Patents by Inventor Todd Jenkins

Todd Jenkins has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12274460
    Abstract: The present invention provides a catheter for treating occlusions in blood vessels. The catheter includes at least one electrode pair positioned inside of a flexible angioplasty balloon at the distal end of the catheter. In some designs, the electrode pairs are arranged in a low-profile or coplanar configuration, reducing the diameter of the distal end of the device and permitting treatment of tight and hard-to-cross occlusions. The flexible angioplasty balloon has an extremely low profile and does need to be folded before insertion of the catheter into the cardiovascular system. During treatment, the balloon can be expanded a relatively small amount sufficient to immerse the electrode pairs in a conductive fluid before generating shock waves across the electrodes to treat the occlusion. The balloon can be made of material having elastomeric properties such that it returns to its original low profile configuration when it is deflated following treatment.

  • Patent number: 12232755
    Abstract: The present invention provides a catheter for treating occlusions in blood vessels. An exemplary catheter for treating occlusions in blood vessels comprises a tubular inner member including a base segment with a first lumen defining a fluid inlet port, and a second lumen defining a fluid outlet port. An extension segment is distal to the base segment. The extension segment has a reduced cross-section. An emitter assembly includes a first insulated wire extending through the second lumen and a second insulated wire, and a conductive sheath wrapped circumferentially around the first insulated wire, the second insulated wire, and the extension segment. A cap or balloon is sealably attached to the distal end of the catheter and surrounds the emitter assembly, said cap or balloon being fillable with conductive fluid.

  • Patent number: 12168120
    Abstract: A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. The catheter pump system can include a motor assembly, the motor assembly comprising a chamber and a shaft-driving portion disposed in the chamber. The shaft-driving portion can be configured to impart rotation to the impeller through the shaft assembly. The chamber can be filled with a gas that at least partially surrounds the shaft-driving portion. A fluid pathway can convey fluid proximally during operation of the catheter pump system. A bypass pathway can be in fluid communication with the fluid pathway, the bypass pathway configured to direct at least a portion of the fluid to bypass the chamber.

  • Publication number: 20240358997
    Abstract: A catheter pump system is disclosed. The catheter pump system can include a shaft assembly and an impeller coupled with a distal portion of the shaft assembly. A motor assembly can impart rotation on the impeller through the shaft assembly, the motor assembly comprising a motor which rotates the shaft assembly. The catheter pump system can include a fluid pathway which conveys fluid proximally during operation of the catheter pump system. A seal can be disposed between the motor assembly and the impeller. The seal can be configured to impede or prevent the fluid from the fluid pathway from entering the motor assembly at least about an outer periphery of the shaft assembly. The seal can comprise an opening through which a portion of the shaft assembly extends.

  • Publication number: 20240299051
    Abstract: The present disclosure provides a balloon catheter for treating a stenosis in a body lumen that incorporates at least one shock wave generator located within at least one balloon and at least one channel that permits blood to flow through the body lumen past the balloon while the balloon is inflated. The at least one channel acts as a bypass around the inflated balloon(s) of the catheter such that blood flow through the lumen is generally not fully blocked during a shock wave treatment.

  • Publication number: 20240277994
    Abstract: A catheter pump is disclosed. The catheter pump can include an impeller and a catheter body having a lumen therethrough. The catheter pump can also include a drive shaft disposed inside the catheter body. A motor assembly can include a chamber. The motor assembly can include a rotor disposed in the at least a portion of the chamber, the rotor mechanically coupled with a proximal portion of the drive shaft such that rotation of the rotor causes the drive shaft to rotate. The motor assembly can also comprise a stator assembly disposed about the rotor. The motor assembly can also include a heat exchanger disposed about the stator assembly, the heat exchanger may be configured to direct heat radially outward away from the stator assembly, the rotor, and the chamber.

  • Publication number: 20240260981
    Abstract: A catheter for treating an occlusion in a body lumen includes a movable emitter carrier having one or more shock wave emitters. The one or more shock wave emitters are movable in a longitudinal direction of the catheter along an inner shaft. In a first configuration of the catheter, the one or more shock wave emitters are retracted from a distal fluid-fillable enclosure. In a second configuration of the catheter, the one or more shock wave emitters are inserted in the distal fluid-fillable enclosure.
