Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an elongate shaft including a first tubular member and a second tubular member. A balloon may be coupled to the shaft. A first member may be coupled to the first tubular member and positioned within the balloon. A second member may be coupled to the first tubular member and positioned within the balloon. A medical implant may be coupled to the shaft and positioned adjacent to the balloon.

Stent delivery system having stent securement apparatus

A tubular transition member having an annular wall with at least one cut extending through the annular wall is disclosed for controlling a transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member may extend across the junction formed between the stiffer proximal section and the more flexible distal section. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.

Catheter with spiral cut transition member

An angioplasty and stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which or over which there is included on a catheter shaft at least one axially movable or enlargeable body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.

Catheter support for stent delivery

A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

Devices and methods for filtering embolic debris from a body lumen. The present invention includes a filter coupled to an elongate shaft. In some embodiments, the shaft may be tubular so as to be capable of allowing a guiding, therapeutic, or diagnostic device to pass therethrough.

Aortic filter

A spiral cut transition member is disclosed for controlling the transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member has a spiral cut provided therein to vary the flexibility of the transition member over its length. The pitch of the spiral cut can be varied to facilitate a gradual transition in flexibility along the catheter. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.

A stent crimper comprising a plurality of crimping members extending between a first support and a second support. The first and optionally the second supports has an opening therethrough sized to allow a stent therethrough. The first and second supports extend from a base. The crimping members are disposed about the circumference of a circle everywhere along the length of the members. Finally, the flexible members extend through a bore in a die. The die is movable in an axial direction along the flexible members.

Radial stent crimper

A stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which there is included on the catheter shaft at least one body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.

Stent delivery system

A medical device comprises an inner tube and an outer tube disposed about at least a portion of the inner tube. A balloon extends from the distal end of the outer tube. Within the balloon is a first expandable diaphragm, one end of which is attached to the inner tube. The first expandable diaphragm is covered by a retractable sheath disposed about the inner tube. Upon retraction of the retractable sheath, the diaphragm expands to sealingly contact the interior of the balloon in a first contact region and form at least a first compartment and a second compartment in the balloon.

Conformable balloon

A high pressure dilation medical device delivery catheter having a proximal and distal end comprising two tubes mounted generally concentrically about an inner tube. The balloons being characterized as a relatively short inner tube which is inflated with high pressure and a longer outer tube which is inflated with low pressure. The balloons have independent inflation lumens which extend toward the proximal end of the inner tube. A medical device mounting region is disposed about at least a portion of the outer balloon and may have a stent or other medical device mounted thereupon. A retractable outer sheath is further disposed about the medical device mounting region and is operatively connected near the proximal end of the catheter.

Selective high pressure dilation balloon

An apparatus for reducing a medical device such as a stent in size is formed of cooperating crimping dies which are joined via a crimping die moving device. As the cooperating dies are moved together, an inward force is applied to the medical device to reduce the medical device in size.
