566 results about "Ovarian follicle" patented technology

An ovarian follicle is a roughly spheroid cellular aggregation set found in the ovaries. It secretes hormones that influence stages of the menstrual cycle. Women begin puberty with about 400,000 follicles, each with the potential to release an egg cell (ovum) at ovulation for fertilization. These eggs are developed once every menstrual cycle.

Follicular transplantation device and method

A hair transplantation device can include a generally tubular guide configured to locate a hair follicle bulb by sliding over a hair shaft down to an upper surface of a hair follicle. The guide can have a blunt distal end configured not to transect the hair follicle bulb. The hair transplantation device also includes an outer tubular member sized and configured to be advanced around the guide. The outer tubular member has a dilator and a harvester. The device can be used in a follicle transplantation method in which the guide locates a hair follicle bulb, and the outer tubular member is slid over the guide. Once the outer tubular member is aligned with the guide, the harvesting portion is advanced, cutting dermal tissue surrounding the hair follicle. The outer tubular member is then withdrawn with the hair follicle, relocated in a recipient area, and the hair follicle implanted.

Follicle Punch For Use With Curled Follicles

A punch that is particularly useful for removing curled hair follicles from a donor site comprises a generally tubular body disposed about a generally longitudinal axis and having a distal cutting end region terminating distally in a plurality of distally-extending circumferentially disposed, generally prong-like members carrying distally diverging cutting edges and separated by follicle-accommodating slits. In practice, the punch is oriented during the extraction process at the donor site so that the curled hair root passes into, and is spared from the advancing cutting edge by, a slit as the punch is inserted into and penetrates the tissue. The punch may then rotated slightly so that the cutting edges cut most of the tissue surrounding the follicle without making damaging contact with the follicle. It may be noted that a rotary motion may not be necessary and, if rotation is desired, it may be in one direction or be in the form of an oscillatory rotary movement, depending on characteristics of the donor site and targeted follicle.
