Patent number: 8932290Abstract: A tissue ablation probe is provided. The tissue ablation probe comprises an elongated shaft, at least one electrode tine carried by the elongated shaft, at least one tine exit from which the electrode tine(s) can be deployed from the elongated shaft and retracted within the elongated shaft, and a sheath covering the electrode tine exit(s). The sheath may, e.g., line an exterior surface of the elongated shaft or an interior surface of the elongated shaft. The sheath has at least one tine valve (e.g., a slit) positioned over the electrode tine exit(s) and configured to open when the electrode tine is deployed and to close when the electrode tine(s) is retracted. In one embodiment, the tine valve(s) is configured to open in response to pressure exerted during deployment of the electrode tine(s). In another embodiment, the tine valve(s) is configured to hinder the entry of biological material within the elongated shaft.Type: GrantFiled: March 21, 2013Date of Patent: January 13, 2015Assignee: Boston Scientific Scimed, Inc.Inventors: Kimbolt Young, Gerald M. Hubbs, Steve Pickett, Gene McCallister, John Hewitt, Jeffrey W. Zerfas

Publication number: 20120283643Abstract: A catheter assembly includes an internal bolster comprising a plurality of resilient members collectively forming an anchor at a first end of the catheter. Each resilient member is reversibly transformable between a spiral shape, when at rest, and a straightened shape, when forcibly unfurled. The catheter assembly may be used in a method for inserting a gastrostomy tube into a patient. The catheter assembly is inserted into the patient's stomach with the resilient members in the unfurled straightened state. Once the resilient members have entered the patient, the resilient members are allowed to return to the relaxed spiral shape, thereby anchoring the catheter assembly in the patient.Type: ApplicationFiled: May 8, 2012Publication date: November 8, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Changqing LI, Gene McCALLISTER

Patent number: 8192419Abstract: A catheter assembly including an internal bolster. According to one embodiment, the catheter assembly includes a medical catheter preferably made of extruded silicone rubber. The catheter is shaped to include a cylindrical wall defining a primary longitudinal bore. A plurality of secondary longitudinal bores is provided in the cylindrical wall, the secondary bores being evenly spaced around the primary bore. The assembly also includes a plurality of identical resilient members collectively forming an anchor at a first end of the catheter. Each resilient member comprises a resilient wire and a protective jacket. Each wire is made of a shape-memory material and is reversibly transformable between a spiral shape, when at rest, and a straightened shape, when forcibly unfurled. One end of each wire is disposed within a secondary bore of the catheter, with the remainder of each wire extending out from the catheter.Type: GrantFiled: December 21, 2010Date of Patent: June 5, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Changqing Li, Gene McCallister
