Filed:

Jan 16, 2001

Appl. No.:

09/761367

Inventors:

Michael Finnegan - North Reading MA, US
Long Yu - Rocklin CA, US

International Classification:

A61M001/12

US Classification:

623/003260, 623/001360, 600/016000

Abstract:

A connector for connecting a blood processing device to vascular tissue includes a vascular tissue connecting element that is suturable to a portion of the cardiovascular system for providing a flow connection. A junction ring is affixed to the vascular tissue connecting portion in order to form a substantially shape retaining connecting element. A locking ring for locking the junction ring to a blood processing device includes a coupling element configured to engage a port on the blood processing device so that rotation of the locking ring draws the junction ring to the port and locks the junction ring into a sealing relationship with the port. The locking ring is freely rotatable about the junction ring so that the locking ring can be rotated to lock the junction ring to the port without twisting the vascular tissue connecting element.

International Classification:

A61M 60/50
A61M 60/135
A61M 60/148
A61M 60/205

Abstract:

A blood pump assembly can include various components such as a housing and a sensor configured to detect one or more characteristics of the blood. In some embodiments, the sensor can be coupled to the housing and can include a sensor membrane configured to deflect in response to a change in a blood parameter (e.g., pressure). The blood pump assembly can include a shield that covers at least a portion of the sensor membrane so as to protect the sensor from damage when the blood pump assembly is inserted through an introducer and navigated through the patient's vasculature and/or when the blood pump assembly is inserted into the heart in a surgical procedure. One or more protective layers can be deposited over the sensor membrane to prevent the sensor membrane from being dissolved through interactions with the patient's blood.

International Classification:

A61M 60/205

Abstract:

A guidewire for backloading and inserting a percutaneous pump affixed to a cannula includes a proximal section made of a first material, with a first diameter, a rounded proximal end, and a distal end. The guidewire also includes a distal section made of a second material, with a second diameter which is greater than the first diameter, a distal end, and a proximal end abutting the distal end of the proximal section. The first material of the proximal section is selected to be softer than a material of the percutaneous pump to reduce damage to the pump during backloading. The distal section of the guidewire is configured to be stiffer than the proximal section to insert the percutaneous pump in a desired location without damaging the guidewire.

International Classification:

A61M 29/02

Abstract:

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 that is configured to engage with the step feature of the expandable sheath. When the step feature engages the catch surface, it resists further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. The nature of the interlocking engagement between the step feature and the catch surface allows 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 simply 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.

International Classification:

G01M 17/04
G01M 7/02

Abstract:

This disclosure describes a method for performing BSR testing on a vehicle with an active suspension system, the method including actuating at least one actuator of the active suspension system to induce vibration of a vehicle or at least one component of the vehicle at a first frequency, recording a first acoustic response generated by the vehicle or the at least one component in response to the induced vibration at the first frequency, and analyzing the first recorded acoustic response to identify a presence of one or more manufacturing defects associated with the vehicle or the at least one component. This disclosure also describes a method for characterizing resonance frequencies of a vehicle equipped with an active suspension system.

Abstract:

In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.
