Tissue thickness compensator comprising a plurality of layers
A tissue thickness compensator comprising a first compensation layer, a second compensation layer, and a pocket situated between the compensation layers can be positioned in the end effector of a surgical instrument. A fastener cartridge positioned in the end effector can comprise a fastener moveable between an initial position and a fired position. When the fastener is moved from the initial position to the fired position, the fastener can move through the pocket and can compress a portion of the tissue thickness compensator. A support can be positioned between the first and second compensation layers. When the fastener compresses the tissue thickness compensator, at least one of the support, first compensation layer and second compensation layer can be deformed. The tissue thickness compensator can also comprise a tab and/or a limiting plate to control deformation of the compensation layers and/or the support.
Firing lever assembly for linear surgical stapler
A handle assembly includes two arms and a latching lever. An end effector includes two jaws. A firing assembly includes an actuating beam, a proximal body, and two levers. The actuating beam is slidable relative to the handle assembly and the end effector. The proximal body is coupled to the actuating beam and is housed within either the first arm or the second arm. The first lever is configured to move between a first laterally extending position and a first non-obtrusive position. The first lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the first laterally extending position. The second lever is configured to move between a second laterally extending position and a second non-obtrusive position. The second lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the second laterally extending position.
Catheter with sealed hydratable hemostatic occlusion element
Apparatus for sealing a vascular wall penetration disposed at the end of the tissue tract comprises a shaft, an optional occlusion element, a hydratable hemostatic implant, and a protective sleeve. The apparatus is deployed through the tissue tract with the occlusion element optionally occluding the vascular wall penetration and inhibiting backbleeding therethrough. The hydratable hemostatic implant, which will typically be a biodegradable polymer such as collagen carrying an anti-proliferative agent or coagulation promoter, will then be deployed from the sealing apparatus by retracting the protective sleeve and left in place to enhance closure of the vascular wall penetration with minimum scarring. The hydratable implant will be protected from premature hydration and swelling by a soluble plug covering the implant's distal end prior to sleeve retraction.
Medical device for repairing soft tissue and method of using same
A medical device for repairing soft tissue is disclosed. The medical device includes a cannulated probe positionable a tear in the soft tissue and a stop. The cannulated probe has an inlet about a proximal end and at least one outlet about a distal end with a lumen therethrough. The inlet is operatively connectable to an adhesive source to receive the adhesive therein. The outlet(s) is/are positionable about the tear to emit the adhesive about the tear. The stop is disposable about a periphery of the probe a distance from the inlet, and is positionable adjacent a surface of the soft tissue to terminate advancement of the cannulated probe into the soft tissue whereby a delivery portion of the cannulated probe is positionable about the soft tissue to deliver the adhesive about the tear.
Surgical adjunct retaining mechanisms
An adjunct can be releasably retained on an end effector of a surgical tool, such as a surgical stapler, using a plurality of retaining elements. The retaining elements can be configured to retain the adjunct to the end effector with a mechanical force until a force is applied to the adjunct that overcomes the mechanical force, thereby allowing release of the adjunct from the end effector and into a patient's body.
Mesh assembly and manufacturing method thereof
Provided is a mesh assembly inserted to a soft tissue or a human tissue for lifting the soft tissue, the mesh assembly including: a mesh member inserted into the soft tissue or human tissue and supporting the tissue; a fixed member provided at the mesh member and adopted to increase a coupling force in the soft tissue or the body; and a hook member formed on an upper surface or a lower surface or both of the fixed member to protrude in a diagonal direction, so that fixation of the soft tissue or human tissue can be firmly conducted, thereby allowing the soft tissue and the like to be fixed at a normal position without undergoing an influence by shaking or an external shock.
Surgical stapling device for performing circular anastomosis and surgical staples for use therewith
The present disclosure relates to an anvil assembly, an end effector and/or a surgical stapler suitable for performing curved or circular anastomosis and/or treatment to internal walls of hollow tissue organs wherein the anvil assembly includes an anvil center rod having a proximal end and a distal end, the center rod defining a central longitudinal axis; and an anvil head secured to the distal end of the anvil center rod. The anvil head includes an anvil plate defining a tissue contact surface; and a plurality of staple forming pockets formed in the tissue contact surface of the anvil plate, wherein each of the plurality of staple pockets defines an arcuate longitudinal axis.
Bioabsorbable medical devices
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a plurality of absorbable filaments arranged in a support structure and configured degrade within a defined time period and a membrane arranged about the plurality of absorbable filaments and configured to contain fragments of the plurality of absorbable filaments in response to a fracture or degradation of a filament.
Tissue stop for surgical instrument
A surgical instrument for surgically joining a tissue includes a handle assembly, an elongate portion extending distally from the handle assembly, a pair of opposed jaw members, and a tissue stop. The tissue stop is mechanically engaged with a first jaw member and is configured to retain the tissue between the jaw members. The tissue stop is movable between a first position, where a stopping portion of the tissue stop is disposed between a tissue-contacting surface of the first jaw member and a tissue-contacting surface of the second jaw member, and a second position, where the stopping portion is between the tissue-contacting surface of the first jaw member and a lower surface of the first jaw member. A portion of the tissue stop is made of stamped metal section and a portion of the tissue stop is made of an overmolded plastic section.
End effector having extension features for mating with adjuncts
An end effector for a surgical instrument is provided that has a first jaw, such as a cartridge body, having on a tissue-contacting surface thereof a plurality of staple cavities configured to seat staples therein, and a second jaw, such as an anvil, with a plurality of staple forming cavities formed on a tissue-contacting surface thereof. The first jaw has a generally rectangular nominal perimeter defining a regular perimeter around outer rows of the plurality of staple cavities. At least one of the first and second jaws has extension elements extending beyond the nominal perimeter of that jaw such that each of the extension elements has at least one attachment feature formed thereon. An adjunct material having a shape complementary to a shape of the jaw is configured to releasably mate with the attachment features formed on the jaw, via corresponding adjunct's mating features.
