Abstract
An example catheter includes a tubular body portion and a cuff. The tubular body portion has a proximal end portion and a distal end portion. The distal end portion defines a distal face of the tubular body portion. The cuff is mounted to the distal end portion and defines a distal face of the cuff. In certain embodiments, the tubular body portion terminates within the cuff such that the distal face of the body portion is positioned proximally of the distal face of the cuff. In certain embodiments, a pocket is formed between the cuff and the body portion. In certain embodiments, the body portion is more rigid than the cuff.
Claims20
A catheter, comprising:
- a tubular body portion having a proximal end portion and a distal end portion, wherein the distal end portion defines a distal body portion face of the tubular body portion;
- a cuff mounted to the distal end portion and defining a distal cuff face of the cuff, wherein the cuff comprises an opening that is defined at least in part by a wall of the cuff;
- and
- a pocket positioned within the opening and having an open proximal end, wherein the pocket comprises a flap having a periphery, wherein a first portion of the periphery is secured to the wall, and wherein a second portion of the periphery is not secured to the wall to thereby define the open proximal end;
- wherein the tubular body portion terminates within the cuff such that the distal body portion face is positioned proximally of the distal cuff face,
- wherein an offset distance is defined between the distal body portion face and the distal cuff face;
- and
- wherein the cuff has a longitudinal length, and the offset distance is between 40% of the longitudinal length of the cuff and 60% of the longitudinal length of the cuff.
A catheter defining an evacuation passage, the catheter comprising:
- a tubular body portion defining a proximal outlet of the evacuation passage;
- and
- a cuff mounted to a distal end portion of the tubular body portion, wherein the cuff defines a distal inlet of the evacuation passage, wherein the tubular body portion extends into an opening that extends through the cuff, and wherein the opening is defined at least in part by a wall of the cuff;
- and
- a flap having a periphery, wherein a first portion of the periphery is secured to the wall, and wherein a second portion of the periphery is not secured to the wall to thereby define an open proximal end of a pocket;
- wherein the proximal outlet has a first diameter;
- wherein the distal inlet has a second diameter greater than the first diameter, wherein an offset distance is defined between a face of the distal end portion of the tubular body portion and a distal cuff face;
- and
- wherein the cuff has a longitudinal length and the offset distance is between 40% of the longitudinal length of the cuff and 60% of the longitudinal length of the cuff.
A catheter, comprising:
- a tubular body portion having a proximal end portion and a distal end portion;
- a cuff defining an opening having a proximal portion and a distal portion, wherein the distal end portion of the tubular body portion is received in the proximal portion;
- and
- a pocket positioned between the tubular body portion and the cuff, wherein the pocket is defined by a flap having an outer periphery, wherein a first portion of the outer periphery is secured to a wall of the opening, and wherein a second portion of the periphery is not secured to the wall such that the pocket is defined with an open proximal end;
- wherein the tubular body portion has a greater rigidity than the cuff,
- wherein an offset distance is defined between a distal body portion face defined by the distal end portion of the tubular body portion and a distal cuff face;
- and
- wherein the cuff has a longitudinal length and the offset distance is between 40% of the longitudinal length of the cuff and 60% of the longitudinal length of the cuff.
