Patent number: 10779885Abstract: Systems and methods for delivering microwave energy to skin are provided, such that a focal zone of destructive heat is generated in the upper sub-dermis, mid-dermis, and/or lower dermis. This microwave therapy may be used for hair removal, treatment of acne, skin tightening, treatment of toe nail fungus, or sweat reduction. According to one embodiment, a system can include a microwave applicator having a distal treatment portion that includes at least one microwave antenna, a cooling system, and vacuum features. In some embodiments, the interaction between incident waves transmitted from the microwave applicator and reflected waves may be used to generate a standing wave with a peak energy density in selected regions of the dermis.Type: GrantFiled: July 24, 2014Date of Patent: September 22, 2020Assignee: MIRADRY.

Patent number: 10154880Abstract: Various high-strength microwave antenna assemblies are described herein. The microwave antenna has a radiating portion connected by a feedline to a power generating source, e.g., a generator. The antenna is a dipole antenna with the distal end of the radiating portion being tapered and terminating at a tip to allow for direct insertion into tissue. Antenna rigidity comes from placing distal and proximal radiating portions in a pre-stressed state, assembling them via threaded or overlapping joints, or fixedly attaching an inner conductor to the distal portion. The inner conductor is affixed to the distal portion by, e.g., welding, brazing, soldering, or by adhesives. A junction member made from a hard dielectric material, e.g., ceramic, can be placed between the two portions and can have uniform or non-uniform shapes to accommodate varying antenna designs. Electrical chokes may also be used to contain returning currents to the distal end of the antenna.Type: GrantFiled: January 5, 2017Date of Patent: December 18, 2018Assignee: Covidien LPInventors: Mani N. Prakash, Francesca Rossetto, Anthony C. Lee, Steven Kim, Ted Su, Jonathan L. Glassman

Patent number: 9647734Abstract: Efficient algorithms for estimating LSFCs with no aid of SSFCs by taking advantage of the channel hardening effect and large spatial samples available to a massive MIMO base station (BS) are proposed. The LSFC estimates are of low computational complexity and require relatively small training overhead. In the uplink direction, mobile stations (MSs) transmit orthogonal uplink pilots for the serving BS to estimate LSFCs. In the downlink direction, the BS transmits either pilot signal or data signal intended to the MSs that have already established time and frequency synchronization. The proposed uplink and downlink LSFC estimators are unbiased and asymptotically optimal as the number of BS antennas tends to infinity.Type: GrantFiled: November 12, 2014Date of Patent: May 9, 2017Assignee: MediaTek Singapore Pte.
