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

A catheter assembly comprises a catheter having a distal end and a longitudinal axis, a stent disposed about the distal end of the catheter, and a stent protector. The stent protector has a stent covering portion disposed about the stent and a catheter engagement portion that removably engages the stent protector to the catheter assembly. The stent covering portion is disposed about the stent without substantially engaging the stent.

Stent protector design

A vascular occlusion, flow restriction, shunt or filter device is disclosed comprising the assembly of at least two, of a number of selectable discrete interconnectable, interchangeable components, at least one component being of the type fabricated from metal strands braided into a tubular metal fabric having an expanded preset configuration and an elongated, collapsed reduced diameter configuration for delivery through a catheter to a treatment site and the device shaped to create an occlusion, flow restriction or shunt when placed in an opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to the expanded preset configuration when unconstrained.

Multi-component vascular device

A vascular occlusion, flow restriction, shunt or filter device is disclosed comprising the assembly of at least two, of a number of selectable discrete interconnectable, interchangeable components, at least one component being of the type fabricated from metal strands braided into a tubular metal fabric having an expanded preset configuration and an elongated, collapsed reduced diameter configuration for delivery through a catheter to a treatment site and the device shaped to create an occlusion, flow restriction or shunt when placed in an opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained.

A catheter system comprises a catheter having an elongate catheter shaft such that a portion of the catheter shaft proximal a stent retaining region defines at least one bend that is bent around the longitudinal axis of a vessel. The catheter also has a side branch guidewire housing, defining a side branch guidewire lumen, and a side branch guidewire that extends through the side branch guidewire lumen.

Twisting bifurcation delivery system

The invention relates to an expandable marker device having a pre-delivery state, a delivery state and at least one active region. The at least one active region incorporates electroactive polymer material. In addition, the expandable marker includes at least one radiopaque material to enhance observation through a medical imaging device.

A stent crimping and coating apparatus is disclosed. The apparatus includes a plurality of crimping blades positioned in a radial array and collectively forming a central crimping lumen, wherein the plurality of crimping blades radially movable to alter the diameter of the central crimping lumen. Each of the crimping blades includes a first surface configured to at least in part define the central crimping lumen. One or more of the crimping blades includes a fluid channel extending therein and a plurality of openings in fluid communication with the fluid channel. The plurality of openings are located at the first surface of the one or more crimping blades and adapted to discharge a fluid into the central crimping lumen.

Devices for abluminally coating medical devices

A medical device having at least one static state, at least one activated state, and at least one active region including electroactive polymer (EAP) capable of fine electro-activated movements. The EAP movements include bending components for proper alignment, rotating components for proper fittings, making components more rigid or flexible, and increasing and decreasing the volume of components. The fine movements allow for highly versatile and adaptable medical devices.

A catheter assembly includes an elongate main catheter branch and an elongate side catheter branch. The main catheter branch includes an arc shape and an inflatable balloon extending along a portion of the arc. The side catheter branch extends along the main catheter branch within a plane of the curvature of the arc of the main catheter branch. A stent can be positioned along the inflatable balloon. The stent includes a lateral branch opening through which the side catheter branch extends.

Bifurcated delivery system and method

A catheter system comprises a catheter comprising a distal portion, a proximal portion and an inner shaft. The inner shaft comprises a medical device receiving region for receiving and carrying a medical device. The retaining device is at least partially constructed of an electroactive polymer. The retaining device is located on or adjacent to the medical device receiving region. The electroactive polymer of the retaining device has an activated state and an inactivated state. The retaining device is capable of retaining a medical device to the catheter and releasing the medical device from the catheter by transitioning between the activated state and the inactivated state.

Stent retaining mechanisms

A bifurcated stent that uses telescoping rings to support or form the side branch lumen. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the need to deploy a bent stent.

Methods for abluminally coating medical devices

A medical device having at least one static state, at least activated state, and at least one active region including electroactive polymer (EAP) capable of fine electro-activated movements. The EAP movements include bending components for proper alignment, rotating components for pooper fittings, making components more rigid or flexible, and increasing and decreasing the volume of components. The fine movements allow for highly versatile and adaptable medical devices.
