Abstract: An endoscope system can include a control handle, a primary scope, an auxiliary scope, and a guide. The primary scope can extend from the control handle to a distal portion and can be configured for insertion into a passage of a patient, the primary scope can define a working channel extending therethrough. The auxiliary scope can be located at least partially within the working channel and can be movable to extend from the primary scope. The guide can be extendable from the distal portion of the primary scope to guide extension of the auxiliary scope from the primary scope.

Abstract: A modular endoscope system comprises a first modular section comprising imaging and illumination units, and a patient-insertable second modular section that can be detached to the first modular section via an attachment mechanism, wherein the first modular section is positionable at a distal end section of the second modular section and is configured to illuminate and image a portion of a patient anatomy. A method of using a modular endoscopy system comprises attaching a first modular section of the modular endoscopy system to a second modular section of the modular endoscopy system, positioning at least a portion of the modular endoscopy system within a patient, illuminating and imaging a portion of a patient anatomy via the first modular section, removing the modular endoscopy system from the patient, and detaching the second modular section from the first modular section after removal of the modular endoscopy system from the patient.

Abstract: A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position, in the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

Abstract: A method of treating a patient with a bioelectrical system is provided. The method may include inserting a probe into a first position in an anatomy of the patient, the system being provided with a plurality of electrodes; energizing a first electrode of the plurality of electrodes with a measurement level of power; determining a complex impedance in the patient's anatomy; determining whether the first position is a desired position of the probe for ablating a predetermined portion of tissue of the patient, based on the complex impedance determined; and energizing one of the plurality of electrodes with an ablation level of power, the ablation level of power being greater than the measurement level of power. An apparatus for performing BIA on a patient is also provided.

Abstract: A method of treating diverticulitis while maintaining the bioactivity of the diverticulum. The devices and methods include placing an endoscopic device within a colonic lumen relative to at least one diverticulum and inserting a plurality of particles into the at least one diverticulum. The plurality of particles can include magnetic particles, non-magnetic particles, or both. The plurality of particles can partially or totally occlude the diverticulum preventing unwanted material from entering the diverticulum. Additionally, the plurality of particles can include antimicrobial and therapeutic layers that can treat diverticulitis and prevent or minimize diverticulitis from occurring.

Abstract: A therapy device comprises a shaft extending between proximal and distal portions, a surgical instrument located at the distal portion, a handpiece located at the proximal portion, a treatment end located at the distal end of the surgical instrument that can apply photodynamic therapy (PDT). The treatment end includes an applicator to apply a photosensitizer to a surface of a target tissue and a light emitter that can emit generated phototherapeutic light to activate the photosensitizer to ablate target tissue. A method for providing PDT to the target tissue includes inserting the therapy device into the patent, applying the photosensitizer and phototherapeutic light to a surface of the target tissue, and removing the device from the patient.

Abstract: An electrotherapeutic device can be configured for at least partial insertion into a patient. The device can include a shaft including a proximal portion and a distal portion, a gas-delivery lumen extending between the proximal portion and the distal portion of the shaft, and one or more electrodes located near the distal portion of the shaft. The electrodes can include a plasma activation electrode for generating plasma from gas delivered to the distal portion of the shaft via the gas-delivery lumen, and an ablation electrode for generating electromagnetic ablation energy. The medical device can be used in a method of treating endometriosis including delivering a gas toward an in vivo treatment site within a patient, generating plasma from the gas on or near the in vivo treatment site using a plasma activation electrode, exposing the treatment site to the plasma, and applying electromagnetic ablation energy to treat endometrial tissue.

Abstract: A surgical needle comprising: (a) a sensor; (b) a distal tip with the sensor being located at the distal tip; (c) a needle advancing mechanism that is adjustable to change an insertion depth; and (d) a control unit in communication with the needle advancing mechanism; wherein the sensor provides a signal to the control unit regarding a thickness of a feature of interest and the control unit controls the insertion depth based upon the signal from the sensor so that the insertion depth into the feature of interest is varied or the control unit prevents the needle advancing mechanism from activating.
