  • Patent number: 10869663
    Abstract: An adjunct material for use with an end effector in a surgical instrument is provided that has at least one projection configured to mate with a corresponding recess formed in at least one jaw, such as a cartridge or anvil, of the end effector. The at least one projection can be one or more discrete projections or longitudinal projection(s) extending between distal and proximal ends of the adjunct material. An applicator member can be used to apply force to the adjunct material to thus cause the adjunct material to mate with the jaw of the end effector. The applicator member can be configured told the adjunct material and can be clamped between the jaws of the end effector to release the adjunct material onto the jaw. Also, an applicator member can be used to push portions of an adjunct material into corresponding recesses in a jaw.

  • Patent number: 10376674
    Abstract: Novel systems for and methods of delivering therapeutic agents to target tissues are disclosed. The method of delivering a therapeutic agent to a target tissue involves identifying a target tissue via an imaging modality and then using a guidewire capable of anchoring in tissue to advance a cannula to the target tissue. The guidewire and novel cannula configurations enable rapid and repeated treatments of the target tissue without the need for subsequent imaging. The cannula is coupled to a source of ultrasound, radiation, radiofrequency energy, or chemotherapeutic agents which can then be delivered to from the cannula the target tissue. The system and method can be used to treat tumors that are small or surgically inoperable. In addition, the system can be used to treat lymphatic tissue that may contain metastases from the tumors.

  • Patent number: 9855164
    Abstract: Methods and devices comprised of a collapsible insert member and shaping member for treating obstructive sleep apnea are described. The insert member is placed in the tongue or other tissue forming the airway of the patient and has a lumen to accommodate the shaping member. The shaping member is inserted into the insert member by the patient just prior to sleep and removed upon waking. A variety of shaping members are available to treat patients on an individual basis, i.e., to match their particular anatomic condition that is causing their apnea or snoring. The shaping member can be made from nitinol, stainless steel, or any other known biocompatible implant material capable of providing a change in the tissue response to stress.

  • Patent number: 9238123
    Abstract: The present invention is related to a polymeric vehicle for delivery of bioactive agents, and preferably, for the delivery of one or more bioactive agents. The invention is also directed to a percutaneous device securing and drug delivery device comprising, as a component thereof, a material which delivers antimicrobial and/or other wound-healing factors at the site of the insertion of the catheter into the body. The device, when applied as described herein, provides complete anti-microbial coverage around the entry point of a percutaneous device and, preferably for a length greater than the diameter of the device. The present invention is also directed to methods for using such devices in combination with percutaneous devices primarily to reduce site infections.

  • Patent number: 8911424
    Abstract: Methods and devices for preventing urinary tract infections in catheterized patients are disclosed. The device may be a cylindrically shaped antimicrobial hydrogel having a central opening and a slit along its length so that it can be applied directly over a previously inserted urinary catheter. An optional locking mechanism disposed about the slit can be used to secure the antimicrobial device to a catheter shaft. The antimicrobial device has features that conform to tissues near both male and female urethral openings. The inner surface of the device is adapted to provide for releasable engagement with the shaft of the urinary catheter. In one embodiment, the device may be placed on a urinary catheter prior to inserting the catheter in a patient. Locking fittings to secure the antimicrobial device against the urethral opening may also be used. Antimicrobial agents can be incorporated within the hydrogel or coated onto its surface.

  • Patent number: 8678008
    Abstract: An auxiliary airway for treating obstructive sleep apnea is formed by implanting an elongated conduit beneath a pharyngeal wall of a pharynx. The elongated conduit has a proximal end in communication with a first region of the pharynx, a distal end in communication with a second region of the pharynx, and a section extending beneath the pharyngeal wall for bypassing an oropharynx region of the pharynx. The system includes a first opening in the pharyngeal wall in communication with a first opening in the elongated conduit, and a second opening in the pharyngeal wall in communication with a second opening in the elongated conduit. The system has a first anastomotic connector for coupling the first opening in the pharyngeal wall with the first opening in the conduit, and a second anastomotic connector for coupling the second opening in the pharyngeal wall with the second opening in the conduit.

  • Patent number: 8556797
    Abstract: A magnetic implant for treating sleep disorders includes a first anchor, a first magnet coupled to the first anchor, a tongue anchor, a second magnet coupled to the tongue anchor, and a support for aligning the first and second magnets so that a repelling force is generated between the magnets for urging the second magnet away from the first magnet. In one embodiment, the support aligns a magnetic pole of the first magnet with a repelling magnetic pole of the second magnet, guides movement of the first and second magnets relative to one another, and maintains the first magnet at a fixed distance from the first anchor. In one embodiment, the repelling force urges the second magnet toward the first anchor. The first anchor may be connected to bone or soft tissue.

  • Patent number: 8303609
    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned.
