Shape memory implants and a method and apparatus for the loading and implanting thereof
An orthopedic fixation system includes an implant and an implant insertion device. The implant transitions between a natural shape and an insertion shape. The implant includes a bridge defining a slot with a first end and a second end and first and second anchoring members extending from the bridge. The implant insertion device moves between a loaded position and an unloaded position. The implant insertion device in its loaded position inserts through the slot of the bridge and engages the bridge at the first and second ends of the slot such that the implant insertion device constrains the implant in its insertion shape. The implant insertion device in its unloaded position releases the implant.
MEDICAL DEVICE FOR JOINING MATERIALS
A medical device for joining materials is provided. The device comprises a piercing element configured to penetrate materials to be joined. The piercing element is sufficiently sharp to penetrate materials to be joined and comprises a hollow interior along at least a portion of its length configured to distal advancement of a fastener therethrough; and an open tip through which the fastener can be pushed. The device can be used for fastening materials including tissue, synthetic mesh, and biologic mesh (e.g., ADM).
Multi-fire lead screw stapling device
A surgical stapling device comprises a housing and a plurality of cartridges that are coupled together to form a barrel that is rotatably supported within the housing. Each of the cartridges defines a plurality of staple pockets that support a plurality of staples. An anvil is pivotally coupled to the housing and is movable in relation to the barrel between an open position and a clamped position. A drive shaft extends through the housing and through the barrel and a pusher operatively connected to the drive shaft. The pusher is configured to translate through the barrel to eject the staples from the plurality of cartridges in response to actuation of the drive shaft. The barrel is positioned within the housing to align a first one of the plurality of cartridges with the anvil to eject the staples from the first cartridge upon movement of the pusher within the barrel through a first firing stroke and subsequently rotatable within the housing to align a second one of the plurality of cartridges with the anvil to eject the staples from the second cartridge upon movement of the pusher within the barrel through a second firing stroke.
Surgical end effector assembly including a connector strip interconnecting a plurality of staples
A surgical staple cartridge is disclosed comprising a plurality of staples removably stored within the surgical staple cartridge. The staples comprise staple legs which extend from a staple base portion. The staple legs comprise staple tips configured to pierce tissue and contact a corresponding forming pocket of an anvil of surgical stapling instrument. The staples further comprise zones having different hardnesses.
Method for producing a surgical instrument comprising a smart electrical system
A method for producing a surgical instrument is disclosed. The method comprises obtaining a handle, wherein the handle comprises a distal end comprising a shaft interface surface and a first set of magnetic elements. The method further comprises obtaining a shaft, wherein the shaft comprises a proximal end comprising a handle interface surface, a second set of magnetic elements, and a third set of magnetic elements. The method further comprises attaching the shaft to the handle, wherein the shaft interface surface is configured to engage the shaft at the handle interface surface, wherein an attractive magnetic force is configured to pull the handle towards the shaft when the first set of magnetic elements interact with the second magnetic elements, and wherein a repulsive magnetic force is configured to repel the handle from the shaft when the first set of magnetic elements interacts with the third set of magnetic elements.
Knitted tissue scaffolds
Staple cartridge assemblies for use with surgical stapling instruments and methods for manufacturing the same are provided. Scaffolds for use with a surgical staple cartridge and methods for manufacturing the same are also provided.
DISSIMILAR STAPLE CARTRIDGES WITH DIFFERENT BIOABSORBABLE COMPONENTS
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.
METHOD FOR DELIVERING A STAPLE IN SITU PAIRED TO THE IN SITU ENVIRONMENT
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.
Clip applier and methods of use
A system having an elongate assembly, an expandable assembly having a fixed end region and a movable end region, the expandable assembly selectively transitioning between an expanded state and an unexpanded state with movement of the movable end region towards the fixed end region, and an advancement aid extending distally from the expandable assembly.
Staple feeding and forming apparatus
Disclosed is a surgical stapling apparatus and method of use that includes a cartridge assembly which is capable of being reloaded during a surgical procedure without being removed from the surgical site. This allows a surgeon to continue a surgical operation without withdrawing or removing the surgical stapler for reloading and thus reduces the length of the surgery while allowing the physician to concentrate solely on the surgical procedure rather than dividing attention between the surgical procedure and reloading of the surgical stapler. The surgical stapling apparatus includes an elongate member having a plurality of fasteners arranged in a plurality of longitudinally extending rows which is longitudinally translatable through the cartridge to position the plurality of fasteners relative to a plurality of retention slots extending through an upper surface of the cartridge.
