Publication number: 20240307662Abstract: Devices, systems, and methods for stabilizing medical tubing protruding from a patient are disclosed herein. In various embodiments of the present disclosure, a medical tubing stabilization device is provided that may include a tube stabilization patch and a complementary medical garment. The tube stabilization patch may be applied to a patient who has medical tubing or a catheter protruding from their body to reduce or dampen movement on the body from the medical tubing in relation to the patient. The medical garment may be worn by the patient and placed in combination with the tube stabilization patch to further reduce the relative movement of the medical tubing. The present disclosure may be directed to reducing the level of medical tubing movement, both externally and internally, that a patient may experience, which decreases the risk of infection caused by catheterization of patients.Type: ApplicationFiled: May 29, 2024Publication date: September 19, 2024Inventors: Adam M.

Publication number: 20240307663Abstract: An expandable medical sheath can include a sheath body having a lumen that extends between proximal and distal ends of the sheath. The sheath can have first and second members where the first member has a different elastic modulus than the second member such that one provides elasticity to the sheath and the other provides column strength. The first and second members can be coupled together in alternating sections to form the tubular sheath or the stiffer members can be embedded in the elastic member along all or a portion of the longitudinal length of the sheath. The sheath can automatically move to an expanded state to allow a larger diameter medical device to pass through the lumen, and once through the sheath can automatically return to its initial diameter.Type: ApplicationFiled: March 26, 2024Publication date: September 19, 2024Applicant: ABIOMED, Inc.Inventor: Christopher Nason Korkuch

Publication number: 20240307665Abstract: A balloon catheter having an elongated catheter shaft defining a fluid drainage lumen and a balloon inflation lumen. The balloon catheter includes a fluid drainage port disposed about the distal end of the catheter shaft in fluid communication with the fluid drainage lumen, and a balloon inflation port disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation lumen. A balloon portion is disposed about the distal end of the catheter shaft in fluid communication with the balloon inflation port. A release device is disposed in fluid communication with the balloon portion and the fluid drainage lumen, and includes an activating member. A tether is attached to the activating member of the release device. Tension applied to the tether activates the release device, enabling fluid flow from the balloon portion into the fluid drainage lumen and out of the body.Type: ApplicationFiled: May 13, 2024Publication date: September 19, 2024Inventors: Bruce A. Gardner, Jeffery A. Gardner, David Allan Swanson

Publication number: 20240307668Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.Type: ApplicationFiled: February 16, 2024Publication date: September 19, 2024Applicant: ABIOMED, Inc.Inventors: Christopher Nason Korkuch, Robert Fishman, Michael Thomas Finnegan, Charles DeLorenzo, Andrew Gentile, Anne Gabrielle McLoughlin, Robert Swierczek, Matthew D'Agostino, Jonathan Barry
