20090132019 | Bifurcate Stent Delivery Catheter - A bifurcate stent delivery catheter is disclosed that includes a proximal shaft and two distal shaft branches having a bifurcated stent mounted thereon, wherein one or more conventional balloon catheters may be advanced within lumens of the bifurcate catheter to deploy the bifurcated stent. Since no balloons are mounted on the bifurcate catheter, the clinician may use any combination of balloon sizes for deploying various portions of the bifurcated stent and thus custom-select appropriate balloon sizes to best treat the bifurcation. Once a conventional balloon catheter is positioned within a distal shaft branch of the bifurcate stent delivery catheter, each of the distal shaft branches of the bifurcate catheter are constructed to split or otherwise expand in a controlled manner upon expansion of the balloon catheter in order to allow the bifurcated stent to be expanded or deployed. | 05-21-2009 |
20090270714 | Device to Treat Chronic Total Occlusions Using Energy Imparted By External Imaging - A visualization and treatment system for treating a chronic total occlusion. The system includes an elongated member configured to be tracked to the chronic total occlusion. The elongated member has a transducer located at a distal end of the elongated member. The transducer is constructed and arranged to convert a first form of energy into a second form of energy to treat the chronic total occlusion. The system also includes an external imaging system constructed and arranged to create an image of the chronic total occlusion and to provide the first form of energy to the transducer. | 10-29-2009 |
20090299171 | Intraluminal Access and Imaging Device - An intraluminal access and imaging device is configured to image a path of a vessel that includes a chronic total occlusion. The device includes an elongated member having a distal end and a proximal end. The distal end is configured to pass through an inner layer of the vessel so that the elongated member may track subintimally along a side of the chronic total occlusion. The elongated member includes a radiopaque material configured to be highly visible under fluoroscopy. | 12-03-2009 |
20130268064 | Heart Valve Prosthesis Recapture Devices - Heart valve prosthesis recapture devices and methods for recapture are disclosed, which can be used for recapturing a partially deployed heart valve prosthesis. The recapture device comprises a recapture sleeve, configured to envelop and collapse a partially deployed heart valve prosthesis. The recapture sleeve comprises a distal end, configured to be securely attached to a guide wire, and a proximal end, comprising an opening along a longitudinal axis of the recapture sleeve. The opening can be configured to expand as it engages the heart valve prosthesis, and be biased toward a closed configuration. An attachment element can interface with the distal end of the recapture sleeve and be securely attached to a guide wire, such as by crimping. The recapture sleeve can include a support structure comprising at least one spine and a plurality of ribs. | 10-10-2013 |
20140135909 | Valve Prosthesis Deployment Assembly and Method - The delivery systems disclosed herein can create simultaneous movement of an inner and an outer sheath of the delivery system. The delivery systems can generally include a handle assembly and a delivery catheter. In certain embodiments, the inner shaft and the outer sheath can be slidably controlled by a control element in the handle. The handle assembly can include a housing with a thumbwheel acting as the control element. In certain embodiments, movement of the inner shaft and the outer sheath can be caused via a gear-type system. In certain embodiments, the handle assembly can include a rotatable housing. A control element can rotate the housing, which can cause a first boss associated with the outer sheath and a second boss associated with the inner shaft to move in opposite directions. | 05-15-2014 |
20140142688 | Medical Device Delivery System and Methods of Delivering a Medical Device - A medical device delivery system can include a dilator including a tip having a taper in a distal direction, a coupler, and a flap that radially protrudes from the tip. The flap can be configured to bend against a body lumen to cover at least a portion of the delivery system when the dilator is tracked through the body lumen. A medical device delivery system can include a dilator including a tip having a lumen and a coupler having a lumen. The coupler can be configured to securely connect to the tip such that the lumen of the tip is aligned with the lumen of the coupler to allow a guide wire to pass therethrough. Methods for loading a medical device into a delivery catheter are also disclosed. | 05-22-2014 |
20140144000 | Prosthetic Valve Crimping - A crimping tool includes a housing portion defining a funnel segment and a suture locking mechanism positioned to lock sutures therein. One or more sutures can be coupled with a prosthesis and secured to the suture locking mechanism. The suture locking mechanism can be operated to draw the prosthesis through the funnel segment. | 05-29-2014 |
20140236123 | Elastic Introducer Sheath - An elastic percutaneous elastic introducer sheath is disclosed which can locally expand and reduce to accommodate a transcatheter medical device. The elastic introducer sheath includes a non-circumferentially continuous elastic frame, a liner, and a jacket. | 08-21-2014 |
20150025622 | Clocking Valve Retainer - Valve retainers and delivery systems with valve retainers are disclosed. In certain embodiments, a portion of the valve retainer can rotate about a central axis of the delivery system relative to a different portion of the valve retainer. In certain embodiments, a first portion of the valve retainer can include a plurality of first orientation markings. In certain embodiments, a second portion of the valve retainer can include a second orientation marking, which can be aligned with a first orientation marking on the first portion of the valve retainer. | 01-22-2015 |
20150088249 | Heart Valve Delivery Catheter With Safety Button - Valve delivery catheter assemblies including components that limit trauma to the expanded prosthetic valve and body channels as the distal tip of the catheter is withdrawn through the expanded valve and thereafter from the body. Catheter assemblies according to the present invention can include a handle assembly, an introducer sheath, and a distal tip assembly. The handle assembly can include a fixed main handle and two or more rotating handles that allow a user to control the distal tip assembly of the catheter. A safety button can be included on the handle assembly to allow for precise and consistent positioning of the prosthetic valve in the body. A valve retaining mechanism can be included to assist in retaining the prosthetic valve prior to deployment. | 03-26-2015 |
