Abstract
An elongate catheter shaft is provided, having a side port aperture through a side wall of the catheter shaft between proximal and distal ends of the shaft. The side port aperture is open to a lumen. Embodiments of the present invention are directed to attached structures disposed in the side port aperture. The attached structures described herein are directed to biasing the catheter shaft in the region of a side port aperture in a straight or curved configuration that resists undesired flexure in the region of the side port aperture and to providing ease of wire guide passage.
Claims22
A catheter device comprising an elongate shaft,
- said elongate shaft comprising:
- a proximal end;
- a distal end;
- a first lumen extending through at least a portion of the shaft and defined by a wall;
- an aperture through the wall, open to the first lumen;
- said aperture disposed between the proximal and distal ends;
- and
- an overlay disposed at least partially in the aperture, the overlay including an access port open to the first lumen, said access port being configured for passage of a wire guide therethrough.
A method of providing a side port aperture with a support structure, comprising the steps of:
- providing an elongate catheter shaft, the catheter shaft comprising a lumen therethrough and a wall surrounding the lumen;
- providing a side port aperture by removing a portion of wall material sufficient to provide access to the lumen;
- providing a support structure, the support structure comprising
- a body configured to fit into at least a portion of the side port aperture;
- a fenestration through the body, the fenestration providing an angled path from an upper side of the body therethrough to the lower side;
- and
- attaching the support structure to the catheter shaft such that at least a portion of the support structure is disposed in the side port aperture and the fenestration of the support structure provides an opening to the lumen, said fenestration being smaller than the side port aperture.
A catheter device comprising an elongate shaft,
- said elongate shaft comprising:
- a proximal end;
- a distal end;
- a first lumen extending through at least a portion of the shaft and defined by a wall;
- an aperture through the wall, open to the first lumen;
- said aperture disposed between the proximal and distal ends;
- an insert disposed at least partially in the aperture, the insert comprising an access port open to the first lumen and at least a portion of the insert extending into the first lumen, said access port being configured for passage of a wire guide therethrough.
A catheter device comprising an elongate shaft,
- said elongate shaft comprising:
- a proximal end;
- a distal end;
- a first lumen extending through at least a portion of the shaft and defined by a wall;
- an aperture through the wall, open to the first lumen;
- said aperture disposed between the proximal and distal ends;
- an attachment disposed at least partially in the aperture, the attachment comprising an access port open to the first lumen, said access port being configured for passage of a wire guide therethrough.
