Abstract
Discussed herein are various embodiments related to a catheter assembly. The catheter assembly can include a catheter body extending between a proximal portion and a distal portion. The catheter body can include a sleeve and a hypotube, connected by at least one bond site, and separated by a floating gap. The hypotube can include at least one flow opening extending from the hypotube lumen to a stagnation zone, configured to permit flow between the stagnation zone and the hypotube lumen.
Claims29
A catheter assembly comprising:
- a catheter body extending between a proximal portion and a distal portion, the catheter body including:
- a sleeve extending between the proximal and distal portions, wherein the sleeve includes a sleeve lumen;
- a hypotube having a hypotube lumen, the hypotube extends between the proximal and distal portions and is received within the sleeve lumen;
- at least one bond site connecting the sleeve to the hypotube, wherein the hypotube and the sleeve are spaced forming a floating gap distal to the at least one bond site, and
- wherein the hypotube includes at least one flow opening extending from the hypotube lumen to the floating gap, and the at least one flow opening is configured to permit flow between the floating gap and the hypotube lumen;
- wherein the sleeve includes at least one floating segment and one or more bond sites along the catheter body, wherein the at least one floating segment of the sleeve is moveable relative to the hypotube, and the one or more bond sites of the floating sleeve are interconnected with the hypotube.
3 more elements
A catheter assembly comprising:
- a catheter body extending between a proximal portion and a distal portion, the catheter body including:
- a hypotube extending between the proximal and distal portions,
- a plurality of flow openings on the hypotube, wherein the plurality of flow openings are situated on the hypotube in a stagnation zone;
- and
- a sleeve coupled around the hypotube and extending between the proximal and distal portions, the sleeve coupled to the hypotube by at least one bond site, wherein the sleeve is spaced from the hypotube by a floating gap;
- wherein the plurality of flow openings are configured to allow flow between the hypotube and the floating gap in the stagnation zone;
- wherein the sleeve includes at least one floating segment and one or more bond sites along the catheter body, wherein the at least one floating segment of the sleeve is moveable relative to the hypotube, and the one or more bond sites of the floating sleeve are interconnected with the hypotube;
- and
- a balloon fluidly connected to the distal portion of the catheter body, the balloon configured to be inflated and deflated by movement of fluid through the catheter body, wherein the plurality of flow openings allow for fluid through the stagnation zone during inflation and deflation of the balloon.
