20130233908 | ACTIVE WEDGE AND I-BEAM FOR SURGICAL STAPLER - A surgical stapling device designed and constructed for cutting and stapling tissues in a surgical procedure. The surgical stapling device includes an actuated wedge to deploy staples. The actuated wedge is put into an active state by a first wedge actuation element. In the active state, the actuated wedge is ready to engage and deploy staples in a staple holder. The actuated wedge is put into a neutral state by a second wedge actuation element. In the neutral state, the actuated wedge disengages with the staples and does not deploy the staples. The surgical stapling device includes an I-beam that acts to maintain a clamp gap between the anvil and staple holder of the surgical stapling device to ensure proper stapling of tissue. | 09-12-2013 |
20130289584 | COMPLIANT ANASTOMOSIS SYSTEM UTILIZING SUTURE - An integrated anastomosis tool may include an effector that both makes an opening in the wall of a target vessel and connects a graft vessel to the target vessel. The effector may include a cutter assembly and a connection module that are independently actuatable. The connection between the graft vessel and the target vessel may be compliant, and may be achieved by suturing an end of the graft vessel to the side of the target vessel with the connection module. | 10-31-2013 |
20130306705 | FEEDER BELT FOR TRUE MULTI-FIRE SURGICAL STAPLER - An exemplary surgical apparatus may include a feeder belt configured as a continuous loop; staples fixed to and shearable from the continuous feeder belt; apertures defined in the continuous feeder belt; and a gear positioned at the distal end of the feeder belt within the continuous loop, where the gear engages at least one of the apertures to move the continuous feeder belt around the gear. Another exemplary surgical apparatus may include a feeder belt; a plurality of staples fixed to and shearable from the continuous feeder belt; and a plurality of teeth defined on the continuous feeder belt. Another exemplary surgical apparatus may include a continuous belt assembly that has a flexible rack with two ends, and a feeder belt with two ends, each end of the feeder belt connected to a corresponding end of the flexible rack; and staples fixed to and shearable from the continuous feeder belt. | 11-21-2013 |
20140033674 | METHOD OF MANUFACTURING SURGICAL STAPLES - One exemplary process for manufacturing a surgical apparatus may include providing a flat, generally-planar strip of biocompatible material; cutting the strip to produce a feeder belt with at least one lateral edge, and staples affixed to the feeder belt in proximity to at least one lateral edge, where the staples and feeder belt are substantially aligned along a first plane; and bending at least one staple out of the first plane, while the feeder belt remains in the first plane. Another exemplary process for manufacturing a surgical apparatus may include providing a flat, generally-planar strip of biocompatible material; cutting that strip to produce a feeder belt with edges, and staples affixed to different edges of the feeder belt; and coining at least one staple after the cutting. | 02-06-2014 |
20140135832 | STAPLE TRAP FOR SURGICAL STAPLER - An exemplary staple holder of a surgical stapler may include a cavity defined therein, staples held within that cavity; an upper surface; apertures defined through the upper surface through which staples are deployable, at least one wedge movable within the cavity, and at least one staple trap including a strip and arms extending from and bent relative to the strip, where at least one arm resides in a neutral position directly underneath a corresponding aperture. | 05-15-2014 |
20140175147 | SURGICAL STAPLER WITH REDUCED CLAMP GAP FOR INSERTION - A surgical apparatus may include a staple holder, an anvil connected to and movable relative to the staple holder, and at least one axle extending outward from the anvil; and an overtube slidable relative to the end effector, the overtube including at least one slot defined therein; where each slot receives a corresponding axle. A surgical method for treating tissue of a patient may include providing an end effector that includes a staple holder and an anvil connected to and movable relative to the staple holder, and an overtube slidable relative to said end effector, making an incision in the patient; inserting the end effector and at least part of the overtube through the incision in a first, insertion configuration in which substantially no gap exists between the anvil and staple holder, and moving the overtube relative to the end effector to open the end effector to a second, unclamped position where at least part of the anvil is spaced apart from the staple holder. | 06-26-2014 |
20140175153 | BARBED SURGICAL STAPLE - An exemplary surgical staple may include a base including a first end and a second end; a single tine extending from the second end of the base; and a barb extending from the base at a location between the first end of the base and the second end of the base. An end of such a staple may be frangibly affixed to a feeder belt. Another exemplary surgical apparatus may include at least one staple including a base including a first end and a second end, a first tine extending from the second end of the base, and a second tine extending from the base at a location between the first end of the base and the second end of the base. | 06-26-2014 |
20140332580 | D-SHAPED SURGICAL STAPLES - A surgical apparatus comprises a surgical staple for treating tissues of a patient in a surgical procedure. The surgical staple is deformable from a first configuration (e.g., an undeployed configuration) to a second configuration (e.g., a deployed configuration) in accordance with embodiments of the present invention. The surgical staple includes a first leg and a second leg, wherein said surgical staple substantially resembles a V-shape or a suture needle in the first configuration and substantially forms a D-shape in the second configuration in accordance with embodiments of the present invention. | 11-13-2014 |
