of a proximal end wall and a distal end wall of each staple cavity. The staple cartridge further comprises staples removably stored in the staple cavities.

A method for assembling a physiological signal monitoring apparatus on a body surface of a living body is provided, wherein the physiological signal monitoring apparatus is used to measure a physiological signal and includes a sensor module and a transmitter. The method comprises steps of: (a) detaching the bottom cover from the housing to expose the sticker from the bottom opening; (b) while holding the housing, causing the adhesive pad to be attached to the body surface; (c) applying a pressing force on the housing to cause the sensor module to be detached from the implantation module and the signal sensing end to be implanted under the body surface; (d) removing the implanting device while leaving the sensor module on the body surface; and (e) placing the transmitter on the base so that the signal output end is electrically connected to the port.

A surgical instrument comprising an elongate channel, an anvil, a staple cartridge, a firing member, and a lockout key is disclosed. The elongate channel comprises a blocking member. The staple cartridge comprises staples and a sled movable from a proximal end position to an intermediate position and then to a distal position during a staple firing stroke. The firing member is movable distally to advance the sled through the staple cartridge during the staple firing stroke to eject the staples from the staple cartridge. The firing member comprises a cutting edge. The lockout key is movably mounted to the sled. The lockout key is movable between an unactuated position and an actuated position during the staple firing stroke. The lockout key lifts the firing member over the blocking member when the lockout key is moved from the unactuated position toward the actuated position.

A packaging, in particular sterile packaging, for a medical product, includes a receiving space for the medical product. A portion of the packaging facing the receiving space is made at least in part, preferably entirely, of a resorbable material.

An implantation device for prompt subcutaneous implantation of a sensor to measure a physiological signal of an analyte in a biofluid of a living body is disclosed. The implantation device includes a housing, an implantation module, a detachable module and a bottom cover. The housing has a bottom opening. The implantation module includes an implanting device and a needle extracting device. The detachable module includes the sensor detachably engaged with the implantation module; and a base configured to mount the sensor thereon. The bottom cover is detachably coupled to the bottom opening so that the housing and the bottom cover together form an accommodating space. The implantation module and the detachable module are accommodated in the accommodating space. The bottom cover has an operating portion configured to bear a force, and a supporting portion is formed on the opposite end of the operating portion.
