20090118675 | ELONGATE MEDICAL DEVICE WITH A SHAPEABLE TIP - Medical devices and methods for manufacturing and using medical devices. An example medical device includes a core member, a tubular member coupled to the core member, and a tip member coupled to the tubular member. The tubular member may include a first section having a first outer diameter and a second section having a second outer diameter that is smaller than the first outer diameter. | 05-07-2009 |
20090221969 | DEVICE AND MEDICAL INSTRUMENT FOR PREVENTING EXCESSIVE INSERTION OF A ROD-LIKE MEMBER - A device for preventing excessive insertion of a rod-like member when the rod-like member is inserted into a gastrostomy catheter, and to a medical instrument provided with the same. The device comprises a reference position establishment part which can be installed at a base end opening side of the gastrostomy catheter, a mobile part which can be fixed to the endoscope, and a linking part. The linking part can change the gap between the reference position establishment part and the mobile part within a range no greater than a set length, and links the reference position establishment part and the mobile part. Furthermore, a bending instrument for bending the tip end of the endoscope when said tip end portion projects a prescribed length outwards from a through-hole of a stomach-internal fixed part is fitted to the tip end of the endoscope. | 09-03-2009 |
20110196307 | SURGICAL ACCESS APPARATUS AND METHOD - A trocar system for providing access across a body wall includes a trocar and an anchor provided in the form of a first helix. The anchor is adapted for placement in an operative position wherein the anchor extends at least partially through the body wall. A second helix formed on the trocar is size and configured to engage the first helix of the anchor so that rotation of the trocar relative to the anchor moves the second helix along the first helix. In this manner, the trocar is drawn into the anchor as it moves into the body wall. A proximal force applied to the anchor resists tenting of the abdominal wall. The anchor also holds the layers of the body wall together thereby resisting peritoneal separation. | 08-11-2011 |
20130102967 | Magnetic Trocar System - Systems and methods for using a trocar system are disclosed. The system generally comprises a trocar, a magnet, and a magnetizable cannula. The trocar has a first end and a second end. The magnetizable cannula has a central opening sized to receive the trocar. The magnet is positioned adjacent the second end of the trocar and its magnetic field releasably secures the magnetizable cannula in a position adjacent the second end of the trocar. | 04-25-2013 |
604170020 | Obturator or stylet | 5 |
20080269684 | FORMABLE STYLET - A formable stylet | 10-30-2008 |
20090054841 | System and Method for Providing an Obturator for Enhanced Directional Capabilities in a Vascular Environment - An apparatus for assisting in a vascular procedure includes an obturator operable to be mounted on a medical device to guide the medical device into a targeted region, whereby the obturator is substantially blunt such that it exhibits a snag-resistant property. In alternative embodiments, the apparatus includes an interface element operable to be used in conjunction with the obturator and to engage an interface of the targeted region such that pressure is maintained within the targeted region. The interface element includes a convex portion that operates to seat the interface element at a selected location. The interface element is substantially transparent and includes a magnification element that magnifies materials underlying the interface element. In other embodiments, the apparatus includes a tray operable to provide a mold for forming the obturator, which may comprise a gas, water, sugar, clotted blood, a gelatinous material, a protein, a saline solution, or dry-ice. | 02-26-2009 |
20100298776 | BLUNT TIP OBTURATOR - A surgical obturator comprising an elongate 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 having a conical surface forming proximally into an outer surface, the outer surface extending distally to a blunt point and having a pair of side sections. The side sections extend from the blunt point radially outwardly with progressive positions proximally along the axis. The conical surface facilitates insertion of the obturator with a reduced penetration force and minimizes tenting of the body wall. The conical surface further facilitates separation of different layers of the body wall and provides proper alignment of the tip between the layers. The surgical obturator may be constructed from a disposable or reusable material such as a metal or an autoclavable polymer. While certain embodiments have been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope thereof as defined by the following claims. | 11-25-2010 |
20120109064 | PORT FIXATION WITH INTERLOCKING STRUCTURE - The present disclosure relates to a surgical access system that includes a cannula assembly adapted for removable positioning within a percutaneous tissue tract, and an obturator assembly removably positionable within the cannula assembly. The cannula assembly includes a cannula housing, a cannula sleeve, and first engagement structure, and the obturator assembly includes an obturator housing, an obturator sleeve, and second engagement structure. The first engagement structure and the second engagement structure are correspondingly dimensioned such that rotation of the obturator assembly in a first direction effectuates corresponding rotation of the cannula assembly to facilitate advancement of the cannula assembly through tissue. | 05-03-2012 |
20150105728 | BLADELESS OPTICAL OBTURATOR - 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. The side sections include a distal portion and a proximal portion, the distal portion of the side sections being twisted radially with respect to the proximal portion of the side sections. The intermediate section includes a distal portion and a proximal portion, the distal portion of the intermediate section being twisted in a first radial direction and the proximal portion of the intermediate section being twisted in a second radial direction opposite the first radial direction. | 04-16-2015 |
