Catheters that includes inner and outer elongate shafts, each of which is secured relative to an end of an inflatable member. Balloon bonding locations may be disposed radially inward relative to an outer dimension of the outer elongate shaft.

Catheters and methods of manufacture and use

A vascular catheter system is provided with a flexible main body and a flexible shaped tip. The tip is located at the distal end of the main body and has at least a portion configured to deviate from a longitudinal axis when in a relaxed state and towards alignment with the longitudinal axis when a guidewire is extended through a lumen of the shaped tip. The shaped tip is no longer than 1 cm and includes at least three sections. The second section is located distally from the first section, and the third section is located distally from the second section. The second section includes a first material having a first durometer and a second material having a second durometer lower than the first durometer. The first section includes the first material without the second material, and the third section includes the second material without the first material.

Shaped catheter tip for tracking over a guidewire through turns in the vasculature

Balloon catheters that includes inner and outer elongate shafts, each of which is secured relative to an end of an inflatable member. The inner and outer elongate shafts are secured relative to one another at one more discrete connection locations. The balloon bonding locations are disposed radially inward relative to an outer dimension of the outer elongate shaft.

Balloon catheters and methods of manufacture and use

A balloon catheter assembly is provided with an outer catheter, an inner catheter, an outer adapter and a balloon, and is configured such that the balloon resides entirely within a predetermined volume having an outer diameter substantially equal to or less than the outside diameter of the distal end of the outer catheter when the balloon is in a deflated configuration. Methods of using and steering the catheter assemblies are also provided.

Occlusion balloon catheter and methods of fabrication and use

Catheter with inflatable balloon

A high torque vascular catheter system includes an inner catheter, a proximal outer catheter section, a distal outer catheter section, at least one discrete connection point connecting the inner catheter to the proximal outer catheter section, and at least one discrete connection point connecting the inner catheter to the distal outer catheter section. The distal outer catheter section is more flexible than the proximal outer catheter section. Methods of construction and use of the catheter system are also disclosed.

High torque catheter and methods of manufacture

A balloon catheter assembly is provided with an outer catheter, an inner catheter, an outer adapter, a balloon and a support sheath, and is configured such that the balloon resides entirely within a predetermined volume having an outer diameter substantially equal to or less than the outside diameter of the distal end of the outer catheter when the balloon is in a deflated configuration. Methods of using and steering the catheter assemblies are also provided.
