Publication number: 20230055249Abstract: A medical device system for the delivery of energy to a region of a patient's anatomy is provided. An introducer tube defines a lumen therein and bears a first electrode. A second electrode is movable within the lumen between a retracted position and an extended position. In the retracted position, the second electrode is substantially disposed within the lumen. In the extended position, the second electrode extends at least partially beyond the distal end of the introducer tube. In one form, the introducer tube is configured to substantially hold the second electrode within the lumen in a predetermined orientation in the extended position, and the introducer tube prevents the second electrode from substantially rotating within the lumen of the introducer tube during movement into the extended position. In one form, the introducer tube is more flexible in a first plane than in a second plane.Type: ApplicationFiled: September 26, 2022Publication date: February 23, 2023Inventors: Brandon James Shuman, Hugo X.

Publication number: 20220249076Abstract: A device having a sheath, a medical device, a stylet, a handle and a plunger device. The handle includes portions connected proximal ends of the sheath, the medical device and the stylet and a chamber portion connected to the actuator. The chamber portion includes a volume of space configured to volumetrically connect to at a lumen of the medical device, the sheath or the stylet and a plunger device configured to be slidably received within the chamber portion. The plunger device is able to pneumatically isolate a proximal portion of the volume of space from a distal portion of the volume of space. Proximal movement of the stylet and the plunger device cause a suction effect (i.e., reduced pressure) at the distal end of the sheath, the medical device and/or the stylet.Type: ApplicationFiled: March 29, 2022Publication date: August 11, 2022Inventors: Hugo X.

Patent number: 9358013Abstract: An intra-bronchial device placed and anchored in an air passageway of a patient to collapse a lung portion associated with the air passageway. The device includes a support structure, an obstructing member carried by the support structure that reduces ventilation to the lung portion by preventing air from being inhaled into the lung portion, and at least one anchor carried by the support structure that anchors the obstruction device within the air passageway. The anchor may engage the air passageway wall by piercing or friction, include a stop dimensioned for limiting the piercing of the air passageway wall, and may be releasable from the air passageway for removal of the intra-bronchial device. The anchors may be carried by a peripheral portion of the support structure, or by a central portion of the support structure. The obstructing member may be a one-way valve.Type: GrantFiled: February 13, 2015Date of Patent: June 7, 2016Assignee: Spiration, IncInventors: David H. Dillard, Hugo X. Gonzalez, Seung Yi, Lauri J.

Patent number: RE45921Abstract: A resection device and method permits safe and efficient encapsulation, isolation and resection of body tissue. The device includes a sheath of flexible and severable material configured to receive the body tissue to be resectioned as it is drawn therein. The sheath may be expandable and held in an expanded condition as the body tissue to be resectioned is drawn into the sheath. Thereafter, the sheath is permitted to collapse about the body tissue to contain and constrict the body tissue. Once the body tissue to be resectioned is disposed in the sheath, the sheath is severed to resection the body tissue.Type: GrantFiled: November 9, 2011Date of Patent: March 15, 2016Assignee: Spiration, Inc.Inventors: Clifton A.
