Abstract: An air blower has an inlet muffler and an outlet muffler to reduce the noise of the air blower during operation. Each of the mufflers may have two sections. One section is configured to attenuate high frequency noise and the other section is configured to attenuate lower frequency noise.

A plurality of holes are formed along the tubular wall of each through passage to expose the through passage to the noise absorbent material. A heater plenum may be interposed between the blower plenum and the outlet muffler to heat the air from the blower plenum. A filter at the input muffler filters the air sucked into the air blower.

Abstract: Apparatus and related methods for sequentially positioning and retaining opposing sides of a tissue wound. The apparatus includes a device body having a head portion for positioning between first and second sides of the wound, with the head portion defining first and second retention zones on opposed side of the head portion. The device body further includes first and second approximation arms. The device body further includes a trigger assembly defining three stages of operation. A first stage of operation positions the first approximation arm proximate the first retention zone. A second stage of operation positions the second approximation arm proximate the second retention zone with the first approximation arm remaining in approximation to the first retention zone. A third stage of operation advances a fastener into the first and second retention zones. In this manner, the apparatus sequentially positions the first and second sides with respect to the head portion.

Abstract: A prosthetic insertion apparatus and related methods of use in delivering filled prosthetic bladders through a skin incision and into a surgical cavity or pocket. The prosthetic insertion apparatus imparts control and retention properties to a surgical professional such the prosthetic bladder can be oriented and manipulated into the surgical cavity without risk of inadvertent dropping of the prosthetic bladder and without imparting damaging stress or torque to the bladder. Suitable materials can be utilized that are selected as having advantageous properties including lubricity, rigidity, easily sterilizable, and high strength.

Abstract: A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a control unit configured to operate in a hybrid automated mode during a PD treatment. A processor in the control unit is configured to engage a pump during a fill phase of the PD cycle. The volume of fluid (e.g., dialysate) transferred to a patient line during the fill phase is monitored. After a dwell period, the pump is disengaged at the start of a drain phase of the PD cycle. Disengaging the pump can include: configuring valves of a disposable cassette to bypass the pump chambers of a disposable cassette; activating a bypass valve to shunt the patient line to a drain line; or moving a roller assembly of a peristaltic pump. The fluid transferred from the patient line to the drain line is monitored during the drain phase of the PD cycle.
