Abstract
An apparatus for treating a wall of a body cavity comprising an elongate probe member having a distal extremity with an outer surface and at least one recess opening onto the outer surface. When a suction source is coupled to the apparatus, a suction is created in the recess to draw a portion of the wall into the recess. A needle is slidably disposed in the elongate probe member and actuatable from outside the body for movement from a retracted position to an extended position in which the distal end portion of the needle extends into the recess whereby the needle can be extended into the portion of the wall drawn into the recess.
Claims19
An apparatus for use with a suction source to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity comprising an elongate probe member having proximal and distal extremities, the elongate probe member having a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body, the distal extremity of the elongate probe member having an outer surface and being provided with at least one recess opening onto the outer surface and an internal passageway communicating with the recess whereby when the suction source is coupled to the apparatus a suction is created in the recess by means of the passageway to draw the portion of the wall into the recess, a needle slidably disposed in the elongate probe member and having a distal end portion, the needle being actuatable from outside the body for movement from a retracted position in which the distal end portion of the needle is out of the recess to an extended position in which the distal end portion of the needle extends into the recess whereby the needle can be extended into the portion of the wall drawn into the recess.
An apparatus for use with a suction source to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity comprising an elongate first member having proximal and distal extremities, the elongate first member having a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body, an elongate second member slidably mounted on the elongate first member and having proximal and distal extremities, the elongate second member having a length so that when the distal extremity of the elongate second member is in the vicinity of the portion of the wall the proximal extremity of the elongate second member is outside of the body, the distal extremity of die elongate second member having an outer surface and being provided with at least one recess opening onto the outer surface whereby when the suction source is coupled to the apparatus a suction is created in the recess to draw the portion of the wall into the recess, a needle slidably disposed in the elongate second member and having a distal end portion, the needle being actuatable from outside the body for movement from a retracted position in which the distal end portion of the needle is out of the recess to an extended position in which the distal end portion of the needle extends into the recess whereby the needle can be extended into the portion of the wall drawn into the recess.
An apparatus to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity with a suction source and an elongate first member having proximal and distal extremities and a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body and with a needle having a distal portion comprising an elongate second member having proximal and distal extremities, the elongate second member having a length so that when the distal extremity of the elongate second member is in the vicinity of the portion of the wall the proximal extremity of the elongate second member is outside of the body, the elongate second member having a first passageway accessible from its proximal extremity adapted for slidably receiving the elongate first member, the distal extremity of the elongate second member having an outer surface and being provided with at least one recess opening onto the outer surface whereby when the suction source is coupled to die apparatus a suction is created in the recess to draw the portion of the wall into the recess, the elongate second member being provided with a second passageway extending from the proximal extremity of the elongate second member to the recess adapted for slidably receiving the needle whereby the needle is actuatable from outside the body for movement from a retracted position in which the distal end portion of the needle is out of the recess to an extended position in which the distal end portion of the needle extends into the recess and thus into the portion of the wall drawn into thy recess.
An apparatus for treating a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity with a suction source and an elongate member having proximal and distal extremities and with a needle slidably disposed in the elongate member and actuatable from the proximal extremity of the elongate member comprising an end piece and means adapted to mount the end piece on the distal extremity of the elongate member, the end piece having an outer surface and being provided with at least one recess opening onto the outer surface and an internal passageway communicating with the recess whereby when the suction source is coupled to the apparatus so as to communicate with the passageway a suction is created in the recess to draw the portion of the wall into the recess, the end piece permitting the needle to extend into the recess whereby the needle can be extended into the portion of the wall drawn into the recess.
