Patent number: 8323305Abstract: A device for expansion within a blood vessel having a wall defining a lumen in the body. The device comprises an elongated tubular member having proximal and distal extremities and having a longitudinal axis. An expansile member is carried by the distal extremity of the elongated tubular member and is movable between contracted and expanded configurations. A deformable membrane having proximal and distal outer surfaces at least partially covers the expansile member in the expanded configuration. The proximal and distal outer surfaces have substantially different configurations when the expansile member is in the expanded configuration. Deployment means is carried by the proximal extremity of the elongated tubular member and is coupled to the expansile member for moving the expansile member between the contracted and expanded configurations. A handle assembly is carried by the proximal extremity of the elongated tubular member and coupled to said deployment means.Type: GrantFiled: November 19, 2003Date of Patent: December 4, 2012Assignee: Cardiva Medical, Inc.Inventors: Gordon H. Epstein, Todd E. Lempert, Brian B. Martin, David M. Taylor, Richard M. Romley, Zia Yassinzadeh, Glenn Foy

Patent number: 6056769Abstract: A device for expansion within a blood vessel having a wall defining a lumen in the body. A first elongate tubular member has proximal and distal extremities and has a longitudinal axis. An expansile member is carried by the distal extremity of the first elongate tubular member is and movable between contracted and expanded positions. The expansile member has a predetermined configuration in the expanded position. A deformable membrane covers the expansile member, and is sized so as to be capable of overlying and underlying the expansile member in the expanded position. A deployment mechanism is carried by the proximal extremity of the first elongate tubular member and is adapted to be operated by the human hand for controlling movement of the expansile member between the contracted and expanded positions. A deployment mechanism includes a push-pull wire with proximal and distal extremities and extends through the first elongate tubular member and is coupled to the expansile member.Type: GrantFiled: July 31, 1998Date of Patent: May 2, 2000Assignee: BioInterventional CorporationInventors: Gordon H.

Patent number: 6056770Abstract: A device for expansion within a blood vessel having a wall defining a lumen in the body. The device comprises an elongated tubular member having proximal and distal extremities and having a longitudinal axis. An expansile member is carried by the distal extremity of the elongated tubular member and is movable between contracted and expanded configurations. A deformable membrane at least partially covers the expansile member and is sized so as to be capable of expanding as the expansile member moves from the contracted configuration to the expanded configuration. Deployment members are carried by the proximal extremity of the elongated tubular member and are coupled to the expansile member. The deployment members are adapted to be capable of moving the expansile member between the contracted and expanded configurations. A handle assembly is carried by the proximal extremity of the elongated tubular member and coupled to the deployment members.Type: GrantFiled: February 1, 1999Date of Patent: May 2, 2000Assignee: BioInterventional CorporationInventors: Gordon H.

Patent number: 5782860Abstract: A closure device for percutaneously forming a closure of a puncture in the tissue of human body. The device comprises a flexible elongate tubular member having proximal and distal extremities and a longitudinal axis. The flexible elongate tubular member has a first lumen extending from the proximal extremity to the distal extremity. A closure assembly is carried by the distal extremity of the flexible elongate tubular member and is movable between contracted and expanded positions. The closure assembly includes a closure mechanism covered by an impermeable membrane. A handle is carried by the proximal extremity of the flexible elongate tubular member and is adapted to be grasped by the human hand. A deployment mechanism is carried by the handle and extends through the flexible elongate tubular member and is coupled to the closure assembly for moving the closure assembly from the contracted position to the expanded position.Type: GrantFiled: February 11, 1997Date of Patent: July 21, 1998Assignee: BioInterventional CorporationInventors: Gordon H.
