Abstract: A suction cannula, dilator, stapler and staple are provided herein. The suction cannula is concentrically aligned with a puncture site (e.g., puncture in an artery or vein) and provides vacuum about the periphery of the puncture site so that the puncture hole is always located during a medical procedure, and to thereby permit a surgeon to quickly and efficiently close the puncture using, for example, a stapling device. In the preferred embodiment the suction cannula has a tube-in-tube construction having an inner tube and an outer tube where a vacuum can be applied between the tubes. The dilator (and suction cannula) centers around a guide wire (that is already in place within the venous structure) and follows the path of the guide wire to the puncture site. Preferably, the dilator has a tapered tip on the distal end that enters a hole made in the vein or artery. A blood indicator is provided on the proximal end to provide visual feedback when the surgeon is in the artery (i.e., pulsating blood indicates that the tip of the dilator is in the artery). Also preferably, the dilator includes a tapered tip on the distal end that is radially collapsible so that the dilator can be withdrawn from the artery and the suction cannula is thereby permitted to advance over the dilator to the artery wall. The stapler is provided which holds a multi-pronged staple on a shaft at the distal end. The stapler is constructed to slide into the suction cannula (i.e., the inner tube of the cannula) to approach the puncture in the artery, to permit the stapling of the artery. Preferably, the distal end of the stapler includes a T-flange that holds a staple and a crimping mechanism that crimps the staple into the artery, thereby sealing the puncture. The T-flange permits the staple to be held and inserted into the artery wall. An oval hub on the T-flange is provided that mates with an oval hole in the center of the staple. To hold a staple, a staple is placed on the hub and rotated 90 degrees, thereby affixing the staple to the stapler. Once the staple is crimped onto the artery wall, the shaft can be rotated 90 degrees, thereby aligning the oval hub and the oval hole, so that the stapler can be removed. Preferably, the staple includes a plurality of prongs that are inserted into the vascular wall.

Abstract: A hemodialysis port comprising a flexible housing member defining one or more ports. Each port has a selectively-permeable septum member disposed thereon to permit medical devices, for example, Huber needles, sheath and/or dilators to be inserted therein. At the interface between the housing and the septum, a spring member is provided to provide an axial force on the septum which seals the puncture created by the aforementioned medical devices. In one exemplary embodiment, the hemodialysis access port of the present invention is comprised of a plurality of ports designed for multiple hemodialysis treatments over the life of the port. In other exemplary embodiments, the bottom of each port may comprise a needle stop insert formed of, for example, metal, titanium, stainless steel or ceramic.

Abstract translation: 一种血液透析端口，包括限定一个或多个端口的柔性壳体构件。 每个端口具有设置在其上的选择性渗透的隔膜构件，以允许医疗装置，例如Huber针，护套和/或扩张器插入其中。 在壳体和隔膜之间的界面处，提供弹簧构件以在隔膜上提供轴向力，其密封由上述医疗装置产生的穿刺。 在一个示例性实施例中，本发明的血液透析入口端口包括多个端口，其被设计用于端口寿命期间的多次血液透析治疗。 在其他示例性实施例中，每个端口的底部可以包括由例如金属，钛，不锈钢或陶瓷形成的针止动插入件。
