Body Cavity Dilation System

摘要

A system for dilating a body cavity with a device including a series of elongated members, each having a central channel and increasing outer diameters where the members are positioned one over the other such that the members are advanced into the body cavity to incrementally dilate the body cavity. The central channels of each member allow for various procedures to be performed including, for example, the application of wireless energy (e.g., ultrasonic) to the body cavity, the introduction of an irrigating fluid and aspiration from the body cavity, and the introduction of a drug to the body cavity.

主权项

1. A device for dilating a body cavity comprising:
a first member including:
a first elongated body portion with a first proximal end and a first distal end defining a first length, the first distal end being deflectable, said first elongated body portion defining a first outside diameter (OD) and having a first channel therein extending from the first proximal end to the first distal end, the first channel defining a first inside diameter (ID);a handle coupled to the first proximal end, said handle including a deflection control for deflection of the first distal end; a second member including:
a second elongated body portion with a second proximal end and a second distal end defining a second length, the second distal end being deflectable, said second elongated body portion defining a second OD and having a second channel therein extending from the second proximal end to the second distal end, the second channel defining a second ID; said second ID being larger than the first OD such that said first member is longitudinally moveable within of the second channel; a third member including:
a third elongated body portion with a third proximal end and a third distal end defining a third length, the third distal end being deflectable, said third elongated body portion defining a third OD and having a third channel therein extending from the third proximal end to the third distal end, the third channel defining a third ID; said third ID being larger than the second OD such that said second member is longitudinally moveable within of the third channel.
