Patent number: 10918814Abstract: An insufflating surgical instrument adapted for movement across an abdominal wall to insufflate an abdominal region of a patient is disclosed. The instrument comprises a shaft having an insufflation channel extending between a proximal end and a distal end, the insufflation channel being adapted for connection to a source of fluid under pressure at the proximal end. A tip is at the distal end and a vent hole is formed in the tip being in connection with the insufflation channel and adapted to expel fluid under pressure to insufflate the abdominal region. The tip is formed of a transparent material to facilitate visualization of the abdominal wall and region. The shaft includes a lumen extending along the axis between the proximal end and the distal end to enable insertion of a laparoscope. The lumen and insufflation channel may be formed as separate channels or as one shared channel.Type: GrantFiled: March 4, 2019Date of Patent: February 16, 2021Assignee: Applied Medical Resources CorporationInventors: Jeremy J.

Patent number: 10765832Abstract: 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 include a combination of flexible and rigid ring-shaped elements assembled along different portions or sections of the tubular structure. In another aspect of the invention, the medical tubing may further comprise a secondary lumen and a pull wire to control the tubular structure. In another aspect of the invention, the ring-shaped elements may vary in diameter and/or composition in different portions or sections of the tubular structure.Type: GrantFiled: April 10, 2018Date of Patent: September 8, 2020Assignee: Applied Medical Resources CorporationInventors: John R.

Patent number: 10568658Abstract: 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: April 17, 2017Date of Patent: February 25, 2020Assignee: Applied Medical Resources CorporationInventors: Henry Kahle, Arkadiusz A.
