Publication number: 20110166424Abstract: An incrementally adjustable wound retractor, which provides access to a body cavity, includes an inner ring having a diameter greater than the desired diameter of the wound incision, an outer ring having an annular axis and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve disposed in a generally cylindrical form between the inner and outer rings. The outer ring includes first and second circular tubes spaced apart axially with each including a lumen having a rigid, noncompliant split hoop placed therein. The outer ring may be rolled over itself and around the annular axis to retract the sleeve with sufficient force to stretch the incision to the desired diameter. A gel cap seal may be coupled to the outer ring outside of the biological body to seal the opening produced by the wound retractor between the body cavity and outside the body cavity.Type: ApplicationFiled: March 17, 2011Publication date: July 7, 2011Applicant: Applied Medical Resources CorporationInventors: Jeremy J. Albrecht, Jennifer T. Ko, Gary M. Johnson, John R. Brustad, Donald L. Gadberry

Patent number: 7947058Abstract: The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers.Type: GrantFiled: October 1, 2004Date of Patent: May 24, 2011Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz A.

Patent number: 7945800Abstract: Apparatus for synchronizing signals. For memory devices, such as SDRAMs, implementing a synchronization device to synchronize one signal, such as an external clock signal with a second signal, such as a data signal, tuning elements may be provided at various points in the signal path of the synchronization device. The tuning elements are designed to be identical, such that a single design may be used to a signal mismatch that is produced in either direction, using a single design. The tuning elements may be implemented to provide uniformity in the access time through a range of conditions, such as drain voltages and temperatures.Type: GrantFiled: July 30, 2006Date of Patent: May 17, 2011Assignee: Round Rock Research, LLCInventors: Tyler J.

Publication number: 20110112374Abstract: The invention relates to a hand access laparoscopy device having a gelcap, a retainer, a sleeve and a retention ring. The gelcap includes gel that is bonded to a cap. The cap includes an inner cylindrical wall to which the gel in bonded, thereby providing a sealing area between the device and the wound in a body wall. By securing the gel to the inner cylindrical wall, the thickness of the gel and corresponding cap is minimized along with the overall footprint of the device. With the gel thickness reduced and able to be substantially flush, the “doming” phenomenon produced by insufflation of a patient's abdomen is reduced.Type: ApplicationFiled: January 14, 2011Publication date: May 12, 2011Applicant: Applied Medical Resources CorporationInventors: John R. Brustad, Jeremy J. Albrecht, Nabil Hilal, Gary M. Johnson, Charles C. Hart

Publication number: 20110054260Abstract: A surgical access system comprises a wound retractor comprising an outer anchor, an inner anchor, and a flexible, tubular sheath extending therebetween. Embodiments of the outer anchor comprise an outer ring rotatable around an annular axis thereof, thereby rolling the sheath therearound when retracting an incision or opening in a body wall. The sheath comprises a plurality of fibers or strands that improve the abrasion and puncture resistance thereof. Consequently, the surgical access system is useful in procedures in which damage to the sheath is likely, for example, orthopedic hip replacement, and spinal procedures. In some embodiments, the sheath tapers from the outer ring to the inner ring.Type: ApplicationFiled: August 31, 2010Publication date: March 3, 2011Applicant: Applied Medical Resources CorporationInventors: Jeremy J.

Publication number: 20110021879Abstract: Devices, methods, and systems provide a surgical access device comprising an internal retractor device integrated with or coupled to a body wall or wound retractor. The wound retractor retracts an opening in a body wall into a body cavity, while the internal retractor permits a user to control the positions of internal structures within the body cavity, thereby permitting a user to define a surgical field. Embodiments of the internal retractor are adjustable.Type: ApplicationFiled: July 21, 2010Publication date: January 27, 2011Applicant: Applied Medical Resources CorporationInventors: Charles C.

Publication number: 20110005661Abstract: The invention primarily is directed to a medical tubing adapted for insertion into a body tissue or cavity and method of manufacturing different variations of the tubing along a length of the tubing. The tubing comprises a plurality of individual, discrete, generally ring-shaped elements arranged in series and fused or bonded together forming a continuous tubular structure. The ring-shaped elements may be formed of a thermoplastic or a thermoset material. The ring-shaped elements may include plastic rings, metallic rings, un-reinforced plastic rings and/or metal reinforced plastic rings assembled along the length of the tubular structure to provide variable flexibility and kink-resistance. The tubular structure may have a cross-section of any geometric shape and it may be bent, twisted or curved without kinking. The ring-shaped elements may have different flexural modulus.Type: ApplicationFiled: September 8, 2010Publication date: January 13, 2011Applicant: Applied Medical Resources CorporationInventors: JOHN R.

Patent number: 7808289Abstract: An apparatus and method for generating phase-related clocks are disclosed. A clock input is delayed by an alignment magnitude to generate a first phase signal. The first phase signal is delayed by the phase alignment magnitude to generate a first phase delay signal. The clock input is delayed by a phase delay magnitude to generate a second phase signal and the second phase signal is delayed by about the phase delay magnitude to generate a last phase delay signal. A phase difference is detected between the first phase delay signal and the last phase delay signal and adjustments are made to at least one of the phase delay magnitude and the alignment magnitude.Type: GrantFiled: August 30, 2007Date of Patent: October 5, 2010Assignee: Micron Technology, Inc.Inventor: Gary M.
