20130150716 | Devices, Systems, and Methods for Visualizing an Occluded Vessel - Embodiments of the present disclosure are configured to visualize severe blockages in a vessel and, in particular, chronic total occlusions in blood vessels. In some particular embodiments, the devices, systems, and methods of the present disclosure are configured to visualize the blockage to facilitate safe crossing of the blockage. | 06-13-2013 |
20140163361 | Combination Rotational and Phased-Array In Vivo Imaging Devices and Methods - An in vivo imaging device including at least two imaging modalities. In one aspect, the device includes a rotational imaging system in combination with a non-rotational imaging system. Systems including the imaging device, and methods of forming and in vivo imaging using a flexible, elongate body that includes two imaging modalities are also disclosed. | 06-12-2014 |
20140171736 | Transitional Region Having Cuts and A Skive for an Imaging Catheter - An imaging device for imaging a portion of a patient's vasculature with an imaging element may include a proximal portion having a relatively higher stiffness that provides rigidity for pushing the imaging device through a patient's vasculature, and may include a distal portion having a relatively lower stiffness that enables threading through a curved vasculature of the patient. The imaging device also may include a transition region disposed between the proximal portion and the distal portion. | 06-19-2014 |
20140180055 | ASPIRATING AND REMOVING BIOLOGICAL MATERIAL - The invention generally relates to devices and methods for imaging and aspirating biological material from inside a vessel. In certain embodiments, the invention provides devices that include a body configured to fit within a lumen of a vessel. The body includes an opening. Devices of the invention also include an aspiration channel within the body. The aspiration channel includes a distal end that is connected to the opening. Devices of the invention also include an imaging assembly coupled to the body. | 06-26-2014 |
20140180071 | LOCATING INTRAVASCULAR IMAGES - The invention includes imaging catheters having image collectors co-located with radiopaque labels, methods of using the imaging catheters, and systems for locating the position of intravascular images within the body. In some instances, an angiogram is used to determine the precise location of the co-located radiopaque labels, and thus, the position of the intravascular image. | 06-26-2014 |
20140180076 | SMOOTH TRANSITION CATHETERS - The present invention generally relates to a rapid exchange configuration that reduces the profile of a catheter riding on a guidewire and minimizes guidewire resistance. According to certain embodiments, a body of the catheter includes a distal portion and a proximal portion. The distal portion defines a guidewire lumen and includes a guidewire exit port being open in a proximal direction and leading to the guidewire lumen. A proximal section of the guidewire lumen is straight. | 06-26-2014 |
20140180122 | INTRALUMINAL DEVICE HAVING ENHANCED DELIVERABILITY - Intraluminal devices, especially catheters having variable flexibility elements in a midsection of the device. The devices offer improved deliverability in an intraluminal environment, especially when used in imaging and treatment catheters. | 06-26-2014 |
20140276028 | Integrated Therapeutic Imaging Catheter and Methods - Disclosed herein is an integrated therapeutic and imaging catheter. The catheter comprises an inner member defining a guidewire lumen, a radiopaque balloon assembly, a treatment device operatively associated with an outer sleeve of the balloon assembly, and an imaging device adjacent the balloon assembly. The balloon assembly comprises an inner sleeve surrounding the inner member and an outer sleeve surrounding the inner sleeve. The catheter includes a connection medium, wherein when the connection medium extends through the balloon it is disposed between the balloon inner sleeve and the inner member. The imaging device is disposed adjacent to the balloon assembly and is coupled to the connection medium. | 09-18-2014 |
20150057536 | Balloon Catheter Junction - A balloon catheter junction includes a distal junction on a distal end of a balloon. The junction includes an inner member, a balloon inner sleeve encompassing the inner member and bonded to an interior of a mid-shaft, and a balloon distal leg bonded to an exterior of the mid-shaft. A connection medium is disposed between the balloon inner sleeve and the inner member. | 02-26-2015 |
