4 results about "Cardiac support" patented technology

To provide suitable devices, systems, and methods for percutaneous pneumatic cardiac support. [Solution] The cardiac support system includes a pneumatic effector implanted beneath the pericardium and across the myocardial surface covering the patient's left ventricle. A port receives an implanted, percutaneously introduced cannula. The port is connected to supply the drive gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and a control circuit that operates the pump to activate the pneumatic effector in response to the patient's sensed cardiac rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port connection end attached to the implantable port.

The disclosure relates to an axial flow heart pump for medical support of a patient. The heart pump can have an impeller housed in an impeller housing. The impeller can have a radius ri and can be configured to rotate about a longitudinal axis. The impeller housing can have an outer radius rh about the longitudinal axis. The impeller housing can have a plurality of longitudinal struts spaced circumferentially to define a plurality of outlet openings. Each of the plurality openings can have an opening arc width less than or equal to a maximum opening arc width wo. Each of the plurality of longitudinal struts can have a width greater than or equal to a minimum width ws. The maximum opening arc width wo can be small enough to prevent a straight object outside of the impeller housing from contacting the impeller.

The invention relates to a line device (105) for conducting a blood flow for a heart support system. The line device (105) has a main part (205), and the main part (205) has a first attachment section (210) at a first end for attaching the line device (105) to a head unit of the heart support system and a second attachment section (215) at a second end for attaching the line device (105) to an outlet unit of the heart support system (100). The attachment sections (210, 215) are shaped so as to be connectable in a form-fitting and / or force-fitting manner. The main part (205) has a structured section (220) with at least one stiffening recess (225) between the attachment sections (210, 215), the at least one stiffening recess (225) being shaped so as to change the stiffness of the main part (205).

Devices, systems, and methods for warming the patient during an ECLS procedure. Depending on the specific need (heart and lung support or pure heart support) the patient may be warmed via a heat exchanger in which the patient bloods comes into close—indirect—contact with a warming fluid or, in a pure Heart Assist procedure, by directly warming the blood of the patient. The proposed solution to both warming methods described above is a centrifugal pump with an integrated heating which has a detachable pump head. The invention allows for a smaller design, simpler handling, using a sterile warming fluid with no air contact, turbulence enhanced heat transfer and includes inherent safety aspects for ECLS patients.
