1. A medical device for the treatment of a bodily passage, said medical device comprising: an elongate member having a proximal portion and a shaft extending distally from the proximal portion, the proximal portion having a first outside diameter, the shaft having a first proximal end attached to the proximal portion, and a first distal end, the shaft having a second outside diameter that is less than the first outside diameter; an intermediate member releasably disposed on the shaft and having a second proximal end, a second distal end, an intermediate member body, and a third outside diameter that is greater than the first outside diameter of the proximal portion, the intermediate member body defining a first intermediate member opening on the second proximal end, a second intermediate member opening on the second distal end, and an intermediate member lumen extending from the first intermediate member opening to the second intermediate member opening, the intermediate member lumen having an inside diameter that is less than the first outside diameter of the proximal portion; and a tubular member releasably disposed on the shaft distal to the intermediate member, the tubular member separable from the intermediate member and having a third proximal end, a third distal end, and a tubular member body defining a first tubular member opening on the third proximal end, a second tubular member opening on the third distal end, and a tubular member lumen extending from the first tubular member opening to the second tubular member opening, wherein the tubular member body defines a passageway that extends through the tubular member body and provides access to the tubular member lumen, wherein the tubular member has a frustoconical proximal portion that tapers from the third proximal end toward the third distal end; wherein the tubular member lumen has a frustoconical proximal portion that tapers from the third proximal end toward the third distal end; wherein the intermediate member body defines a first surface, a second surface, a frustoconical protuberance, and a support post, the first surface disposed on the second proximal end and opposably facing the second surface, the frustoconical protuberance extending distally from the second surface and tapering from the second surface toward the second distal end, the support post extending distally from the frustoconical protuberance to a support post end; wherein the frustoconical protuberance is disposed within the frustoconical proximal portion of the tubular member lumen; and wherein the support post is disposed within the passageway defined by the tubular member body. 2. A medical device for the treatment of a bodily passage, said medical device comprising: an elongate member having a proximal portion and a shaft extending distally from the proximal portion, the proximal portion having a first outside diameter, the shaft having a first proximal end attached to the proximal portion, a tapered first distal end, and a length extending from the first proximal end to the first distal end, the shaft having a second outside diameter that is less than the first outside diameter; an intermediate member releasably disposed on the shaft and having a second proximal end, a second distal end, an intermediate member body, and a third outside diameter that is greater than the first outside diameter of the proximal portion, the intermediate member body defining a first intermediate member opening on the second proximal end, a second intermediate member opening on the second distal end, and an intermediate member lumen extending from the first intermediate member opening to the second intermediate member opening, the intermediate member lumen having an inside diameter that is less than the first outside diameter of the proximal portion; and a tubular member releasably disposed on the shaft distal to the intermediate member, the tubular member separable from the intermediate member and having a third proximal end, a tapered third distal end, a length extending from the third proximal end to the third distal end, and a tubular member body defining a first tubular member opening on the third proximal end, a second tubular member opening on the third distal end, and a tubular member lumen extending from the first tubular member opening to the second tubular member opening, the length of the tubular member being less than the length of the shaft; wherein the third distal end of the tubular member is disposed proximal to the first distal end of the elongate member, wherein the tubular member body defines a passageway that extends through the tubular member body and provides access to the tubular member lumen, wherein the tubular member has a frustoconical proximal portion that tapers from the third proximal end toward the third distal end; wherein the tubular member lumen has a frustoconical proximal portion that tapers from the third proximal end toward the third distal end; wherein the intermediate member body defines a first surface, a second surface, a frustoconical protuberance, and a support post, the first surface disposed on the second proximal end and opposably facing the second surface, the frustoconical protuberance extending distally from the second surface and tapering from the second surface toward the second distal end, the support post extending distally from the frustoconical protuberance to a support post end; wherein the frustoconical protuberance is disposed within the frustoconical proximal portion of the tubular member lumen; and wherein the support post is disposed within the passageway defined by the tubular member body. 3. A medical device for the treatment of a bodily passage, said medical device comprising: an elongate member having a proximal portion and a shaft extending distally from the proximal portion, the proximal portion having a first outside diameter, the shaft having a first proximal end attached to the proximal portion, a tapered first distal end, and a length extending from the first proximal end to the first distal end, the shaft having a second outside diameter that is less than the first outside diameter;an intermediate member releasably disposed on the shaft and having a second proximal end, a second distal end, an intermediate member body, and a third outside diameter that is greater than the first outside diameter of the proximal portion, the intermediate member body defining a first intermediate member opening, a second intermediate member opening, an intermediate member lumen, a first surface, a second surface, a frustoconical protuberance, and a support post, the first intermediate member opening defined on the second proximal end, the second intermediate member opening defined on the second distal end, the intermediate member lumen extending from the first intermediate member opening to the second intermediate member opening, the intermediate member lumen having an inside diameter that is less than the first outside diameter of the proximal portion, the first surface disposed on the second proximal end and opposably facing the second surface, the frustoconical protuberance extending distally from the second surface and tapering from the second surface toward the second distal end, the support post extending distally from the frustoconical protuberance to a support post end; anda tubular member releasably disposed on the shaft distal to the intermediate member, the tubular member separable from the intermediate member and having a third proximal end, a tapered third distal end, a length extending from the third proximal end to the third distal end, a frustoconical proximal portion that tapers from the third proximal end toward the third distal end, and a tubular member body defining a first tubular member opening on the third proximal end, a second tubular member opening on the third distal end, a tubular member lumen extending from the first tubular member opening to the second tubular member opening, and a passageway extending through the frustoconical proximal portion and providing access to the tubular member lumen, the tubular member lumen having a frustoconical proximal portion that tapers from the third proximal end toward the third distal end, the length of the tubular member being less than the length of the shaft;wherein the third distal end of the tubular member is disposed proximal to the first distal end of the elongate member;wherein the frustoconical protuberance is disposed within the frustoconical proximal portion of the tubular member lumen; andwherein the support post is disposed within the passageway defined by the tubular member body.
