20100224668 | Surgical Stapling System - A system is provided for joining two tubular structures by a surgical stapling procedure. The system includes a series of sizers, a specifically designed graft, a loading unit, a wand, a tourniquet, and a stapling instrument. The sizers are for determining the diameter of a target aorta and the availability of a sufficient transected aortic length to perform a stapling procedure. The loading unit holds the graft in position in the body and deploys a circumferential line of staples through the graft and an overlapping end of the aorta. The graft includes a side port by which the loading unit holds the graft during the stapling procedure, and which may be closed once the stapling procedure has been completed. The wand may be used to introduce the loading unit and graft into the body, to position them within the transected aorta, and to hold them in place during the application of the tourniquet. The tourniquet includes a band formed from a flexible material and having a width greater than its thickness so as to facilitate the formation of an annular loop. With the tourniquet holding the aorta and graft in relative overlapping positions, the wand may be removed from the loading unit and the stapling instrument includes a plurality of anvils, which may be closed to form a circle overlying the aorta, and a trigger mechanism for firing the staples. When fired, the staples are deployed radially outward through the graft and aorta, whereupon their free ends are bent inwardly by staple returns on the anvils. As a result, a plurality of staples may be simultaneously deployed quickly and accurately in a circumferential pattern so as to join together two tubular structures. The system may be used in either an open surgical procedure or laparascopically. | 09-09-2010 |
20130060324 | ENDOVASCULAR STAPLER - An endovascular stapler for securing an endograft to a vessel is disclosed. The stapler includes a staple housing adapted for storing at least one staple therein, the staple housing having an exit area for discharge of the at least one staple therethrough, an actuating assembly adapted for discharging the at least one staple through the exit area, and a displacement mechanism in operative association with the staple housing near the exit area. The displacement member is operative for pushing the exit area against the endograft when discharging the at least one staple therethrough. The discharged staple forms a plurality of opposed loops connected by a central element upon discharge. Also disclosed are staples and displacement mechanisms adapted for use with surgical instruments such as the present endovascular staplers. The staples may be formed from memory metal or other metal. The displacement mechanisms disclosed include balloons and rigid offsetting devices. | 03-07-2013 |
20130072883 | Implantable dialysis access port - An implantable access port in accordance with one embodiment of the invention comprises a hollow port casing having a first channel, a second channel and a third channel. A self-sealing insert may be disposed within the third channel. The implantable access port may further comprise a graft having a first branch, a second branch, and a third branch, the first branch extending from the first channel and adapted to be anastomosed to a vessel at a first location, the second branch extending from the second channel and adapted to be anastomosed to a vessel in a second location, the third branch extending at least partially into the third channel, wherein the third branch is disposed between the self-sealing insert and the hollow port casing. Methods for performing medical procedures associated with the implantable access port are also disclosed. | 03-21-2013 |

20110282322 | Hemodialysis Access Needle Assembly System and Method - An access needle assembly for use with implanted hemodialysis access ports is disclosed. In some embodiments, the assembly includes the following: a tubular needle having an internal cavity including an open leading end having a beveled edge and an open trailing end opposite the leading end, the cavity including a side outflow opening adjacent the trailing end; an obturator configured to be removably positioned within the tubular needle; an interface portion including a central cavity so that the interface portion is positioned adjacent the opening, the interface including a flanged portion extending substantially perpendicular from the central cavity and positioned concentrically over the opening; a conduit portion fluidly connected with the cavity via the flanged portion; and a depth block joined with the interface portion below the flanged portion, the depth block including a lower end opposite the interface portion. | 11-17-2011 |
20130060192 | NEEDLE ASSEMBLY - Needle assemblies are disclosed. In some embodiments, the needle assembly includes a main housing including an obturator insertion opening and an opposite needle connection opening, a connector housing configured to engage the main housing, the connector housing including obturator, tubing, and plug openings, a self-sealing plug including a channel, the plug positioned within the connector housing so the channel is aligned with the tubing opening, a needle holder base, and a needle. The connector housing is configured to engage the main housing in first and second positions. The obturator opening is axially aligned with the obturator insertion opening and axially aligned with the needle in the first position. The tubing opening is axially aligned with the obturator insertion opening and in fluid connection with the needle in the second position. | 03-07-2013 |
