  • Patent number: 10022173
    Abstract: Systems and methods for stabilization of a bone structure. A distal curved portion of a delivery tube is directed through an access cannula to a target site within the bone structure. The distal curved portion forms a curved path with respect to the access cannula. A cavity-forming device including an expandable member is adapted to be curved by a support structure in the expandable member. The curve may be provided by tracking the curved path formed by the delivery tube. The support structure may provide trackability and pushability to the expandable member of the cavity-forming device as it is directed into the curved path. Curable material is delivered through the delivery tube into a cavity formed by expanding the expandable member within the bone structure. The cavity is offset relative to the access cannula and/or the distal curved portion of the delivery tube.

  • Patent number: 9895192
    Abstract: An intrauterine device includes an articulating array. The intrauterine device can be operated by articulating the articulating array into an installed position or geometry within the uterus of a patient. Further, the articulating array can be constructed to include an insertion geometry have a smaller cross section than an installation geometry. The articulating array can also be constructed to be housed within a sheath in the intrauterine device. Once the sheath has been inserted into a patient, for example through the patient's cervix, the articulating array can be deployed in its insertion geometry and then articulated into an installed position. The articulating array can include a plurality of expansion chambers. The expansion chambers can be constructed and arranged to take on the installed geometry when expanded. In one embodiment, the purpose of the articulating array is to position a conductive array within the patient's uterus enabling ablation of the uterine lining.

  • Publication number: 20140303447
    Abstract: The invention is a simple surgical drape system for female urology procedures that provides sealed isolation of top versus bottom sides of the drape and only exposes the female urethral meatus area for the procedure. It is achieved by a combination of a drape with a fenestration, a labia spreader where the drape fenestration is attached to provide a seal, and local illumination of the meatus area integrated in the drape system for safer and easier instrument insertion. The labia spreader also frees up one of the operator's hands and provides protection for false catherization. The labia spreader can have a vaginal inserted portion for precise position fixation of the drape fenestration to the female. The drape system also provides improved liquid management made possible by the unique combination of drape and labia spreader acting as seal between the two sides of the drape.

  • Patent number: 8845529
    Abstract: A surgical access assembly includes an access port, a seal anchor and a sealing adapter. The access port includes proximal and distal rings and a sleeve defining a passage therethrough. The sleeve extends between the proximal and distal rings. The seal anchor is adapted to be at least partially disposed in the access port. The sealing adapter includes proximal and distal end portions. The distal end portion is configured and dimensioned to engage the seal anchor in a sealing relation therewith. The proximal end portion is configured and dimensioned to engage a least a portion of the distal ring of the access port in a sealing relation therewith, wherein the sealing adapter is transitionable between a first state in which the sealing adapter has a first diameter and a second state in which the sealing adapter has a second diameter. The second diameter is larger than the first diameter.

  • Publication number: 20140249374
    Abstract: A device for creating an operative space within a body lumen for the performance of a medical procedure, including a pressurizable, expandable balloon element insertable into the body lumen. The balloon element includes an interior space for receiving an inflation fluid. The device further includes an ingress valve coupled with the balloon element and insertable therewith into the body lumen. The ingress valve is capable of being opened to allow the interior space to be filled with the inflation fluid and closed to retain the inflation fluid in the interior space. The device may also include an egress valve coupled with the balloon element and insertable therewith into the body lumen. The egress valve is closed when the interior space is filled with the inflation fluid and is capable of being opened to allow the inflation fluid to vent from the interior space.
