A treatment device for treatment of overactive bladder conditions operates to suction to grasp and conform a mucosal tissue of the bladder wall to a portion of the tissue treatment device, and deliver energy to non-superficial target tissue at a substantially uniform depth from the mucosal tissue. The tissue treatment device incorporates multiple instruments for different functions needed to treat overactive bladder conditions. The tissue treatment device provides simplified interfaces and mechanisms for operating each of the multiple instruments in a controlled manner. Further, the tissue treatment device is configured to have a low and smooth profile that permits the tissue treatment device to be used without a tubular sheath.

An image sensor package includes a substrate, an image sensor, a light-emitting element, and a package body. The substrate includes a plurality of first conductive contacts and a plurality of second conductive contacts. The image sensor is disposed on the substrate and electrically connected to the corresponding first conductive contacts. The light-emitting element is close to the image sensor, disposed on the substrate and electrically connected to the corresponding first conductive contacts. The package body is filled between the image sensor and the light emitting element. The above-mentioned image sensor package can achieve miniaturization, provide uniform illumination, and increase light utilization efficiency. An endoscope including the above-mentioned image sensor package is also disclosed.

An instrument head is provided for attachment to a plurality of instrument handles having different power profiles. The instrument head contains an illumination assembly including at least one LED as well as a drive circuit for detecting a power profile of an attached instrument handle and converting variable voltages received from the attached instrument handle to a constant current for powering the at least one LED based on the power profile. Accordingly, the instrument head enables use with a plurality of instrument handles, including those originally configured for use only with incandescent light sources.

An endoscope having a multiple diameter working section is disclosed. The endoscope includes a housing, a working section, and a rod-lens optical system. The housing is at a proximal end of the endoscope. The working section is integral with and extends from the housing. The working section includes at least a first section and a second section. The first section is contiguous to the housing, and the second section is at a distal end of the endoscope. The rod-lens optical system is positioned at least partially in the first section of the working section and at least partially in the second section of the working section. The endoscope is defined such that the outer diameter of the first section is larger than the outer diameter of the second section.

An electrosurgical waveform having both radiofrequency (RF) energy and microwave energy components that is arranged to perform efficient haemostasis in biological tissue. The waveform comprises a first portion primarily of RF electromagnetic energy, and a second portion primarily of microwave electromagnetic energy that follows the first portion. The second portion further comprises a plurality of RF pulses, wherein the first portion transitions to the second portion when either a duration of the first portion meets or exceeds a predetermined duration threshold, or an impedance determined during the first portion meets or exceeds a predetermined threshold. The waveform is arranged to deliver energy rapidly so that haemostasis can occur in a short time frame in a situation where the maximum available power is limited, or to avoid undesirable thermal damage to the biological tissue.

A medical endoscope system adapted to be inserted into a living body to image an interior of the living body includes: an imaging device that includes a distal end part inserted into the living body to illuminate the living body, and condenses light from the living body to generate two imaging signals having parallaxes; first and second light source units configured to generate first illumination light and second illumination light for illuminating the living body respectively, and supply the first illumination light and the second illumination light to the imaging device; and a display image generation unit configured to generate a display image signal based on the two imaging signals from the imaging device.

An observation instrument comprises an instrument shaft having a distal end and a proximal end, and an optical arrangement extending at least sectionally through the instrument shaft. The optical arrangement comprises at least one optical component that is accommodated in a support shaft. The support shaft is arranged in the instrument shaft in an at least sectionally axially displaceable manner and is preloaded distally.

A camera head includes: a casing including an opening and configured to receive a subject image introduced inside through the opening; an image sensor housed in the casing and configured to capture the subject image; an optical element made of a translucent material and fixed to an inner circumferential surface of the opening by brazing with solder to airtightly seal inside of the casing; and a watertight sealing member fixed to the casing and watertightly sealing the solder joining the casing and the optical element, the watertight sealing member including an annular elastic portion made of an elastic material, and a pressing portion including an annular pressing surface configured to press the elastic portion toward the optical element when the elastic portion abuts on an outer surface of the optical element facing space outside the casing, the pressing portion being fixed to the casing.

There is disclosed in one example an ear irrigation system, including: a control unit including a fluid reservoir; a disposable earpiece constructed to interface with a human subject's ear canal; an extension unit configured to receive the disposable earpiece and to impart fluid to an ingress port of the disposable earpiece; and an umbilical to fluidly couple the fluid reservoir to the extension unit; wherein the control unit is programmed to, responsive to an input from an operator, pump fluid from the fluid reservoir to the extension unit; and wherein the disposable earpiece includes a plurality of vortical fluid guides to guide fluid from an ingress port to an egress port, and to impart to the fluid at the egress port a vortical motion to delaminate a cerumen impaction from the human user's ear canal.
