An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

The present invention discloses a rongeur type bone and cartilage removal device incorporating first and second pivotally secured handles, the first handle terminating at a forward end in a first jaw exhibiting a plurality of extending teeth, with second handle terminating in a second jaw opposing the first jaw and exhibiting a continuous blade edge against which the teeth seats during pivotal motion of the jaws.

A uterine manipulator can include a shaft including a first end, a second end, and a channel along an axis of the shaft, a handle coupled to the first end of the shaft, and a triangular balloon coupled to the second end of the shaft. The triangular balloon can be configured to inflate upon insertion into a vagina via a fluid injected into the channel of the shaft.

A medical device may include an inflatable balloon secured to a distal region of a catheter shaft. A blade assembly may extend over and be secured to the inflatable balloon. The blade assembly may include a plurality of blades and at least two rings that are adapted to secure each of the plurality of blades. Each of the rings include an inner surface adapted to be secured to the inflatable balloon and an outer surface. A number of living hinges are formed within the inner surface and the outer surface that cooperate to allow the blade assembly to move between an expanded configuration and a collapsed configuration.

A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.

A device for manipulating tissue at a vessel includes an elongated member having a proximal end and a distal end, a guide member at the distal end of the elongated member, the guide member having a blunt distal tip for engagement against an interior wall of the vessel, and a tissue cutting device at the distal end of the elongated member, wherein the tissue cutting device has a sharp tip that is proximal to the blunt distal tip of the guide member.

An exemplary surgical device includes an element positionable within a shaft having a lumen defined therethrough with the element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen. The element forming a closed loop which is positioned around the lens while the lens is within a capsular bag. The closed loop is reduced in size to form a cut in the lens.

A method of performing an orthopedic procedure in the sacroiliac region. At least one aperture is formed that at least partially extends through at least one of an ilium and a sacrum. An undercutting system is at least partially inserted into the aperture. The undercutting system includes an insertion apparatus, a probe assembly and a cutting assembly. The probe assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The probe assembly is manipulated within a joint between the ilium and the sacrum while the probe assembly is in the extended position. The cutting assembly is moved with respect to the insertion apparatus from a retracted position to an extended position. The cutting assembly is sharper than the probe assembly. The cutting assembly is manipulated within the joint between the ilium and the sacrum while the cutting assembly is in the extended position to form a fusion region. The undercutting system is removed from the aperture.

A differential dissecting instrument for differentially dissecting complex tissue is disclosed. The differential dissecting instrument comprises a handle and an elongate member having a first end and a second end, wherein the first end is connected to the handle. The differential dissecting instrument comprises a differential dissecting member configured to be rotatably attached to the second end and further comprises at least one tissue engaging surface. The differential dissecting instrument comprises a mechanism configured to mechanically rotate the differential dissecting member around an axis of rotation, thereby causing the at least one tissue engaging surface to move in at least one direction against the complex tissue. The at least one tissue engaging surface is configured to selectively engage the complex tissue such that the at least one tissue engaging surface disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

A cannula assembly for use in laproscopic surgery includes a cannula having a proximal end for use in orientating the assembly into an abdominal cavity, a distal end for insertion into a patient, and a passage through which surgical instruments can be inserted. An expandable feature in the form of an anchor is located toward the distal end of the cannula and is selectively expandable and collapsible. The feature in its expanded state prevents withdrawal of the cannula. A collar is pushed distally until it releasably cinches to the outside of the abdominal cavity thereby creating an airtight seal and stabilizing the assembly. The collar has a friction fit with the cannula designed to prevent excessive force against the cavity walls.
