Abstract
According to an aspect, an inflatable penile prosthesis includes a fluid reservoir configured to hold fluid, an inflatable member, and a pump assembly configured to transfer the fluid from the fluid reservoir to the inflatable member during an inflation cycle. The pump assembly includes a first pump configured to inject the fluid into the inflatable member according to a first flow rate, and a second pump configured to inject fluid into the inflatable member according to a second flow rate, where the second flow rate is less than the first flow rate.
Claims20
An inflatable penile prosthesis comprising:
- a fluid reservoir configured to hold fluid;
- an inflatable member;
- and
- a pump assembly configured to transfer the fluid from the fluid reservoir to the inflatable member during an inflation cycle, the pump assembly including:
- a first pump configured to inject the fluid into the inflatable member according to a first flow rate;
- and
- a second pump configured to inject fluid into the inflatable member according to a second flow rate, the second flow rate being less than the first flow rate.
An inflatable penile prosthesis comprising:
- a fluid reservoir configured to hold fluid;
- an inflatable member;
- and
- a pump assembly configured to transfer the fluid from the fluid reservoir to the inflatable member during an inflation cycle, the pump assembly including:
- a first pump configured to inject the fluid into the inflatable member;
- a second pump configured to inject fluid into the inflatable member;
- and
- a controller configured to activate the first pump during a first phase of the inflation cycle, the controller configured to activate at least the second pump during a second phase of the inflation cycle.
A method of inflating an inflatable member of a penile prosthesis, the method comprising:
- transferring, by a first pump of a pump assembly, fluid from a fluid reservoir to the inflatable member during a first phase of an inflation cycle;
- detecting, by a sensor, a pressure level in the inflatable member;
- activating, by a controller connected to the sensor, a second pump of the pump assembly in response to the pressure level exceeding a threshold level;
- and
- transferring, by at least the second pump, fluid from the fluid reservoir to the inflatable member during a second phase of the inflation cycle.
