A balloon catheter which allows for faster preparation and effective purging of air. The balloon catheter includes an elongated, flexible catheter having an inner lumen. A balloon member is secured to an outer surface of a distal portion of the catheter such that an inner surface of the balloon member and an outer surface of the catheter define an inflatable balloon interior. The catheter has an inflation lumen connected to an inflation port and extending distally to a distal end in fluid communication with the inflatable balloon interior. One or more purge apertures are provided in a wall of the catheter, each forming a fluid path between the inflatable balloon interior and the inner lumen of the catheter to allow for purging air from the catheter prior to use in a medical procedure.

Balloon catheter assembly for insertion and positioning therapeutic devices within a vascular system

A vascular access system includes a catheter having an inner lumen in communication with an open distal end; a guidewire at least partially positioned in the catheter lumen and extending out the open distal end thereof, respective proximal and distal stops secured to the guidewire; and a centering device slidably mounted on the guidewire such that the centering device may freely within the catheter lumen relative to the guidewire between the proximal and distal stops, wherein the centering device substantially aligns a longitudinal axis of the catheter with a longitudinal axis of the guidewire proximate the centering device.

Vascular access system and method of use

A catheter having an elongate shaft including a plurality of apertures disposed along at least a length of the shaft to facilitate bending. The catheter includes an inflatable balloon, wherein a subset of the plurality of apertures provides fluid communication from an inflation lumen to the inflatable balloon.

Catheter including a compliant balloon

A catheter shaft with an improved manifold bond and methods for making and using the same. The catheter shaft may include a sleeve disposed, for example, near its proximal end. The sleeve may include a first layer that is attached to the catheter shaft and a second layer to which a hub or manifold may be attached.

Catheter shaft with improved manifold bond

An elongate medical device includes an elongate core and a substantially flat sheet formed into a tubular body defining a longitudinal axis and disposed around at least a portion of the elongate core, where the flat sheet has a length, and where a cross-sectional thickness of the sheet varies along the length of the sheet. The tubular body has proximal and distal portions, and a cross-sectional thickness of the sheet forming the distal portion of the tubular body may be less than a cross-sectional thickness of the sheet forming the proximal portion of the tubular body. A cross-sectional thickness of the sheet forming the tubular body preferably tapers from the proximal portion to the distal portion.

Reinforced elongate medical device and method of manufacture

An intravascular balloon catheter having an ultra soft tip. The catheter includes a braided reinforcement member extending substantially the length of the elongate shaft. A balloon is disposed at the distal end of the elongate shaft. An ultra soft tip is formed from a distal portion of balloon material extending distal of the distal end of the elongate shaft.

Catheter having an ultra soft tip and methods for making the same

An elongate medical device including an inner elongate member, a reinforcing member, and an outer tubular member is described. The reinforcing member may be a helically wound continuous wire including a first portion having a first cross-sectional profile, a second portion having a second cross-sectional profile, and a transition region located between the first portion and the second portion. The first cross-sectional profile may be different from the second cross-sectional profile. In some embodiments, the first cross-sectional profile may be circular or non-circular and the second cross-sectional profile may be circular or non-circular.

Elongate medical device with continuous reinforcement member

Hypotubes such as micromachined hypotubes can include one or more tie layers appropriate for subsequent application of a hydrophilic coating. In particular, a medical device may include a micromachined hypotube having a level of flexibility and a tie layer disposed over the hypotube such that the medical device has a level of flexibility at least substantially equivalent to the level of flexibility of the hypotube.
