Abstract:
Loading tools for use with medical devices are disclosed. An example loading tool may include a tubular sleeve having a proximal end region, a distal end region, and a lumen. The distal end region may be designed to be engaged with a resilient seal member of a hemostasis valve so that a medical device disposed within the lumen can be passed through the resilient seal member. The tubular sleeve may include a tube wall. At least a portion of the tube wall may overlap to define an overlapping region.
Abstract:
A hub assembly for connection to a medical device. The hub assembly may comprises an outer component having a proximal end, a distal end, and a cavity extending from the proximal end to the distal end. The hub assembly may further include an insert having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end positioned at least in part within the cavity of the outer component. The insert may have a lumen extending from the proximal end to the distal end thereof. The outer component may be formed from a first material and the insert may be formed from a second material different from the first material.
Abstract:
Loading tools for use with medical devices are disclosed. An example loading tool may be suitable for use with a drug-coated expandable medical device. The loading tool may include a tubular sleeve having a distal end region, a proximal end region, and a lumen extending therethrough. The distal end region may include a reduced distal tip designed to interact with a hemostasis valve having a resilient seal member.
Abstract:
Catheters with weeping balloons can be used for various medical purposes. For example, in some embodiments provided herein weeping balloons are used for catheter visualization devices. In some embodiments, weeping balloons are used to deliver therapeutic agents. Weeping balloons can include openings of a selected size and shape through which a fluid gradually flows or “weeps.” The design of the openings can affect performance characteristics such as, but not limited to, fluid flow rate, tear resistance, and mitigation of counter-flow.
Abstract:
A medical system configured for nerve modulation can include an elongate shaft, having a distal end region and a proximal end region is disclosed. Adjacent the distal end region an ablation electrode can be disposed. The system can further include a first optical fiber, having a proximal end and a distal end, extending along an outer surface of the elongate shaft, and in turn a number of (fiber Bragg Grating) FBG sensors therein. The FBG sensors can be positioned adjacent to the ablation electrode. An optical read out mechanism can be optically coupled to the optical fiber to transmit light into the optical fiber and detect light reflected from the FBG sensor. Here, the detected light, reflected from FBG temperature sensors, encodes local temperatures at each of the FBG temperature sensors.
Abstract:
A hub assembly for connection to a medical device having a built in strain relief. The hub assembly may comprise a hub body having a proximal end and a distal end. A lumen may extend from the proximal end to the distal end of the hub body. The distal end of the hub body may have a rounded surface. The rounded surface may have a radius of curvature of greater than 1 millimeter.
Abstract:
A balloon catheter visualization device includes a handle, an elongate shaft, and an asymmetrical balloon. The elongate shaft includes a distal end, a proximal end, and defines a lumen and a longitudinal axis extending from the proximal end to the distal end. The proximal end is coupled to the handle. The asymmetrical-shaped balloon including a distal portion and a proximal portion. The proximal portion is coupled to the distal end of the elongate shaft. The proximal portion has one or more reinforcement features including a layer of material coupled to the asymmetrical-shaped balloon and forming an outer contour at the proximal portion of the asymmetrical-shaped balloon that is asymmetrical to an outer contour of the distal portion of the asymmetrical-shaped balloon.
