Reporters obtained the following quote from the background information supplied by the inventors: "a. Technical Field
"The instant disclosure relates to medical devices, including handles for elongate medical devices.
"b. Background Art
"It is known to use elongate medical devices, such as, for example, catheters and sheaths or introducers, when performing various therapeutic and/or diagnostic medical procedures on or in various anatomical structures of a patient's body, such as, for example, the heart. Such devices generally include an elongate shaft having a proximal end portion, a distal end portion, a number of electrical and fluid elements, and a handle assembly disposed at the proximal end portion of the shaft. In order to provide access to the electrical and fluid elements in the shaft, the handle assembly generally includes one or more connector ports through which one or more connectors may provide connections to fluid supplies, mapping and navigation systems, and the like.
"In some known medical device handles, a connector may move in a port, and the components on the interior of the handle to which the connector is coupled (such as, for example, a fluid lumen or an electrical wire) may twist or stretch. This movement of a connector and/or interior components may have undesirable effects, such as leakage of irrigation fluid due to crimping of an internal fluid lumen and/or separation of a connector from its connector port.
"The foregoing discussion is intended only to illustrate the present field and should not be taken as a disavowal of claim scope."
In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "To address one or more of the problems set forth above, an embodiment of an elongate medical device handle assembly may comprise a body defining an interior, an exterior, and a connector port. The connector port may extend between the interior and the exterior and may define an axis that extends from the interior to the exterior. The connector port may comprise a portion having a substantially polygonal cross-section taken transverse to the axis.
"A method for manufacturing a medical device handle assembly that addresses one or more of the problems set forth above may include a number of steps. A first step may include providing a handle portion, the handle portion at least partially defining an interior of the handle and having an exterior, the handle portion comprising a connector port extending between the interior and the exterior and defining an axis that extends from the interior to the exterior. The connector port may comprise a substantially polygonal cross-section taken transverse to the axis. A second step may include coupling a connector with the connector port. In an embodiment, the method may further comprise treating the connector port before coupling the connector with the connector port. The treatment may include a plasma treatment and/or an abrasion treatment.
"A method for facilitating access with a medical device handle assembly that addresses one or more of the problems set forth above may include a number of steps. A first step may include constructing a connector port having a polygonal cross-section taken substantially transverse to an axis of the connector port. A second step may include arranging the connector port in a handle portion of the medical device handle assembly to enable access between an interior and exterior of the handle portion along the axis of the connector port. A third step may include facilitating receipt of a connector via the polygonal cross-section of the connector port.
