Atraumatic iol insertion cartridge opening

This intraocular lens (IOL) injector cartridge has a proximal opening in a main body for receiving an IOL. The main body has a lumen that extends longitudinally to a distal end having an opening smaller than the IOL. Passage through the lumen compresses or rolls the IOL so that when the distal end is inserted through a small incision in the eye the IOL can be expelled into the capsular bag. The distal end of the cartridge is beveled with a leading tip in front of a trailing heel. The characteristics of the beveled end are such that damage to the IOL is reduced. The bevel may be straight or curved and includes a distal face defined by the thickness of the distal end between the lumen and an exterior surface. The distal face may be flush with the bevel or chamfered. An inner corner angle between the distal face and the lumen is ≧60° to reduce the chance of scratching the IOL as it passes out of the distal opening.

Automatic sensitivity control in an implantable cardiac rhythm management system

ABSTRACT OF THE DISCLOSURE A method and apparatus for automatically adjusting the sensing threshold in an automatic implantable cardioverter/defibrillator with pacing capability. Fixed sensitivity is used for a specified interval following each pacing pulse and automatic sensitivity adjustment is used whem spontaneous cardiac depolarization is detected. For spontaneous cardiac depolarization, the sensing threshold is automatically adjusted to a value proportional to the amplitude of the sensed cardiac signal. The sensing threshold continuously decreases between sensed cardiac depolarizations, ensuring that a lower level cardiac signal will be detected. When a pacing pulse is delivered, the sensing threshold is set to a fixed value and held at that value for a predetermined period of time such that the sensing threshold will not be affected by the cardiac response evoked by the pacing pulse. At the end of the predetermined period of time, the sensing threshold is decreased as it would following a spontaneous cardiac depolarization.

Sterol regulatory elements

STEROL REGULATORY ELEMENTS ABSTRACT Disclosed are discreet functionally translocatable DNA segments, termed Sterol Regulatory Elements (SRE's), which are fused to heterologous structural genes to provide sterol regulatory capability to the thus formed hybrid gene. The hybrid genes respond to sterols by decreasing the production of messenger RNA. The SRE segments contain as their primary functional nucleotide sequence, a 16 bp sequence referred to as direct repeat 2, isolated from the 5' regions of the human LDL receptor gene. DNA segments which include this 16 nucleotide long sequence similarly confer sterol regulatory capability to previously known promoters such as the HSV TK promoter. Also disclosed are discreet sequences which confer positive transcription promotion to heterologous structural genes and promoters without conferring sterol responsivity. Methods are disclosed for employing these genetic control elements in a myriad of embodiments which provide for a fine-tune control of heterologous genes. Methods are also disclosed for employing the SRE in a screening assay for drugs capable of stimulating the cell to synthesize LDL receptors.
