Publication number: 20220240923Abstract: Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.Type: ApplicationFiled: February 24, 2022Publication date: August 4, 2022Inventors: Christopher J. Hess, Frederick E. Shelton, IV, Jerome R. Morgan, Ryan A. Bledsoe, Douglas E. Withers, Craig T. Gates

Patent number: 10912543Abstract: Devices and methods for delivering end effectors through surgical trocars are described herein. In one embodiment, a surgical end effector loading device is provided that includes a housing having a distal-facing first portion configured to couple with a proximal end of a surgical trocar, and an elongate second portion protruding distally from the first portion. The second portion can include a lumen formed therein and can be configured to extend into a working channel of the surgical trocar when the housing is coupled thereto. The device can also include at least one mating element coupled to the housing and configured to interface with a complementary mating element of the surgical trocar to restrict movement of the housing relative to the trocar, as well as an end effector retainer coupled to the housing and configured to selectively couple a surgical end effector to the housing.Type: GrantFiled: November 3, 2015Date of Patent: February 9, 2021Assignee: Ethicon LLCInventors: Christopher J. Hess, Frederick E. Shelton, IV, Ryan A. Bledsoe, Jeffrey L. Savage, Craig T. Gates, Douglas E. Withers

Patent number: 10675009Abstract: Devices and methods for organizing a plurality of end effectors and selectively delivering them through surgical trocars are described herein. In one embodiment, a surgical end effector loading device is provided that includes at least one mating element to interface with a surgical trocar, a deployment lumen positioned to align with a working channel of a surgical trocar, an end effector repository having a plurality of end effector lumens formed therein to receive end effectors, the repository being configured to selectively align any of the plurality of end effector lumens with the deployment lumen, and an advancer coupled to the repository and configured to advance an end effector from the repository through the deployment lumen.Type: GrantFiled: November 3, 2015Date of Patent: June 9, 2020Assignee: Ethicon LLCInventors: Christopher J. Hess, Frederick E. Shelton, IV, Ryan A. Bledsoe, Jeffrey L. Savage, Craig T. Gates, Douglas E. Withers

Patent number: 10342520Abstract: Surgical devices and methods are described. The loading devices can include an elongate shaft extending distally from a housing and a hinge can be disposed between the elongate shaft and an articulating distal portion. The articulating distal portion can hold an end effector to be loaded onto a surgical device. The loading device can have features for stabilizing and holding the distal portion at a particular angular position relative to the elongate shaft, such as washers having protrusions that seat in corresponding recesses formed in the hinge. During articulation of the distal portion, an articulation rack can be advanced which can deform the protrusions on the washers. The washers can rotate and seat in the recesses at the next angular position and change the degree of articulation. The deformable washer and corresponding recesses can apply a biasing force that holds the articulating distal portion in a desired angled position.Type: GrantFiled: August 26, 2015Date of Patent: July 9, 2019Assignee: Ethicon LLCInventors: Christopher J. Hess, Frederick E. Shelton, IV, Ryan A. Bledsoe, Monica L. Zeckel, Jeffrey L. Savage
