The present specification discloses a disposable tubing joint connector system which connects a tubing set and an endoscope. The connector embodiments disclosed herein include dual o-ring seals, in two separate channels, that enable an efficient and leak proof connection between two ports of an endoscope and corresponding flexible tubing.

Connector for use with endoscope

A brachytherapy packaging system is disclosed including an inner tray containing a plurality of recesses, each recess for holding a strand of linked radiological seeds separated by spacers. An inner tray cover may also contain a plurality of recesses that coincide with the recesses of the inner tray when placed over the inner tray. The inner tray and inner tray cover may be supported by and enclosed in a container made out of a metal such as pewter. A retainer may also be supportable on the top of the container, shaped for holding a forceps or tweezers. An outer tray may be used for supporting and enclosing the container and optional retainer. The outer tray may be sealed with a removable sheet adhesively attached to a rim of the outer tray. Different configurations of the inner tray and inner tray cover may be used for different packaging configurations.

Packaging system for brachytherapy devices

A urethral support system is described, including an introducer device and tissue implant. The introducer device may include a needle with multiple curves, some of the curves having multiple radii. A sheath assembly may be utilized to assist the passing of the tissue implant through a patient's tissue. The sheath assembly may include connectors configured to connect the sheath assembly to an end of the needle and a tab configured to detachably couple sheath sides over the tissue implant.

Urethral support system

A brachytherapy needle for delivering radioactive seeds into the body of a patient comprises a tube into which the radioactive seeds and intervening spacers are loaded. The tube is telescopically disposed within a cutting cannula and is substantially longer than the cannula such that the cannula can be withdrawn over the tube, leaving the forward end of the tube exposed within the tissues of the patient. When the cannula is retracted, the seeds within the tube can be visualized using conventional medical imaging technology. The tube of the disclosed embodiment includes a deformable constriction which normally retains the seeds within the lumen of the needle but which deforms to permit the seeds to pass when subjected to a predetermined force. The tube of the disclosed needle has a low-friction exterior surface to prevent tissue from being displaced as the device is withdrawn. In yet another aspect the cannula and telescoping hollow tube are dimensioned such that when the cannula is withdrawn with respect to the tube, the blunt forward edge of the tube extends beyond the cutting edge of the hollow cannula to prevent accidental needle sticks.

Needle for implanting brachytherapy seeds

A brachytherapy needle comprises a hollow cannula defining a lumen through which radioactive seeds are delivered. A push stylet is telescopically received within the hollow cannula for advancing the radioactive seeds through the lumen of the cannula. The hollow cannula has a window formed in a side wall through which at least a portion of the lumen can be visualized. In the preferred embodiment the window comprises a slot formed in the side wall of the cannula through which radioactive seeds and intervening spacers can be viewed. Also in the preferred embodiment, a transparent covering, advantageously a sleeve of transparent, heat-shrinkable plastic, is disposed over the slot to prevent tissue from lapsing into the slot during implantation of the seeds.
