Abstract: 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.

Abstract: 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.

Abstract: An implantable access post having a port casing core with an aperture therethrough, a patch associated with the port casing core, the patch adapted to be sewn to a vessel to connect the port casing core to the vessel to permit fluid communication from the vessel through the aperture of the port casing core, and an insert disposed within the aperture of the port casing core, the insert adapted to prevent fluid flow through the aperture. The insert may be self-sealing and may include a valve. The port may also include a port outer casing at least partially surrounding the port casing core and further including an anti-vessel-compression mechanism.

Abstract: A positioning system for use during surgical procedures comprising a belt assembly adapted to be positioned about a bodily surface of a patient. The belt assembly may comprise a single module, or a first module adapted to be attached to a second module. The modules may be adapted to permit attachment of a surgical instrument thereto. The modules may also include cushioned undersides. The system may also comprise a surgical instrument retention system including a saddle adapted to be positioned on a surgical instrument, straps adapted to secure the saddle to the surgical instrument, and a pulley cord coupled to the saddle so as to selectively position the surgical instrument upon movement of the pulley cord. The modules may also include an accessory adapted to fit securely within shaped openings formed therein. The accessory may comprise a base having a locking apparatus for locking a medical device to the base.
