Latest Patents

Chi Long's latest patents include the "Lesion Crossing Shock Wave Catheter." This invention provides a catheter designed specifically for treating occlusions in blood vessels. The catheter features at least one electrode pair positioned inside a flexible angioplasty balloon at its distal end. The design allows for a low-profile or coplanar configuration, which reduces the diameter of the device, enabling it to treat tight and hard-to-cross occlusions effectively. The flexible angioplasty balloon is engineered to have an extremely low profile and does not require folding before insertion into the cardiovascular system. During treatment, the balloon can be expanded just enough to immerse the electrode pairs in a conductive fluid before generating shock waves across the electrodes to treat the occlusion. Additionally, the balloon is made from a material with elastomeric properties, allowing it to return to its original low-profile configuration after deflation.

Another patent by Long also focuses on a catheter for treating occlusions in blood vessels. This exemplary catheter comprises a tubular inner member with a base segment that includes a first lumen defining a fluid inlet port and a second lumen defining a fluid outlet port. The extension segment, which is distal to the base segment, has a reduced cross-section. The emitter assembly consists of a first insulated wire extending through the second lumen and a second insulated wire, with a conductive sheath wrapped around them. A cap or balloon is sealably attached to the distal end of the catheter, surrounding the emitter assembly and being fillable with conductive fluid.
