20110079627 | APPLICATOR INSTRUMENTS HAVING CURVED AND ARTICULATING SHAFTS FOR DEPLOYING SURGICAL FASTENERS AND METHODS THEREFOR - An applicator instrument for dispensing surgical fasteners includes a housing and a curved shaft. Surgical fasteners are disposed within the curved shaft for being dispensed from the distal end of the curved shaft. An advancer is disposed inside the curved shaft for shifting the surgical fasteners one position closer to the distal end of the curved shaft each time the advancer moves distally. A firing element is disposed inside the curved shaft and is movable between the proximal and distal ends of the curved shaft for dispensing the surgical fasteners from the distal end of the curved shaft. A staging assembly is adapted to receive a leading one of the surgical fasteners from the advancer as the advancer moves distally to shift the leading surgical fastener into substantial alignment with the firing element when the advancer moves proximally. | 04-07-2011 |
20130218177 | SURGICAL FASTENERS HAVING ARTICULATING JOINTS AND DEFLECTABLE TIPS - A surgical fastener for securing a prosthetic device to tissue includes a first leg having a proximal end, a distal end, a first insertion tip at the distal end, and a first articulating joint that separates said first leg into a proximal segment and a distal segment that is deflectable relative to the proximal segment, and a second leg including a proximal end, a distal end, a second insertion tip at the distal end, and a second articulating joint that separates said second leg into a proximal segment and a distal segment that is deflectable relative to the proximal segment. A bridge connects the proximal ends of the first and second legs for forming a closed end of the surgical fastener. After implantation in tissue, the insertion tips are deflectable away from vessels and nerves to minimize injury to the vessels and nerves, and to minimize patient discomfort and pain. | 08-22-2013 |
20130245642 | CLAMPING DEVICES FOR DISPENSING SURGICAL FASTENERS INTO SOFT MEDIA - A clamping device for dispensing surgical fasteners includes a lower arm having a proximal end, a distal end, and a longitudinal axis extending between the proximal and distal ends, and an upper arm pivotally connected with the lower arm. An actuator is coupled with the upper and lower arms for moving the distal ends of the arms toward one another for closing the clamping device. A surgical fastener dispenser is secured to the distal end of the lower arm. The dispenser includes a cartridge body having a top surface with a surgical fastener dispenser opening. A pad is pivotally connected to the distal end of the upper arm. When the clamping device is closed, a bottom surface of the pad applies a clamping force upon the top surface of the cartridge body for dispensing one of the surgical fasteners at an angle that is perpendicular to the longitudinal axis. | 09-19-2013 |
20130304091 | APPLICATOR INSTRUMENTS HAVING DISTAL END CAPS FOR FACILITATING THE ACCURATE PLACEMENT OF SURGICAL FASTENERS DURING OPEN REPAIR PROCEDURES - An applicator instrument for dispensing surgical fasteners includes a housing, a firing system disposed in the housing, an actuator coupled with the housing for actuating the firing system, an elongated shaft extending from the housing, the elongated shaft having an outer diameter, and a cap secured to the distal end of the elongated shaft, whereby the cap has a lower distal edge that extends laterally beyond the outer diameter of the elongated shaft. The lower distal edge of the cap has a length that is greater than the outer diameter of the elongated shaft. The cap has a distal end face that slopes upwardly and proximally from the lower distal edge, and the cap has a surgical fastener delivery window formed in the distal end face for dispensing surgical fasteners. The delivery window has a lower end that is spaced from the lower distal edge. | 11-14-2013 |
20130304092 | APPLICATOR INSTRUMENTS FOR DISPENSING SURGICAL FASTENERS DURING OPEN REPAIR PROCEDURES - An applicator instrument for dispensing surgical fasteners includes a housing, a firing system disposed in the housing and being moveable in distal and proximal directions along a first axis, and an elongated shaft extending from the housing, the elongated shaft having a proximal section and a distal section that is oriented at an angle relative to the proximal section. A plurality of surgical fasteners are disposed in the elongated shaft. The applicator instrument has a handle that extends upwardly from the housing along a second axis that defines an acute angle with the first axis. A trigger is mounted on the handle, and a linkage couples the trigger with the handle and the firing system. When the trigger is squeezed, the linkage guides the trigger along a linear path of movement relative to the handle. | 11-14-2013 |
20140379001 | METHODS OF USING APPLICATOR INSTRUMENTS FOR SECURING PROSTHETIC DEVICES TO TISSUE - A method of securing a prosthetic device to tissue includes providing an applicator instrument including a housing, a shaft, surgical fasteners, a firing rod for dispensing the surgical fasteners from the shaft, a trigger, and an energy storing element. The method includes positioning a prosthetic device over tissue, juxtaposing a distal end of the shaft with the prosthetic device, and compressing the trigger for piloting the firing rod toward the distal end of the elongated shaft at a first rate of speed. The method includes preventing the firing rod from moving distally while building up energy in the energy storing element, and further compressing the trigger for releasing the firing rod for distal movement and transferring the built up energy for moving the firing rod toward the distal end of the elongated shaft at a second rate of speed that is greater than the first rate of speed. | 12-25-2014 |
20150080919 | SURGICAL FASTENERS FOR SECURING PROSTHETIC DEVICES TO TISSUE - A surgical fastener includes a first leg having a distal end, a proximal end, and a first insertion tip at the distal end of the first leg, the first insertion tip having a first distal piercing point, and a second leg having a distal end, a proximal end, and a second insertion tip at the distal end of the second leg, the second insertion tip having a second distal piercing point. A bridge connects the first and second legs. The first and second distal piercing points are located outside the respective first and second legs. The first and second legs extend along respective longitudinal axes, and the first and second insertion tips are asymmetrical and skewed outwardly relative to said respective longitudinal axes of the first and second legs. | 03-19-2015 |
20150351753 | Methods and Devices for Reinforcing a Staple Line - Adjunct material and methods of using adjunct material to reinforce a staple line are provided herein. In general, adjunct material can be used to maintain a seal in tissue and prevent stapled tissue from tearing. This adjunct material can be coupled to a jaw of a surgical stapler, and can be deployed into tissue along with the staples. In some embodiments, the adjunct material can be sized and shaped so that a portion of the material extends laterally outside of the staple line and distributes strain to tissue outside of the staple line. In certain aspects, sealant can be applied to the staple line and to the adjunct material in various ways to further seal the tissue and/or prevent leaks from forming in the tissue. | 12-10-2015 |
20150351760 | DEVICES AND METHODS FOR SEALING STAPLES IN TISSUE - Devices and methods for applying sealants to surgical instruments are described herein. In one embodiment, a surgical device is described that can include at least one nozzle formed at a proximal end of the device that is configured to receive a sealant, as well as an applicator formed at a distal end of the device that is configured to deliver the sealant received by the at least one nozzle. The applicator can be configured to interface with at least one of a first and second jaw of a surgical stapler such that the sealant delivered from the applicator can be deposited into a plurality of openings formed in the surgical stapler. | 12-10-2015 |
