Patent number: 9492062Abstract: A visual insufflation obturator is provided. The obturator includes seals, valves, screens and/or various other tip features to eliminate the ingress of fluids, matter and/or gas that can disrupt the visual field of the laparoscope disposed within the obturator. The obturator provides additional features such as lens and anti-fog features to further increase visibility of the scope, efficiently insufflate the patient and ultimately provide an access channel into the insufflated abdomen once the visual insufflation obturator is removed.Type: GrantFiled: August 12, 2013Date of Patent: November 15, 2016Assignee: Applied Medical Resources CorporationInventors: Scott V. Taylor, Paul W. Balschweit, Jeremy J. Albrecht, Gary M. Johnson, Said Hilal, Zoran Falkenstein

Patent number: 8147458Abstract: A multi-seal trocar system includes a plurality of co-axial sealing elements adapted for forming a seal with either a large or small instrument. Small and large sealing elements are disposed in an in-line arrangement such that a-single port is provided for instrument insertion. A zero seal is disposed distally of the sealing elements to seal a working channel of the system and to prevent backflow when no instruments are inserted. The small sealing element is configured such that insertion of a large instrument automatically moves the small sealing element out of its path, thereby avoiding contact with the large instrument.Type: GrantFiled: September 10, 2008Date of Patent: April 3, 2012Assignee: Applied Medical Resources CorporationInventors: Charles C Hart, John R Brustad, Nabil Hilal, Said Hilal

Publication number: 20050222561Abstract: A surgical digitizing apparatus and procedure will typically involve a pad having discrete segments which may be arranged in a specific order to accommodate a particular procedure. The individual segments can then be used to accomplish both diagnostic and therapeutic functions. For example, the segments can be interrogated to produce a map of body tissue and then electrosurgically energized to perform a therapeutic function in accordance with the map. Communication with the discrete segments will typically be accomplished through a microprocessor and associated switching circuits.Type: ApplicationFiled: February 10, 2003Publication date: October 6, 2005Inventor: Said Hilal

Publication number: 20050165366Abstract: 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: January 28, 2004Publication date: July 28, 2005Inventors: John Brustad, Said Hilal, Nabil Hilal, Charles Hart, Gary Johnson, Serene Hilal, Ghassan Sakakine, Donald Gadberry, Edward Pingleton, Matthew Petrime, Payam Adlparvar, Carl Hadley, Kenneth Vu

Publication number: 20050165444Abstract: A tissue welding apparatus is adapted to fuse a first piece of tissue to a second piece of tissue which are disposed in a surface proximate relationship. An elongate shaft carries a first jaw, and a second opposing jaw moveable relative to the first jaw. At least one penetrating member is carried by the first jaw and moveable relative to the second jaw to create a channel through the first piece of material and the second piece of material. A source of heat is coupled to the penetrating member for denaturing the tissue defining the channel. This denatured tissue forms a column binding the first piece of tissue to the second piece of tissue. A chemical agent can be carried to the tissue with the penetrating member.Type: ApplicationFiled: January 16, 2003Publication date: July 28, 2005Inventors: Charles Hart, Gary Johnson, Said Hilal, John Brustad

Publication number: 20040167513Abstract: In electrosurgical system includes an electrosurgical generator providing power through an electrode, and a laser providing laser energy through an optical fiber. The electrode optical fiber and a source of environmental gas can all be included in a handpiece, catheter or other delivery device. In operation, the environmental gas can be released into the vicinity of an operative site and the laser activated to energize atoms along a pathway. Electrosurgical power can then be applied to ionize the items of the atoms of the pathway and create a path of least resistance for an electrosurgical arc. A reduction in the laser power required can be achieved by matching the photon frequency of the laser with the excitation frequency of the environmental gas. In a laparoscopic procedure, the insufflation gas may be used as the environmental gas.Type: ApplicationFiled: February 11, 2004Publication date: August 26, 2004Inventor: Said Hilal

Patent number: 6558350Abstract: A drainage catheter is adapted to drain fluid from the body cavity through a body conduit and includes an elongate tube having a distal end and a retention member disposed at the distal end and adapted for movement between the low-profile state facilitating insertion of the catheter and a high-profile state facilitating the tension of the catheter in its operative position. A woven mesh forms at least a portion of one of the tube and the retention member, and can be made permeable or impermeable in various regions of the catheter. The woven mesh can be formed of filaments heat-settable so that the catheter automatically moves to the high-profile state. Insertion of the catheter can be facilitated using an obturator and a guidewire in an associated method, an obturator facilitating insertion of the catheter can be removed to permit the catheter to automatically return to a normal, high-profile state.Type: GrantFiled: June 20, 2000Date of Patent: May 6, 2003Assignee: Applied Medical Resources Corp.Inventors: Charles C.

Patent number: 6183503Abstract: A stent is adapted for disposition in a body conduit of a patient and comprises a mesh formed in the configuration of a tube and having an axis and axial convolutions, which facilitate movement between a low-profile state and a high-profile state. The tube in the low-profile state has an elongate configuration and a wall with a first thickness and first tube strength. The tube in the high-profile state has a compressed configuration and a wall with a second thickness greater than the first thickness and a second hoop strength greater than the first hoop strength. An associated method of use includes the steps of mounting the step on a catheter between first and second enlargement members, increasing the size of the enlargement members, and moving the enlargement members to axially compress the stent to the high-profile state. An associated method of manufacture includes the steps of corrugating the mesh on a mandrel by moving the ends of the mesh toward each other.Type: GrantFiled: September 17, 1999Date of Patent: February 6, 2001Assignee: Applied Medical Resources CorporationInventors: Charles C.
