A testing method for use with a patient stimulation system includes providin g a stimulation system including a patient control unit. The patient control unit initiates and terminates treatment periods. At leas t one period of stimulation to stimulate the patient is automatically provided upon initiating a treatment period. Another method includes a syste m test method for use with a therapy system. The method includes providing a therapy system having a plurality of components; the therapy system physiologically interacting with a patient. A diagnostic self test of a component of the therapy system is performed internally to the system to determine if the component is functioning properly at a time when the therapy system is not interacting physiologicall y with the patient. Apparatus for using such methods are also provided.

Surgical sling delivery system

An apparatus and method of use are disclosed to treat urological disorders. The biocompatible device includes a handle, needle, dilator and sling assembly configured to be minimally invasive and provide sufficient support to the target site. In addition, the configuration of the sling assembly also allows the sling to be adjusted during and/or after implantation. The device and treatment procedure are highly effective and produce little to no side effects or complications. Further, operative risks, pain, infections and post operative stays are reduced, thereby improving patient quality of life.

Transobturator surgical articles and methods

Surgical articles, implants and components suitable for a transobturator surgical procedure are described.

Surgical articles, implants and components suitable for a transobturator surgical procedure are described.

Implant inserted without bone anchors

The present invention discloses an implant (10) for placement in the retropubic space of a patient. Novel methods and assemblies for use in conjunction with the implant are also described. The assemblies comprise at least one deployable member (56) for associating the implant with endopelvic fascia (15) of a retropublic space, and an inserter (80) that is sized and and shaped to associate the deployable member with endopelvic fascia.

Respiratory effort detection method and apparatus

A method of predicting critical points in patient respiration includes monitoring at least one characteristic of a respiratory effort waveform of a patient to detect a respiratory event. A refractory period is defined that includes a hard refractory period during which time the respiratory event cannot be responded to and a soft refractory period following the hard refractory period. The respiratory event outside of the refractory period is detected as a function of a first set of predetermined parameters for the monitored at least one characteristic and the respiratory event within the soft refractory period is detected as a function of a second set of predetermined parameters for the monitored at least one characteristic. The respiratory event may be inspiration onset and the characteristic of the respiratory effort waveform monitored is at least one of slope and amplitude. The refractory period may be defined based on detection of inspiration offset and further may be defined based on inspiration offset, an average respiratory period, and an average time of inspiration. Further, stimulation may be provided in response to a detected inspiration onset. Another method of predicting critical points includes sampling the amplitude of the respiratory effort waveform of a patient. A sample signal is generated representative of at least one characteristic of the respiratory effort waveform based on each amplitude sample. The sample signals representative of the at least one characteristic of the respiratory effort waveform are monitored and a respiratory event is detected as a function of at least two sample signals. Apparatus and systems for use with such methods are also described.
