Described are exemplary embodiments of a handheld, powered positive displacement pipette assembly, including a plurality of syringes of different volumes and a powered positive displacement pipette having unique mechanisms for the retention, identification, operation, and ejection of said syringes.

Powered positive displacement pipette assembly

Described are exemplary embodiments of a syringe identification system for use with a positive displacement pipette, such as a handheld powered positive displacement pipette. An exemplary syringe identification system may include a sensor, such as a color sensor, that is located at or near a distal end of the pipette and arranged such that the sensor is operative to read an identifying marking(s) on a syringe that has been installed to the pipette. The sensor may be a color sensor having an illumination source and configured to read a color code on the syringe. The color code may be usable to identify the syringe to the pipette.

Positive displacement pipette syringe identification system

Pipette syringe

Described are exemplary methods for dispensing liquid from a handheld, powered positive displacement pipette.

Powered positive displacement dispensing methods

Described are exemplary embodiments of a handheld, powered positive displacement pipette having unique mechanisms for the retention, identification and ejection of associated pipette syringes.

Powered positive displacement pipette

Described are exemplary embodiments of a grasping mechanism for a powered, handheld positive displacement pipette, the grasping mechanism configured to grasp and releasably retain the piston head of a syringe that is usable with the pipette.

Powered positive displacement pipette syringe piston grasping mechanism

Described are exemplary embodiments of a syringe for use with a handheld positive displacement pipette, the syringe being releasably retainable by the pipette. Syringe embodiments may be configured to hold different material volumes. At least certain syringe embodiments may include a cooperative adapter that is used to releasably couple the syringe to the pipette.

Syringe for powered positive displacement pipette

Described are exemplary embodiments of a handheld, powered positive displacement pipette assembly, including a plurality of syringes of different volumes and a powered positive displacement pipette having unique mechanisms for the retention, identification and ejection of said syringes.

A pipette check station for checking the calibration or service status of a pipette includes an RFID reader, a user interface with a display and buttons, and a digital interface to connect the check station to additional equipment; the check station optionally further includes provisions to hold pipettes for storage and to charge electronic pipettes held thereupon.

Pipette check system

Pipette check station

An electrophysiology (EP) device suitable for ablating tissue within a patient's body lumen. The EP device of the invention generally comprises an elongated shaft having a distal shaft section with a helical shape and at least one electrode on an exterior portion thereof. One aspect of the invention comprises a method of performing a medical procedure, such as treating a patient for atrial arrhythmia, by forming a lesion using an EP device embodying features of the invention.

Helically shaped electrophysiology catheter

Total occlusions are crossed by passing a guidewire or other penetrating wire from a point proximal to the occlusion into a subintimal space between the intimal layer and adventitial layer of the blood vessel wall. The wire is advanced to a point distal to the occlusion and thereafter deflected back into the blood vessel lumen, typically using a deflecting catheter which is advanced over the guidewire after it has been positioned within the subintimal space. After the guidewire is returned to the blood vessel lumen, the deflecting catheter may be withdrawn and the guidewire is available for introduction of other interventional and diagnostic catheters.
