Abstract
A catheter system 1 has an internal reception space for an embolic protection filter 10 to enable the filter 10 to be transported through a vasculature 20 and a treatment means such as a stent 15 to facilitate treatment. The catheter system may, in some configurations be used for retrieval of a filter 10 and stenting of a lesion with a stent 15. The procedure may also involve post dilitation using an on-board balloon 16.
Claims85
A catheter having an internal reception space for receiving an embolic protection filter for transporting the filter through a vasculature;
- and
- the catheter comprising a treatment device to facilitate treatment of a site in a vasculature.
A delivery and deployment catheter system comprising:—
- a filter catheter section;
- a filter mounted in the filter catheter section, the filter being movable on release from the filter catheter section from a collapsed delivery configuration to an expanded deployment configuration,
- a stent catheter section;
- a stent mounted in the stent catheter section, the stent being movable on release from the stent catheter section from a retracted delivery configuration to an expanded deployment configuration;
- and
- having a guidewire lumen for receiving a guidewire through the catheter sections;
- the stent catheter section and associated stent being movable along the guidewire independently of the deployed filter for sequential deployment of the filter and stent.
A catheter system comprising a filter delivery catheter and a treatment device delivery catheter, the filter delivery catheter comprising a filter retaining sheath and a shaft extending from the sheath, the treatment device delivery catheter comprising a treatment device retaining sheath and a shaft extending from the sheath, the treatment device delivery catheter shaft being extendable through the filter delivery catheter.
A method for carrying out a procedure at a treatment site in a vasculature comprising the steps of:—
- providing an embolic protection device;
- deploying the embolic protection device distal of the treatment site;
- providing a procedural catheter comprising a tubular member having a distal space housing a medical device;
- advancing the procedural catheter to the treatment site;
- deploying the medical device from the procedural catheter at the treatment site;
- and
- retrieving the embolic protection device into the procedural catheter.
A method for carrying out a procedure at a treatment site in a vasculature comprising the steps of:—
- providing a catheter comprising a tubular member having a distal space, the distal space comprising a first portion and a second portion, the first portion being adjacent to and distal of the second portion;
- providing a treatment device loaded into the second portion of the distal space of the catheter;
- providing an embolic protection device loaded into the first portion of the distal space of the catheter;
- the embolic protection device having a collapsed configuration for transport through the vasculature and an expanded deployed configuration for collecting emboli released during a procedure;
- advancing the catheter to a treatment site in the vasculature;
- deploying the embolic protection device from the first portion of the distal space in the catheter, the deployed filter taking up an expanded emboli-collecting configuration distal to the treatment location;
- and
- deploying the treatment device from the second portion of the distal space in the catheter to carry out a procedure at the treatment site.
A method for carrying out a procedure at a treatment site in a vasculature comprising the steps of:—
- providing a catheter system comprising a filter delivery catheter and a treatment device delivery catheter, the filter delivery catheter comprising a filter retaining sheath and a shaft extending from the sheath, the treatment device delivery catheter comprising a treatment device retaining sheath and a shaft extending from the sheath, the treatment device delivery catheter shaft extending through the filter delivery catheter sheath and shaft;
- providing a treatment device loaded into the treatment device delivery sheath;
- providing an embolic protection device loaded into the filter sheath, the embolic protection device having a collapsed configuration for transport through the vasculature and an expanded deployed configuration for collecting emboli released curing a procedure;
- advancing the catheter system to a treatment site in the vasculature;
- deploying the embolic protection device from the filter sheath, the deployed filter taking up an expanded emboli-collecting configuration;
- and
- deploying the treatment device from the sheath of the treatment device delivery catheter.
