Disclosed herein are inflatable balloon apparatuses for use in stopping massive blood flow from a uterine wall due trauma or disease. Also disclosed is a method for using the apparatuses.

Provided is a retractor that makes it possible to reduce operation costs, is less likely to cause damage to surgical incision sites, do not reduce workability, and also makes it possible to easily maintain the desired surgical field and to change the surgical field or widen or narrow the area of the surgical field, depending on the surgical situation. The retractor 1 for holding a surgical incision open and maintaining a surgical field during an operation includes a belt-shaped body A made of a wire; and a connecting part B that is provided at one end portion of the belt-shaped body A and capable of being connected to another end portion or an intermediate portion of the belt-shaped body A so that the belt-shaped body A can be formed into a loop of a desired size. The retractor 1 is so configured that when the belt-shaped body A is formed into a loop, the outer surface of the belt-shaped body A resists the force generated at the surgical incision and acting in such a direction as to close the surgical incision.

A surgical assembly includes a surgical instrument and a holder. The surgical instrument includes an elongate body and an end effector. The elongate body has a proximal portion and a distal portion that defines a longitudinal axis therealong. The proximal portion is movable relative to the distal portion between a first condition and a second condition. In the first condition, the proximal portion is parallel to the longitudinal axis. In the second condition, the proximal portion is non-parallel to the longitudinal axis. The holder is configured to be coupled to the elongate body to selectively retain the proximal portion of the elongate body in the first condition.

A medical device of the present invention includes one or more anchors and an elongated member. Advantageously, the elongated member may be coupled to the anchors. The elongated member and anchors are configured to generate a force on a mesentery. The force is sufficient to retract a bowel of the patient into an upper portion of an abdominal cavity of the patient. When the patient is in a slightly angled position, the weight of the medical device pulls the mesentery into the upper abdomen. Since the bowel is connected to the mesentery, the device also indirectly pulls up the bowel. In some implementations of the device, a slight angle may be unnecessary. In others, the device may also inversely retract the mesentery and attached organs into the lower abdomen to facilitate surgical access to the upper abdomen. In some implementations of the device, a slight angle may be unnecessary.

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

Clip for an aneurism suitable for being implanted into tissue in which an aneurism has formed and carrying out a tight closure of the aneurism which comprises a pair of claw members (2a, 2b) made of non-metallic material, said claw members being provided with articulated joining means (3) which allow the rotation of the pair of claw members around a pivot (4) which interlocks them, the clip being able to adopt at least one opening position (A) and one closure position (B); the clip being provided with at least one spring element (6) at least partially housed in the clip which bends to arrange the clip in closure position which comprises at least one flexible (7) and elastic element with a section with arced configuration (8), press-fitted with two opposing ends (9a, 9b) each one exerting pressure on a different claw member both in the opening and in the closure position.

An actuation mechanism for actuating an electrosurgical end effector includes a housing and a shaft assembly extending distally from the housing. The shaft assembly includes an elongate collar, a shaft extending through the elongate collar, and a longitudinal bar axially movable relative to the shaft. The elongate collar has an internal threadform extending along a length thereof. The longitudinal bar includes a proximal end having an extension engaged to the internal threadform of the elongate collar and a distal end configured to be coupled to a knife blade of an electrosurgical end effector. Rotation of the elongate collar axially moves the longitudinal bar relative to the elongate collar to move the knife blade.

A dynamic stabilization assembly includes a core, typically in the form of a tensioned cord, at least one pair of bone anchors, a spacer surrounding the core located between the bone anchors, at least one elastic bumper and at least one fixing or blocking member. The core is slidable with respect to at least one of the bone anchors, the spacer and the bumper. The bumper is compressed. Bone screws of the assembly include closure structures that lock against the bone screw independent of any fixing or sliding of the core with respect to the bone screw.

A surgical retractor for retracting body tissue in a therapeutic procedure includes a blade having a body portion and a plurality of elongate elements extending from the body portion. The plurality of elongate elements is separated a distance from one another along a length of the body portion and form one or more gaps therebetween. The plurality of elongate elements is connected by one or more cross connectors transverse to the plurality of elongate elements. The retractor blade is configured to permit movement of a lung being retracted.

Embodiments of a leaflet clip device and method of reducing regurgitation through a native heart valve are disclosed. A leaflet clip device can include an elongated clipping member having a first end portion and a second end portion and a tensioning mechanism coupled to the clipping member. The leaflet clip device can further include one or more tensioning members disposed within a lumen of the clipping member, wherein the one or more tensioning members are operatively connected to the tensioning mechanism to transform the clipping member from a delivery configuration to an implantation configuration.
