  • Patent number: 9833623
    Abstract: A method is described for decreasing activity of at least one sympathetic nerve, nerve fiber or neuron innervating at least one blood vessel in the pulmonary vasculature of a patient to ameliorate pulmonary hypertension. In one embodiment, the method may involve advancing an intravascular treatment device to a target location in a target blood vessel within the pulmonary vasculature of the patient and using the treatment device to decrease activity of at least one sympathetic nerve, nerve fiber or neuron innervating the target blood vessel at or near the target location to ameliorate pulmonary hypertension.

  • Patent number: 9788823
    Abstract: Several methods to reduce surgical site infections include inserting a surgical access device into an incision, retracting tissue, and introducing fluid into the surgical access device such that the fluid exits the surgical access device and irrigates a surgical site. Other methods do not include introducing fluid into a surgical access device but include suctioning a fluid into the surgical access device and removing the fluid from the body.

  • Publication number: 20140316455
    Abstract: A method for performing a surgical or medical procedure on a portion of a patient's body within a surgical environment enclosure may involve preparing the surgical environment enclosure for performing the procedure, advancing the portion of the patient's body into the surgical environment enclosure through a first port on the enclosure, and performing the surgical or medical procedure on the portion of the patient's body inside the surgical environment enclosure, through at least a second port on the enclosure. The first port forms a seal around a surface of the patient's body upon or after insertion. In some embodiments, neither the entire body of the patient nor an entire body of any medical or surgical personnel fully enters the surgical environment enclosure during performance of the surgical or medical procedure.
