  • Patent number: 11432624
    Abstract: The gauge enhancer body jewelry system allows individuals to increase their earlobes to the size they desire. It eliminates the need to constantly purchase new gauges as earlobes expand. It reduces pain associated with the enlargement process and forcing uncomfortably large gauges into earlobe holes. As designed it decreases the risk of infection from removing and replacing gauges. The present invention saves a considerable amount of time and frustration, and allows individuals to enlarge their earlobes at their own pace.

More specifically, the present disclosure relates to systems and methods for actively releasing an embolic coil from a delivery device into a body lumen of a patient. Delivery systems of the present disclosure may allow an embolic coil to be advanced external to the distal end of a delivery catheter without being automatically released, thereby allowing the embolic coil to be repositioned prior to deployment.

  • Patent number: 10874781
    Abstract: The invention resides in the field of introducing fluid pumps into a lumen and relates to a system for introducing a pump into a lumen which comprises a first sheath and a pump to be introduced into the first sheath, or a system which has a pump with a distal pump unit and a shaft catheter which emerges proximally to the pump unit. According to the invention one or two sheaths are used, the distal pump unit being pulled firstly into the distal end of one sheath, in order to avoid damage to a shaft catheter. Subsequently, the sheath receiving the pump unit is transferred into a further sheath or a receiving lumen.

  • Patent number: 10849615
    Abstract: A suturing device uses an inflatable balloon coupled to multiple arms and needles to place sutures at appropriate positions. In preferred embodiments the suturing device includes an elongated body having a working end, a controlling end, and a lumen. The elongated body is coupled to an arm having a distal end with a needle target, which is used to place a suture in an appropriate position relative to the aperture. An inflatable balloon is positioned in an area enclosed by the arm, such that inflating the balloon physically moves a needle towards the needle target.

  • Patent number: 10799243
    Abstract: An embolic device deployment system having a lumen with proximal and distal ends. An embolic device having a proximal retaining ring and an expandable member having a contracted and expanded state, with two apertures. The expandable member is disposed in the lumen in the expanded state. An engagement member has a distal loop extending through the retaining ring and a proximal loop extending into the lumen. The detachment member slides within the lumen and another of the apertures and is disposed through the loops. It comprises a bump on the detachment member between the loops. When the detachment member is in the distal loop and the distal loop is disposed within the retaining ring, the embolic device is in an engaged position. Pulling the detachment member withdraws it from the distal loop. The bump contacts the proximal loop to assist in the disengagement of the distal loop from the retaining ring to release the embolic device.

  • Patent number: 10792174
    Abstract: A bariatric device and method of causing at least partial satiety in a recipient includes positioning a body in a recipient, the body having a wall defining a lumen, the wall configured to generally conform to the shape and size of the proximal cardiac portion of the stomach. Force is exerted with the wall on the proximal cardiac portion of the stomach in the absence of food thereby activating receptors located in the proximal cardiac portion of the stomach, thereby influencing a neurohormonal feedback mechanism of the recipient to cause at least partial satiety by augmenting fullness caused by food and simulating fullness in the absence of food.

  • Patent number: 10779980
    Abstract: A intragastric device that contains a compressible free-floating structure and a sleeve attached thereto is provided. The device is considered to be anchorless as the sleeve is not physically attached to any portion of the GI tract. The device is configurable between a compressed pre-deployment configuration and an expanded post-deployment configuration. The free-floating device may be composed of a shape memory material such a nitinol. In some embodiments, the free-floating structure is space occupying and non-porous. The sleeve may be attached to the free-floating structure, such as with sutures and/or glue. In some embodiments, a stent may be inserted at the proximal end of the sleeve. A second free-floating structure may be connected to the free-floating structure such that there is an upper structure and a lower structure. In some embodiments, the gastrointestinal device is used to deliver prebiotic and/or probiotic therapy to a patient.

  • Patent number: 10758286
    Abstract: Methods and apparatus for accessing and repairing a vertebral disc include a pad with a central cut-out mounted to the skin of a patient or, alternatively, a pedicle-mounted support. An incision is made and then a corridor is created using an elongated guide and a series of dilating tubes. An access to the disc space is created through the superior articular process and the facet joint using the corridor defined by the dilating tubes. Nucleus material is removed from the disc space and the vertebral endplates are prepared. The disc space may be sized to select a suitable implant, which is advanced through the corridor and into the disc space following discectomy and endplate preparation. Bone graft material may be inserted into the disc space following installation of the implant and then posterior rigid fixation may be achieved using percutaneous pedicle screws, followed by closure of the site.

  • Patent number: 10758220
    Abstract: Adjustable-length surgical access devices are disclosed herein, which can advantageously allow an overall length of the access device to be quickly and easily changed by the user. The access devices herein can reduce or eliminate the need to maintain an inventory of many different length access devices. In some embodiments, the length of the access device can be adjusted while the access device is inserted into the patient. This can reduce or eliminate the need to swap in and out several different access devices before arriving at an optimal length access device. This can also reduce or eliminate the need to change the access device that is inserted into a patient as the depth at which a surgical step is performed changes over the course of a procedure. Rather, the length of the access device can be adjusted in situ and on-the-fly as needed or desired to accommodate different surgical depths.
