  • Patent number: 10426567
    Abstract: The invention provides a retractor having a lighting module which is removeably attached to a paddle of the retractor. The retractor is able to provide improved illumination of a workspace within the body by attaching the light source directly to the paddle. As the light source is removeable from the paddle, it enables the light source to be removed after use and discarded while the retractor can be re-used. Furthermore, as the light source is removeably attached at a distal end of the paddle, the illumination is provided closest to the workspace, regardless of the length of the paddle.

  • Patent number: 8979750
    Abstract: Embodiments described herein include devices, systems, and methods for reducing the distance between two locations in tissue. In one embodiment, an anchor may reside within the right ventricle in engagement with the septum. A tension member may extend from that anchor through the septum and an exterior wall of the left ventricle to a second anchor disposed along a surface of the heart. Perforating the exterior wall and the septum from an epicardial approach can provide control over the reshaping of the ventricular chamber. Guiding deployment of the implant from along the epicardial access path and another access path into and through the right ventricle provides control over the movement of the anchor within the ventricle. The joined epicardial pathway and right atrial pathway allows the tension member to be advanced into the heart through the right atrium and pulled into engagement along the epicardial access path.

    Abstract: Methods and devices are provided for retracting tissue. In one exemplary embodiment, a retractor is provided that includes a base and a plurality of blades configured to removably and replaceably mate to the base. One or more of the plurality of blades can be configured to mate to the base in one of a plurality of available positions. In use, one or more adjustment mechanisms can be actuated to move one or more of the blades, thereby forming a pathway through tissue. The retractor can be formed from one or more radiolucent materials.

  • Publication number: 20130204090
    Abstract: A method of performing an operation, e.g. a spinal operation, on a patient using a retractor comprising a pair of blade assemblies which are adapted to open about a set of axes that are not parallel to a third spatial axis, and further comprising a pair of arms, which are adapted to move the pair of blade assemblies apart from one another in the third spatial axis. In the method, the blade assemblies are closed to assume a low profile, inserted into a relatively small incision, and stretched apart from each other, thereby stretching the skin about the incision to form an aperture longer than the incision. The blade assemblies are then opened by rotating the blades about the set of axes, stretching the skin around the incision in a second direction that is substantially perpendicular to the first direction (i.e. the direction of the incision).

  • Patent number: 8460185
    Abstract: A surgical retractor assembly that utilizes a tubular shaft and a connection nub. A pivot joint connects one end of the tubular shaft to the connection nub. The pivot joint enables the connection nub to move relative the tubular shaft along a path that is coplanar to the axis of the tubular shaft. Together, the tubular shaft and the connection nub create an elongated element that can be introduced into a small incision. A retractor blade is provided. A bearing joint extends from the retractor blade. The retractor blade and bearing joint are introduced into a surgical site independent of the elongated element. Within the surgical site, the connection nub interconnects with the bearing joint, therein joining the retractor blade to the tubular shaft and a handle.

  • Publication number: 20130085341
    Abstract: Methods and devices are provided for manipulating tissue in a body cavity, i.e., in vivo. In general, the methods and devices allow an end effector to engage tissue, be detached from a shaft used to control the end effector to engage the tissue, and then be moved to another location in the body cavity by a separate component, such as an external control unit. In some embodiments the end effector can include one or more deployable hooks that allow the end effector to remain at a surgical site independent of any shafts or external control units. Still further, in other embodiments the end effector can include a transverse bore to allow a second shaft to connect to the end effector to manipulate the tissue. Additional exemplary devices, kits, and methods related to manipulating tissue in vivo are also provided.

  • Patent number: 8388525
    Abstract: A retractor includes a retractor support and an elongated retractor blade. The retractor blade has a first, closed position in which ends of the blade are positioned proximal to the support and a second, open position in which ends of the blade are positioned distal to the support. The retractor support has structure for engaging the retractor blade. A handle extends from the retractor support. A method of retracting tissue is also disclosed.

  • Patent number: 8360971
    Abstract: Surgical retractor systems including removable angling devices and methods of use are provided. A surgical retractor system can include a head with an opening, a blade including a nipple, and an angling device including a handle. The nipple can include a first recess that runs circumferentially around an exterior surface of the nipple and terminates at a flange. The opening can be configured to receive the nipple. The nipple can be longer than the opening such that the flange and at least a portion of the recess extend beyond an end of the opening when the blade is attached to the head. The angling device can be configured to receive the flange such that the angling device can be removably attached to the flange. The angling device can be used to manipulate the position of the blade when the angling device is attached to the flange.

  • Patent number: 8357087
    Abstract: A grasper for a surgical retractor is provided. The grasper has a grasper body, a push-button activator and a holder to releasably retain a connector head of, for example, a retractor blade. The holder is configured to move from a first position, located at least partially in the opening to provide for selectively retaining the connector head in the opening, to a second position wherein the connector head may be removed. The push-button activator is operably connected to the holder to move the holder from the first position to the second position. In one embodiment the holder is gear driven by the activator.

  • Patent number: 8323185
    Abstract: A surgical access device assembly that allows access to a pathology being treated while significantly reducing the risk of damaging anatomical structures proximate the pathology. The access device assembly includes a base portion having a central bore extending therethrough, and retractor blades pivotably mounted to the base portion. An insertion handle is coupled to the base portion to thread the retractor blades into the patient. The insertion handle is removed from the base portion, and a core hollow screw is threaded into the base portion to separate the retractor blades to gain access to the pathology through the hollow screw.

  • Publication number: 20120245431
    Abstract: A retractor includes a first arm, a second arm, and a translating member. The first arm comprises a proximal portion configured to retain a first retractor member and a distal portion configured to rotate relative to the proximal portion about a first axis. The second arm is configured to retain a second retractor member, such that rotation of the distal portion about the first axis causes the first retractor member to pivot toward or away from the second retractor member when the first retractor member and the second retractor member are coupled to the first arm and the second arm, respectively. The translating member is coupled between the proximal portion and the distal portion, and is configured to receive a drive force that causes the translating member to bias the distal portion to pivot relative to the proximal portion about the first axis.
