Abstract
Medical device delivery systems and methods for making and using medical device delivery systems are disclosed. An example medical device delivery system may include an outer sheath. An inner catheter may be disposed within the outer sheath. The inner catheter may have a distal end. A tube extension may be coupled to the distal end of the inner catheter and may extend distally therefrom. The tube extension may be configured to shift between a first elongated configuration and a second shortened configuration.
Claims20
A medical device delivery system, comprising:
- an outer sheath;
- an inner catheter disposed within the outer sheath, the inner catheter having a distal end;
- a tube extension coupled to the distal end of the inner catheter and extending distally therefrom;
- and
- wherein the tube extension is configured to shift between a first elongated configuration and a second shortened configuration.
The system of claim 7, wherein at least some of the slots are open when the tube extension is in the elongated configuration and wherein at least some of the slots are closed when the tube extension is in the shortened configuration.
A medical device delivery system, comprising:
- an outer sheath;
- an inner catheter disposed within the outer sheath, the inner catheter having a distal portion;
- a valve implant releasably coupled to the distal portion of the inner catheter;
- a tube extension coupled to the distal portion of the inner catheter and extending distally therefrom;
- and
- wherein the tube extension has a distal end that is free of a nose cone.
A medical device delivery system, comprising:
- an outer sheath having a distal portion;
- wherein the distal portion is configured to shift between a tapered configuration where the distal portion is deflected radially inward and an open configuration;
- an inner catheter disposed within the outer sheath, the inner catheter having a distal end;
- and
- a valve implant releasably coupled to the distal end of the inner catheter.
