Abstract
A dilating device for use in obtaining access to a body organ of a patient comprises, in accordance with the present invention, a plurality of elongate rigid members extending substantially parallel to one another, and an elastic membrane connected to the rigid members for defining a transversely expandable longitudinally extending channel. The rigid members take the form of elongate, substantially cylindrical or conical segments. A needle is inserted through the channel defined by the membrane and the rigid segments. Alternatively, the dilating device is inserted through the needle. Upon expansion of the dilating device, an instrument such as a catheter or endoscope is inserted to implement a surgical or diagnostic procedure.
