Abstract: A surgical device includes a motor and a reload having a plurality of staples. The surgical device also includes an anvil assembly movable relative to the reload by the motor to clamp tissue therebetween. The device further includes a force sensor configured to measure force imparted on the anvil assembly. The device additionally includes a controller configured to compare the measured force to a target force, determine a distance at which the measured force matches the target force, and output the distance and the target force.

Abstract: A surgical device including a handle assembly, an elongated portion, and outer band assembly, and inner band assembly, a trocar assembly, and a seal assembly is disclosed. At least a portion of the outer band assembly is disposed radially within the outer sleeve. At least a portion of the trocar assembly is disposed radially within the inner band assembly. The seal assembly includes a first annular seal and a second annular seal. The first annular seal is disposed radially inward of the outer sleeve and radially outward of the outer band assembly. The second annular seal is disposed radially inward of the outer band assembly and radially outward of the inner band assembly.

Abstract: A trans-anastomotic insertion device includes a body having a distal portion, a proximal portion, and a central portion. The distal portion has a blunt distal end, a width that decreases from its distal end to its proximal end, and longitudinal ribs that provide rigidity to the distal portion. The central portion has a circular configuration and includes a proximally facing surface that includes protrusions that are positioned to be received within staple pockets of a reload assembly of a stapling device. The proximal portion includes a central post that includes splines that are received between splines on a shell housing of a stapling device. The configuration of the insertion device provides added strength to the insertion device to resist high torsional forces that may be applied to the insertion device during insertion of a surgical device through an incision into a body cavity.

Abstract: A surgical occluding device includes a body portion configured to radially surround a tissue lumen. The body portion includes a plurality of segments and a plurality of folds. Each fold of the plurality of folds is defined between adjacent segments of the plurality of segments. Half of the folds of the plurality of folds define acute angles, and half of the folds of the plurality of folds define obtuse angles. The body portion is movable from a first orientation where the acute angle defines a first acute angle, to a second orientation where the acute angle defines a second, smaller acute angle.

Abstract: A force sensor includes a substrate, sensing elements, a flex cable, and a seal assembly. The substrate has proximal and distal surfaces, and a cavity defined therein. The sensing elements are disposed within the cavity of the substrate and the pin block assembly is electrically coupled to the sensing elements. The seal assembly includes at least one gasket, a retainer plate, and a seal restraint. The seal assembly is held under compressive load to seal the cavity of the substrate and protect the sensing element disposed therein.

Abstract: A buttressed anvil assembly is provided for use with a surgical stapling instrument. The buttressed anvil assembly generally includes an anvil member having a strip of buttress material attached thereto by a pair of sutures. A tensioning mechanism is provided to secure or tension the buttress material to the anvil member prior to use and allow for release of the buttress material after stapling of tissue. The tensioning mechanism includes a cinch track engageable with one of the pair of sutures.

Abstract: An anvil assembly includes a retaining member having a body portion and a frangible portion connected to the body portion, where the frangible portion is positioned to engage a backup member and separates from the body portion during movement of the backup member from a first, proximal position to a second, distal position. The retaining member keeps the backup plate in the proximal position prior to firing of the stapling assembly, and upon separation of the frangible portion allows the backup plate to move to the distal position during firing of the stapling assembly. Proximal force on the backup plate after firing of the stapling assembly is avoided, thereby helping to ensure titling of the anvil assembly.
