Patent number: 6063080Abstract: A radio frequency (RF) ablation catheter system utilizes a flexible, tubular electrode that is selectively extendable from a distal end of a catheter body. The flexible, tubular electrode creates a continuous linear lesion when a longitudinal side of the electrode is arcuately positioned against an interior wall of the human body and the electrode is energized while a cooling fluid passes through the electrode. The catheter system also includes mechanisms for remotely manipulating and extending the electrode. Preferably, the catheter body include a catheter shaft and a flexible tip section such that the distal end of the catheter is steerable. The invention also includes a method of operating the RF catheter ablation system so as to create arcuate linear lesions.Type: GrantFiled: May 6, 1998Date of Patent: May 16, 2000Assignee: Cordis Webster, Inc.Inventors: Dale K. Nelson, Steven D. Savage, Brad D. Pedersen, Whitney A. McFarlin

Patent number: 4817671Abstract: A high pressure mechanical plug device for sealing and locking into a high interior pressure pipeline. The mechanical plug device has a hollow cylindrical body structure with an end wall and a side wall structure having a plurality of apertures. A piston structure having an end wall and a frustoconical ram of a predetermined slope is provided for movement in the cylindrical body structure. An elastomeric sealing member is in communication with the end wall of the piston structure. A plurality of rigid securement members are provided for extension through the apertures of the cylindrical body structure and for slidingly engaging the frustoconical ram. A draw bolt extending axially from the frustoconical ram through the end wall of the cylindrical body is provided with a nut to move the piston structure into the cylindrical body to seal and lock the plug device in the pipeline.Type: GrantFiled: January 21, 1988Date of Patent: April 4, 1989Assignee: Cherne Industries, Inc.Inventors: Allen D. Mathison, Dale K. Nelson

Patent number: 4763511Abstract: A separable, lightweight and inflatable pipe joint sealing and testing apparatus for large diameter pipes having a multi-membered arched channel support structure having a circular configuration, and having three parallelly disposed channel members extending outward therefrom, and having outer channel members and a centrally disposed testing channel member. A unitary inner sleeve sealing member coextensive with the channel members is provided for covering the channel support structure. The pipe joint sealing and testing apparatus further has a pair of inflatable annular sealing ring members for placement in the outer channel members, a compressed air source means in communication with the pair of inflatable sealing rings, and a compressed fluid ingress and egress structure through the port of the centrally disposed channel member.Type: GrantFiled: November 21, 1986Date of Patent: August 16, 1988Assignee: Cherne Industries, Inc.Inventors: Allen D.

Patent number: 4614206Abstract: A multi-size expansible pneumatic plug device for sealing the interior of a pipeline section. The expansible plug device has interchangeable front and rear circular rigid support members for supporting the remaining elements of the device and each rigid support member has a generally flat end portion and a body portion having parallelly disposed circumferential ridges to form first and second grooved portions. The circumferential ridges have top surfaces of an equal predetermined inclined slope. At least one of the rigid support members additionally has an air inlet means. An exteriorly smooth and interiorly corded elastomeric sleeve member is provided for expansion to seal against the interior wall of a pipeline section. The sleeve member has interiorly disposed parallel circumferential rings of a predetermined spacing inward its ends. A pair of strapping clamp members hold the sleeve member rings matingly between the parallel ridges and in the grooved portions of each rigid support member during assembly.Type: GrantFiled: November 14, 1985Date of Patent: September 30, 1986Assignee: Cherne Industries, Inc.Inventors: Allen D.
