Abstract
A medical instrument is provided including a device having an expandable portion and a transitional portion. The transitional portion has a spiral cut on the outer surface, and is aligned with the distal portion of a catheter. The transitional portion may be secured to the catheter by a sleeve which is coupled to both the catheter and the transitional portion. Alternatively, the portion of the transitional portion having the spiral cut may be embedded within the catheter.
Claims20
A medical instrument, comprising:
- a device comprising a transitional portion and a second portion, the transitional portion comprising a spiral cut arranged through an outer surface of the transitional portion;
- a catheter comprising at least one lumen, wherein a distal portion of the catheter is aligned with the transitional portion, and wherein the distal portion is positioned at least partially within the transitional portion;
- and
- a sleeve positioned over the transitional portion and the catheter, which is coupled to the catheter and coupled to the transitional portion, wherein the sleeve secures the transitional portion of the device to the distal portion of the catheter.
A medical instrument, comprising:
- a device comprising a transitional portion and an expandable portion, the transitional portion comprising a spiral cut arranged through an outer surface of the transitional portion;
- and
- a catheter comprising a wall and at least one lumen, wherein a distal portion of the catheter is aligned with the transitional portion, and wherein at least the portion of the transitional portion comprising the spiral cut is embedded within the wall of the catheter.
A medical instrument, comprising:
- a device comprising a transitional portion and an expandable portion, the transitional portion comprising a spiral cut arranged through an outer surface of the transitional portion;
- a catheter, wherein a distal portion of the catheter is aligned with the transitional portion, and wherein the distal portion is positioned at least partially within the transitional portion;
- and
- a sleeve having an inner surface which is coupled to an outer surface of the distal portion of the catheter, wherein the transitional portion is embedded within the sleeve so that at least a portion of the sleeve passes through the spiral cut of the transitional portion.
