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 system and method for controlling and selecting sources in a room on a network. The system allows a remote viewer to create a virtual presence within the room by providing the available displays, corresponding to the sources, to the remote viewer. The system includes a standardizing technique for improving the communication and overall switching of data for streaming on a network. The system can include a recording server for performing dual recording of the video files in each of a local database and a remote database. A graphical user interface (GUI) display is provided to guide a local user through a medical procedure in the standardized system.

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 two-position handpiece coupling seal is provided. The two-position handpiece coupling seal includes a neck disposed at a first end that is configured to receive an implement. The two-position handpiece coupling seal has a first seal disposed about the neck of the two-position handpiece coupling seal. The first seal is configured to engage with a surface of a housing of a handpiece that uses the two-position coupling seal in a first position. The two-position handpiece coupling seal has a second seal disposed about a bore of the two-position handpiece coupling seal at a second end of the two-position handpiece coupling seal opposite the first end. The bore is configured to receive a driveshaft and the second seal is configured to sealingly engage with the driveshaft when the bore receives the driveshaft.

Abstract: A debrider or other medical device can include an extendable and retractable stylet to ream or unclog a working lumen, a distal portal, or the like. The device can include an elongate tubular body with a proximal and a distal portion. A working lumen can extend from a proximal working lumen portal at the proximal portion of the tubular body to a distal working lumen portal at the distal portion of the tubular body. The device can also include an auxiliary passage, interconnected to the working lumen of the tubular body at an auxiliary lumen portal located between the proximal working lumen portal and the distal working lumen portal. A spoolable or otherwise extendable and retractable stylet can include at least a portion of the stylet being extendable into the working lumen and toward the distal working lumen portal via the auxiliary lumen portal, and the stylet being retractable from the working lumen via the auxiliary lumen portal.

Abstract: A reciprocating drive system for a surgical instrument can include a housing defining a central axis. An inner surface of the housing can define a plurality of helical threads extending along the housing. The reciprocating drive system can include a shaft member defining a motive coupler configured to receive torque from a motive source to rotate the shaft member, and a first follower engaged with, and extending radially outward from, the shaft member, and configured to correspondingly engage the plurality of helical threads, such that rotation of the shaft member translates the shaft member laterally along the central axis.

Abstract: A rotatable surgical instrument, system, and method includes an outer tubular member and an inner tubular member contained, at least in part, within the outer tubular member and configured to rotate relative to the outer tubular member. A distal tip is coupled to and configured to rotate with the inner tubular member, the distal tip forming a channel around a portion of the distal tip. A bearing is rotatably positioned within the channel, wherein the channel inhibits radial and axial movement of the bearing, with respect to the distal tip, along a major axis of the outer tubular member and inner tubular member, and wherein the bearing is configured to inhibit deflection of the distal tip from the major axis.

Abstract: Disclosed embodiments include apparatuses, systems, and methods for guiding a needle to facilitate suturing, such as in surgical anastomosis. In an illustrative embodiment, an apparatus includes a frame configured to counter-rotatably support two generally parallel rollers. A first roller supported by the frame has a flat surface configured to rollably engage a first face of a shaft of a helically-shaped needle. A second roller supported by the frame has a grooved surface defining a helical groove is configured to at least partially receive a second face of the shaft. The second roller further defines a correcting recess bounded by lateral surfaces at a forward end of the groove that tapers to a width of the groove at the forward end. When the leading end is received into the correcting recess, at least one of the lateral surfaces engages and guides the leading end into the forward end of the groove.
