Income Tax Disclosure [Abstract]
Income Taxes	(13) Income Taxes In accordance with ASC 740, Income Taxes, each interim period is considered integral to the annual period and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period. If, however, the entity is unable to reliably estimate its annual effective tax rate, then the actual effective tax rate for the year-to-date may be the best annual effective tax rate estimate. For the six months ended March 30, 2013, the Company determined that it was unable to make a reliable annual effective tax rate estimate due to the sensitivity of the rate as it relates to its forecasted fiscal 2013 results. Therefore, the Company recorded a tax benefit for the six months ended March 30, 2013 based on the effective rate for the six months ended March 30, 2013. The Company’s effective tax rates for the three and six month periods ended March 30, 2013 were 30.7% and 40.8% respectively, compared to 31.3% and (4.0)%, respectively, for the corresponding periods in the prior year. For the three months ended March 30, 2013, the tax rate benefit was less than the statutory rate primarily due to non-deductible contingent consideration expense related to TCT and Interlace, partially offset by the effect of the retroactively reinstated and extended Federal Research tax credit in the second quarter of fiscal 2013 and the Section 199 manufacturing deduction. For the six months ended March 30, 2013, the tax rate benefit was higher than the statutory rate primarily due to a $19.0 million valuation allowance release related to built-in capital losses, that the Company has concluded are more likely than not realizable as a result of the $53.9 million gain recorded on the Makena sale (see Note 7) and the effect of the retroactively reinstated and extended Federal Research tax credit in the second quarter of fiscal 2013, partially offset by non-deductible contingent consideration expense related to TCT and Interlace. For the three and six months ended March 24, 2012, the effective tax rate was less than the statutory rate primarily due to the tax benefit for charges recorded in the second quarter of fiscal 2012 related to the debt extinguishment loss and discontinuing the Adiana product line. These discrete benefits were partially offset by the net recurring rate impact of the non-deductible TCT contingent consideration compensation expense, non-deductible contingent consideration fair value adjustments for Interlace and Sentinelle Medical and the Section 199 manufacturing deduction. On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted, which retroactively reinstated and extended the Federal Research tax credit from January 1, 2012 to December 31, 2013. As a result, the Company’s income tax provision for the second quarter of fiscal 2013 includes a discrete tax benefit for the previously expired period from January 1, 2012 to December 31, 2012, as well as a benefit related to the tax credit for the quarter ended March 30, 2013. As of March 30, 2013, the Company has recorded $1.62 billion of net deferred tax liabilities compared to $1.76 billion at September 29, 2012. The Company’s deferred tax assets are periodically evaluated to determine their recoverability. The Company has $113.0 million of gross unrecognized tax benefits, including interest, as of March 30, 2013. The gross unrecognized tax benefits increased by $58.1 million from September 29, 2012, of which $53.5 million was a result of uncertain tax positions related to the convertible debt exchange that took place in the second quarter of fiscal 2013. As of March 30, 2013, $59.5 million of the unrecognized tax benefits would, if recognized, reduce the Company’s effective tax rate. The remaining $53.5 million relates to temporary differences that would not affect the Company’s effective tax rate. The Company’s policy is to recognize accrued interest and penalties related to unrecognized tax benefits and income tax liabilities within income tax expense. As of March 30, 2013, accrued interest, net of tax benefit, was $2.2 million and no penalties have been accrued.

In accordance with ASC 740, Income Taxes, each interim period is considered integral to the annual period and tax expense is measured using an estimated annual effective tax rate. An entity is required to record income tax expense each quarter based on its best estimate of the annual effective tax rate for the full fiscal year and use that rate to provide for income taxes on a current year-to-date basis, as adjusted for discrete taxable events that occur during the interim period. If, however, the entity is unable to reliably estimate its annual effective tax rate, then the actual effective tax rate for the year-to-date may be the best annual effective tax rate estimate. For the six months ended March 30, 2013, the Company determined that it was unable to make a reliable annual effective tax rate estimate due to the sensitivity of the rate as it relates to its forecasted fiscal 2013 results. Therefore, the Company recorded a tax benefit for the six months ended March 30, 2013 based on the effective rate for the six months ended March 30, 2013.

The Company’s effective tax rates for the three and six month periods ended March 30, 2013 were 30.7% and 40.8% respectively, compared to 31.3% and (4.0)%, respectively, for the corresponding periods in the prior year. For the three months ended March 30, 2013, the tax rate benefit was less than the statutory rate primarily due to non-deductible contingent consideration expense related to TCT and Interlace, partially offset by the effect of the retroactively reinstated and extended Federal Research tax credit in the second quarter of fiscal 2013 and the Section 199 manufacturing deduction.
