Abstract
A steerable sheath for a catheter delivery system and associated devices and methods are disclosed. In some embodiments, the catheter delivery system includes a catheter sheath having a steerable distal portion and a flexible elongate member connecting to a steering unit. The flexible elongate member has a central lumen through which a therapeutic or diagnostic device of a first modality can be inserted, used to perform a procedure, and then removed and replaced by a different therapeutic or diagnostic device while the catheter sheath remains substantially at the same location within a patient.
Claims30
A method for directing multiple intravascular devices to a region of interest within a vessel of a patient, the method comprising:
- inserting a catheter sheath including a flexible elongate member having a central lumen situated within the catheter sheath into the patient;
- guiding a steerable distal portion of the catheter sheath to the region of interest utilizing a steering actuator coupled to a steering ring situated within a distal portion of the catheter sheath encircling the central lumen, wherein the steering ring is coupled to a distal end of the flexible elongate member via a coupling tube situated within the catheter sheath so that a proximal side of the coupling tube is positioned within a counterbore formed in the distal end of the flexible elongate member and extends the central lumen and a distal end of the coupling tube abuts a proximal side of the steering ring, the flexible elongate member being spaced proximally from the steering ring by the coupling tube;
- performing a first procedure at the region of interest with a first intravascular device extending into the central lumen of the catheter sheath at least partially received within the distal portion of the catheter sheath distal to the steering ring;
- and
- performing a second procedure at the region of interest with a second intravascular device at least partially received within the distal portion of the catheter sheath, the second procedure being a different modality than the first procedure.
2 more elements
A catheter delivery system comprising:
- a catheter sheath having a steerable distal portion including a steering ring and a coupling tube situated within the catheter sheath and a plurality of steering lines running through a plurality of peripheral lumens of a first flexible elongate member having a central lumen situated within the catheter sheath, the distal ends of the plurality of steering lines being connected to the steering ring in the steerable distal portion of the catheter sheath encircling the central and the proximal ends of the plurality of steering lines being connected to a steering actuator coupled to a housing sized and shaped for handheld use,
- wherein the coupling tube having a proximal end positioned within a counterbore formed in a distal end of the first flexible elongate member for extending the central lumen through the steerable distal portion and a distal end that abuts a proximal side of the steering ring such that the coupling tube proximally spaces the flexible elongate member from the steering ring, and
- wherein the housing includes an opening extending therethrough in communication with the central lumen to allow insertion of intravascular devices of different modalities into the central lumen and removal of the intravascular devices of different modalities from the central lumen, wherein the intravascular devices inserted into the central lumen extend at least partially distal to the steering ring encircling the central lumen.
A catheter delivery system comprising:
- a housing, the housing including a joystick;
- and
- a catheter sheath having a central lumen defined by a first flexible member situated therein, the catheter sheath having a steerable distal portion including a coupling tube and a steering ring situated therein and a plurality of steering lines connected to the joystick at a proximal end and to the steering ring at a distal end, the steering ring being positioned within the steerable distal portion encircling the central lumen to allow an intravascular devices inserted into the central lumen to extend at least partially beyond the steering ring for application of a procedure by the intravascular device, wherein the catheter sheath further comprises a coupling tube having a proximal end positioned within a counterbore formed in a distal end of the first flexible member and a distal end of the coupling tube that abuts a proximal end of the steering ring such that the coupling tube proximally spaces the flexible elongate member from the steering ring and extends the central lumen through the steerable distal portion.
