Patent number: 7992261Abstract: Disclosed is a closure system used in combination in any of a variety of applications including clothing, for example as a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. The closure system allows a user to quickly loosen the lace and inhibits unintentional and/or accidental loosing of the lace.Type: GrantFiled: August 20, 2007Date of Patent: August 9, 2011Assignee: Boa Technology, Inc.Inventors: Gary R. Hammerslag, Mike Mayberry, Mark Soderberg

Patent number: 5820592Abstract: The invention provides a guide catheter comprising an elongate tubular body having a proximal end and a distal end, and at least one central lumen extending axially therethrough. At least one torque control wire extends axially therethrough. In one embodiment, an actuator is connected to the torque control wire. Torquing the actuator results in steering or aiming the guide catheter. In another embodiment, a deflection wire extends through the catheter body. Manipulation of a control on the deflection wire deflects a distal portion of the deflection wire.Type: GrantFiled: July 16, 1996Date of Patent: October 13, 1998Inventor: Gary R. Hammerslag

Patent number: 5480382Abstract: A steerable guidewire for percutaneous transluminal insertion into the vascular system and controlled negotiation of branches and turns therein, comprises an elongated tubular support which includes a proximal hypotube section and a distal spring coil. A movable pull wire extends through the support structure and is attached at its distal end to the rounded tip of the guidewire. A deflection section is provided in which a flexible deflection ribbon is mounted. The distal end of the deflection ribbon is attached to the pull wire and its proximal end is attached to the spring coil. When the pull wire is pulled axially, it applies a compressive force to the deflection ribbon which in turn applies a lateral component of force to the pull wire and spring coil in the deflection region. This causes the guidewire to bend with the deflection ribbon functioning as a fulcrum around which the guidewire bends.Type: GrantFiled: September 2, 1994Date of Patent: January 2, 1996Assignee: Pilot Cardiovascular Systems, Inc.Inventors: Julius G. Hammerslag, Gary R. Hammerslag

Patent number: 5378234Abstract: A coil polymer composite tubular body is disclosed, such as for use in medical applications. The body comprises a spring coil having at least one central lumen extending axially therethrough, for receiving medical implements, fiber optics, suction or transmission of fluids such as for irrigation or drug delivery. An elastomeric layer on the spring coil provides a substantially water impermeable seal. In one particular embodiment, the composite tubular body is provided with a laterally deflectable distal tip.Type: GrantFiled: May 14, 1993Date of Patent: January 3, 1995Assignee: Pilot Cardiovascular Systems, Inc.Inventors: Gary R.

Patent number: 5372587Abstract: A steerable tubular sheath is disclosed, such as for use in medical applications. The tubular sheath comprises an elongate flexible tubular body, having a laterally deflectable distal tip. Lateral deflection of the tip is accomplished by axial displacement of at least one pull wire extending through the housing. The housing comprises at least one central lumen extending axially therethrough, for receiving medical implements, fiber optics, suction or transmission of fluids such as for irrigation or drug delivery. In one particular embodiment, the steerable sheath is particularly adapted for irrigation and aspiration of the contents of the lens capsule of the eye.Type: GrantFiled: March 15, 1993Date of Patent: December 13, 1994Assignee: Pilot Cariovascular Systems, Inc.Inventors: Julius G.

Patent number: 5108368Abstract: An elongate steerable implement is disclosed, which may be either a steerable guidewire or catheter for coronary angioplasty applications. A floppy steerable tip on a steering region at the distal end of the implement and a control device at the proximal end are connected by means of a plurality of axially movable deflection wires extending throughout the implement. Manipulation of the control permits deflection of the steering region throughout a full 360.degree. range of motion about the axis of the implement, without axial rotation or "torquing" thereof. In another embodiment, a steering ribbon is disclosed which permits steering by lateral deflection of the tip into a deflected or bent position and then permits straightening the tip back to its original position.Type: GrantFiled: September 17, 1990Date of Patent: April 28, 1992Assignee: Pilot Cardiovascular System, Inc.Inventors: Julius G.
