A cutting balloon catheter including a balloon mounted on a distal portion of a catheter shaft. The balloon includes a cutting member mounted on an exterior surface of the balloon which includes one or more features for providing the cutting member with enhanced flexibility for navigating tortuous anatomy and more closely conforms to the expansion characteristics of the balloon to which the cutting member is mounted.

Cutting balloon catheter with flexible cutting blades

A catheter and handle assembly for use in treating tissue. More specifically, the invention relates to a catheter assembly having an elongate shaft, ablation assembly coupled to one end of the shaft, and a handle coupled to the other end of the shaft. The handle facilitates both axial and circumferential positioning of the ablation assembly via the shaft in an airway, conduit, or vessel for treatment of the tissue. Embodiments include the use of a handle to facilitate the axial and circumferential positioning of the shaft and ablation assembly through and independent of a working channel of a bronchoscope during treatment for pulmonary disease like COPD and asthma.

Catheter and handle assembly, systems, and methods

Some embodiments of an electrical stimulation system employ wireless electrode assemblies to provide pacing therapy, defibrillation therapy, or other stimulation therapy. In certain embodiments, the wireless electrode assemblies may include a guide wire channel so that each electrode assembly can be advanced over a guide wire instrument through the endocardium. For example, a distal tip portion of a guide wire instrument can penetrate through the endocardium and into the myocardial wall of a heart chamber, and the electrode assembly may then be advanced over the guide wire and into the heart chamber wall. In such circumstances, the guide wire instrument (and other portions of the delivery system) can be retracted from the heart chamber wall, thereby leaving the electrode assembly embedded in the heart tissue.

Delivery of cardiac stimulation devices

A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

Prosthetic heart valve formation

An intravascular balloon catheter that may include, for example, a first elongate member having a proximal end, an opening at the distal end and a lumen therebetween, a balloon defining a cavity, the balloon having a proximal waist sealingly attached to the first elongate member proximal the distal end, a distal waist, and a tubular portion therebetween, a second elongate member having a proximal end, a distal end and a lumen therebetween, the second elongate member disposed in the first elongate member and sealingly attached to the balloon distal waist, and a stopper attached to the second elongate member and disposed in the balloon cavity distal the distal end of the first elongate member, the stopper having an outer profile that prevents movement of the first elongate member thereover the first elongate member having an inner diameter at the distal end large enough to permit the passage of fluid therethrough over the second elongate member.

Balloon catheters with increased column strength

A treatment system includes a fluid cooling supply system for chilling and delivering liquid coolant to a patient. The fluid cooling supply system includes a cooling device and a heat exchanger device. The heat exchanger device is biased to the cooling device and is in fluid communication with a treatment device in a patient. The fluid cooling supply system includes at least one biasing mechanism to provide a given biasing force between the heat exchanger device and the cooling device to effectuate and improve heat transfer. The liquid coolant may be circulated through an energy delivery device positioned in an airway of a patient to preserve tissue. The system is controlled to circulate liquid coolant at a given temperature and pressure for a selected amount of time during pulmonary treatment of a patient.

Fluid delivery system and method for treatment

Stent delivery systems and methods for making and using stent delivery systems are disclosed. An example stent delivery system may include an inner member. A sheath may be disposed about the inner member. The sheath may include a compressible coil. A stent may be disposed between the inner member and the sheath. A membrane may extend between the inner member and the sheath. The membrane may be configured to be disposed on the stent. An outer member may be disposed over the sheath.

Stent delivery system

A medical device assembly for incising a stenosis in a blood vessel which includes an incising device, a tubular sheath, and a catheter having an inflatable balloon mounted thereon. The incising device includes a self-expanding scaffold having a plurality of cutting elements projecting radially outward therefrom, and an elongate member extending proximally from the self-expanding scaffold to be manipulated by a user. The self-expanding scaffold is positionable in the lumen of the sheath in a contracted configuration and deployed out of the lumen of the sheath to permit the self-expanding scaffold to expand to an expanded configuration. The inflatable balloon of the catheter is configured to be advanced distally into an interior of the self-expanding scaffold through a proximal opening of the self-expanding scaffold, and inflation of the inflatable balloon urges the cutting elements radially outward to incise a stenosis.

Expandable scaffold with cutting elements mounted thereto

Medical device delivery systems, and related methods and components, are disclosed.
