Abstract
A connector stent of adjustable length is provided for draining fluid through a biological passage. The connector stent comprises an elongated tubular member and a connector. A retaining means is disposed at one end of the elongated tubular member, the other end being straight. A retaining means is disposed at one end of the connector, the other end being adapted to engage the straight end of the elongated tubular member. The straight end of the elongated tubular member may be cut to a desired length before engaging the connector so that the length of the connector stent corresponds to the length of the fluid passageway to be drained.
Claims29
A connector stent comprising:
- an elongated tubular member having a wall with apertures therethrough, and comprising a retaining means and an essentially straight custom trimmed portion terminating in an axial opening;
- and
- a connector comprising a retaining means and an adapter means that is fixedly secured within said axial opening of said straight custom trimmed portion.
A method for providing drainage of a biological fluid passage through a connector stent comprising the steps of:
- measuring the length of said fluid passage;
- custom trimming an essentially straight portion of said connector stent to a length corresponding to said fluid passage length such that said straight portion terminates in an axial opening;
- fixedly securing a connector within said axial opening of said custom trimmed straight portion;
- and
- inserting said connector stent to a predetermined position within said fluid passage.
A kit for providing drainage through a biological fluid passage comprising:
- a. a guidewire;
- b. an elongated tubular member having a wall with apertures therethrough and comprising a retaining means and an essentially straight portion to be custom trimmed and terminate in an axial opening;
- and
- c. a connector comprising a retaining means and an adapter means for fixedly securing within said axial opening of said straight custom trimmed portion.
A kit for providing drainage through a biological fluid passage comprising:
- a. a guidewire;
- and
- b. a ureteral connector stent comprising an elongated tubular member and a connector, said elongated tubular member comprising a retaining means and a straight tube and wherein said connector comprises a retaining means and an adapter means.
A ureteral stent for customized use in the ureter comprising an elongated tubular member with apertures therethrough having an essentially straight custom trimmed portion terminating in an axial opening at one end and a curved body retaining portion at the other end thereof, a shortened tubular member with apertures therethrough having a connector adapter means at one end and a curved body retaining portion at the other end thereof, said connector adapter means being fixedly secured within said axial opening of said straight trimmed portion to form the customized stent after said straight portion has been trimmed to the desired length.
A kit for providing drainage through a biological fluid passage comprising:
- (a) a guide wire;
- and
- (b) a ureteral connector stent comprising an elongated tubular member having a retaining means, a connector having a retaining means, and means for adjusting the length of said stent to accommodate various anatomies without deforming said retaining means.
