  • Patent number: 9226760
    Abstract: Methods and devices are provided for performing minimally invasive surgical procedures. In one embodiment, a surgical device is provided that includes an elongate shaft having an end effector at a distal end thereof. The end effector can be configured to be movable between a first configuration in which the end effector is longitudinally aligned with or linear relative to the shaft and a second configuration in which the end effector is articulated at an angle beyond 45 degrees relative to the shaft. With the end effector in the first configuration or in the second configuration, the device can be configured to allow selective actuation of the end effector.

  • Patent number: 9211140
    Abstract: In one form, a system for use in percutaneous surgical procedures includes a cannula having an elongate body extending along a longitudinal axis between a proximal end and a distal end and including a working channel dynamically expandable from a first, unexpanded configuration. The system also includes a device that is positionable in and engageable with the working channel to expand the working channel from the first configuration as the device is moved through the working channel. In response to disengagement of the device with the working channel, the working channel returns to the first, unexpanded configuration. In one aspect of this form, the device includes an interbody spinal implant that is deliverable to a surgical site through the working channel of the cannula. In another form, a method for performing a percutaneous surgical procedure is provided. However, different forms and applications are envisioned.

  • Patent number: 9033873
    Abstract: A surgical access port is provided for insertion through an incision formed in a body wall of a patient. The surgical access port generally includes a sleeve assembly having a folding assembly provided at a proximal end of the sleeve assembly. The sleeve assembly includes a flexible sleeve and a flexible distal ring provided at a distal end of the flexible sleeve. A proximal end of the sleeve assembly includes a pocket formed in the sleeve material. The folding assembly is located in the pocket and generally includes a proximal ring and one or more ring knobs rotatably mounted on the proximal ring. Locking structure, in the form of a ratchet and pawl mechanism, may be provided to secure the ring knobs in position relative to the proximal ring.

  • Patent number: 9028403
    Abstract: A surgical access device for insertion into an opening in tissue includes an adjustable member at a proximal end which is transitionable between an un-deployed configuration where the adjustable member is rolled up proximally and a deployed configuration where the adjustable member is unrolled distally to allow for the use of the surgical access device in an opening having a larger size than the surgical access device. The surgical access device includes an elongate member which is adapted for insertion into an opening in tissue and including a lumen extending therethrough for the reception of a surgical instrument. An adjustable member extends from a proximal portion of the elongate member and is variable between the un-deployed configuration and the deployed configuration where the adjustable member extends distally from the proximal portion of the elongate member when in the deployed configuration to at least partially surround the elongate member.

  • Patent number: 9028402
    Abstract: A surgical access apparatus includes a liner base and an access housing for positioning outside the body. The liner base includes an inner member adapted for insertion through an opening within body tissue for positioning within the body; a sleeve member connected to the inner member and dimensioned to extend from the inner member through the opening within the body tissue, and a plurality of tensioning elements connected to the inner member and associated with the sleeve member to impart a tensioning effect on the sleeve member. The access housing includes a first element and a second element. The second element is operatively connected to the tensioning elements and adapted for rotational movement relative to the first member to cause the tensioning elements to displace the inner member toward the access housing and to cause the sleeve member to engage and retract tissue defining the opening within the body.

  • Patent number: 9022928
    Abstract: A surgical access device is disclosed herein. The surgical access device includes a housing adapted for insertion into an incision in tissue and at least one inflatable portion disposed on the housing. The housing defines a proximal end and a distal end and has a lumen extending therethrough for the reception of a surgical access portal. The at least one inflatable portion has a deflated state and an inflated state and the housing is insertable into the incision in tissue when the at least one inflatable portion is in the deflated state. The housing is adapted to form a substantially fluid tight seal with the incision in tissue and with a surgical access portal inserted therethrough when the at least one inflatable portion is in the inflated state.

  • Publication number: 20150119647
    Abstract: In one embodiment, the wound protector has an annularly collapsible proximal ring and a flexible sleeve extends between the proximal ring and distal ring. After positioning of the distal ring in a wound, the proximal ring is expanded to draw the sleeve taut between the rings 11, 12 and is drawn tight against the wound. In a second embodiment, the wound protector has a flexible sleeve secured between a distal ring and proximal ring of fixed diameters. In addition, an expansion member is disposed within a loop of the flexible sleeve about the proximal ring. After positioning of the distal ring in a wound, movement of the expansion member into an extended diametric state expands the loop in the sleeve diametrically while drawing the rings towards each other.

  • Patent number: 9017254
    Abstract: The application relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient's abdomen is reduced.

  • Patent number: 9017253
    Abstract: A device including a hollow pipe with a variable diameter is used for medical procedures. Means are provided for reducing the diameter either internally or externally so that the pipe can be inserted into a patient's body through an incision or an opening until the distal end of the pipe reaches a desired position. Thereafter, the diameter of the pipe is increased to allow various surgical devices to be introduced through the pipe.
