20110251676 | Sheath for Controlled Delivery of a Heart Valve Prosthesis - Apparatus and methods are disclosed for controlling deployment of a self-expanding support structure of a prosthetic valve that flares in a proximal direction upon implantation in vivo. A tubular delivery sheath having a side opening that proximally extends within a side wall thereof is used to deploy the prosthetic valve with the self-expanding support structure in a controlled manner. The prosthetic valve is distally advanced within a lumen of the delivery sheath with the self-expanding support structure held in a compressed delivery configuration within the delivery sheath lumen. The self-expanding support structure of the prosthetic valve is aligned with the side opening of the delivery sheath and the prosthetic valve is rotated relative to the delivery sheath whereby the self-expanding support structure is laterally released from the delivery sheath lumen through the side opening to gradually transition from the compressed delivery configuration to a flared deployed configuration. | 10-13-2011 |
20120089047 | CRYOABLATION APPARATUSES, SYSTEMS, AND METHODS FOR RENAL NEUROMODULATION - Catheter apparatuses, systems, and methods for cryogenically modulating neural structures of the renal plexus by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver a cryo-applicator to a renal artery via an intravascular path. Cryogenic renal neuromodulation may be achieved via application of cryogenic temperatures to modulate neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers. | 04-12-2012 |
20120136344 | NEUROMODULATION CRYOTHERAPEUTIC DEVICES AND ASSOCIATED SYSTEMS AND METHODS - Neuromodulation cryotherapeutic devices and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment of the present technology can include an elongated shaft having distal portion and a supply lumen along at least a portion of the shaft. The shaft can be configured to locate the distal portion intravascularly at a treatment site proximate a renal artery or renal ostium. The supply lumen can be configured to receive a liquid refrigerant. The cryotherapeutic device can further include a cooling assembly at the distal portion of the shaft. The cooling assembly can include an applicator in fluid communication with the supply lumen and configured to deliver cryotherapeutic cooling to nerves proximate the target site when the cooling assembly is in a deployed state. | 05-31-2012 |

20120245520 | SPIRAL PERFUSION DILATATION BALLOON FOR USE IN VALVULOPLASTY PROCEDURE - A balloon dilatation catheter for use in a valvuloplasty procedure includes a catheter shaft and a spiral perfusion balloon mounted thereon. The perfusion balloon is formed from an inflatable tube that is in fluid communication with a catheter shaft inflation lumen. The inflatable tube is coiled into a series of windings that in an inflated configuration form a cylindrical or hourglass profile. In the inflated configuration, inner surfaces of the coiled windings of the inflatable tube define a perfusion lumen to allow blood flow through the perfusion balloon. Adjacent windings may be secured together with a flexible adhesive and/or a support weave formed from one or more filaments of material that criss-crosses between the adjacent windings along substantially the entire length of the spiral perfusion balloon. | 09-27-2012 |
20120253471 | Variable Length Airway Stent Graft With One-Way Valves - An airway stent graft includes a plurality of openings through the surface of the graft material and one-way valves at the openings to permit air from outside of the stent graft to enter a lumen thereof during exhalation and to prevent air from exiting the lumen through the openings during inhalation. The stent graft may be of variable length such that the stent graft may be cut to the desired length in vivo. A delivery system includes a cutter assembly to cut graft material of the stent at the desired location in vivo. | 10-04-2012 |
