An apparatus and method of manufacture includes a helical wire coil and a core wire. The core wire has a first wire portion and a second wire portion. The first wire portion of the core wire extends through the helical wire coil. The second wire portion of the core wire is intertwined with the first helical wire coil to fixedly secure the core wire relative to the first helical wire coil. The core wire is formed from a first material that is non-extensible. The core wire is fixedly secured relative to a distal portion of the helical wire coil such that the core wire inhibits longitudinal elongation of the helical wire coil along a longitudinal coil axis.

A medical pump includes first and second compartments, which are configured to accept respective first and second containers of fluid to be pumped to a medical device, and a paddle, which is fitted between the first and second compartments. The pump additionally includes a control module, which is configured to drive the paddle to alternate between first time periods in which the paddle applies pressure to the first container so as to pump the fluid therefrom, and second time periods in which the paddle applies the pressure to the second container so as to pump the fluid therefrom.

A system for anal or stomal irrigation comprises a reservoir (102) for an irrigating liquid; a catheter (100) comprising a catheter tip for insertion into the rectum or stoma, a thermo sensor (128) connected to the reservoir for obtaining a measure of a temperature within the reservoir, a tubing system and/or the catheter. A control system (103) operatively connected with the thermo sensor is configured to determine a temperature within the reservoir. A method for predicting a temperature in a reservoir for irrigation liquid is also provided.

A method, including ejecting irrigation fluid from a distal end of a probe so as to irrigate tissue, and receiving, over a period of time, initial signals indicative of respective temperatures of the distal end, from a temperature sensor in the distal end. The method also includes formulating from the initial signals a temperature range between upper and lower temperature thresholds and, when a further signal from the temperature sensor, received subsequent to the period of time, is indicative of a further temperature above the upper temperature threshold, raising an alarm that a bubble is present in the irrigation fluid.

Methods and devices for providing liquids to nasal and/or paranasal cavities are disclosed. Probe portions of a first and of a second probe are introduced to a user's first and second nostril, respectively. Each probe has a primary channel and a secondary channel. Fluid is provided to the secondary channels to expand the expandable portions of the secondary channels, seal the nostril openings and expand alar sidewalls of the nostrils. This may reveal ducts that lead to the paranasal cavities. The liquid is provided through the primary channels to the nasal cavity, the liquid being disposed to reach and stimulate the soft palate, and may trigger a swallow reflex to raise the soft palate and exert pressure to the liquid, the liquid may find an escape route through the ducts and into the paranasal cavities.

An enema adapter attaches to a plurality of bottles, shower hoses, or water hoses as the fluid storage vessel or fluid source for body cavity flushing applications, such as enema, douching, or similar applications. The enema adapter directs the flow of water from the into the body cavity for medical or hygienic needs. The enema adapter includes discharge nozzle, a first mounting adapter, at least one discharge opening, and a nozzle cap. The discharge nozzle focuses and directs fluid flow from a fluid reservoir out through the at least one discharge opening into the user's body cavity. The discharge nozzle attaches to the first mounting adapter. The first mounting adapter secures the enema adapter to the fluid reservoir.

A surgical instrument for irrigating a frontal sinus target site of a patient including a handle, an introducer, an irrigation channel, a nozzle, and an actuator assembly. The introducer extends from the handle and defines a proximal segment and a distal segment. At least a portion of the proximal segment is linear and at least a portion of the distal segment is relatively curved. The nozzle is fluidly connected to the irrigation channel, and is rotatably maintained at a distal end of the introducer. The actuator assembly includes an actuator maintained by the handle and connected to the nozzle. Movement of the actuator causes the nozzle to rotate relative to the introducer. The introducer can be sized and shaped in accordance with a size and a shape of a nasal passageway/frontal sinus of a human adult.

Ablation systems of the present disclosure facilitate the safe formation of wide and deep lesions. For example, ablation systems of the present disclosure can allow for the flow of irrigation fluid and blood through an expandable ablation electrode, resulting in efficient and effective cooling of the ablation electrode as the ablation electrode delivers energy at a treatment site of the patient. Additionally, or alternatively, ablation systems of the present disclosure can include a deformable ablation electrode and a plurality of sensors that, in cooperation, sense the deformation of the ablation electrode, to provide a robust indication of the extent and direction of contact between the ablation electrode and tissue at a treatment site.

Disclosed is an auxiliary apparatus for fecal bypass for bypassing and discharging feces in the intestines.

Since supporting portions are connected to a single air flow tube to simultaneously expand when air is injected, and the size of the supporting portions is limited, the auxiliary apparatus for fecal bypass of the present invention does not damage the inner wall and outer wall (mucous membrane and serous membrane) of the intestines.

Also, the present invention comprises a liquid moving tube allowing a therapeutic liquid being refluxed quickly and automatically when the pressure inside the intestines increases, thereby preventing abdominal pain of a patient.

A surgical system can include a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument can include a second channel. A valve coupled to the first instrument controls fluid flow through the first channel. The valve has at least two positions and in one position, the impedance of fluid flow through the valve into the first channel (when the second instrument is not received in the first channel) is substantially the same as when the valve is the other position and the first channel partially blocked by the second instrument. In another aspect, a surgical system can include an outer member and the first instrument can be received within the outer member to define a second channel there between. The first instrument can include a visualization system and an illumination system.
