CATHETER WITH CATHETER TIP AND RELATED METHODS

摘要

An elongate catheter tip may be coupled to an elongate catheter body adjacent a distal end of the catheter body. To couple a catheter tip to a catheter body, a proximal portion of the catheter tip may (1) be disposed between a first elongate member and an second elongate member and (2) be subsequently fused to the second elongate member and the first elongate member. The resulting catheter and catheter tip may, among other functions, facilitate the measurement of differences in fluid pressure and/or facilitate the delivery of fluid or medical devices during a medical procedure.

主权项

1. A catheter comprising:
an elongate catheter body, comprising:
a distal end;a first elongate member; anda second elongate member that is at least partially disposed within the first elongate member; an elongate catheter tip coupled to the first elongate member and the second elongate member adjacent the distal end of the elongate catheter body, the elongate catheter tip comprising a proximal portion disposed between the first elongate member and the second elongate member such that the proximal portion of the catheter tip is both disposed around a portion of the second elongate member and disposed within a distal portion of the first elongate member; a first lumen extending through both the second elongate member and the elongate catheter tip; and a second lumen comprising a first portion, the first portion of the second lumen disposed proximal of the catheter tip and between the first elongate member and the second elongate member.
