INTRO SENTENCE: UCLA researchers in the Department of Radiology have developed a novel vascular sheath that allows surgeons to control the length of the insert and prevent further vascular damage during surgery.
TITLE: Adjustable Vascular Sheath
BACKGROUND: Arterial sheaths are used to gain arterial access and facilitate the insertion of catheters or other equipment for diagnostic and vascular interventions. The invention of these now commonly used devices came as a result of a need to circumvent procedures that commonly used the femoral artery. These surgeries were often intensive and required great recovery time to patients. In contrast, procedures that use sheaths to access the radial artery route allow for shorter recovery time, and lower incidence of surgical complications at the access site. While expandable and adjustable vascular sheaths are available, none currently allow the surgeon to control the length of the extendable sheath.
INNOVATION: Dr. Tafti at UCLA has invented a novel vascular sheath that allows the physician or surgeon to control the length of the vascular sheath, potentially preventing further trauma. This trauma originates from the difficulty of control of the extendable vascular sheath. This disadvantage requires high precision by the surgeon or physician, to ensure that other tissues or veins are not damaged. Therefore, this device allows for greater control without the need extended need for precision by surgeons to the access site.
POTENTIAL APPLICATIONS:
• The main application of these vascular sheaths is to provide access and protect vascular tissue during a variety of endovascular procedures.
ADVANTAGES:
• The only technology of its kind that allows the surgeon to select the length of the vascular sheath
• The vascular sheath can be applied to several endovascular procedures: aneurysm repair, thrombectomies, and angioplasties.
DEVELOPMENT-TO-DATE: The invention is in the conceptual stage of development
